Acer Aspire 4820TG battery suddenly stopped giving any backup, not even one second. The computer crashes the moment I remove AC adapter and when I turn on the computer again the battery charge level is still what it was before crashing. Very recently the battery used to give 2 hours backup.
Also, in Windows it says 'plugged in, charging' but the battery is slowly discharging, losing around 1% charge everyday. I think this is normal discharge rate for unused battery but I am puzzled why it is not being used to provide backup.
I tried removing battery and adapter and pushing power button for 1 minute. Did not work.
I also updated BIOS from Acer website. Did not work.
