This may work, or there may be a different method for your particular laptop.
Consult the manufacturers web site and download the manual.
DO NOT FORGET TO REMOVE THE NORMAL LAPTOP BATTERY before trying this procedure or it will not work,and you dont want any power going to the motherboard when you work on it.
that didn't work I Tried it for almost 10 times with the power adapter and the laptop battery removed while removing the cmos batter still dosent work I have tried to remove the all the batteries for 1 night but still no luck
