This is a tall order if you have never done this before, so a word of caution: be careful. No seriously, keep all screws organized and preferably labeled where you removed them from. It helps imensely come reinstallation time.

Two parts. screen assembly disassemble and base disassembly.

*****make sure computer is turned off and battery removed before starting******

Thank you for quick response. As you stated it sounds like a tall tsk to accomplish especially I have never taken apart a laptop. A normal PC you remove a few screws, the covers come off and everything is exposed. I have already purchased the cable and I guess I have nothing to loose to try. I ruin the computer I will be buying a new one which I would do anyway as cost of repair for this issue is over $300.00

Where is it $300 to replace your video cable? And are you sure it is the video cable? In my shop that would be about $75 in labor plus the price of the part, usuallly about $30ish.... Anyways, good luck to you in your repair!

Thanks again for your support and instructions. The cable arrived two days ago. I Followed your instructions and the pictures from the link and I was able to accomplish the task. It took me about three hours to disassemble and reassemble all the necessary computer parts to accomplish the task. I could never have accomplished this task without your help.
