Bypass works - wire the USB port to the BMS of the battery or just the USB cable directly and out the headphone port (while removing the port of course).

Well yogas are pretty much as shitty as ideapads. The same keyboard model, no upgradability and the feeling yo want to kill yourself every time you try to use one.

4 years? My laptop is from 2018 (with only the battery in a shitty condition), my mom had a laptop from ~2004 in 2021 (until I embarrassingly fried the motherboard when replacing the hdd). Electronics last forever if you don’t murder them.
