    To correct Battery Memory problems, you must completely drain the battery and recharge it. To completely drain your battery, you must go into your Windows Control Panel and select Power. Then you must turn Power Management Off. Next, you must go into your BIOS and make sure that if there is a power management setting there, that you turn it off as well. In most cases, once you are inside the BIOS, you will highlight Power Management and press Enter. Then locate the item Hibernation at Critical Battery, and by using the Minus sign, change the setting to Off. Once these steps have been completed, then use your Escape key to return to the top level menu, and select Save Settings and Exit.

    Once you have completed turning off the power management in both the BIOS and the Operating System, you must unplug the computer, turn the computer on and let it run until it completely runs out of electricity. Then you should charge the battery for 12 hours. At the end of the charging cycle, then run the computer again until the battery is dead, and then charge the battery for 12 more hours. You should repeat this process four times, before returning the computer to its original power management settings.

    Sounds like the battery is dead. Most laptops will not run without a battery. The power supply is good enough for average power consumption but when the hard disc needs to be accessed or a CD spins up, the extra current is drawn from the battery. A duff battery will still hold enough charge to do this while the power supply is plugged in but cannot cope as soon as external power is removed. Best test is to try the battery in a compatible laptop. If your battery is O.K. then I would check out the jack socket for the power supply.
