HP G72-C55DX Power Issues

[dtwroyalty]

My computer stopped actively charging the battery a couple of days ago, it does not seem to readily recognize that external power is connected, however when I do have the power connected, it does not allow the battery to drain or at least that is what the battery indicator shows me.  It was at 40% when it encountered the issue and I have been on my laptop for over an hour with it plugged up and the battery monitor still states that it has 40% remaining.

Can anyone please help me and tell me what is going on with my computer and/or what I need to do!!!

HP Support Assistant software has a battery check, it can check the battery to see if it is bad

That was one of the first things that I tried, however that did not solve the issue.

What did battery check say about the condition of the battery?

[dtwroyalty]

It said the battery was fine, but recommended that i plug in external power. However external power was hooked up.

Try this:

Press and hold power button for 30 seconds

Connect AC only (no battery)

Open Device Manager

Click the plus (+) sign next to Batteries category, right-click all of the "Microsoft ACPI Compliant Control Method Battery" listings, and select Uninstall In the "Confirm Device Uninstall" dialog box, click OK. (it’s ok if you only have 1 of these).

Click the plus (+) sign next to System Devices.

Did not work. When i removed the battery and a/c power and then plugged it back in with a/c power computer would not turn on.

Its one of 2 things

1. Faulty AC adpater

2. Faulty motherboard

How can i tell which one it is?

[Mumbodog]

You will need a known good AC adapter for your model to test, if it does solve the issue then it is most likely needs a motherboard replacement which is expensive, better to buy a new notebook.

Or take it to a reputable repair shop for a professional diagnosis.
