How Can I Reset The Bios Password On The C55-a5302

i usually just remove the battery, the ram cover, then the ram, and underneath this I short out terminals (sometimes covered by a bit of black sticky tape)

On the older ones there was a u-shaped , with a little spot beneath it that needed to be shorted . I usually uase a bent paperclip, to touch each terminal

As I have not opened one of these up.I can only suggest that you look under the ram sticks -look for POSSIBLY TWO SPOTS OF SOLDER AND B500- (it was on the 655 series)

Now this is at your own risk.

If you find these solder dots, and short them for about 30 seonds- then put in a stick of ram, and the power unit, and press the start button- if successful, the laptop will start without password lockout.

If not I suggest that you have a look around -perhaps u-tube, and see what others have tried.

The methods I described, above worked for me, on other models-
