Well, from my experiance working with laptops, if it powers on but nothing
comes to the screen, you can try changing the memory, but after that it's
either motherboard, video card (integrated into motherboard), CPU (I
put CPU *WAY* down the list) or heat related.
Assuming motherboard: Motherboard Replacement
Assuming videocard: Motherboard Replacement
Assuming Cooling: Verify fan is spinning properly and clean out heatsink
on CPU
Assuming CPU (Lowest chance): Can you really get a new Laptop CPU that's
worth the price of getting?
Generally it is heat related that causes failure. Check the caps on
motherboard, resolder new ones if that's the problem, other than that it's
always motherboard replacement.
