Dell Inspirion 7577

The hyperthreading bug is very specific, even if intel didn't patch their microcode I would venture to say 99% of the people would be just fine. Assuming Dell has put the microcode that's been available since before the 7577 came out then it's ok, that's assuming that microsoft hasn't pushed it via a windows update already...

 

I would like to update my stuttering adventures. The previous drivers seem to be working flawlessly besides the fact that Geforce Experince doesn't not want to blood open. This issue seems to be related to the Windows Fall update and 382+ (in some cases 385+) drivers. More can be found in this lengthy thread on nVidias's forums.

 

Godspeed dude. I haven't even had the time to put my machine through its paces, so I'm going to be really devastated if my rig suffers from similar issues as yours. I have been diligently researching how to gut Windows 10 and do a flawless clean install with all the fluff and BS removed however.

That NVIDIA forum thread that I only briefly read the first handful of posts from makes me hate Windows 10 even more. I thought Windows 7 had an annoying number of quirks and BS to deal with to get it installed and up and running flawlessly (there are some updates that corrupt and ruin a clean Windows 7 install and break the theming and aero that are irreversible- I found out the hard way during my most recent reformatting adventure this past summer on my old laptop that now has a flawless Windows 7 installation I have been more than thrilled with).

But seriously, these Windows 10 quirks and intrusions are enough of a PITA to warrant an omni-boot setup with Windows 7 setup just for gaming imo. On a solid state system with O/S's that can hibernate it's really not that hard to jump between them effortlessly when you want to game versus doing other stuff. It does suck having to maintain parallel installs of certain apps and utilities though, but Windows 7 has far fewer graphics driver bugs than Windows 10 does.

@FireLantern based on what I am reading in that NVIDIA thread, it sounds like some sort of a memory leak causing a buffer to back up... You might benefit from installing Bitsum's Process Lasso and running in 'High Performance Mode' with 'SmartTrim' enabled, but that's a far cry. It does dynamic scheduling tweaking to prioritize and prioritize certain services/threads. The SmartTrim function cleans your memory being used by apps, so it could help mitigate some aspects of a memory leak. All said though, it is really just a bandaid and not an actual solution... That would likely need to come from NVIDIA / M$ / Intel / Dell.

 

On my Inspiron disabling integrated Intel graphic adapter from Device manager solves the stuttering issue. Of course this is not a solution, but it proves Windows has probably nothing to do with it and it's just drivers.

Edit: I now see you are talking about in-game stuttering, so ignore my post, looks like a different issue

 

But that should mean that simply using the nVidia control panel and forcing the game to run on the high end GPU should fix the issue as well yet it doesn't.

Anyhow it's weird and I'm just glad that I found what exactly is causing the issue and now I can take a deep breath and relax with my outdated drivers cause I know it's not a hardware issue.
It does suck tho, I want to play Destiny 2 sooner or later and without the latest drives the performance is going to suck.

@Maleko48
I might be doing the dual boot thing if this won't be fixed in a month or so when I'll be getting the second SSD. I must say that I did get very user to using windows 10 and it feels weird just thinking of switching to something else now.
Maybe going to Windows 8.1 could also be a solution, I'm reading that there are no driver issues there and it's shell is closer to Windows 10 and it doesn't have the Aero thing going on. Anyhow the improtnat thing would be to stop M$ from forcing me to install their "feature" updates.

A thought crossed my mind this morning... Do you have Google Chrome installed or Spotify installed or any other program that makes use of GPU/hardware rendering, even if it's the Intel GPU it's using? If you go into Google Chrome's settings: [ MENU(...) > SETTINGS > ADVANCED > SYSTEM > "Continue running background apps when Google Chrome is closed." ] Is yours set to ON or OFF? I believe the default is ON. The reason I mention this is because I thought I remembered reading somewhere recently that Chrome can actually be the cause of system-wide stutters and ****ty behavior for some people and I believe that setting is ON by default. I always make it a point to turn mine off. There is also an [ additional setting: "Use hardware acceleration when available" ] you could try toggling OFF as well if you wanted. Or better yet, try a temporary uninstall of Chrome maybe?

The same goes for Spotify or any other app that likes to run in the background, has a helper process that launches at startup (even if you don't actually see it in your task bar tray), and also uses hardware acceleration (even if it is only Intel's GPU it uses). Then again..... It could also just be all the ****ty Windows 10 services that run in the background based on a lot of reading from that link (and subsequent splinter links) I was reading up on last night. In particular the one setting that turns your machine into a peer-2-peer node for uploading Windows updates and installs to other users in the background.

But regardless pretty much all of the issues seem to ultimately stem from the CU and FCU that M$ forced on everybody prematurely. If you are willing to do another clean install there are certainly ways to avoid taking the updates... It just takes a very methodical and careful approach. Also when I get around to RE-clean-installing my machine, I will be making frequent O/S partition clones along the way since I keep ONLY my O/S on a minimally-sized partition, it makes it practical to back it up frequently in case I **** anything up, I can easily revert back and not have to reinstall much if anything.

 

Is it necessary to create a backup of the PowerManager or can I just download it here?
http://www.dell.com/support/home/us/en/4/Drivers/DriversDetails?driverId=DY59W

Also, is anyone else aware of some critical dell software we need for a clean install aside from regular drivers?

 

What you'll end up downloading from here is a Power Manager Service, which is also required by actual application.
I've got service from Dell's site, then it said that I should go to Windows Store and download the app from where, and after that I had my Power Manager up and running.

Maybe someone know a way to make this UEFI interpret hardware clock in UTC format, rather than localtime? Is there even a way to do so? It wouldn't be much of a problem to simply ignore what UEFI says to me in that "Date/Time" tab, but Power Manager uses this time for battery charge control.

P.S. To the list of fun things on this laptop: Fn+H switches LED on the front from battery indicator mode to drive load indicator.

 

The Dell Power Manager I posted earlier in this forum was straight from my 7577's stock factory backup. Dell's website only hosts the Dell Power Manager Service as @Shorrer mentioned. I don't know if Dell has fixed it yet, but after installing the DPM Service, it wants you to download and install the Dell Power Manager from the Windows store, however the Windows store (at the last time I tried) was throwing an error saying the Dell Power Manager app wasn't for the version of Windows we were running. Hence, I posted the actual Windows Store Dell Power Manager executable from my factory stock backup since I had it and others already destroyed their stock installs without first backing them up and had no other way of installing it the Dell Power Manager app from the Windows Store. This laptop has been on the backburner for me with school in full swing and almost over for this semester, so it will likely be another week or few until I can get around to actually using it for real and re-installing everything again. Like I said, there is a chance Dell has addressed this with updates to their drivers and/or Windows Store app by now. I haven't been keeping up for the past few weeks because of school.

 

So how is everyone satisfied with their 7577s for now?
Besides driver issues (audio issues aswell and those too are all driver related) the only thing that is bothering me is the screen wobble (maybe I just type on the keyboard a bit too aggressively) and that sometimes the fans kick in while doing low resource work but my guess is that some good undervolting can fix that easily.

Overall tho I am very satisfied with the performance, I'll also open the laptop up over the weekend and get a look at the internals a bit. Did anyone try repasting the CPU/GPU yet?

Is there a keyboard shortcut for turning the track pad on and off?

1.) Try reading the Dell User Manual first

2.) Google is your friend:

http://www.intowindows.com/3-ways-to-disable-touchpad-in-windows/

3.) Use AutoHotKey to automate a macro

 

Completely satisfied.
Checked performance in GTAV on almost full settings (4xTXAA instead of MSAA). Looks cool, plays at ~60FPS (sometimes drops to 30, actually), temps is 65C for GPU and ~70C for CPU, which is okay for me, so I'll pass on repasting for now. Haven't really had enough time to test it with other games. As for pure CPU performance I only had it running prime95 for several hours (not in stress test mode), and it showed 6.1 ms per iteration. That's okay as well, I think, though my desktop i5-2500k spends around 4.5 ms per iteration, but it's overclocked to 4.4GHz and that is far ahead of 3.5GHz on this processor (but it's TDP is like five times lower, so it's more effective and for notebook that's really important). SSD speeds are fast. Yeah, that write speed of 300MB/s is far from the speeds of other NVMe drives, but the read speed is here and working alright. System wakes from hibernation really fast, and games also can load pretty fast. There is HDD that constantly tries to spin down, and I hear it kicking in when I access it, but, well, I consider that a fun thing, not an annoyance. What else? Battery seems okay, I didn't really measured the times, but it's enough for some 3D graphics on Intel like very light games and AutoCAD for several hours, as well as some Visual Studio and stuff. ExpressCharge is, well, express. Charges battery as advertised, from ~20% to 80%+ in one hour, but I think this can kill the battery faster, so I've configured Advanced Charging (there is little to no info about what Adaptive mode really does, so I'm a little afraid of it). Wi-Fi, yeah, Wi-Fi is cool. I'm getting my full internet speed from 802.11n router, and because of that I don't need to run a LAN cable from it to notebook. Fans are quiet on low loads, though they're always turned on. Yeah, they sometimes make a blow-out when on low load, that's probably a trade for their relative silent running at 99% of time. Can't say anything for fan loudness while gaming because I'm used to my desktop which sound, of course, way louder. They quickly return to their quiet state after load (couple of minutes, probably), but someone here reported that his device was staying loud for quite the time, so maybe I'm lucky here. Fingerprint sensor works, though once they refused to unlock my notebook. Build quality is cool, I get no screen wobbling, and I've used to type really hard, there is some little gap between the palmrest and right side of body (I can see metallic USB-C port). Opening it with one hand on the center of display because it bends otherwise, and that's probably my only concern with this chassis. Keyboard is cool, backlight seen through the gaps between the key itself and palmrest on my device, and that's the only somewhat bad thing I've got on keyboard (and some keys aren't uniformly filled with light, so they appear a little darker, though that is minor thing). Overall, I've typed this text on it, and I'm far from ending it. Seems okay even after old cheap chinese noname membrane keyboard with some reseller's brand on it, which had bigger stroke depth and generally other feel of keys, but I had no discomfort while using this one, even at the very first day. Someone might say that arrow keys are bad here, but I've typed some code on some other notebook today, which had full-sized arrow keys, but they were so inline with other keyboard keys (I mean that the gap between arrow keys and the rest of keyboard was equal to gap between ordinary keys) that I've got no tactile cue of where does the keyboard ends and additional keys start and found myself pressing them when I didn't wanted to. Here, on 7577, the keyboard is engineered quite cleverly - there is the gap between numpad and main keyboard, and there is blank areas around arrow keys, so I don't need to look at the keyboard to find them, and that would be very, very annoying. Also Fn+ArrowKeys are binded to Home/End/PgUp/PgDown, which is convenient (Fn+R is SysRq, in case someone is angry to not find that key on his notebook). Touchpad is cool, whether it is Windows' Precision stuff that makes it cool or whatever. It's easy to lay my hand on it while typing and don't be afraid to accidentally select half of the screen and close something. You can even wipe some stuff from it with hand and it wouldn't make something awful in your system.
Okay, well, I think I've said a little too much, but there is something else I wanted to point out, for those who use Linux and Windows with UTC and also use Advanced Charging - UEFI time is a localtime, and Advanced Charging relies on it, so you might find your setting a little offsetted after all that. Also for UEFI features there is SecureBoot Key Management screen, where you can load up your own keys for your signed bootloaders, and that's pretty neat. Then the description of Advanced Charge mode is a little misguiding in UEFI -- it doesn't say that your battery wouldn't be charged for more that 90% outside of working hours. Other than that there is just enormously great feature that allows you to add custom UEFI loaders from any folder on your ESP - thanks for that, DELL, maybe someday it'll save me some nerves. And there is some Thunderbolt security settings, which may restrict it to work in DisplayPort mode -- maybe someone would find it useful. Also there is an option to skip POST automatically if UEFI doesn't think that it's required. Turned it on for now, experienced slightly faster loading times, but it probably isn't a good trade with a load check that might show some errors. Also, about errors: while doesn't wielding a PC speaker (that beepy thing), they've made error output through the front LED, which will blink some times with amber color and some more times with white color. There is some hidden meaning of Caps Lock LED, which turned on me once when I've got a system crash after undervolting attempt and when Linux failed to boot because of me being dumb. Some sort of Caps Lock LED of System's Doom or whatever, if someone has more info on it then it would be interesting to know what it can show. Ah, forgot about main speakers: they're okay and loud, though I haven't tested them much. Alert beep in system once scared the stuff of me, beeping with it's full volume, so you can take that (also, beep volume wasn't showing up in ALSA, so I haven't found a way to lower it).
So, what I would have changed:
- Added some sort of moon icon on Insert key, as Fn+Insert is binded to be the sleep button and that icon would make it more obvious for users
- UEFI time set to UTC, even better -- two switchable modes.
- G-Sync, but that would made it so much more expensive that I'm probably glad that this feature isn't here (it isn't here, right?)
- Just a little smaller, a little, less than a half of centimeter here in width and depth, just that
Nothing critical, yeah.
That's probably all that I have managed to get on it in almost a week of usage. Absolutely satisfied.
Sorry if that's too much of unstructured text to read, but I think that I wanted something like this when I was searching some info about it or about 7567. Hope it'll be useful for someone

 

The more reading I do, the more motivated and inspired I am to tear into mine and repaste, among other things like adding/upgrading thermal pads and additional heat sinks. I like custom mods of that nature.

 

Hello all. I tried to oc gpu with msi afterburner on my 7577 i7 gtx 1060
Settings HERE
I had to undervolt cpu with xtu and set it -0.115v
Some tests by stock and after overclocking :
Userbenchmark BEFORE and AFTER
Unigine Valley BEFORE and AFTER

I tried up to 450mhz to memory and 220 mhz core, but so I got some issue and freeze system..
Keep settings on Core 200 - Memory below 450 no problems,and gaming performance enhanche. GPU allows you to do it

 

Hi guys, i've be reading a lot about the 7577 but I'm still not 100% if I should get it over the clevo p650. Thermals are my biggest worry and I've seen people complaining about temperatures hitting 76c on the cpu and 74c on the gpu. Those temps are very close to the p650 and it has the full 1060 instead of the mq one. Can anyone give me a light here? Which one do you guys suggest? Their price difference isn't too big where I live.

I'm sorry for asking such question, I'm sure it has been asked a 100x times before but I couldn't find anything on the forum.

 

Hello,
Which config do you want to purchase for the Inspiron ? I bought the one with i7 and 1060 maxq and the thermals management is awesome (I bought it in France). I was a bit skeptical at the beginning but I just finished a 2-hours World of Tanks session, and I could not feel any heat on the keyboard ; regarding the fan noise, it is really acceptable. What games do you intend to play ?

Regarding this nice laptop, I have a question about the 1080p screen. The colors are a bit yellowish, and I am wondering if it is possible to improve the situation on this point ? Did some of you face this issue ? Any solution to get more vibrant colors ?

Thanks in advance for your help and spend a nice weekend on this good laptop

 

The best thing about 7577 its precisely temps...I dont know what do you read
My gpu never above 61/62°

 

Hey 7577 owners, I am developing a more structured 7577 thread I hope to fill with all sorts of goodies and knowledge over time, but first I need to finish it and attract the best of the best minds who own this machine.

SEE HERE: http://forum.notebookreview.com/thr...-details-pics-of-internals-optimizing.811380/

If nothing else, it will serve as my personal thread that helps me keep everything organized and optimized on my machine between system and drive reformats.

I am trying to make it easy for us to point other owners with issues, questions, concerns, ideas, etc. to specific resources. For now, I would appreciate any feedback on the Table of Contents I am developing.

I need to lock in the main section headings sooner than later so the reference codes don't end up changing later and making thread posts that reference them point future users to incorrect resources. Worst case scenario, the structure codes can get scrapped in the future and the ToC will still remain useful for those willing to read through it.

ex.) " Hey @DJav-7 click on ToC resource [Dc1] to grab the DDU utility for performing a true clean install of your graphics drivers. "

Thanks!

 

Oh, it seems a great idea

 

that looks really nice , I am also in process of Undervolting CPU and overclocking GPU , will post my results soon

 

Hi, a couple of questions:
1) A bit of a weird one. Do you feel those bottom rubber feet when you place the laptop on your legs, say, sitting in an armchair? Are they uncomfortable?
2) Do you notice the big bezels in everyday use? Does anyone get kinda claustrophobic using the laptop or they look so intimidating only on pictures?
3) Do laptop's fans spin up when you watch twitch streams? Are they controlled gradually or they just go max rpm whenever?

 

Hi Kreo,
Just simple answers from my personal experience on this laptop I received last week
1) I cant feel the rubber feet when placing the laptop on my legs. I am writing to you in this position actually, and it is not uncomfortable at all.
2) I agree the bezels are too big, but usually I forget it after a couple of seconds when I switch on the laptop. As it is quite bulky, the screen is big enough to make you ignore the bezels size Anyway I like the laptop layout, but it is personal.
3) Based on my own experience, I only can hear the fans when playing games. Watching videos or just typing like I am doing now does not put the fans on. Even in games the fans noise is not so loud. I played Max Payne 3 yesterday, and I could do it without headphone, the speakers were enough (not the most recent game I agree but it is quite demanding and I played with ultra graphics). And from what I experienced the fan control is gradual.
Have a nice evening

 

Has anyone added a 120hz panel to this laptop and if so which model.

 

Is anyone have an issue watching twitch streams on chrome? After a while of watching a stream, it'll go black and say "2000: network error" This doesn't happen on my other laptop though.

Chrome has been kind of buggy in general for me lately.... and that's on my old laptop.

 

The mystery with my Realtek audio drivers not working and MaxxAudio being not installable seems to be solved. I was using the N version of Windows Pro, which is made for EU and doesn't include Media Player and IE. Apparently Realtek drivers need something from Media Player that is missing and in turn could not install MaxxAudio. I tried installing Media Player libraries on top of the N version but it didn't solve the issue. Reinstalled with regular Windows 10 Pro (exactly the same build, but a non-N version) and all worked like a charm.

 

Thanks for sharing that valuable information. I would have never considered that angle.

 

Hello!

I'm also interested in this laptop.

Contacted internet shop (here in Baltics) that can order directly from Dell and i asked quote for i7 + GTX 1060 max-q model.

I was told they don't have any with 1060 Max-Q but instead i can get one with GTX 1060.

Does it mean Dell now sells regular 1060?

I also contacted directly to Dell asking the same question and i was told it comes without Max-Q design.

I am super confused now about this Max-Q thing.

Are all 7577 with 1060 Max-Q design and everyone (most resellers) including Dell itself are misinformed about this fact or as of this moment Dell updated hardware?

 

Thanks for the reply.

By the way - those of you who have the 256gb Samsung SSD version, can you comment on its reallife performance? I've heard that it doesn't include fast SLC cache unlike its sister 960evo or bigger capacity PM961's, and that it can slowdown to HDD-like speeds while copying large files.

 

Ot is a 60W 1060, which is im fact the Max-Q version.

 

Dell and many retailers or resellers don't know their heads from their ass. It's got the Max Q GTX 1060.

 

Kind of pissed with Dell right now... sent my 7577 in for repair of a faulty keyboard (1 single key not responding properly) and they can't communicate to save their life. Originally quoted it would be a 7 to 12 day process. Today is day 25 (since initial phone call to start the whole repair process). My point of contact is useless, doesn't know how to respond to questions at all. They took my system off "hold" status and it was estimated to have already been repaired and shipped back to me more than once, but the due dates just keep on slipping by. Smh... I knew this was not going to be fun, but I didn't think it was going to be *this* bad.... At this rate I will be lucky to have my machine that I ordered October 30 back before Christmas! (-_-)

Complain and ask that they send you a new system instead of your old one with a new warranty. Ask @GoNz0 for tips, he's had more new Dell's for free than anyone I know.

 

This is why I prefer to do these kind of fixes myself, but it is a little bit different when it is a brand new machine that you paid for and didn't receive in full working order and don't want to needlessly void the warranty either. Thanks for the tip. They are supposed to be calling me within 48 hours according to the update they just posted a little bit ago today. I am unfortunately at school all day today scrambling to finish all my math homework. :-\ But ffs, it's a straight-forward keyboard replacement and according to the messages "the parts are backordered". Really Dell?? Reallllly?

 

Demand a new one now or a full refund now, simple as that, as soon as the rep tries being arsy tell them you have already filled in the credit card chargeback paperwork and as you have proof they have it the process will be fast. It is amazing how quick they get you a new one when you throw that at them. If needs be keep asking for the resolutions team, you normally get it resolved before that happens as the managers of whatever departments you have dealt with have to explain the screw ups.

 

I was actually considering fully refunding it just to re-order it again during black friday but I determined the deal I got when I originally ordered mine was actually better than the black friday specials that were going on. But when I told them I wanted to fully refund it they told me I had to wait for it to be shipped back to me, then initiate the refund process which makes no sense. Talk about wasting money on their part when they literally already had my machine in their Texas repair facility. I was also told that because of the repair being performed on my new machine, the period I would be eligible for a full refund would be extended from 21 days from date of invoice (Oct. 30, 2017 is my invoice date in my case) to 45 days from date of invoice (which now puts my full refund date eligibility ending at: December 14, 2017). I asked to have that period extended to 60 to 90 days from date of invoice due to the delays in the repair process and that was utterly and completely ignored by my ****ty point of contact Dell rep. I am worried I won't even receive my machine before the 45 day mark now and worse, before Christmas, nevermind getting adequate time to set it up and test it to my liking/standards to make sure everything is solid. Whatever happens, I DO NOT want to have to re-order it because I will lose out on the good deal I landed it for.

Thank you for your valuable input @GoNz0 I will definitely be pursuing this further based on your suggestions.

 

I got a full refund 2 years and 11 months into my 3 year warranty
This is a failed repair so you can have either a new build or a full refund, you have been without it beyond a reasonable amount of time.

 

I am trying my best to be patient and forgiving here... I know how ****ty it is dealing with big bloated corporations. To give them the benefit of the doubt, they didn't actually receive my machine in their hands until Tuesday afternoon 11-21-17. So starting Wednesday 11-22-17 as day 1 and giving them Thursday and Friday off for Thanksgiving as well as excluding weekends, since their quotes are technically in "business days" that makes Monday 12-11-17 day number 12 officially. But that still doesn't change the fact that I won't be receiving it in time before the 45 day mark when my option for a full refund is currently set to expire. What is your opinion regarding the whole "business day" fact and the holidays that I graciously alotted them "off" in their favor? I would be so screwed if it were my only laptop. Luckily my old HP from 2012 is hanging on still, albeit not rock solid these days.

 

To be fair your 45 days it's on hold when you report the issue. Use that as leverage m8.

Hi everyone,

I bought my 7577 (i7) two weeks ago and am having issues right out of the gate. I've got a bit of light bleeding at the top of the screen by the web cam which is super noticeable on a 15.6" screen. Unfortunately I'm also having an issue with external audio devices plugged into the 3.5mm jack making popping and scratching noises when opening programs or switching through tabs in chrome etc. I've tried my external speakers, apple head phones and my beats by dre and it's happening with all three devices. Is anyone else having this issue? I've called Dell a few times in the last few days but keep getting newbs on the phone that are clearly reading from a script, so support has been basically non existent. I don't want to send it in for repair nor do I want a refurbished model in return. Any tips on how I can get good support in Canada?

Thanks!

 

Have you tried it without the power supply?

 

Nope - I will try though!

 

Same issue here, middle top of the screen, a very bright bleed, which I will not be able to live with. If I press the bezel lightly, it gets less, which means it looks like a construction/screen fixing error. Service desk employee told me this was normal and to be expected, well I disagree. Return to sender.

 

I have the same thing right in the same place, by the way, but it's way less noticeable, I noticed it a couple of times when I was in a dark room and display showed something completely black. Will send a picture later, maybe
UPD: Picture is here. Max brightness, of course. Camera LED for reference

 

Which store did you contact? I,m from Baltics too and waiting when it will be available in our market but I want one with white keyboard so most probably will have to order directly from dell using one of retailers.

 

https://dell.secure.force.com/partner/spf__partnersearch?c=ee&l=en

 

Here is mine for comparison. It's not really noticeable except on an all black screen in a pitch black room, which I really never find myself in that exact scenario except for inspecting the backlight condition in the first place, lol.

 

UPDATE:

Finally got a chance to call Dell today to get to the bottom of my keyboard replacement kerfuffle. They informed me the keyboard is still on backorder and told me they would just issue me a completely new replacement unit at this point. The only catch is that means it's going to be another 2-3 weeks before I see my *NEW* replacement 7577.... So I will be lucky to get it before Christmas basically. Thanks @GoNz0 for the help and tips. My fingers are crossed!

 

They can't expedite it? I got my last 7577 within 3 days of placing the order.
