SOURCE: removed my CMOS battery, but the BIOS settings won't disable

There are 2 ways you can reset your bios. 
1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete 

2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and
3. Your reset is now complete
There might also be an option within the BIOS to "Load Defaults" if that is all you are looking to do
please see this http://www.11a.nu/software/bios-pc-bios-security-and-maintanance-toolkit/
hope it helps!

Error 0176 ibm


Lots of issues with 0176 error. Could be caused by a dead cmos battery or the system thinks it has been tampered with. I found a couple of clues for you;

The T41 Hardware Maintenance Manual gives the following instructions in case of error 0176:
"Run BIOS setup utility, and save the current settings by pressing F10."
To get into BIOS, you need to press the F1 key when you see the splash screen. I suppost that the splash screen on a T41 will display a ThinkPad or IBM logo, and something similar to "to interrupt normal start procedure, press the blue thinkvantage button".
The idea that a new motherboard might be necessary comes from the T41 Hardware Maintenance Manual. It says that in case the first instruction, i.e. get into BIOS and save current settings, doesn't fix the problem, a new motherboard should be installed.
You could try the following:
Disconnect the AC adapter from the notebook, disconnect all other cables. Remove the battery pack. Press the power button ten times in one-second intervals. Then press the power button again, and hold it pressed down for 30 seconds. Then install the battery pack again, connect the AC adapter. Press the power button.
Re: 0176 Security - The system has been tampered with
The padlock came up after removing the BIOS-battery. It is a security-feature and cannot be bypassed.
Removing the BIOS battery does not remove the supervisor-password but locks the system, if one hat been set to protect the computer from illegal use.
So either try to get the SVP from the previous owner ore replace the board.

My computer dont display any thing . But when i remove smps supply cmos bettery and ram. Then put in each place to run the computer. And gives cmos checksum error. What i do as that.


This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.


During the boot process you will see on the screen a certain key to press to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
You will also need to set the time and date

In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
hope this helps

Forget my password on my hdd I get Hdd password error code [02160]


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 we 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 the Cmos 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 cmos the battery power, the BIOS/CMOS settings will be erased.
for the error
click start control panel administrive tools computer management then select event viewer depending on what operating sytem you have this may vary
in left panel extend the events there you will see errors in red right panel you will no what exactly what the error was and at what time it occured you might be able to work your way through the problem
if you need any further help with this post a reply
hope this helps

Getting a CMOS checksum bad error when starting my Acer M5640 Desktop with Windows 7 Thanks Daniel


Solutions to CMOS Checksum Bad Error

The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.

CMOS Battery may not be functioning properly

If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.

The 161 CMOS error means the CMOS/BIOS battery is dead/flat and needs to be replaced.
The 163 CMOS error means the Date and Time could not be updated when you change the Date and Time setting. This is caused by the flat CMOS/BIOS battery.
When you replace the battery with a new one, the BIOS will go back to the default settings, go into to BIOS setting (press F2 when you boot up) and change the Date and Time, then save and exit.

Checksum error


Hi Oliver, the most common error related to the message,
(Bios Rom Checksum Error). Someone has left a floppy disk in the floppy drive. Once the floppy disk has been removed press the reset button on the PC, your windows will start normally. Next place to look is in your bios.
Open your manual to page 27.
Enter your bios & go to the title Advanced BIOS Features. Check First, Second & Third boot devices they should be as follows. Floppy disk drive, CD-ROM drive & primary hard disk drive. If both of the above are ok than try clearing the cmos/bios by resetting the cmos jumper (JP1) location on page 5. Descriptions of page five on page 6. CMOS settings on page 9.
When your system restarts re-enter your cmos & reset up your bios settings. Lastly if none of the above has fixed the error message, than remove the cmos battery & check its voltage. It should maintain 3volts. If yours' is lower than 3volts replace the cmos battery. There is one other possible fix. It’s an option not given lightly. Flashing a cmos/bios is not recommended unless all other options have failed.

Cmos password for ibm r40


You will have to remember it. IBM puts a security chip on the motherboard, the bios password is burned into this, and there is no way around it. There are a few places that will replace the chip, but they are very expensive. The only other way is to replace the motherboard. I've found that replacing the motherboard is cheaper than having the chip replaced, so, if possible, remember the password.
