Precision 7510 Owner's Thread

Tried to swap my LCD panel today. Turns out the 4k screen has a different connector than the FHD screen. I think it's the 40pin versus 30pin.
So next step is to try and replace the cable if that's feasible. Taking the screen out was no big deal, but the cable snakes thru the hinge so it might be a pain.

 

Hi everyone,

I'm looking for a new laptop and 7510 seems to be best suited to my needs. But there's one thing repeating in every detailed review of this computer, that worries me: power usage. They say that 7510 consumes over 25W on idle (Thinkpad or HP only 5-7W) and lasts on battery only about one hour under stress.

Has Dell addressed this issue with some new drivers or bios updates? This seems to be a firmware problem, the competitors laptops are using almost the same parts.

I'm not using my laptop on battery often, but when I do, I want it to last at least 4-5 hours (mostly programming, some web browsing, sometimes movies).

 

You can get power draw well under 10W if you are careful (low brightness, minimum background activity). My 7510 can last 5-6 hours on battery (light load but no particular effort to limit it, and max screen brightness).

Any workstation class machine will last only one hour under stress, they will hit the max battery power draw of about 100W (remember these machines ship with 180W AC adapters)... so a 90-ish Whr battery will have to drain in less than an hour.

 

I'm using Ubuntu 17.04 (dev) and I'm very satisfied of the battery capacity (90 Wh in my 7510).
With common usage like yours, I get at least 8 hours (with TLP power management active). On IDLE (Xeon 1535, 16 Gb, Intel gpu, no wifi, low but readable brightness) I get roughly 4.8 W. Twice with Nvidia (no dynamic switching running Linux). I never missed some power during my work (8 am->5.30 pm), some network usage and mostly PDF projection.

For sure (cf. previous post), when you run Stockfish (8-cores multithreaded chess program) or render a scene using Catia, you can dry your hair behind the two fans and should be on AC. But I do not get any CPU throttling ;-) .

 

That seems to have done it, thanks. I used the tool available here to hide the Intel 530 driver from windows update.

 

I updated to the new 1.9.4 firmware today and it was successful. But, the firmware "device" in device manager still shows version 1.8.3. So, if Microsoft decided to push a new one out through Windows Update again, it looks like there would be no way for Windows Update to tell that the firmware update has been applied already.

 

I have bought a M2 nvme ssd. (I use already a primary SATA ssd.)
Problem : I do not see it in BIOS (system info).

What should I do to see it ?
Is there another trick to install Ubuntu on it ?

Thanks !

 

Aaron44126 & ft_: thanks for your reply. Looks like the reviewed machine was faulty or mis-configured. 25W on idle was way too high...
I won't be rendering scenes or mining bitcoins, so I should be fine with time on battery

(still thinking about 5510 though, but that's a different subject)

 

Nevermind I didn't push the M2 card enough. Not so clear because one can put the screw with misplaced M2 card... I appreciated the nice M2 cover in the 7510, that seems to contain some copper.
To install Ubuntu without any doubt, I disabled all SATA drives and it went straightforward.

 

My idle is usually between 12-14 watts, under load I see it go into the 30's all the time. Unplugged I go about 5hrs with the long life 91Whr battery.
I've got the 6820 cpu and the NVidia M1000M with 2.5" SSD and the 4k screen (apparently the screen is a battery hog).
