Hi Abid
BIOS PASSWORD CMOS/RTC BATTERY The only way to solve this problem is to remember and enter the correct password.
On some laptops, it is possible to delete the BIOS Memory by temporarily disconnecting the CMOS/RTC Battery before reconnecting it and reassembling the laptop.
So no damage
is done during disassembly and the correct component positions and cable
connections are restored during reassembly, this is a job best done by an
experienced repair technician.
See below
for the location of a CMOS Battery in a typical laptop. The CMOS battery is the
rounded, yellow, flattish object at the front centre of the image. While yellow is a common colour, the CMOS/RTC Battery can also be encased in blue, brown, black or green plastic.
On some models the CMOS/RTC Battery is accessible without disassembly, via the Wireless Card compartment underneath the laptop.
On other models, disconnecting and reconnecting the CMOS/RTC Battery is ineffective because nearby capacitors store the data if the Battery is removed and two contact points on the motherboard have to be bridged to dissipate the charge from the capacitors.
The Service/Disassembly Manual for your series of laptops can be downloaded in PDF format from here:

I hope this
helps.
