    Laptop battery issue


    I am running LMint 17 Qiana but have no idea that has anything to do with my battery. The battery will show as much as 30 - 50% in the tray and it will simply die. No warning. Nothing.

    Are there some settings I need to make or is this a failing battery?

    Try

    Code:
    acpi -b
    first while on the charger. Wait till it shows full. Unplug the charger. Then run it again a few minutes later and see what it says.

    I have a big battery in mine that is new and I just unplugged it and I get

    Code:
    $ acpi -b
    Battery 0: Discharging, 100%, 06:39:54 remaining

    The battery may be dying. You didn't say how old it is. Batteries start degrading as soon as they are first used, and go downhill from there. All batteries. The percent remaining is a WAG, not even a SWAG, and you can't rely on it.

    Thanks guys for your replies. I did the cli input and it says the same as the tray...92%. I'll do as you suggest and wait until it is 100% then unplug and use for a little while then check again.

    Also, I purchased the laptop 2yrs/4mos ago. Could it be dying?

    Yes, that is old enough for dying.

    Code:
    $ inxi -M

    This one died after 2 & 1/2 years and I bought a over size as a replacement from china via ebay.
