Dell Latitude E5570

First, I would note that if you get one with a hard drive then you can't have the big battery. The main M.2 SSD bay is a 2280 slot between the HDD bay and the edge of the computer.

1. You can also put a M.2 2242 SATA SSD into the WWAN card slot.
2. The WWAN card slot offers SATA speed. The M.2 2280 slot supports both SATA and PCIe / NVMe (which is much faster than SATA)
3. I have read that the BIOS does not allow booting from the WWAN card slot. A reported work-around is to put the initial boot files on the main SSD / HDD which can point to a Windows installation in the M.2 2242 drive. I have not tried doing this.

Thanks, you saved me a lot of headaches.

Will it be right to say that any m.2 2242 will be compatible in the wwan card slot? Do i need any additional part or bracket to install it?
Any chance that you remember where you read about the workaround?

 

no

m.2 can come in SATA or PCIe, not cross compatible. I believe the E5x70 only supports SATA on m.2 WWAN, not sure

(eg: this card is PCIe m.2 2242. does not support SATA, probably won't work on E5x70 wwan slot)

think majority of the posters have been getting the Transcend MTS400 512GB, since this is the largest capacity offered for this form factor (m.2 2242 sata). PCIe can offer higher speeds, but most people just want more capacity on a secondary device

you dont' need a bracket for the WWAN slot, but you'll need a screw to secure the m.2 card

(have you checked that your model provides a WWAN slot? just in case.....

My E5470 boots fine from WWAN, so no idea why people have issues booting from WWAN on E5470/E5570

Hi there folks, I've a few questions regarding the E5570, I hope it's okay to ask here ...

I'm basically really happy with my machine (i5 quad core, iGPU, FHD, SSD, 6-cell), but I'm getting some noise issues. John (thank you) suggested on another thread that I turn off C-states to try and cure things. I did this in the BIOS, and it's made things quieter, but it's not perfect:

1) In Chrome or Firefox when I scroll up/down on a web page I get a gentle whirring noise coming from under the keyboard.

2) I have an SSD (Dell installed, Samsung PM871 M.2 22); when I do storage intensive activity on the laptop it sounds a bit like a quiet HDD.

I am not mistaking these noises for fan noise, and I'm pretty sure it's not coming out of the speakers.


Are my expectations of silence unrealistic with this laptop?

 

@John Ratsey

I have the 3510 which from what I understand is the same model as the E5570. Are there significant bios differences cause I plan to do significant modifications and upgrades to it. Are any of these changes impossible or not feasible on a 3510.

- 1tb 850evo in the m2 slot
- 512gb transcend in the WWAN slot
- 2400mhz memory

Also going to undervolt and repaste this. I've done this on consumer laptops, but I've never tinkered with a workstation. Just got it cause there was a crazy sale and it was alot cheaper than the E5570. Do the workstations have any special bios or drivers that prevent me from doing any of those things?

 

At one stage my E5570 contained a 1TB Sandisk X400 M.2 2280 + 512GB Transcend M.2 2242. The one glitch was that Windows considered the SSD in the WWAN slot to be removable. I have also read in either this or the E5470 forum that 2400MHz RAM works OK, at least if you have a quad core CPU.

If you look at the 3510's BIOS download page on the Dell support site you should see that it is exactly the same BIOS as the E5470 and E5570 (which might be why the fan rules are sub-optimal). There should be nothing to top you tinkering with the machine but first do a set of measurements with the machine as supplied. Note that to remove the heatsink you first have to remove various components including what Dell calls the "dock frame" which is fixed by nearly 20 screws (see page 24 of the User Manual).

Yea I just read through the entire thing. Seems pretty nice in terms of upgradability. You wouldn't possibly still have yours and have done repaste and undervolting on it? And yea I checked out a few of notebookchecks pictures and there's a ridiculous amount of things to remove before you even get to the heatsink. Either way, thanks man!

 

I've not noticed such noises from my E5570 but, if they are high frequency, then my ears are probably too old to be troubled. Some components can vibrate when changing power states. Overall, i was pleased with my E5570 because the fan noise was less intrusive than on most notebooks.

My E5570 is waiting to be rehomed and I'm currently in a different continent (with my Precision 5510). I was very pleased with the temperatures and fan noise (my E5570 doesn't have the dGPU) so I didn't need to consider taking out all those screws to do a repaste or investigate undervolting. The keyboard layout was the primary reason for my E5570 getting put aside.

hey, thank you john and paper_wastage.

here's a short update on my second e5570 purchase.

3 months ago i had the e5570 with i5-6440hq and amd dGPU and ssd. it had a serious coil whine issue (especially when connected to ac).
so i returned it and bought myself a second e5570 with i5-6300u, ssd and iGPU.

i'm only been using it for a day. everything works great and there's no LOUD coil whine. the system works good but not as snappy as with the i5-6440hq model.

UNFORTUNATELY, THE PANEL i got is lg philips LGDO49B, 156wf6 (dell p/n: F7HH2).
defenitly not as good as the panel i had in the first e5570 (AUO - the panel found in john's e5570 and is mentiond in his review).
it's not as bright (still bright enough), the color coverege is good but not as good as in the samsung panel, and colors seems more saturated.

the biggest issue is that my eyes starts to burn after only a few minutes and the screen appears cloudy. i don't have sensitive eyes as far as i know. when i used the AUO panel i had no trouble working on it all day long without any discomfort.
i have no idea if it's a problem of the backlight or wpm or a blue light thing, but it's really awful.
i tried to decrease the brightness to no good, and tried windows calibration.

https://hardforum.com/threads/led-backlighting-causing-eye-strain-headaches.1528230/
this page causes me extreme eye pain to the point where I either have to look away or close the page after a max of 10 seconds.


anyone knows if there are any tweaks that might be done to improve it?

 

in other words - the panel i got is lg philips LGDO49B, 156wf6 (dell p/n: F7HH2).
this panel strains my eyes and i see everything with a blur and or a cloudy effect
(like i'm staring at something that glows).
i even see like "noodles" in front of my eyes (like when you close your eyes).
it doesn't matter what brightness the screen is - it's still the same. i tried to change the green, red and blue, the contrast, the brightness. i used f.lux to change the color temperature to 6500k. i've scaled the text to look bigger.
i suspect that the problem is the anti-glare coating or the light source.

unfortunately it's always a gamble in terms of what panel you'll get when you buy a new laptop, and there's no way to know for sure what of the e5570 configurations gets the AUO panel (the one i had previously).
can anyone aim me to towards what are the probable causes and solutions, depends on this panel type?
