My XPS 9550 is not under warranty since june of this year.
My laptop is running fine until I try to pass 1.9.0+ Bios version.
Version 1.12.0 release few days ago not fix my problem at all.
My issue :
With BIOS version 1.9.0 and more :
When I'm running on battery my laptop crash after few minutes.
On AC with 1.9.0+ bios version it's running smoothly.
With BIOS version 1.8.0 and less :
On AC or Battery, everything is running fine all the time.
So I understand that is the recent BIOS version who is crashed my laptop.
Must I run the 1.8.0 max BIOS version on my laptop ? Because of security patch on CPU, etc. releases since...
Moreover, all driver/firmware are ok and up to date.
Windows 10 was reinstalled 2 times from scratch.
Thank you for your help.
