My Laptop comes on but it asks for a password which I don't have.

Hi @likhith ,

Are the 3 beeps actually 1 beep followed by 2 more? {being pedantic I know ;-)}

If so, this indicates a checksum failure.

This could be due to a depleted CMOS battery. (It could also be called a RTC battery (Real Time Clock) or a BIOS battery)

Here’s a link to a video that shows how to replace the CMOS battery in an Acer Aspire 5740DG.

As I couldn’t find a video for your particular model, I hope it is a close enough model number to yours to be of some help. You may have better luck in finding a CMOS battery replacement video or guide for your laptop.
