Unfortunately there is no way to remove it.
CMOS reset don't work since PIII laptops. Bios password is stored on Atmel chip which can't be cleared by resetting CMOS.

Sorry, the desktop methods of removing the battery or using jumpers to reset the BIOS won't work - manufacturers have moved the security to a dedicated chip in laptops, and you either have to contact the manufacturer and provide proof of ownership, or you have to replace the chip (or motherboard).
