Resetting the "Power On" password

Hi.
Power off laptop. Disconnect mains pack. Remove battery pack. Wait 30 sec. Connect just mains adaptor. Press power on button. press f10 for bios settings. Your passwords are now cleared

To reset the password you need to know the previous password which you obviously dont or you wouldnt be asking.two ways around this safest/easiest way get a program called spotmau.once installed on a boot disk it can reset all password fields.the other way is to remove the rtc battery located on the circuit board and replace after a minute or so thus resettinng bios;though this way requires a partial strip down.your rtc battery may be in between the mem slots(it is on the 5110)so this would in that case be simple.just unscrew retaining screw of mem cover and pop out the battery,replace it and boot up.(it looks like a large digatal watch battery)
