I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

good luck. Generally motherboard parts are not repairable. You might find a willing shop to resolder or glue the broken part back.

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

I have just replaced my CMOS/BIOS battery today, as , I have faced some critical problem regarding regular BIOS date/time reset after system shutdown. But I want to know how do i recognize, that my new batter is totally ok or functional.

Battery Meter gadget shows that "battery Not charging"
Is it a gadget problem?

Is there any method available so that I can track that my new installed CMOS battery in PC is working fine?

Please help me.

A:Battery Meter shows CMOS battery not charging

The battery you have replaced is solely there to maintain the clock and other BIOS settings (if you have changed them from their defaults). It will not prevent you from booting your system if it is dead/missing; all it means is that you will have to enter the BIOS each time and make the correct settings and time. This battery is not rechargeable.

Do you still have to enter the correct time, or is the BIOS maintaining this now you've changed the battery?

When I turn it on it says 163 - Time and Date not set - There is no option in bios to set date Non-System disk or disk error replace and strike any key when ready - Bios cannot detect hard drive So the question is if the RTC Battery is weak or dead can it cause above issues Thanks Chris

I am trying to buy a battery for my W500. The problem has been all genuine Lenovo batteries are dated around 2009. Due to shelf life aging, I have had poor luck so far. Can anyone recommend a battery supplier with an inventory of less aged batteries? This battery does not need to be genuine Lenovo. I can deal with the nag screen. I only want a battery that's not more than 2 years old.

I do not see a Cmos battery obviously its there somewhere, If it doesn't look like a large watch battery what else does it look like, I see nothing that can be popped off and replaced.
 

A:Cmos Battery??

Some older motherboards had a barrel shaped, blue backup battery soldered to the motherboard. That was common with 486 systems. In order to replace it, you were required to attach an external battery to a specific connector on the motherboard and set a jumper (maybe) to disable the original battery.
Another possibility is a CMOS ram chip with the battery built into it. Those usually were a large black chip plugged into a socket on the motherboard with "DALLAS SEMICONDUCTOR" printed on it.

Question. In the motherboard manual it says to use a flat screwdriver to pry the cmos battery to change it. Well, I was doing that and the cmos battery sparked. First question is, what tool do you guys recemend. So, the motherboard cmos holder doesn't break, and so it doesn't spark again?
Second, is a spark from a 3v cmos battery harmfull to me, if it came up the screwdriver? I don't even know if it did, but I was a little freaked out by the spark, because it didn't say anything about it possibly happening. Of course, the pc was not plugged into a wall or anything. It, was just the battery itself.

Thanks everyone
 

A:Cmos 3v battery

Probably ran into a residual charge on the power supply.
Want to make sure not to short the 2 battery contacts or
short it to any metal on the case.
You can usually discharge a lot of that by pressing the power
button with the power supply turned off or unplugged.
The battery holder should have metal clips on one side.
Press on the opposite side of the battery to push it against the clips
then lift it out.
The clips are spring loaded to hold it in.

I was having a problem with the computer keeping time while it was shutoff. I installed a new cmos battery and the time is still not keeping when powered off. Any suggestions.
 

Relevancy 58.05%

I recently had a major computer crash following a lightning storm and a lengthy power failure. I feared the worst and called out a tech. It turned out that the CMOS battery was dead and when the power had failed, the CMOS settings were lost.

The tech said that under normal circumstances, as long as the computer was connect to the power supply, the settings were retained but when the power failed, the settings went.

So if I just use system shut down on the computer at night, there is obviously power still getting to the computer. However I assume if if I actually turn off the computer on/off switch then there will be no power getting through and the CMOS battery takes over.

If I do that every time I turn off the compueter I assume that the CMOS battery will not last as long.

Am I correct?

Crack the case open and look for it. THe older ones on 386 and 486 motherboards were some times integrated into the BIOS so you might be out of luck.

Welcome to TechSpot! Hope you'll love this place as much as I do.

If you haven't already done it, then open up your case and look around on the motherboard for a shiny round thing that's about 1.5cm in diameter, pull it out off it's socket and there you go.
It should be near your PCI-ports or near your CMOS-jumper.

I Have an old 166 Pentiun computer with a i430vx mainboard. My problem is that the CMOS battery is dying and from what I could find on the net, it is enclosed in a discontinued Houston Tech HT12888A RTC chip. Some of the info on the internet says that you can open the chip and change the battery though it may be soldered in place and other sources say to replace the motherboard. Also will an add in card containing a clock also power the CMOS. I leave the computer on all the time and it runs fine but when I shut it down and reboot I lose time and have started getting a checksum error/CMOS battery failed message. I have another computer and would like to give this to my son and would hate to scrap a good machine for a $3.00 battery. Any info on this problem would be greatly appriciated.
 

A:CMOS Battery

Well I could understand not wanting to scrap the system due to a battery. There are several options you could look in to. 1. you could purchase a new mother board( for under $100) install it and actually have expansion room for later, or 2. You could scrap the system and keep it to use its parts as test parts or replacement parts for another computer. If it was me that faced this problem I'd look at a new motherboard first maybe you could even find a good used one.

Hi,

Ive been working on this old computer and it had a bad CMOS battery. It was the kind where you put AA's into it and then it plugged into the motherboard. I replaced it, but now the hard drive settings are all screwed up. I went into the Bios Program to set everything. But none of the options matches the hard drive. I know for a fact that this computer worked before the cmos battery went dead. The options in BIOS you can only set to
Type 1, Type2, etc. There is no "USER" setting where you can just put in the numbers of heads/cylinders/sectors. What should i do?
 

A:CMOS battery

If you have no user or auto settings try setting the bios to type one. Hopefully the drive was originally using a drive overlay and will boot ok with this setting.

A:Cmos Battery

Unfortunately there really is no easy repair for this. It would require desoldering the old battery socket and soldering a new one in. While this is not rocket science, it does take great care and some skill to do. A minor slip or laving the soldering iron in place too long can do some real damage to a motherboard. It is best left to a technicial with the proper equipment and skill to do. I would consult your local computer shop about this repair. And it may take a referal to someone else.

Clearing the CMOS will only clear your BIOS settings like Boot order, CPU settings, stuff like that. It will not format anything, nor will it reset any passwords. Even if it is a bios password, most manufacturers make sure that it is a little harder then that to clear the password. If you have forgotten your password for windows it will not effect that but there are ways to do that.

A:is cmos battery getting low

When you open your case you will see the CMOS battery on the motherboard. It resembles a watch battery. It is flat and round and looks almost a like a button. Just pop the battery out and off to Radio Shack or any other place that sells batteries for watches and other electronic devices. The first sign of a faulty CMOS battery is the system clock changing and not displaying or retaining the correct time.

A:cmos battery

Replacing the CMOS battery will probably reset the BIOS settings to their defaults. Unless you or someone else has changed the settings, that will be the same as what you have now.

You could use a camera (or smartphone) with the flash turned off to record the settings. Or, you could just use pencil and paper. (Dell typically provides a fairly limited selection of settings. That's not intended as criticism.)

CMOS battery

What happens and what is the danger to your computer if the CMOS battery dies?
 

A:CMOS battery

The CMOS battery is a very low powered device, just like a little watch battery.

So don't stress, it ain't gonna kill you.

However, its needed to keep data in the CMOS. The CMOS tells the computer what processor is installed (although many computers have jumpers set to tell it this), what drives you have (diskette, hard disk, CD-ROM, and others, and importantly your hard drive's geometry), how much memory is installed, and other important data that your computer needs to know in order to run correctly....

I imagine what would happen if it completely ran out would be that the CMOS would have to be re-written to manually in your BIOS program every time the machine was powered on for anything like normal operating to occur. Certainly you would loose the time settings and would have to redirect the BIOS to redetect the hard drives everytime you powered on.

You can replace a CMOS battery quickly and easily. They are very cheap and just clip out and in to the motherboard. It resembles a small silver disc about the size of a coin.

This is assuming that your computer is not totally ancient (like a 8088, 8086, maybe 286 or something) where the CMOS battery was sometimes not removable. If this is the case then get a new computer you sad man..... Otherwise, it will cost you nothing to replace and if you are not sure of yourself a computer store will do it in about 1 minute.

I need to replace the CMOS battery in this older computer, and need to know the correct one to buy.  The HP website generic instructions and video shows that the battery is a 2032 , but I would like to be certain.  Can anyone tell me exactly which battery I need to buy?  Thanks.

Hi, Yes, they are all the same 3V CR2032 which you can buy from many shops for few dollars. Regards.

It's time to change the battery (first time for a machine I bought in 2004 - not a bad run). I can't get the old one out....any suggestions?
 

A:CMOS Battery

On side should have a metal contact.
You need to carefully pry it toward that contact as it is spring loaded,
then lift from the other side.
Should pop right out.
Be careful you don't want to break the socket.
Some older cmos batteries were soldered on,but I haven't
seen that since around 2000.

hi, i know this is going to sound really stupid but here goes anyhow. i started to change the cmos battery and broke the snap that holds it in place, having no way to clamp the battery in, i superglued it and pushed on it till it dried in place. needless to say, this didn't work and now the battery is superglued in the slot. i guess my question is, can i fix this problem somehow or just pitch it and get a new one?. the pc is an older gateway ps2.

I'm looking for the cmos battery on my old Presario R3240US laptop.  I opened it up today, got all the way done on the back with the heatsink off, but didn't remove the framework.  I also removed the keyboard, but didn't see anything from the top either.  I hate to take it completely apart just for a cmos battery.  It no longer keeps date or time so I know it needs one.  Thanks for the info.

I seem to be having to replace the mobo battery about every 4 weeks....it is a cr3202 lithium..3v... is it or is it not recharged by the psu while the system is on.?.. and if not then something is a drain...somewhat slow...on the battery....I went on a another forum (totalbf2) and got varied responses to that question with no real answers...I believe it is NOT rechargable, and that it should last at least 3-5 years, as the main drain is the cmos clock...so then the mobo is bad i suppose? it is a relatively new ABIT Fatal1ty An8 Sli 939.....

I have not tested that batteries themselves to see if they are dead, I just get black screen lockup...go to Bios and the date is off and fluttering?.. when i reset cmos and replace battery then everything is fine for until the next episode........Help?

You`re quite right, the cmos battery is not rechargable.

I also think you`re right that you have a faulty mobo, no way should it be going through cmos batteries like it is. Have it replaced under the warranty.

Turn off your system and umplug it. Then you can remove the battery to replace it. You can buy a replacemnt at any discount store. Usually just a calculator battery. I thinnd cr2032 is a standard cmos battery but dont quote me on that.
A+ is a good intro to training. It is actually a prerequisite to several other certification programs. I am A+ and had to be to get certified for other things and to work on certain types of equipment and not void the warranty.

If a repair shop told you to replace the motherboard, they must have felt that there was no other options.  Since the computer is so old, it may be difficult to find a motherboard to work with it.  My only other suggestion would be to take it to another repair shop to see what they have to say. Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.

A:cmos battery failed

They are located on the mother board and may look like a watch battery(disk)or like a small AAA battery and while some may be in holders, some older ones were soldered in place. If you feel comfortable doing it, with the power off, open up the computer and look for the battery. If it is in a holder, you should be able to replace it. If it is one that is soldered in place, it may need to be replaced by a professional repair person so as not to damage the MB when soldering in the new one.

Tried to replace my cmos battery with one i bought from Asda ( lithium cr2032 3v)

Maybe i am doing something wrong ;but restarting the pc gave a beeping sound, so i replaced the original battery and the pc started ok except the date and time seemed to have reverted back to the date it was made.

Could this be a battery compatibility (they are both lithium cr2032) ?

pc is a Hp md8070uk media centre which is about 4y old now.

A:cmos battery replacement

Welcome rsinbad to the forums.

Whenever the battery is removed from a motherboard, the bios resets itself to the default time,date and other options. You need to go into your bios and set the date and make sure that all the settings are what you want them to be. Some have an option, after you have set the date and time to setup for maximum performance or you can leave the other settings to their default.

A:Replacing CMOS battery

"If it ain't broke, don't fix it"

The life of the battery will depend on how you use the laptop (or any PC). If the unit sits unused and unplugged for day or weeks at a time (the battery removed from a laptop would be equivalent) then the 3v battery will run down much faster than a PC that is always plugged in and/or the laptop battery is always in and charged.
I have 10 year old PCs here with the original batteries and they are still reading 3v+.

Many laptops use the same 3v battery that desktop motherboards do, but some use a proprietary design. If you can find a "Service Manual" online for your laptop you could find out quickly which you have.

But here is the fast test for your laptop:
Shut it down.
Remove the laptop battery.
Let it sit overnight.
Put the battery back in, turn it on and go into the BIOS settings. If the time is still correct the 3v battery is working. If not, then it is time to replace it.

A:Cmos Battery Not Connecting...

Soldering batteries typically are not a good idea because it requires too much heat to make the solder bond to the battery. And that heat can then damage the battery, or the battery socket. Did you damage the battery socket when you pried out the old battery? While rare (I think twice in 25 years), I have had a bad CMOS battery right out of the new packaging. Have you tried a third or the original battery? Do not touch the new battery with your bare skin as skin oils promote corrosion and attract dust. I put a clean cotton sock over my hand. If re-inserting an old battery, be sure to clean it with the sock first.

Are you selecting "Save" and Exit after you set the date and time?

And most importantly, are you unplugging the computer from the wall and touching bare metal of the case interior to discharge any static in your hand BEFORE reaching into your computer innards and touching anything else?

I don't understand how a heatsink can be "too dirty" to clean. A blast of compressed air is typically all you need. If not enough, a soft brush with a blast of compressed air. And that can be done without removing the heatsink. But if the cooler has been neglected for too long, and it has been caked with dust and dirt along with oily pet hair and dander (cats are the worst) and/or cigarette smoke residues, then you can pull the cooler, remove the fan and dump the heatsink in a sink full of hot soapy water or even run it through the dishwasher. The dishwasher soap may discolor the anodized finish but it will thoroughly clean it without degrading the heatsink's heat transfer efficiency.

Did you ensure you connected the heatsink fan power connector properly?

Hi CollinsMachine and welcome to TSG.

The battery holders are designed so the battery will only fit properly one way around so I think you're ok.

Good Evening All,
Getting ready to change the board battery. Read the "How To" section, but might not be understanding. I went into set up mode to write down the BIOS settings, but not sure what I'm to be writing down. The only thing I see that refers to BIOS is the Core v6.0 and Revision 3.0 5/2002. Is there something I'm missing?
Thanks Much,
Victoria

A:Changing the CMOS battery

There's no need to write down CMOS settings, that's an instruction that used to be necessary long ago.

When the battery is replaced properly, the CMOS defaults (designed to assure system boot) will take over.

Then you boot into the BIOS...set the data and time and save all changes...hit F10 or whatever to save the changes...and you should be good.

I dont understand this. This is the second battery on this MOBO and it is now down to 2.22v. Doesnt it recharge itself? What is causing the voltage drain so radical?
I am I must admit on the system almost 18 hours a day but am not shutting it off and on.
Can anybody shed some light on the situation?
Thanks.

Hi friends

Mine PC is running on a AMD quardracore, Gigabyte GA-MA785GM-US2H, 4 GB DDR III 1600 Mhz Corsair Ram & Power supply along with 8400 GT nvidia . This PC has been OC to 3.2 ghz and is currently working at 3.2 ghz.

Recently I was getting BIOS notification to change the battery as everytime the BIOS had to be reset.

I changed the battery 3 days back but again after a day I again started getting the same notification of changing the battery.

Pls tell where could be the problem.

Regards
 

A:CMOS battery problem

Was the battery you replaced the bad one with brand new? Also make sure it is a 3V battery and to be safe, make sure it has the markings 'CR2032" on it (that is what mine has). Other batteries of the same size and voltage MAY be fine, but I can't really vouch for them. Also, if you have one, it might pay to check the batteries voltage with a multimeter.

Also, if you buy a new one, it might pay to make sure that it is meant for a computers motherboard, as some may or may not be, just to be on the safe side. I don't really know a great deal about these batteries.

Can any one help please? Where will the CMOS/Clock battery be found on a Toshiba Laptop? We have tried all the "hatches" on the bottom and have asked local dealers to no avail. Have replacement battery - but don't know where to put it!

It's under the keyboard, flip the laptop over the screws to release the keyboard are marked with a K for more detail look in the user manual.

I have been advised to replace my CMOS battery. A few questions.

Is the CMOS battery the same thing as the RTC battery?

I understand that some CMOS batteries are soldered in. According to my manual, however, mine does not appear to be soldered in.

What precautions need I take before replacing the battery? Is there possible data loss?

What else should I know?

Thanks a bunch.

Also, where would you recommend purchasing a CMOS battery?
How much can I expect to pay for a compaq laptop about 6 yrs old?
