Laptop won't turn on, blinking caps lock

[bdgsfdg]

I hear the fans whirring, and the power light on the side is on. Display does not turn on. The caps lock's LED is blinking in a 5 long - 3 short pattern.

Please try a hard reset and see if it works.

1. Power off your laptop
2. Remove the a/c adapter, battery and everything that is attached to your laptop.
3. Hold the 'POWER' button down on your laptop for about 10 seconds.
4. Plug in the a/c power supply (without battery) and power on.

Regards.

I am not able to easily remove the battery from the laptop. I removed the a/c adapter, held the power button for 10-ish seconds, plugged the a/c adapter back in, and pressed the power button. The problem still persists.
