BIOS Supervisor Password Removal

Hi
Bought a laptop cheap from a car boot.
Lenovo L540
It works but fails to boot because no O/S installed on it.
This is when I realised there was an issue.
When I entered the BIOS I noticed supervisor P/W had been set.
This prevents the laptop from booting from internal optical drive or USB.

Is it possible to remove this P/W by software or hardware.

Any help will be appreciated
 
Not sure, but I've seen some password removal tools specifically from Dell.

Are there any jumpers on the motherboard to reset the pwd?

Old topic (I know) unplug power and battery, remove back panels and see if you can see the bios battery (circular flat battery CR232 or equivelant) remove battery for a minute, put battery back in, screw panels on, battery in, power supply in, then try again.

Its the only method is you don't know the current password, adding a BIOS password is as much use as bolting a door from the outside to keep criminal out lol
 
Hirens Boot cd helps with removing bios passwords on many laptops..but usually with Lenovos
you will need to short out a point near the memory and switch on whilst shorting..all lappies
are different though..so you need to google.removing batterys including the internal clock
battery won`t work on a laptop.
