Resetting BIOS for Laptops

By order0917 ·
How do I reset the BIOS of a Toshiba Satellite Pro 425 CDT? My son was the last to use the notebook, and when i tried to use it, after the Memory Test, it prompts for a password. I bought this in the second hand market, all the documentation (e.g.: manual) are not present.

Contact the manufacturer first to see if they will help in getting the bios reset

Password cracking software

The following software can be used to either crack or reset the BIOS on many chipsets. If your PC is locked with a BIOS administrator password that will not allow access to the floppy drive, these utilities may not work. Also, since these utilities do not come from the manufacturer, use them cautiously and at your own risk.

Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.

If memory serves me correctly, Toshiba laptops use a custom loopback plug to reset the BIOS password.

There was a previous Toshiba BIOS question where the peer found a web site that documented the cable.

Laptops are designed to NOT allow any "easy" way to reset the BIOS password.
In part, this is a security feature to make a stolen laptop less valuable.

The correct way to reset the BIOS password is to take the laptop to an authorized service center along with proof of ownership and have the shop reset the password.
