Precision 7510 Owner's Thread

There's a thread for it:
http://forum.notebookreview.com/thr...pre-release-discussion-5520-7520-7720.800132/

 

I've got a stupid question. I share it anyway :
is it possible to boot a M2 NVMe SSD Samsung 960 pro drive in SATA mode ?
(The NVMe power management is coming in Linux -- search "Lutomirski lkml" -- but is not still here, and my 7510's power usage is much higher than before installing this M2 NVMe... so if I can wait even with lower performance, I'll run into this hack.)

 

Nope... An M.2 drive is either NVMe or SATA as a characteristic of its design. You can purchase a SATA M.2 drive and install it in that slot and it will work, but you cannot transform a NVMe drive into a SATA drive.

 

I think there is a bug in battery charging with 1.9.4/1.9.5 BIOS (cf. one of the recent messages of this thread).
E.g. running a Gnome terminal :

upower -d

Some few second before, I charged my battery (with laptop shut down) and upower showed me "energy: 90.9948". I've lost 28 Wh in 10 seconds !
When I charge (laptop off), it *seems* to me to be recent (>= 1.9.4 BIOS ?) that the battery LED is blinking during charging.

Running Windows 7, powercfg's energy report show me roughly the same thing, meaning 63 Wh with complete charge.

In BIOS, I had choosen 'Adaptative' and today 'Standard' battery charge, same behaviour.

You guys, could you please investigate on your 7510s ? Thank you !

 

Worn out battery?

 

That's what I thought but BIOS is reporting battery's shape as 'excellent', as Dell's W7 tools.

 

My battery wear level is 10.2% (according to HWiNFO64, after 9 months), but of course BIOS and Dell's tool shows it as "excellent".

 

Dell is sending me another battery. That's a very good point, I did not have to argue.
That's does not explain why I get only 70 % of theorical capacity after 10 months only. I still think that there is a link with BIOSes 1.9.x.

 

Hello Aaron, I was glad to see your posts about replacing your display. Can you let me know what supplier you used to buy your replacement panel. I've just bought a refurbished 7510 with a non IPS panel, and want to swap it out as soon as I can. I'm looking for a European supplier of quality panels, its very hard to choose who to go with on Ebay.

 

Yeah, I never had good success, I bought two panels online and didn't like either of them. The second one came from eBay and seemed great except I discovered a stuck pixel that only showed up under certain circumstances. I ended up swapping the panel for another 7510 IPS panel from Dell, with a coworker who cared less about the screen.
