Hi...
I had the same problem...
The solution is only temporary and you will have to reapply it after around 5 to 6 boots cuz it'll just happen again (the beep syndrome).

Just heat up the laptop by turning it on and covering its air vents with your hands.

Then after you hear the beeps turn it off.
Turn the laptop on again and immediately turn it over upside down with the lid closed ofcoarse (simply put it on its back).Hopefully you wont hear the beeps and when you open up the laptop lcd...voila display.

remove and clean your RAM cards. use some contact cleaner with cotton wool to clean it. reinstall and try it.

You've checked the memory board/card, but have you tried using another memory card? The 1 long followed by 2 short beeps indicates that there's a problem with the memory card. Try to remove the memory card, then wipe the gold traces with a dry cloth and put it back in.

If you try replacing the memory card but you get the same problem, then proceed with the video card.

Hi ,

Here are the steps that you can follow to resolve the issue .

Turn the computer off completely ,disconnect any external devices connected to the computer along with the cable for the internet .Then press and hold the power button on the front panel of the computer tower and then hold it for atleast 30 seconds.Turn the computer on and check what happens.

Turn the computer off and then as soon as you turn the computer on tap the f8 key repeatedly until you get a black screen that says advance boot menu options ,select the option that says safe mode and hit the enter key .Select the operating system if you have xp or else you need to wait for the page wherein you can put in the password.If it is sucesful then it will take you to the desktop so you need to restore the computer to an earlier time when the computer was working fine.Click on start?all programs ?accessories?system tools and then system restore .(in case of vista simply type system restore in the search bar and hit enter). Once the resotre page opens up select restore my computer to an earlier time and click next.You will get a calander whic has different dates so select a date when you think that the computer was working fine.The date that you select should be in bold.Click on nest next to exit from the wizard and then the computer will restore and then will restart which wil take you to the normal mode.If the restore is succesful then it will take you to the desktop .

If safe mode does not work try with last known good configuration which takes the computer to the date when the computer was working fine.If non of the options work then you can go to the recovery page to do this instead of the f8 key tap the f11 key until you get the system recovery page then click on next to get to a page that says advance option ,need to click on that and then select system restore .This is for xp in vista its the same key (f11) but you get a recovery manager page then you will have to select advance option then system restore .

If these options does not work then recovery needs to be done wherein the computer needs to be formated.

All the best....
