Hello guys.

I recently got a problem with the clock on my pc. It keeps changing and i was searching the internet for a reason. I found out i needed to change the cmos battery so i did that but nothing has helped.

Any of you know why?

yes when moving the jumper the system should be powered off.

What you are doing is, trying to find the correct position and what two pins must be bridged by the plastic jumper on the motherboard so the time and date ect when set in the bios.

Does not keep resetting when the whole system is powered off Wink.

That is problem you have, even though you replaced the bios battery for a new one.
You see the time, date and year need to be set right all of the time because.

As one example when it comes to web browsing you will get a error message of a certificate for set websites being out of date or an error loading the web page it`s self.

But it is the incorrect time. date and year set in the bios of your system that causes the errors...

Your OS looks to the BIOS - so if your BIOS is incorrectly set, there's a conflict.

Ensure the date/time settings are correct in the BIOS, especially after removing/replacing your CMOS battery - it probably defaults to 1/1/XXXX @ 00:00 when you boot.
 
You should be able to right-click on the date and time readout on the lower right corner of your main Windows screen, which will bring up a date and time box. On the main box you can click on change date and time and make the changes. Or you can go to the Internet time tab, click on change settings, and select a source to sync to.

I tried to set the time and date to the exact time we got now and see if it helps.. the time were complete wrong and so was the date
 
If you replaced the cmos battery on the motherboard.
And the correct time and date ect are reset when you turn the system off at the power switch.

It will mean that you have the jumper reset cap that bridges two pins on the motherboard set to flush and set the bios back to factory default board settings each time power is lost to the system.


You will have on your motherboard a set of three pins in a line, where the plastic jumper will bridge two pins at any one time Winkebab.

If it is moved over so it bridges the pin showing to the left or right of the three pins.

Two bridged are for normal operation of the bios, where the other two pins if the jumper is placed as said leave the bios in a constant factory default resetting mode of the bios.

So find the jumper in question on the motherboard with the three sets of pins in a line.
And move it over to the left or right by one pin that is currently shown.

If you look carefully on the motherboard it will say cmos clr near the jumper.

Click on the link bellow to see an example of a bios reset jumper and bridge as you should see on your own motherboard.

The jumper is set to normal operation, in the picture.
Where as moving it over to the pin showing would reset the motherboard back to factory defaults.
Resetting the time and date.

The bridge needs to be set back to the left side to ensure the board keeps the correct time and day there after.

Ty for the reply.. Do i have to turn on pc inbetween when i move the pin jumper?
 
yes when moving the jumper the system should be powered off.

But it is the incorrect time. date and year set in the bios of your system that causes the errors.

So what I was saying was if you set the correct time ect.
It was all fine until you turned the system off, powered it down completely.
Then the time when you next used it was al wrong again, date and year.

Just move the bios jumper pin over, and see if the two pins you then bridge are set for normal bios operation where the time and date should be right.

When you power the system off, completely then power it back on.

You want to know if the bridge link or cap is set on the correct two pins to retain the correct time settings ect.

I just read the manual and looked inside the pc it was set correctly.
 
It was set correctly for clearing the cmos? Or for "normal" operations? For normal operations, you should be able to remove the jumper entirely. I just tape my jumper to the bottom of the case in the event I ever need it.

Are you sure the new battery was good? If you have a multi-meter, I think it should output 3V DC.
