XPS 8930, BIOS 1.1.31 successfully installed

You're brave!  Glad it installed ok for you, and you remembered to change those settings again.

Think I'll wait a few days to see if there are any issues reported when installing this update or afterwards...

@RoHe ,

Brave or stupid, but somebody has to go first.  I knew you would help me out if I ran into issues! 😉

I hope the update goes smoothly for you.

Have a great weekend.

I found this update during my weekly check on the Dell Support website.  I installed it via the Flash Update method.  It did multiple reboots and, at one point, appeared to hang on the Dell logo, but after 15 minutes, it finally completed and booted the computer.

It turned back on UEFI Firmware Capsule Updates and turned off Auto BIOS Recovery and BIOS Integrity Checking.  The capsule updates are now again disabled, and the BIOS settings are enabled.  Be sure to go into the BIOS after the update if you want to prevent Windows Update from messing with your BIOS and want maximum BIOS checking and recovery.

Have a great day.

Regards,

It won't install on mine in Windows. I used to do all the BIOS updates on machines outside of Windows, but two years ago, I had such an update corrupt the BIOS data and the CMOS and I had to send the machine in for a new motherboard. Now, I'm a bit hesitant to try and will wait. If I try inside Windows, I get the BSOD.

I installed BIOS 1.1.31 on my XPS 8930 via the F12 flash update option today, entirely outside of Windows.

No hangs or delays as experienced by @garioch7. PC running fine and Last BIOS time shown on Startup tab in Task Manager seems to be ~1-2 sec faster (~10-11 sec) vs BIOS 1.1.30 (~12-13 sec).

As always, YRMV. So if you're worried, don't update BIOS since 1.1.31 is only a security issue and doesn't change/improve PC performance...

And my shut-down times seem to be faster with BIOS 1.1.31 too...

I have an update on mine. I contacted Dell Support who offered several options, but none were successful. I have recently completed a clean installation of Windows 11 23H2 and suspect that might have something to do with the problem. Running the BIOS update file from Windows results in an immediate BSOD. There are no messages from the program - it goes to the BSOD immediately upon clicking on the file. I attempted to run it from Safe Mode. After making the necessary registry edits and entering NET START MSISERVER in an administrative command prompt, clicking on the file gave me a DRIVER VERSION ERROR. I checked the firmware version in Device Manager and it is 1.1.28, but I can't recall what it was before the clean installation. The current BIOS was 1.1.30. I then tried to reinstall 1.1.30 through Windows, but got the same result as with 1.1.31. This led me to believe that the problem is not the new BIOS, but something that the clean installation has done to the configuration.

Finally, I bit the bullet and attempted the USB installation. The last time I had done this, about two years ago, it bricked the motherboard, but there were a lot of other people complaining about that BIOS version as well and Dell eventually removed it. However, this time it worked, so my concerns were unfounded, but based on history.

I'm still wondering why this wouldn't work in Windows and if anyone has any ideas about that.

@Mike Schmieg  - Probably doesn't have anything to do with the clean OS install you did.  There's probably some bug(s) in the installer that causes it to crash inside Windows. Besides, it's always safer to run BIOS updates entirely outside Windows.  

Did you look in Windows Event Viewer to see if an error was captured when you tried to install the BIOS update inside Windows?   Might tell you why it BSOD'ed. 

Now be sure to make the BIOS settings changes @garioch7 mentioned in his OP, since the update reverted those settings to their defaults...

I installed also 1.1.31    but i recognized that the CPU fan is running high  after 10 minutes, temperature of CPU is 55 degrees , i downgraded to 1.1.30  and fan is quit now.

Has someone seen this behaviour ?

I haven't had this problem with BIOS 1.1.31 after updating from 1.1.30.

Need more details...

How did you install this BIOS update, via SupportAssist, manually inside Windows, via Windows Update, or entirely outside Windows via the F12 Flash Update option?

What CPU and what GPU?

Sure it's the CPU fan and not case or GPU fan?

I downgraded to 11.30 and installed 1.1.31  again via F12 ( before i did via manually inside Windows)  and now after a week no fan problems anymore.

@jaccies  - Glad you got it resolved. Sounds like you had a bad update to 1.1.31 when running it inside Windows.

Always safer to use the F12 menu when updating BIOS.

And every time you install a new BIOS update, be sure to open BIOS setup and disable UEFI Capsule Updates to prevent Windows Update from installing BIOS updates without permission.  And enable these 3 options:

BIOS Recovery from Hard Drive

BIOS Auto-Recovery

Always Perform Integrity Check

I am trying to upgrade BIOS to 1.1.31 using F12. I prepared a flash drive according to the instruction here Dell XPS 8930 System BIOS | Driver Details | Dell US (FAT32 format, not bootable). However, BIOS Flash Update does not see the file or maybe it does not see the flash drive.

Any help is highly appreciated.

@MKadaner  What size is your USB stick? It won't be seen by the F12 Flash Updater if it's larger than 8 GB. A 2 GB USB stick will work. 

You have to plug the USB into PC with power fully off, not a Restart from inside Windows. Then power on and tap F12 to select the flash update option. 

If it still doesn't work, try a different USB stick(again, not larger than 8 GB) and do a fresh download of the BIOS 1.31.0 exe file onto that USB
