Dell XPS 13 7390 not working #124
Comments
What Bios version do you have? |
same problem for XPS 15 6560
|
@moritzschaefer same question as above ;) |
Sorry @mensfeld :) 1.19.2 Resetting BIOS to factory setting didn't help unfortunately. |
Hmmm, then I have no idea :( Worked for me after resetting bios to factory settings though had to reset twice and after had several CPU failures that had to mitigate by blocking C levels in BIOS. |
Just found this post after finally having fixed undervolting on our XPS 15 9570 & 7590 devices. From our research, a BIOS update which "fixes" the below vulnerabilities disabled undervolting on many Dell devices.
As per the above, I believe @moritzschaefer, you could try going back back to 1.18.0. Note, that it is quite unfortunate that you need to roll back your firmware in order to be able to undervolt these devices. Though, the referenced vulnerabilites require physical acccess from an attacker, so it's up what's more important for you. Also, some people have had success downgrading, resetting BIOS and then updating back to most recent, but we did not. Steps that worked for us:
Alternative options: Many people have had success with resetting BIOS via BIOS recovery if they were on the version that disabled undervolting. i.e. if you are on
Hope this helps. |
Thank you @almasen for this small tutorial and even looking for the correct firmware version. A few notes:
Again, thank you, and have a nice day |
It might be a stupid question. How can I downgrade bios on Linux? I tried with
|
@almasen @Maverobot in the end I did not have to downgrade bios for my 7390 - it was sufficient to reset things. |
Thanks. My laptop came out of factory with the newer version bios. I will try resetting it anyway if I cannot find a "cleaner" way to downgrade it. |
Really glad it worked!
That's great! Strangely, we had no success with resetting, but it's always worth trying first |
I am not sure whether it is supposed to work with XPS 13 7390. Here is what I got trying to read the stats:
