My laptop always smears off after about 30 minutes. The battery or charging cable is not. Does anyone have any tips?
Probably gets so warm that the RAM chips go crazy. Or the CPU.
My thing was last week, that was a bug in the xserver-xorg OpenSorce Displaydriver. "Broken Package". Was easy to fix with Synaptics Packagemanager.
Mint Linux 19.1
What does the temperature of the device say? I'm guessing on dirty fans and dust in front of the cooling fins of the heat sink, so that the heat can't be sufficiently removed (blown out). Always a classic for notebooks. 😉
The result is a shutdown of the device due to overheating.
Because: before the CPU dies the heat death, the emergency shutdown takes effect and the device just goes off.
What can I do there
K i have Windows, that works too
No… But that was not there.
