Sorry cannot help here. You can try this method for troubleshooting dead laptops. This is a very weird problem.

Does it say that all ports are disabled in the BIOS setup menu? Is it an error message in Windows? Didnt install it but now windows is not booting…. It looks like error could be hard drive related. After some research I found this thread on Dell support website.

Okay the LCD screen on my laptop was broken, cracked in the corner after someone closed it with a pen on the keyboard.. I decided to replace the screen myself..

I took it apart got the serial number and ordered the replacement screen. Installed the new screen and nothing shows up except colored portions and lines. Figured it was a defective screen and sent it back for a replacement.

I dont have a problem with my screen and keyboard.. Maybe your new screens are not compatible. What happens if you install the cracked screen back into the laptop? Can you get image on the cracked screen? If your old screen shows image but new screens have only vertical lines, this is some kind of compatibility issue. Make sure your new screen has same resolution as the original one.

Sounds like broken hinges. The only way to fix it is replacing the hinges I guess. What is your laptop model? Did you mean Toshiba Satellite A laptop?

Just to be sure about it, you can access the bios normally F2 or f10 key while restarting by hitting the bios key during Power on Self Test.

If the hard drive is not showing in the list of drives, you probably have either connected the wires wrong or may be your HD is dead. Besides, you can also look for the green light near the keyboard that has the pic of a HD. If that is not lit or not flickering, there is something wrong either with Hd or the way it is connected.

I have a HP Pavilion dv7 laptop, I know that the battery has died in it. My issue is this.

Maybe one of the modules not seated correctly. Try reseating memory modules. Also, test the laptop with only one module installed. Did you try turning it on with the hard drive removed?
