On laptops there isn't an easy way to recover passwords in the BIOS. Sometimes you can reset the password. Other times, you'll have to contact the manufacturer to get it reset.
Some laptops will allow you to reset the BIOS password by pulling the CMOS battery. The CMOS battery is typically located under one of the bottom panels for access to the memory or wireless cards. Some models have the CMOS battery connected by a small wire with a clip connector, others have the CMOS battery placed directly on the motherboard with a metal retainer clip.

On a laptop, if you unplug the power cord, remove the laptop main battery and then remove the CMOS battery - and then wait at least 5 minutes, some models will blank out the BIOS password. Not every BIOS password can be erased by removing the CMOS battery - but if you are comfortable working on the laptop parts it is worth a try.
If removing the CMOS battery doesn't fix the BIOS password, the only option left is to contact the manufacturer for a reset. (If you took your laptop to a certified technician - they would just contact the manufacturer for the reset, and then bill the time to you!)
