I bought this laptop in 2010. It recently would not boot upon powering on. Nothing appears on the screen and it repeats a cycle of 8 beeps. I checked the error code manual and it identified 8 beeps as a display problem. I purchased a LCD screen and replaced my old one. I encountered the same problem. I've checked the hard drive and RAM and they both are fine. The only other thing I can think of is something must be wrong on the motherboard.
Any ideas?
