System freezes when in battery mode

English Hardware
#1

I have a new notebook (HP 250 G7 1B7E3ES) with an Intel I5-1035G1 Processor.
The system works fine as long as there is an power adapter connected.

But as soon as I disconnect the power adapter, and the system is stepping up/down it crashes. If I disconnect the power adapter, and do nearly nothing so that there is no change in load, the system works. I think, this is only in graphical mode. When I switched to runlevel 3 and did some work, the system didn’t crash. But I can investigate oon this a bit further.

Sorry, I’m no expert, so I don’t know which information to provide.

Any ideas?

Many Thanks

Can you give some more details on “it crashes”

  • Can you in that case still go to virtual console one using Ctrl+Alt+F1?
  • If you reboot you can get the previous log using “sudo journalctl -b -2”, likely that will give some clues on the crash. You can share it using https://susepaste.org, for example:
sudo journalctl -b -2 > /tmp/journal.txt
susepaste -n Vanjana -e 151200 /tmp/journal.txt

Try to update BIOS.

Thanks for the help.

“The system crashes” means, it completely freezes. Nothing is possible. No keyboard, no mouse, nothing is working.

I will look for bios updates …

Okay, there is an bios update. but - of course >:( - it is only available for windows systems. Any ideas what to do?

#6

I’ve testet the system in runlevel 3, and the system is working without any problems. No problems, regard the system load.

#7

Okay, the system freezed again, in runlevel 3, after the system was idle for a few minutes …>:(

I think the bootlog on susepaste is clear on what the problem is:

The is repeating many, many times.

This rtw_8821ce is about a Realtek WiFi chip.

Can you remove this WiFi device? If not, can you blacklist the driver, create /etc/modprobe.d/rtl8821ce.conf with in it “blacklist rtw88_8821ce”
