A few weeks ago, I wanted to upgrade my laptop with RAM.
Unfortunately, the device did not work afterwards and I sent it in. Diagnostics: Mainboard broken.
What can be the reason that the mainboard was destroyed when changing?
Because a laptop is not meant to be upgraded, I think.
Maybe you used the wrong RAM
Grounded before ram change?
Electrostatic charging and touching electronic components can destroy them.
Think yes, you switched off the Lapi and removed the battery before changing.
