What.s the useful of cmos in this board - Compaq (203966-001) Motherboard

Cmos battery is usually a 3 V button battery, there are variety of different brands so you need to open and check it.

2035, 2032 can be bought from any super market or hardware store. Need to open the PC, locate the battery, which is normally clipped to the mother board. Use a small screw driver and lift out. If battery is soldered to the mother board then need to access under the board and de-solder carefully without damaging the tracks.

It indicates a problem with the system boards. For more info, start here.

Hi, here you can download drivers and a manual:

You can use the autodetect function in seach for your model.

IBM has changed name to lenovo.

The cmos battery look like this:



Here is a youtube video that shows you how:

Hope this will help you.

Here is the solution:

Beeps 9 times:- System not fetching code Microcode

"update" else replace the system board

That deals with your bios.

I would try resetting the CMOS first.

To clear CMOS:

<quote>

Clearing CMOS*
The computer's configuration (CMOS) may occasionally be corrupted. If it is, it is necessary to clear the CMOS
memory using switch SW50.
To clear and reset the configuration, perform the following procedure:
1. Prepare the computer for disassembly.
ã„CAUTION: The power cord must be disconnected from the power source before pushing the Clear CMOS
Button (NOTE: All LEDs on the board should be OFF). Failure to do so may damage the system board
2. Remove the access panel.
3. Press the CMOS button located on the system board and keep it depressed for 5 seconds.
4. Replace the access panel.
5. Turn the computer on and run F10 Computer Setup (Setup-utility) to reconfigure the system.
*When the CMOS button is pushed or the jumper is removed, both the power-on password and the setup password

I would reset the CMOS. This is done by removing that CMOS battery. Also, find the jumper that says "J-21" and move it to the alternative position. The jumper is located on the motherboard. Boot up without that battery in , and choose "Reset" that should clear out the junk. Also, replace the battery. Go to www.intel.com and look for a "bios update" the DG is a value board. a huge value board and one of Intel's bummer boards. Update the firmware. Once you do that, you should be good to go.

Removing the CMOS battery will cause the system to loose all CMOS settings including the password. To do this locate and remove the CMOS battery on the motherboard for five minutes. After this has been done put the battery back into the computer and turn it back on.

make sure that your cmos is set for board if useing board if not on board you will need to go to web site of sound card if cmos is set to be turn off then card will work but not if both are on at same time board and card will not work at same time one or other jim

no there is no cmos battery in hp 1410 printer.neither on the logic board and not on the carriage board. there is no cmos battery in the 1100,1200.1300 and 1400 series.
This will help. Thanks, please keep updated.please do rate the solution positively .thank you for using fixya

Hi Bhauryal,

Just want to now, do you mean you can't find the battery on the board or removing the battery didn't work?

If its the battery, it is usually a round flat coin like shinny thing on the board with a plus sign on it (like the batteries used on some watches), although there are some very old boards that use a different type of battery which looks like capacitors or small drum like things (but these type of batteries are not used on modern board designs anymore). If you really can't find the battery on your board, I suggest you check its documentation, you can try downloaing it from the motherboard's manufacturer website.

If you mean that removing the battery didn't work, it means that your board's CMOS has the capability to hold a charge to save the settings for a longer period of time, if your board has a CMOS reset jumper, I suggest that you use that instead, you will usually find it near the battery or BIOS chip. There are some PC manufacturers (especially branded ones) that implement a different method of BIOS reset so I suggest that you consult the PC manufacturer on how to do it (e.g. for DELL PC's you remove the CMOS jumper, power on the unit for a few seconds, power off, return the CMOS reset jumper again). Hope this helps.

Cheers and best regards,

ok, all you have to do is reset CMOS. the same thing happened to me once I tried to install windows on my supermicro board. What you have to do is load the bootable CD that came with the board and follow the instructions in your book.

What happens is that windows does not have the drivers for the supermicro RAID and SATA components. The board will recognize these on it's own until you go to install windows improperly. Windows does not have the drivers for those, realizes it, and says "Windows has stopped to prevent damage" but it does it anyway. Just clear CMOS, read the book with the board on how to install an OS, and try again.

Clearing CMOS: This can be done by taking out the 3.5v watch battery you see on the board for about 5 minutes. Another and riskier way is to clear CMOS by shorting the pads. On a diagram of your board, you should see CMOS Clear. Find those two pads on you board in that general area from the diagram. You'll know you've found it because the board has CMOS Clear printed near them. Just touch them with a screwdriver for 5-10 seconds. CMOS should be clear and ready to start new.

WARNING! Be careful when clearing CMOS with the pads, if you stick the screwdriver in the wrong place, you could damage your board. Be sure to unplug your power supply before working on your machine (I'm sure you know this.) and be sure to get the correct drivers for windows this time! Oh, and rechange any settings you changed in CMOS since it has been reset to the factory defaults.
