Question about HP dv7t Notebook
My HP dv7t laptop will not shut down properly. When I try to shut it down, the screen just goes black with some of the keyboard lights still on.
I would run a registry cleaning programme first. It may be just looping.

You could have a defective screen - a defective inverter or a CCFL lamp, follow this to determine the fault.
To determine if you have a LCD screen problem, read this and follow the instructions.
Defective CCFL backlight, it may have the following symptom:
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Take out the battery and try running it on the power adaptor alone. If this works, you have a dead battery. If not there's something more serious wrong in the machine.
