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 off 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 (Transcend 240GB SATA III 6Gb/s MTS420S 42 mm M.2 SSD 420S SSD TS240GMTS420S), but it didn’t cause the drain in the beginning.I tried to disconnect the battery so it doesn’t get corrupted until I have fixed the problem, but the laptop is only booting without battery when the ssd is detached, with ssd in the charger apparently doesn’t supply enough power for Laptop to work

February 25, 2019 at 6:54 pm #150612OK
fully discarge and charge the battery measure the battery capacity via batterybar
if you need the pc to work with:
when full, disconnect battery carefully while the pc is still on and plugged in and just let go into sleep mode when not needed.
2 days later turn off, plug the battery into the pc, boot, disconnect power and measure the battery via batterybarreport back

Do you have any guesses what could cause battery drain if it’s not the battery itself? I am a bit hesitant to open the laptop again to disconnect the battery – it has too many screws 🙂 Is there any possible bios setting which would prevent components from draining power in off state?
February 28, 2019 at 1:38 pm #150654If it is off, the battery is just used to keep the cmos and watch out when somebody presses the on button.
The drain is next to nothing, but batteries depending on the quality get drained within weeks or months.
If it drains within a days, the battery is defect (internal short)Need Help?
