    hey everyone,
    so i created an account to post here because i found something very odd that happened to my battery...i was using my computer and took it off the charger and noticed out of nowhere that i only had 49 mins remaining so i was searching google like crazy and reading about calibrating it and all that so i figured i was going to do that..well on my way to draining the battery it hit 37% with 21 mins left then i clicked a link on google looked back and the battery is back to 87% with 3:34 left and now its at 86% with 4:37 left...what is going on hahaha it makes no sense...here is my battery info

    Charge Information:
    Charge remaining (mAh): 3558
    Fully charged: No
    Charging: No
    Full charge capacity (mAh): 4166
    Health Information:
    Cycle count: 114
    Condition: Good
    Battery Installed: Yes
    Amperage (mA): -779
    Voltage (mV): 11966

    as you can see my cycle count is very low even though my computer is pushing 2 years old so can anyone figure out what happened???


    thanks so much for everyone:)

    You should have more cycles on your battery after 2 years, but other than that, calibrate your battery properly. The steps for proper calibration are in the following link.

    This should answer most, if not all, of your battery questions:
