I had the same problem.

I fashioned a small piece of wire, and with each end, shorted the two sides of the battery together, - thereby removing the BIOS settings through a loss of power.

Do this only briefly though - you don't want to drain / destroy the battery altogether, as this will hold your future bios settings in the cmos chip.

Good luck,

Erik.

Replace CMOS Battery on Toshiba L745D


You may be able to reset the bios by shorting out the battery leads for 30 seconds. This may however completely drain or damage the button battery.
The only other way to fix this would be to unsolder the battery and solder a new one back in I've done it before on a dell laptop.

I want to reset BOIS password for Gigabyte GA EP43 motherboard which has no jumper, i try to remove battery but the problem unsolved~


There is a CLR CMOS jumper on that MB next to the SYS FAN 2 connector by the IDE header

open = no clr
jumped= Clear CMOS

From the manual page 32

Use this jumper to clear the CMOS values (e.g. date information and BIOS configurations) and

reset the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the

two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two

pins for a few seconds.

• Always turn off your computer and unplug the power cord from the power outlet before

clearing the CMOS values.

• After clearing the CMOS values and before turning on your computer, be sure to remove

the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.

• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized

Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for

BIOS configurations).

Hi... i have gigabyte ga-945gcm-s2c and i dont know where is the jumper to bios clearing CMOS... please help me to fix this problem... thanks before....


You can get the manual here:
http://download.gigabyte.eu/FileList/Manual/motherboard_manual_ga-945gcm-s2l%28s2c%29_e.pdf

But if you look to the right of the CMOS battery, you will see two pins, to reset the cmos, simply cap the pins with a jumper for 10 secs, or touch them with a screwdriver (mains power OFF of course)

Bios boot password on a Toshiba c655-s5049


When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up

Press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there

also

The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing a battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off the battery power, the BIOS/CMOS settings will be erased.
hope this helps dont forget to vote!

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.

Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.
Removing the CMOS Battery

The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don't attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.

Note: Removing the battery to reset the CMOS will not work for all PC's, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all. IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set. If you reset the BIOS password, but cannot reset the hard drive password, you may not be able to access the drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on the motherboard, and these should be used to reset the system.

Forgot password for bios setting


For this issue if you need to fix it with your self you need to follow the instruction from me. First you need to open your unit. Locate where the CMOS battery located.

The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is.

If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.
• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized
Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for

Clear RTC RAM (CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup to reenter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure!If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMDS, reinstall the battery.

You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P.R) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values
