Hello, my laptop loses about 15/20 % of battery capacity during the night... I disabled windows fast start, and also enabled suspend to disk during shutdown... There are no keyboard lights on and it makes no noise... someone know the problem? Is one cell of the battery damaged maybe? Thanks for help
Check the battery wear level, you can do this by using HWMonitor.
Also enter the BIOS (F2) and check the battery health.
