How to deal with hp laptop battery plugged in not charging issue

My dad owns a HP dv 2 Laptop which I had purchased from Bangkok. The laptop was working absolutely fine, one fine day suddenly the HP Laptop battery decided it will not charge anymore.

I tried many things, removed my battery many times and connected it again, Windows Vista only showed; ‘Plugged In Not Charging’!

I finally gave up. Thinking the battery maybe have got spoilt. But again after a month I decided to investigate.

HP has given some steps:

This document pertains to HP Notebook PCs with Windows Vista. Understanding battery charging issues If the notebook battery is not charging or the notebook does not indicate that the battery is charging, the most likely scenario is that the battery itself is operating correctly, but its power management software may have become corrupt. In order to correct the problem, you will need to uninstall and reinstall the power management software by using the Device Manager. This document will explain how to uninstall and reinstall the ACPI Battery listings in Windows Vista, as well as how to obtain and install updated BIOS files, if needed to correct other battery issues. Uninstalling and reinstalling power management software in Windows Vista In order to correct problems with the battery’s power management software, follow the steps below.

1. Click Start and type device in the search field, then select Device Manager.

2. Expand the Batteries category.

3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall . WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.

4. On the Device Manager taskbar, click Scan for hardware changes . Alternately, select Action > Scan for hardware changes.

Windows will scan your computer for hardware that doesn’t have drivers installed, and will install the drivers needed to manage your battery’s power. The notebook should now indicate that the battery is charging.

The problem is not in HP actually Window Vista did that for many other brands too.I did what HP said, but it didn’t workout for me. My HP Laptop battery did not charge.

Finally after a lot of research, I did the following:

Run HP live and support on your laptop.
Click on check Battery Health.
See if there is any Genuine fault in your battery.
If its shows OK or good, Goto the HP website.
Click on the driver updates for your HP Laptop.
Check your laptop series, its mentioned under your laptop.
Update your BIOS.
Once your BIOS is updated, Restart your Laptop.
You will now notice that the Laptop Battery has again started charging.
Yes it works! It worked for me!
Allow your battery to completely charge.
Don’t switch on your laptop till the battery charges completely.

Finally your ‘Plugged In, Not Charging’ issue will be over in Vista. I wonder who is at fault HP who cannot handle Vista or Windows who created Vista which don’t allow Laptop’s to handle them.
