Unlike desktops, laptops use custom parts and cases. You can't put this motherboard and such into another laptop case.
My advice is to extend the warranty or plan for this laptop's eventually end.
What many don't get is we get these machines for a discount. That discount means that some models don't hold up well to daily use of the laptop lid and transport.
There are laptops that are better built but you pay...
I have had my HP dv5t since August 2008. It has an intel Core 2 Duo P8600 2.4GHz Processor and I have 4 gigs of memory installed with integrated Intel 4 Express Graphics and a 250 gig hard drive. Basically, I love my laptop's performance and components, but the build of my laptop is sub par. The keyboard sticks and the hinge for the LCD lid is loose. As a college student I am also not thrilled with it's thickness and bulky design. I have had to send it in for repairs to HP using my warranty because of display interference with the hinge wearing out, but the problem continues to return. Is there any way I can use the components in my laptop now in a new body that won't cause me so much trouble, or is it cheaper to simply buy a new laptop? I have considered sending it in for repairs to HP again, but after 3 "repairs" I have lost faith in their ability to solve the bad design problem.
