Re: HP Pavilion dm4 - Plugged In, Not Charging - Tried Everything

Go to google, search Download HP Power Manager Windows 8, make sure you are downloading from an official HP site and install it after download.

I found this link:  https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=Z7550-63114

Click on the "Receive for free" button and then fill out all the information and then go through HP's song and dance routine until you see the "Get Software" link and there ya go!

Quoting the following link:
