X22 Battery/Power Management Problem

[denisky]

Last night I tried to see how long my X22 battery would last in a single charge. At 100%, it showed two hours remaining. When it reached 0:00, it wouldn't turn off. Then I kept using it until it turned off after 48 minutes. I was happy that my battery actually lasted for 2 hours and 48 minutes. But I will be happier if the Power Manager shows the accurate battery remaining time.

What am I supposed to do to make the laptop shows the accurate remaining time? Any ideas? Thanks in advance for your help.


FYI, X22 does not support the battery gauge reset.
