HP Omen 2015 BIOS issues?

[bubakovsky]

Hey all!

Thought I'd share my problem with my HP Omen 2015 (15-ax002nc) here and maybe some of you might have a solution for this.

There've always been problems with this laptop like bulging battery and overheating, sometimes random shutdowns, but this one's weirdest of the bunch.

After I turn it on, it takes 8-10 just to boot the BIOS. The screen is off, USB power is off during those 8-10 seconds. It always used to be lightning-fast up until recently.

Not sure if the problem started with this event, but once (two weeks ago maybe) I turned it on and nothing had shown up except for blinking CAPS LOCK in a pattern of 5.3 (long.short) which by HP documentation means "The embedded controller times out waiting for the BIOS.". After I unplugged the AC power and rebooted it, everything went fine.

BIOS settings are saved between boots and I updated BIOS to the latest version F.56 today with no improvements.

Looking at Event Log I've got this error every few minutes or so:

: The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly.

with ACPI source (event ID 13).

Do you have any idea what should I try to fix it (or prevent it from becoming even worse). I hope my laptop won't give up on me, as I've got a master thesis to finish.

Thanks, guys and have a great day.
