    Hey guys,

    I need some help. My Asus A8Jm won't turn on unless the charger is plugged in. I haven't used my laptop in a while because I'm home from school and using my desktop. I turned it on today and when I unplug the charger, it shuts off completely and won't turn back on unless I plugin the charger. How do I fix this!?

    Also, sometimes when I turn it on, I get green vertical lines down the screen and all the colors are messed up. I have to turn it off and back on until it goes away. How do I fix this!?

    Thanks.

    Looks like the battery is dead then (from the first paragraph). You could try battery calibration in BIOS, but if it doesn't run at all on battery I don't think that's going to do any good.

    You could check the battery properties using software such as MobileMeter (XP) or RMClock (Vista). See what the max charge reads.

    If the battery is dead, the way to fix it is get a new one...

    For the bad image on power up, that is not good... GPU, LCD, LCD signal cable, one of these things may be going bad. If you're still under warranty (unlikely for an A8Jm) you should get it fixed. Otherwise... I don't know... just wait and see how long it holds? :)

    It works very smoothly...I don't understand how the battery could have died. It was working fine when I came home from college. I'll try what you suggested and see what happens.

    Hmmm...okay so I have Notebook Hardware Control and it says:

    Battery Status: High
    Battery Charge: 100%
    AC Line Status: Online (Charger Plugged In)

    So why doesn't it work when the charger isn't plugged in? Please Help.

    Batteries can die precipitously - good one day, dead the next. Usually a bad cell that does it, or the internal electronics go bad.

    Your symptoms still point to the battery having expired.

    The question is, what does that 100% actually mean, in terms of real charge (mWh or mAh). For that you need RMClock or MobileMeter.

    Oh...okay here's what it says:

    Voltage: 8533 mV
    Capacity: 36377 mWh
    Full Capacity: 36377 mWh
    Wear Level: 29%

    Battery: 0

    Now what?

    Not necessarily. I don't really know what it's going on, since the battery is still not very worn down. Firstly, could you remove the battery and look at the nominal voltage? See if it's larger than:
    Voltage: 8533 mV
    E.g., my batt has 16V (around 16000 mV)

    If so, then that;s the cause of the shutdown and the battery is bad indeed.

    I can think of several other things that you could try, IF the voltage is correct:
    - remove the batt, clean the pins with which it plugs into the motherboard, and plug it back in
    - reset BIOS to defaults, do a BIOS update on the computer
    - try using the battery calibration option in the BIOS, if you have one (although this is not sure to work since it may just shut down when you unplug)
