I've got a Sony VGN-AR51SU laptop that has been superb until suddenly after trying to take it out of standby I get a black screen, having no other option I held down the power button to reset, now when I try to boot I get 1 long beep followed by 2 short beeps, no screen and nothing else. All keys on the keyboard beep when pressed apart from ctrl / alt / delete.

Can you help??

Hi, thanks for posting the codes, I have opened up the laptop and also followed the blank screen tests as sticky'd on this forum. no matter what I remove and try I get the same error code on every boot. Do you think it is worth buying a new graphics card to try? Or do you have any other tests I could try?

On opening the laptop I have discovered that the SD memory card reader has actually broken away from the motherboard, but I believe this has been broken for quite some time so not likely to be related to the current fault??

Thanks for your help.
