\015 So my laptop, which i thought was fixed...now beeps three times when i turn it on. the screen remains black, and nothing happens after the three beeps. the first beep is longer than the second and the third. any ideas?\015

Answers :

Also check your RAM module, reseat or clean the edge connector with soft eraser. Do this when unit is off, unplugged to wall outlet and battery disconnected to it.

Or you can try also to use a good spare ram module to test it.
Most likely video memory.
Try to hook up an external monitor and switch from your LCD screen to the external (Fn key and F7 or whatever key indicates by a little picture that you can go to another monitor.)
Does that work? If so, your video on the motherboard or video card is bad.
