Thinkpad L13 Gen2 Amd running latest Debian (though it’s not related to OS, had this on Ubuntu as well), the backlight works for a day or so, then stop working. I have to do a power drain / hard reset (hold power button for like a 30 seconds) for it to start working again. I’m wondering if anyone’s come up with a solution to this. Any suggestions are appreciated.
thx mate. my mind went to software because it fixes itself with a hard reset, so that meant for me that software was involved.
