3 long beeps normally indicate defective memory or loose memory on DIMM so take out and insert it again or you need to replace with new memory module. Where as fast beeping indicates Graphics error and need to change the graphic card

If this dont fix please tell me
Best Luck!

The nuimber of beeps and duration is a code as to what is wrong. Usually beeps inidicate a hardware malfunction like bad or mismatched memory, or CPU or something cam loose inside like a IDE cable, take not on how many beeps and the sequence, and please post back.

Hope this helps.

3 Short beep and 1 long beep and blank screen. My


That means there is s problem with the RAM on the motherboard (Problem lies with the Memory Chip). This could be a result of a Memory chip that has not been inserted properly or it has moved away from its contacts on the motherboard. This will be fixed by opening up the RAM compartment and remove the memory chips and replace them back carefully. Try to switch on your laptop again. Make sure that when you are doing all this, the computer is off and the charger is not connected to it. This I hope will solve your problem.

1 LONG BEEP 2 SHORT BEEPS


Does anything ever post to the screen when you press the power button? if not, it's your video card. The links below are for 1 long and 2 short and they say it's the video card. I've heard that Sony extended the warranty on some models so you might want to go to their website and check yours or in a google search type: Sony GPU Extended Warranty. I did and I see they extended it from one to three years. They have the faulty Nvidia Graphics Card which was a major problem for many manufacturers.

It looks like issue with either mother board or processor.
open the box and remove all memey and power it on. if it makes a beep sound, there is no issue with processor, else we suscpect processor. If it make beep sound, it might be mother board issue. And for checking monitor working condition, remove monitor data cable and see no cable connected messages comes in monitor or not
