Massive Instability Zenbook S 13 OLED (AMD)

Star II

I have the zenbook S 13 OLED (UM5302TA) for almost a year and my laptop had no
problem for around 6-7 months until I started to notice some BSODS on
windows and hard freezes on Linux. From then on my laptop became more
and more unstable to the point where windows wouldn't boot. I also
noticed something odd, my laptop would be relatively stable when plugged
in even if it would rarely crash in any way. I kept digging to find
anwsers for why it would work while plugged in and not on battery power
and couldn't find anything as of yet.

I found that it may have had to do with fTPM stutter
or something like that and disabling it in bios made my laptop way more
stable, windows would now boot and linux would freeze less often however
it was still unstable on battery and mostly stable when plugged in.
Even with tpm disabled it would still be basically unusable on battery
power as a random crash or BSOD would occur at a random time.

In windows i had several kind of BSODs including
IRQL_NOT_LESS_OR_EQUAL being the most frequent), on battery power
windows and linux do not boot on the first try and when i am booted into
windows a BSOD always occurs at a random time showing 3 BSOD screens
next to each other with weird green graphical artefact.

I have no idea why my laptop is this unstable, i have never opened my
laptop, i tried updating bios to v311 (latest) nothing,
downgrading bios to v307 and v304 but it didn't seem to help much.
I also tried reinstalling Windows and Linux while keeping the original
Asus recovy partition but it didn't change anything. After eveything i
have tried i couldn't find anything to make my laptop as stable as it
was when i got it, i can only conclude it is some kind of hadware

Does anyone know something about my issue ? Should i send my laptop back
Asus ? What should i do?



Since we have not tested the Linux system, we cannot guarantee its stability and compatibility with you.
Regarding the operation of the Microsoft system, have you tried to recovery the system before?
If you use the Microsoft system as a single system, updating the system and drivers to the latest version after recoverying the system. Has the situation improved?
Sorry for any inconvenience it may be caused.

Yes i have tried to use the windows alone however it is basically unusable on battery power even with windows on the latest update and asus drivers. I also tried all the asus self tests in bios on the my asus app and they showed no errors and i still have massive instability. Windows does not boot on the first try and BSODs ofthen occur at boot and if i can get into windows as stated before a BSOD always occurs at a random time showing 3 BSOD screens next to each other with weird green graphical artefact. I have tried to use the asus recovery partition before but it doesn't seem to show up in windows recovery even if the partition is here probably because i reinstalled windows. From what i understand the asus recovery partition allows you to reset your pc or run some diagnosis, i doubt it would show anything different from  the other asus self tests. All of that occurs on battery power only with tpm 2.0 disabled as it would make it impossible to boot into windows otherwise which is odd and abnormal as this did not occur the first 6 or so month i had it. I also tried to check for file corruption in windows however it didn't find any kind of system file corruption. I am hesitant trying to send it back to asus for repair ?

I highly doubt this is a software issue at all as i have reinstalled my entire system and all issues still persisted.

If software problems are ruled out, according to what you described, I would suggest you bring back your laptop to our service center for further confirmation.
