You could permanently damage the system. Why go there?

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.

Here is a link to a CMOS battery that is directly on the motherboard: http://www.laptopparts101.com/wp-content/uploads/2008/12/coin-cmos-battery-560x420.jpg

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!)

The number to contact Toshiba is 1-800-457-7777.

hope this helps you

Assuming you know how to get into your computer and identify the CMOS battery, you just need a pair of tweezers or similar to remove the battery. Once it has removed, take it into a drug store or pharmacy and find the exact same battery, and replace it in the motherboard. If you can't identify the CMOS battery, please let me know and I can help you with that.

hi, if you know how to open a computer or laptop, just remove the cmos battery, it is a round shape silver battery just like the battery for wrist watch but its like 3 or 4 times bigger than the regular wrist watch battery,...just remove the cmos battery then boot up your computer then, after booting up, shutdown your computer then put back again the cmos battery, then boot up again your computer then you can go directly on your cmos, it will not prompt you for any password
