Incorrect battery level (notebook indicator).
by Blackwyche - 11/16/13 1:01 PM
I have one LIFEBOOK S7220. Battery level indicated on LCD display with full charged battery drops to minimum after few minutes. Then, I can use laptop for more than one hour until discharges without problem. I tried this with one new battery and have same results.
When level indicator drops to minimum, If I connect AC adaptor a few seconds, return to full charge indication agan, but drops after few minutes.
If I use laptop without AC adaptor, when battery indicator drops to minimum, if I power off laptop I can't power on because level indicated is too low (nothing appears in LCD display). Then I plug AC adaptor again a few seconds, I remove it and I can power on from battery.
I checked two batteries in other S7220 and worked well. I can't find info about if this is a hardware failure or any type of calibration (bios don't have calibration option).
Somebody know what cause this??
Thanks in advance.
