Chosen Solution

Hi, I was given an Asus K52F laptop which had a BIOS lock which I still have been unable to remove. Whilst trying to fix that issue, I created another one. Typical! Whenever I press the power button, the Power indicator, Caps lock and Num lock LEDs all come on for about 3 seconds and then go off again and only 20mA is drawn from my PSU. At first I thought this might be some sort of blink code but have decided against that. Any help is appreciated :).

Remove the battery and unplugge the charger too. Now press power button for 60 seconds. Now plug in the charger without battery power on the laptop. Now reinstall the battery it will work.
