C-mos batteries run anywhere from $5 to $15. On the Toshiba's they are located either under the main battery or keyboard. It will look like a watch large battery or it will be in a small pouch, generally yellow or green, and have two leads (wires) that go to a small connector.

How do I keep my battery from dying so fast on my laptop?


Would need a few more details, model number, age, how long you've had the laptop. I assume you have adjusted power profiles to maximise battery life

Toshiba satellite pro u400-130 bios password


  • The CMOS is, in basic terms, the part of the motherboard that stores the BIOS settings. To remove the BIOS password from your Toshiba laptop, your best option is to forcibly clear the CMOS.
    To clear the CMOS, you must remove the battery from your laptop and leave it out for at least 30 minutes to an hour. The way to remove the battery from your Toshiba will largely depend on the model. A common way to remove the battery--particularly with newer models--is to release the battery lock on the bottom of the laptop, while sliding the accompanying tab over to the side. This will pop the battery out from its tray so that you can then pull it out all of the way out.
    Before you remove the battery, turn off the laptop and remove the AC adapter. Otherwise, you could end up harming yourself or the laptop components. You must also ground yourself to prevent damaging the laptop with static electricity.
    After about a half an hour or more, return the battery back to its tray and lock it into place. Power on the laptop. The computericon1.png, ideally, should no longer ask you for a BIOS password.
    It's important to keep in mind that resetting the CMOS means that all of your BIOS settings will be reset to factory default. Also, sometimes you may need to leave out the battery for much longer than an hour to reset the password.
  • If resetting the CMOS doesn't work, then your next bet is to try using a backdoor password. A backdoor password is basically a password that manufacturers include with the BIOS so that technicians can access the computersicon1.png that people send in for repair. An example of a Toshiba backdoor password is, unsurprisingly, "Toshiba." When the BIOS prompts you to enter a password, entering "Toshiba" may allow you to access your PC and clear the old BIOS password. Another option is to hold the left "Shift" key down while booting.

Toshiba satelite bios password recovery


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 removable CMOS battery with wires: http://www.laptopparts101.com/wp-content/uploads/2008/12/removable-cmos-battery-560x420.jpg

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.

If you've forgotten your BIOS password, or if someone has changed the password on your Toshiba laptop without your permission, then there are a couple things that you can do to reset the password and access your computer.

Reset the CMOS

· The CMOS is, in basic terms, the part of the motherboard that stores the BIOS settings. To remove the BIOS password from your Toshiba laptop, your best option is to forcibly clear the CMOS.

To clear the CMOS, you must remove the battery from your laptop and leave it out for at least 30 minutes to an hour. The way to remove the battery from your Toshiba will largely depend on the model.

Before you remove the battery, turn off the laptop and remove the AC adapter. Otherwise, you could end up harming yourself or the laptop components. You must also ground yourself to prevent damaging the laptop with static electricity.

After about a half an hour or more, return the battery back to its tray and lock it into place. Power on the laptop. The computer, ideally, should no longer ask you for a BIOS password.

It's important to keep in mind that resetting the CMOS means that all of your BIOS settings will be reset to factory default. Also, sometimes you may need to leave out the battery for much longer than an hour to reset the password

I have a Satellite L45-S7423 Toshiba Laptop the Vista Windows Passwords stopped working. Then after shutting down and powering back up the Bios password is no longer working. The password that I used in...


It's completely possible your CMOS (small BIOS battery) inside the laptop has died. If you are able to disassemble a laptop yourself, go here:

http:www.irisvista.com/tech/

You'll need to remove the CMOS and reassemble.

If not, try to find a friend who can help you download "Hiren's Boot CD" which has tools for resetiing BIOS and other Passwords. Be careful what you do. Study blogs about whatever steps you intend to take and be patient.

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.
Then it not want password.

You need to replace the cmos battery. That's why the time keeps resetting back to 2002.

Post another question on this forum and ask for the service manual for your model. There are techs on here with access to them.

Otherwise you can take your laptop to a local repair shop and they can service it for you. Make sure you don't get overcharged. The batteries are like $5 so total cost should be around $40-$60.
