Precision 7510 Owner's Thread

The configuration we are looking at has the Nvidia Quadro M2000M w/4GB GDDR5, so does that matter? Using the 7510's screen is not important for us while driving the three external monitors, the lid will be closed.

 

The difference is, if you enable graphics switching in the BIOS, the Intel GPU (built into the CPU) will drive all of the displays and the NVIDIA GPU will be used only for apps that need high GPU power. You would probably be better served to just disable graphics switching so that the NVIDIA GPU will power everything, if the system is going to be docked most of the time. (The benefit to graphics switching is that it allows the GPU to be completely off when it is not needed, saving you power and battery life, and the downside is that it makes your setup a little bit more complex.)

In any case with only three screens in use it shouldn't matter either way.

I'm getting more WD15 docks but probably not until next week. I can test out your scenario when I receive them but you might have already decided what to purchase by then.

 

We are not going to purchase for another 2-3 weeks, so any feedback would be welcome and appreciated! We most likely will not buy any WD15 or TB15 right away since our configuration is hitting the budget, so that is the reasoning behind needing the three external monitors to work on the base laptop (without any docks - for now). Thanks!

 

Wow, what a resource. Great thread. I just ordered my 7510 this morning but I see I have some homework to do tonight to see if I need to cancel and re-order and adjust my configuration before they start processing the order...

One quick question--I have a Dell 90W car charger (this one) and I'm guessing the 90 watts is not going to be enough to drive this machine, but I don't see any other car chargers available from Dell. As I do work quite a bit in a car, keeping things charged up in the car is pretty necessary for me. Will the 90W adapter I have at least run the machine (preferably without throttling the processor) even if it doesn't charge the battery, or am I SOL and have to lug around a big inverter? Or is there another car adapter out there I'm missing that will work with this machine?

[Stop reading here if TL;DR]

FWIW, my config (thanks to my generous boss, who approved it!), if anyone has any emergency suggestions to change anything while I work my way through 110 pages of great discussion here:

• Core i7-6920HQ
• Win 10 Pro
• No Office
• Nvidia Quadro M2000M (need to drive multiple external monitors in addition to internal display; will buy dock separately later)
• EnergyStar 6.1 (it was free, no idea what adding it did, but good for the environment?)
• UHD IGZO display (this was the whole reason for a new machine, as my work requires way more screen real estate than I have now)
• 32GB (16x2, may upgrade later when 16GB RAM sticks get cheaper...in hindsight, maybe I should have gone with 8GB and third-party RAM, oh well)
• 256GB M.2 PCIe NVMe High Performance Class 50 Solid State Drive
• 500GB 2.5 inch SATA 7200 rpm Hard Drive (cheapest available second drive mostly for the cable so I can use my existing 2TB 2.5" drive)
• Wireless card with Bluetooth (I made the mistake a few years ago of accidentally forgetting to tick the box to add the [free at the time] Bluetooth functionality...never again)
• Keyboard with backlight (I miss my backlit keyboard from my first laptop!)
• 6-cell (91Wh) Lithium Ion battery with ExpressCharge (based on discussion earlier in this thread that mentions the Li-Po battery actually doesn't have ExpressCharge--I'm torn on this one, though, but don't see a huge upside to the Li-Po battery--I'm a very heavy battery user, though)
• Win10 recovery on USB (would have come in handy on a couple of previous machines, so why not)
• No fingerprint reader...never felt the need for one

I think that's everything, and I hope I didn't miss anything worth adding. I plan on buying the dock later--they are offering the WD15 dock for $20 off with the machine, but I'm traveling at the moment and it's one more thing to carry with me, and I'm thinking of the other dock (the one the machine sits on top of) anyway--I have an old one for my old Latitude that may work, too. Need to look into that more.

 

For how the machine works with different power adapters, I think Bokeh's M6600 review is a good resource. Scroll down to the section that is labeled "Power Adapters".
http://forum.notebookreview.com/thr...-warning-large-pics-personal-opinions.597919/

It's for the M6600 which is a few generations old at this point, but this power behavior is still pretty much the same. M6600 is also the 17" version, the 15" 7510 uses less power, but the only difference really is in the GPU and a little bit in the display. At 90W you will definitely get throttling.

[Edit] Thoughts on dock. Docks from recent Latitudes/Precisions work with the 7510. Look into getting the WD15 from Amazon or another source, even with the $20 discount you mention it may come out significantly cheaper.
The benefit to the lithium polymer battery is it will supposedly last longer, that is, you will be able to get through more charge cycles before noticing reduced runtime on battery. It is slower to charge, however.

 

Fascinating review. Thanks. He seems to indicate that with Optimus enabled (which is fine, as I don't use external displays in the car and won't be doing anything requiring much GPU work), it actually runs OK on a 90W adapter. Crossing fingers here. Some CPU throttling is OK; I have one Latitude that sometimes throttles to 0.67GHz with one particular iffy adapter, and that's nigh unusable, but killing the GPU and even running the CPU at half speed would be perfectly fine.

Good to know on both. I didn't check much into third-party-seller dock purchases but good to know I'm not throwing away $20 by not buying it now. As for the battery, I did sort of hem and haw about that for a bit, but even though I would probably benefit from the longer cycle-life of the Li-Po battery (especially as this will likely be a long-term machine for me), I've been in a lot of situations recently where charging the battery faster would have been really, really useful (only a limited time near a plug in some airports, etc.).

Edit: made it through all 110 pages of this thread. Great info. Glad I didn't spring for the Xeon. I'm a little less optimistic about the quality of the IGZO display (the one on the XPS15 at the store was beautiful, and I was hoping this was the same display), but we'll see. Now, just waiting for Dell to update my order status...

 

If I run my m6800 on 90w I use ThrottleStop to speed up the CPU which otherwise got throttled down to 400 - 800 Mhz.

 

Keep in mind that display port (version 1.2 or newer) can be daisy chained. So you could run an hdmi monitor from one port and two monitors from a single mini display port if your monitors support daisy chaining.

 

My system arrived yesterday evening... Installed an additional Samsung 850 EVO SSD
Cannot find Dell backup software, is this not included normally?

The screen looks good until now (bright enough)

 

Your best option is to download the ISO from microsoft and use rufus to create a USB install drive. Dell does include a windows 10 reinstall DVD which is ironic considering these systems do not have an optical drive.....
