Compaq Presario 2200 won't hold a charge - on or off AC

Remove the Battery and press power on for 1-2 minutes with out AC power .
Please turn on the laptop with only AC POWER (without battery ). Check it. it may turn on your laptop.

If display ok, then insert battery and use it...

With an extensive use of the notebook,
some times notebook would store some static charges which
indeed will stop the notebook from powering up or charging
the battery. The procedure to remove this static charges from
the notebook is known as power drain. Performing a power
drain procedure will not effect any personal data or delete
any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these
steps:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.

It's time for you to take the computer to a qualified technician, for more "trouble-shooting".

Try this,
Remove battery and ac ADAPTER from the laptop
Press and Hold the power button for 40 sec(No battery and No Power chord)
Connect the battery back to laptop
turn on your computer,
Login to windows
check the battey backup
Connect the Adapter back and check the the battery life

check ur ac supply and then ur battery.if working or nt

Replace the battery.

very first thing u have do is if u have any other laptop try and connect the aac adaptor with that laptop and also try the battery if it is working with the other laptop that means the motherboard of the computer has gone bad u need to replace it and what also u can try is disconnect the ac adaptor and take out the battery from the laptop and the without ac adaptor and the battery press and hold down the power button for one minute and then connect the ac adaptor and put the battery back in and then try and turn on the computer and also what u can do is shut down the computer first and then just hit the power butoon once only to turn it on and then keep tapping f8 key on the keyboard and it will take u to windows advance options and select safe mode with networking and then try if it turns on to the windows screen or not......and if it doesnt turn ono then definately replace the motherboard...good luck....

try a simple power cycle. Take out the battery, leave power adapter plugged in. Hold down the power button for about one minute. Then hit the power button normally this should correct the problem

The problem might be the battery itself. Four years is a long time for rechargeables. Also, check if the error ocurs when the battery is not in the slot.

Problem with the motherboard connector that charge the battery.
