I have a cheep Chinese Laptop Jumper Ezbook 3L pro.
I am experiencing the problem with battery drain since several weeks - after one day off the battery is half empty.
I think I first encountered this problem after some windows updates but it didn't affect linux - when shutting of from linux the battery remained 100%.
Now the problem persists on both systems and I don't know further. I am plugging off all usb devices when off. I also resetted bios to it's defaults. I've installed a new ssd a while ago, but it didn't cause the drain in the beginning.
Where else can I look for the cause of the problem

  • Are you actually shutting the laptop down from within windows? i.e. going to 'power -> shutdown' and not just closing the lid? – djsmiley2k TMW Feb 21 '19 at 8:11
