Cmos reset cmos

Removing the CMOS battery for 15 mins will reset the CMOS.
The CMOS failure most likely is caused by a flay CMOS battery. replace the CMOS battery will fix this problem.

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.

Hi,

To reset the CMOS the easiest way is, remove the motherboard battery for ten minute then install it again. It will clear the CMOS. Then reset the CMOS/BIOS setup, date/ time etc. Another way to clear CMOS is, reset the CMOS Jumper in motherboard.

To detect your hard drive you can try to check by change the hard drive cables. Change the port in motherboard. Check the BIOS setup and reset it if need.

for that you need to open back cover of laptop .
Then find motherbord there.
Pull CMOS cell from motherbord for 10 minutes then refix it .
Also you can clear cmos with jumper find jumper near cmos cell named "clear CMOS " it has 3 pin
Set jumper i 2-3 position then power up 1 time then again set jumper in 1-2 position then it not ask for password.
Let me know if you need more assistance.
Thanks.

By resetting the CMOS battery all you need to do is to teardown your laptop and have to remove and reinstall the CMOS battery. And for the replacement of the CMOS battery of your Samsung laptop just call SAmsung technical support so that they can give you the exact model of the CMOS battery and where you can have the battery. Thank you.

There might be a jumper on your motherboard that's labelled CMOS, or reset... you just have to move the jumper to the other pin combination, power up your PC, then turn it back off and replace the jumper.
If you can't find a CMOS jumper, try unplugging your computer and removing the battery on your motherboard for a few minutes. When you turn it back on, your CMOS should reset to factory defaults.

You will be able to reset the cmos settings if you can enter the cmos setup during startup.

Take out the CMOS battery for some time and then put it back and restart ur machine.
ur CMOS password has been reset.
