Battery holder replacement

I broke the clip that holds the battery for the CMOS. I've replaced the battery tray, but still get a error regarding the CMOS battery and realtime clock. I've checked the voltage of the battery and also voltage across the connections on the mobo, and all checks out...........what next?

Thanks!

I replaced the board as the solution for this problem. I bought the system board off of eBay for $14.99, when it normally sells for $400.00+. And all is well........

Try to go to BIOS and clear System Event Log. It might help

System battery is low


Dear Anonymous,
BEST PRACTICE: Buy an anti-static wristband before going "under-the-bonnet! Many people will advise that it is ok to delve around the insides of a computer without one, but that can be an expensive mistake...when they only cost a couple of bucks & can save you the trouble & expense of zapping ex$pensive hardware. Your computer box contains extremely sensitive chips & the human body can store up to 50,000 volts of static electricity...
TURN POWER OFF AT WALL SOCKET! [But leave plug in wall socket - this will extend power-system earth to the box.] Then press & hold power-on button on front of box case. (This will "earth" the system.)
Open computer box: Most Dell tower/mini tower boxes have a slider on the back panel: hold slider open & slide side of case backwards.
Find a non-painted - (bare) - metal connection point for wristband alligator clip inside box. Attach clip. {N.B.: if you do this procedure WITHOUT an anti-static wristband, be sure that you "earth" your body, by holding on to the bare metal connection point for a few seconds!} Locate the cmos - (or "BIOS") - battery. It will be a button-shaped battery. Check "Polarity" - (which way up) - of old battery. 'Eject old battery from holder. Check battery TYPE - (make sure that new battery is identical/equivalent. Push new battery into holder. Remove wrist clip. Replace side-cover. Power on. Reboot computer. N.B.: If asked during bootup - restore BIOS settings to "default". That's it! I hope that this solves your problem. Kind regards - 'b'ye - Bruce.

CMOS Battery Clip Holder Broken. The CR2032 battery will not seat properly


It is best to take it to a local computer repair shop. That would be safest. Shouldnt be too expensive to repair.

CMOS Checksum error


Issue:
CMOS Checksum Bad or CMOS Date/Time Not Set

Cause:
This issue is caused when the CMOS values are incorrect. This issue can occur because of any of the below possibilities.
* Bad or old CMOS battery.
* BIOS update.

Workaround 1:
1. Disconnecting power from computer without shutting down computer.
2. Attempt to reboot the computer. If error still occurs after rebooting the computer enter CMOS setup and check all values, this includes verifying the time and date are correct. Once everything has been verified and/or changed make sure you save and exit CMOS setup.
3. If you have a Phoenix BIOS and have an option for 'Reset Configuration Data', set this value to 'Yes' and save and exit the CMOS.
4. If the computer was had the power disconnected while it was still running it is possible this could cause the CMOS to become corrupt. Ensure that the computer is ready to be shut off before turning off the computer. If you have a laptop computer ensure that the battery is charged before disconnecting the power connection.
5. If the CMOS values have become corrupted entering the values in CMOS setup and saving and exiting CMOS should resolve your issues.
Note: If this issue continues to occur after you turn off your computer off it is possible that the CMOS battery may be failing or already bad. Before considering replacing the CMOS battery try leaving your computer on for several days.
Workaround 2:
If you performed workaround 1 and the error occurs again after a complete power down (i..e. removing the power cord), the CMOS battery is likely bad.

Need cmos battery info


CMOS battery is a CR2032 (3V) button-style lithium battery. They are available practically anywhere and are inexpensive. The battery is located near the Southbridge Chipset in a clip-style battery holder. Use a small screwdriver to gently lift the battery out of the holder and replace it with the new one. Do this with the unit powered off, of course

Cmos battery has failed. How do I replace it?


If you remove the cover of your PC you will see a silver circle flat shape, similar to a coin that is the Cmos battery remove it then replace a new battery. Observe the battery holder some holder has small metal attach to the holder you just push the little metal attach to the holder and the battery will loosen up. But be sure to unplug the CPU to the main ac outlet. Or using a small screwdriver to slide back any clips and take out the battery.Note the numbers on the battery and get an identical replacement. You can usually find them cheaper online, but most specialty battery stores will have them as well. Good day and best regards.

Need to replace the clock batteries in my aspire rc 500 can you tell me what to do


You are talking about the CMOS battery. It takes a CR2032 and it can be found on the motherboard. It's about the size of a quarter. Just carefully remove the old one and replace it.
I'm curious to know why you think the battery needs to be replaced. If you clock keeps the wrong time, the battery could be defective, but more likely is the possibility that you computer just can't keep time correctly.
You could try to install a utility like "Atomic Clock" to keep the system updated.

Cmos battery replacement - Gateawy Tower Pentium 2 - what's involved? - any advise gratefully received .


1) Unplug the computer from power.

2) Open the computer case.
(Wish I knew the Model Number, I might be able to give you a link from Gateway Support, on how to open this puppy)

3) Look for the CMOS battery.
The CMOS battery for that computer will be a CR2032.
A type of watch battery, that is approximately the size of a U.S. nickle.

http://www.staples.com/Duracell-DL2032-3.0-Volt-Lithium-Battery/product_273151?cm_mmc=GoogleBase-_-Shopping-_-Technology%3EBatteries-_-273151-DL2032BPK&cid=CSE:GoogleBase:Technology:Batteries:273151:DL2032BPK

There are several different methods of holding the battery, into the battery holder on the motherboard.

I'm not advertising for these guys, but this video tells you about BIOS, CMOS, and shows a typical CMOS battery holder.

For this particular style of CMOS battery holder, there is a spring clip that is released by pushing a tab on the side.
The tab is RIGHT next to the battery.
The tab is pressed to the Outside.
This releases the battery where a fingernail can be used to lift it up, then remove it.

Some CMOS battery holders simply have a spring steel arm, which extends halfway across the battery itself.
The spring steel arm is gently lifted up, and the battery is slid out.

The Positive ( + ) of the battery ALWAYS goes up, when installing.

NOTE*
BEFORE you reach inside your computer, observe Anti-Static Precautions!

Anti-Static Precautions:

Your body carries Static electricity.
Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.
You may not even see it, or feel it.

Computer unplugged from power, computer case open, TOUCH the metal frame of the open computer case.
(Bare metal surface, not painted)

This action will relieve your body of Static.
Should you leave your computer in the middle of working on it, upon your return be SURE to Touch the metal frame again.

How to replace the cmos battery in a systemaxmodel#N241S1


it's the round silver battery right on the motherboard.... unplug the computer first. there is small tab that you move sideways with your fingernail. when that clip is moved far enough the battery will pop out of the holder... to replace the battery put it back into the holder with the round side toward the clip and push down gently... it should snap into place.
