Precision 5820 BIOS crash
Originally delivered with Ubuntu. Then reinstalled to company's Win10 and got it killed.
After Windows 10 installation, the desktop gets totally dead,
the only sign of life is the crash output of BIOS startup
what can seen on serial port:

Of course there is no any DELL picture nor other activity on monitor.
We have at office 3 desktops, two of them are dead because of "successful" MS Windows 10 installation.
The third one is still working as it uses Redhat Fedora.
From Linux startup I can see which version of BIOS is on Linux machine:
DMI: Dell Inc. Precision 5820 Tower/0X8DXD, BIOS 1.2.0 11/15/2017
what I guess was the original BIOS version also on those two ones, which are now dead.
I tried some sort of BIOS resurgence (put some bios file to the usb flash, press esc+ctrl and power box) but nothing changed.
Any idea how to revive?

PS: Dell knows about it, but because of lack of motherboards we are on queue only ... (yeh, we bought "next buss day" support ONLY :( )
(1) BIOS Recovery options on a Dell PC or Tablet:

Yes, eventually a tech came onsite and replaced the motherboard. I lost about a month, before that finally happened; fortunately, I was able to switch to another project in the meantime - unfortunately, the impact on my overall productivity was still quite horrendous...

What happens if you reset the workstation NVRAM?
- restart the workstation;
- press CTRL + ESC until the BIOS recovery menu appears;
- select Reset NVRAM.
I cannot believe an operating system can break a workstation so hard; there is a chance, however, it has modified some UEFI firmware environment variable that affect the boot process. Think on UEFI as an excesively convoluted and bug-ridden operating system.

Having exactly same problems here with my Dell Precision 5820. Read this and was about to reach for the phone... Had took out CMOS Batt waited 10 sec holding power and replaced. Same black screen no bios splash. Occasionally it would shut down all on its own after 5 sec. Hard drive boots fine on another identical workstation. So it's hardware/BIOS.
THEN I tried removing CMOS batt and LEAVING IT OUT ON MY MOUSE MAT.
Used Argentum's trick of hold CTRL and repeatedly pressing ESC. Suddenly saw the Windows circling dots (no bios screen) then hey presto, Windows 10 appeared. WITH NO CMOS BATTERY IN THE MACHINE. Windows works fine, un-installed a few programmes. Network is fine.
So I'm now sitting here wondering whether or not I should power down and reseat (or replace??) CMOS battery. Or indeed, just leave the out. Will feedback, but in case this helps anybody else get at least this far.

retyping a second time after Dell page crashed so apologies if a little curt !1) No bios update
2) Had been runing Win 10 for ages without power off just fine
3) got into bios fine (with batt in and not messed with ) to boot from USB - Fedora
4) Half succeeded x2 getting to Gnome splash screen then froze.
5) Went back into bios to enable Legacy boot/rom options
6) Then got blank screen, no POST issues as originally.Would be very interested given my fix above, on advice if Dell would "repair" given it's booting fine via UEFI (with CMOS battery sat on my mouse mat!!). Any advice here very welcome !But it's been a great lesson and tutorial for me about what the fuss regarding UEFI is all about !!1160

Just in case, a test could be to put a brand new, fresh cr2032 battery

How was this resolved? A new motherboard?
