So, I finally received my 17 G6 a couple of weeks ago (after 9 weeks waiting for delivery!) and I’ve had a few problems. Mines the Xeon 2286 version with an RTX 3000, and I’ve installed all latest BIOS and firmware updates. Has also had a Samsung 960 Pro and Corsair MP510 disk added. OS is dual boot Ubuntu 18.04 and Debian 10.2.
firstly it always takes more than ten seconds from power on to make it to the BIOS splash screen before even trying to boot. Is this normal? Even my old G3 was nowhere near that bad.
secondly in the boot logs for both OS I get temperature warnings for the Xeon within a couple of mins of boot without loading it at all. That seems worrying.
lastly and most importantly, I get random crashes where the system just resets to a black screen. It becomes unresponsive for maybe 20-30 secs, then caps lock light flashes on and the system can be turned on again with the power button. Recently I’ve found that a particular software compile can repeatedly trigger this if I do a “make -j 16” ie build using all available cores. This is REALLY bad as it means the machine is completely unusable for any serious work.
have any other G6 owners had any similar experiences?

I put my ZBook17 G6 on shelf just in case BIOS update will arrive and mb fix something -- otherwise its useless.
I have 960 Pro as well. Same here -- it thinks something for 8-10 seconds before BIOS splash screen,
no matter what settings you try (fast boot, legacy/uefi -- no visible changes). But this is a minor issue compared
to others that eventually broken down something in firmware.
Most probably thermal interface on your particular CPU was badly applied somehow. I have 2286M Xeon version too
and it behaves pretty well thermally, no crashes no matter 1-thread at max
or 8/16 threads (not sure for 100% about throttling though on all cores). Intended usage was building software too
(C++, JS Webpack, golang).
Pretty sure that reapplying the proper thermal grease and checking that everything aligns tightly (if fans work!)
will fix the issue for you. You don't even need to disassemble too much, but unscrewing and opening middle cover
would probably void the warranty...

Update : I've installed Windows 10 and discovered that windows 10 *also* randomly crashes. This is really hopeless for a top end flagship machine... I've had resets maybe 30+ times now and its not possible to use the machine for any kind of serious work.
Have opened a support case - I would recommend that any potential purchasers stay well clear of the Xeon machine for now as it seems like its a design bug if happening to multiple machines!

Thanks for the info - yeah it could be, I do see lots of short high spikes on the core temps before throttling kicks in and was wondering if that was connected or not as it regularly hits 99 degrees in a second or two. I was wondering if maybe the temp sensor calibration might have been out as the machine seems to sit constantly at (reported) 50-60 degrees under no load, whereas in the BIOS cpu stress test it's reported at around 35 degrees under test...!

RogerAndOut1, I logged a case with HP last night and had a phone call first thing this morning saying that they will send an engineer to come and have a look ASAP - so not resolved yet but seems HP are doing the most they can be expected to do. Probably worth following up on yours in the same way.

Updated info for anyone reading or searching for similar ZBook issues - I've spent quite a lot of time investigating this for HP (where do I send the invoice for a days time & effort?) and Ive installed Windows especially and think I can reproduce this (or at least something similar) reliably....
If you install 3DMarks test suite it seems to be able to stress the machine hard enough to re-produce. You can install it by installing Steam from :
