Question Frequent hibernation (not under windows)

[chyady]

Hi everyone,

I have an old laptop (ASUS VGN-BZ13XN) which I am trying to recycle for a small DIY project in linux.
I have a usb drive with ubuntu-24.04-live-server-amd64 on it, well formatted using Rufus. During install, my laptop regularly went into sleep...
One press on a key and it wakes up again and continues install as if nothing happened.
Once install was done, I am in my command line and I can check out the install, it all seems good, but every once in a while (usually around a minute), it goes back to sleep.

Note: I changed the hardrive with a SSD, I removed the battery to test and I am directly plugged on the wall, I changed the CMOS battery to a new one (and measured 3V correctly), I removed one of the two RAM and switched them, and also tried with an external monitor with lid open/closed, or fully open to check if there was a wiring issue on that side.

Laptop isnt hot (and the hibernation sometimes happened within seconds during install, so i dont think it even had time to be hot enough to be an issue).

Any idea of what could be the cause ?

I only have two options left to try : a new SSD, and a new power supply... but not too sure if that would do anything here.
so if you have any ideas, please let me know !

Thanks in advance

Have you looked at the power settings in the BIOS itself to see if any non-default settings are causing this behavior?

these are my bios settings... nothing weird :/ see here :

i can also see after login that temperature (as per linux) is 41 degrees, doesnt look too high to me.
so before i buy another SSD or power supply, can any of these be the reason or no way it can lead to a looping hibernation ?
or any other ideas ?

(note: i also checked points here, and nothing in my bios about these : https://www.tomshardware.com/reviews/bios-beginners,1126-8.html)

I'd suspect lid switch. It might be broken and making contact randomly and causing going into hibernation.

but can lid switch be triggered when under linux installation steps (which is a sort of "MS-DOS" but for linux) ?
also, i installed linux server, so no graphic, and also this happens as well

Temperature looks okay, if it stays around that. If spiking, you could have a problem.

Have you cleaned the laptop or replaced the CPU's thermal compound on the cooler?

it doesnt even have time to increase after 1min it goes to sleep...
i didnt touch the motherboard/CPU/thermal and really, temperature is stable (it happens very early after boot once i login on ubuntu, then 20sec later, sleep)

As an experiment, try a different distro/OS. Something like Linux Mint.
