CMOS Battery Low

Hi,

I got this message "CMOS Battery Low" when i started the computer this morning
than it forced me to enter the bios, and i exited, computer started normally than

Is this a problem
Do i have to change the battery i thought they are chargable and charged by the comp.

Thanks

Just replace the battery, at least you know that will fix the problem

AFAIK: The CMOS battery is not rechargable. It is a battery that is similar to a wrist watch battery. Or a battery that you might find in a calculator. Like the TI-83. All it does is provide power to the CMOS to save your settings. If you don't replace the battery, it is possible that you'll have to configure the PC everytime you want to use it. (time, date, devices, etc.)

They are very easy to replace. Just hopefully you don't have to remove too much stuff from the PC to get to it. Use a small flat head screwdriver to remove it and the put a new battery in. Pretty easy.

Thanks for the detailed info

Yes at least just a replacement will fix this, it makes me feel ok
I thought it is ok if i dont change it but if at every reset setting up something would be boring! its not hard to guess

So i ll change it, thank you

ps: i get that message today, how long it will continue you think ? an estimated time ?

Alot of services depend on that battery and it can cause errors when the time/date/HD settings are off set. So go ASAP to the computer store and get the bat. If you need help or instructions on how to install this, just let us know, its not that hard at all.

Well sir, you have asked a good question:

I would guess between four and six weeks, depending uopn your climate............they (batteries) die in cold weather, so if the temperature falls below about 15 Celcius then it could die pretty fast

If you order one today, I am sure that you will be in time

Good luck

Hi,
I bought one just half an hour ago, especially searched for the same made, found and got it
Replaced it with the old one
and it gives the same message at the first start again "CMOS Battery Low"...(!)
With the new battery the time settings were out of date in Bios, i corrected them.
Comp. started

I'm confused
May there be a more complicated problem with the mainboard ?
But its works well, as i'm writing this
nothing unusual

At your first start after replacing the battery.....yes you will have to reset all the information again. But on subsquent starts now that the new battery is in place and the information reset since then....you should be fine and the message should go away.

so you say the message "Battery Low" (it was written like used to be with the old battery) at the first start is normal with the new battery ?
ok than we ll see, i hope so

i wish there wont be a problem with the mainboard

You should not be getting the Battery Low message after you replace it. How old is the computer?

I have some computers that are some 7 years + old and I have not had to replace the battery.

Actually... come to think of it... in all of the hundreds of PCs that I've worked on, I've only had to replace one battery.

its 3 years old
i let it go mate i hope it wont become a bigger problem

thanks for all kindness

It is a pity you dont own a Volt meter.. if the Bat is reading about 3V .. all is well with it.... if lower than 3v. return it to the place of purchase as an enema.. (lol did a google.. and found this.. http://glum.no-ip.org/enema.html )

I am assuming the warning regarding the battery was coming up during POST.. Just check in your Setup.. there may be a setting for that alarm.. particulary the voltage to trigger.. may be set to 3.02V way too high.. 2.7-2.9V should be plenty high.. Just be sure that your looking at the battery alarm not the memory or AGP voltages or you will Fuxor the mobo..or vidcard..

are you sure that you seated the battery on its proper manner?

Try to reinstall the battery on its place...
It seems that you repalce it but you didnt check if the battery is fix on its place, it shouldnt be shaking.
It might be the battery is not inserted properly... try to see again...
