N'parlez vous Francais
I'm sorry my French is a little rusty,,,,are you asking about changing time and date on your desktop computer?

Put your mouse cursor on the time, then Right-click on it.
Change the time and date.

If the time and date changes back after you have reset it, then you have a bad CMOS battery. Replace it.
This is a type of watch battery. Generally it is a CR2032.
This flat coin looking CMOS battery is located on the motherboard.

Make sure the computer is off and unplugged from power.
FOLLOW anti-static precautions. (If you do not you will fry out the computer)https://www.youtube.com/watch?v=ao866I9XpTo
Remove the CMOS battery and replace.
If you come back in a Comment, and state the computer manufacturer name,and model number, I should be able to lead you step by step in replacing the CMOS battery.

Hello!
i just want to inform you that CMOS battery failure is not a big deal
you just need to replace CMOS battery from the motherboard
CMOS battery is responsible for date and time management in you PC
also it gives a refrence point in time and space when booting
so if you are a serious programmer you may change it immidiately
and if you are a normal user and you are least bothered with system time and date then
you may keep ignoring this message.

thanks and regards

Hello!

If your having problem with the time setting in your computer, to fix that---is to change/replace your CMOS Battery located inside your system unit. You can buy cmos battery at the computer shop.

Hope I was able to help.

The most possible cause for that is the cmos battery at the mainboard. Open the case and try to locate a round small battery like this

Remove it and using this as a sample buy a new one (it's about 2-5Euros cost). Repalce with the new one and you are ready. After changing the battery a good advice is to get into the bios settings and check them, because sometimes are resetting at default after changing the battery.

In case of a problem or clarification, don't hesitate to post me a reply.
If you are satisfied, rate my solution with the "flags".

Thanks and regards

Hi,

The error means that you have to change the BIOS battery first before trying to change the date and time.
As far as i know with IBM's the CMOS (RTC) battery is located under one of the panels underneath the laptop and is usually covered with red, blue or yellow plastic with wires coming from it. Disconnect the battery and replace it

Once the CMOS battery is replaced you can set the date and time and no more error messages.


Regards.

As if you have tried changing the date & time in your control panel plus BIOS.There is nothing left to be done regarding changing date & time.
But If your CMOS battery in the motherboard fails,it will always goes back to it deafult date & time.Replace the battery and it will solve your problem.

I recommend to use Sony Lithium Battery

The most likely cause is that your bios battery on your motherboard has gone flat.

Normally bios batteries are 3V button batteries. They are relatively generic. I think the battery size number is CR2032.

These batteries are relatively easy to change, if you are familiar with the insides of your PC.

Hello!


That's the 2nd time i hear that kind of problem. Your mboard battery is new, and you did not press "f1" at first start.

so i guess , the cmos time is not change, try go to the bios setup and load "bios setup default." after that change the time setting on the bios. please find time setting and set it with a current ime in your area. after setting press 'F10" to save and exit the setting, the system will restart.

may this help!

Hi,
Please change the Leithium battery fixed inside your fax machine, usually this the problem.
If the Date time is running in different date & time.

Please press Menu, then scrolle left of right arrow key. When you find set Date/Time enter the key mentioned in the Display key and change to your date & time.

After some time see if the date/time working normally. If not change the above mentioned battery.

regards.

Press teh MENU button. Go to INITIAL SETUP. Then to DATE AND TIME
