Hey everyone, I just wanted to make a recent issue known here.

After the latest BIOS update (I got it 3 days ago, version 1.11.1) my laptop does not boot anymore or is able to wake from suspend - when the laptop is on battery. When it is on a charger everything works.

My investigation lead to the conclusion that it is somehow related to the Intel Microcode that was installed on Dec. 04 (package version is 3.20191115.1ubuntu0.19.10.2). So this microcode worked until I upgraded the BIOS. A workaround is to add the dis_ucode_ldr option to kernel parameter list, which disables the microcode loader.

It is curious that this microcode version worked for two months until the BIOS update so it is definitely something with the BIOS/linux/microcode combination. Windows 10 boot and resume from suspend without issue (as far as I tested).

I will try to downgraed the BIOS to previous version and see where that gets me.
