I have this problem for over a month now. My Toshiba A200 laptop battery is plugged in, but it shows that it’s not charging. I cannot even use my laptop without connecting it to the electrical circuit.
The percentage level is also not moving. It stays in 77%. How can I fix this? This is running under my Windows Vista Home Premium.
In this case, you may want to try uninstalling and re-installing the power management of your Windows Vista.To do this, please follow the steps below:
Open the Device Manager by typing Device Manager on the search box after clicking Start button. This will open the Device Manager window.
Expand Batteries then right-click on Microsoft ACPI-Compliant Control Method Battery, then select Uninstall. (Do not remove the battery while doing this)
Then click the Scan for hardware changes under the Device Manager window or select Action tab then Scan for hardware changes.
Your Windows will scan for any new hardware that doesn’t have software installed.
Restart your computer.
If this doesn’t resolve your problem, try changing your battery pack. Often times, there is a huge chance that your battery will not function properly especially if you always connect it to electrical circuit. Alternatively, try to take out the battery then wait for a few seconds to put it back again. If the battery is new and is still under warranty, ask the store for a replacement. There is a possibility that the battery is defective.
Goodluck!

Hey Hillary,
Normally the DC-DC convertor or power board controls the charge circuit in your laptop. This will control the distribution of power in the laptop and ensure items such as battery charge are working.
You might have something strange such as your power adapter running a little low on voltage, we get units into our workshops quite often that fail to charge batteries correctly and find the power adapter is not supplying sufficient power.
If that's the case its generally a cheap fix, replacing the power board is often a more expensive option.
Ideally you could do with either finding someone with a power adapter you can try or looking for a reputable company that would perhaps give you a free quote – if someone asked us we would happily put one of our adapters on to confirm if its that or not.
I found out that the battery is defective due to over charging. Thanks a lot for the help. You rock!
