I have the following issue: The laptop discharges during sleep down to 0%. This is below the 5% threshold at which it shuts down automatically when being used. In summary, the laptop drains much energy during sleep at night time.
To understand this, the following was done: 1) powercfg -batteryreport and 2) the admin rights sleepstudy.
1) batteryreport gives:
FULL CHARGE CAPACITY
But, at a 99% charge (indicated by the battery icon in the taskbar), this report indicates more than 100% charge, thus an inconsistency between batteryreport and system battery icon:
2) The second sleepstudy report "correctly" (that is, same as the system icon) specifies the following:
What could be the cause for this inconsistency? Could thes be causing an abnormal shutdown where my laptop thinks it is above 0%, but then drains the battery until the end? Still, this would not answer why it drains so much energy during sleep. However, the latter question could anyway not be solved following so many instructions.
N.B.: Yes, updates all done, Bios latest version etc. ASUS Zenbook UX480FD, 2019 edition, new.
