Laptop not turning on

My laptop isn't turning on. When i power it on, the led blinks and it beeps infinite times (simultaneously as the led blinks after some time intervals). The ac adopter and battery is fine, i tried removing ram, internal hard disk and even cmos battery as was suggested everywhere on net…but it didn't work. Earlier it worked but now its not workin at all

PS: 1) when i removed hard drive it didn’t beep at all but the power led kept blinking.

2) nothing appears on screen..complete blank.

You said that the computer beeps in a pattern of “time intervals”. That specific pattern is important because it is an indicator of what part needs fixing/replacing. Different broken components trigger different “time intervals” of beep patterns.

Please check Sony’s website for a chart on what the beep codes mean. The link is below:

Does the beep pattern you are getting match any of the patterns on the chart?

Thanks for quick response...

But i don't know if i have an AWARD BIOS or AMI BIOS.. how do i know this?

Btw, yes the beep codes match with those under the head AWARD BIOS and the error it says is memory related... so buy a new ram might help..
