Hello, 2 beeps would indicate a bad RAM slot. If you can (and have multiple RAM), remove 1 and try to restart your PC, then alternate with the other if it still does not work. You may need to change your RAM.
Two other solutions for you:
Remove battery, remove plug and hit the power button for 30 seconds.
Then put back the battery and start your computer
Once you see something on the screen, plug in the cord.
Alternative power drain procedure
Remove the RAM sticks (Clean with a soft lint free cloth while they are out)
