Windows 7 - System Clock Incorrect after Motherboard & BIOS Battery Replacement

Question

Hello.
for some time I have so that what turns on the computer is the wrong time ...
I think it is the fault of the system because recently I had to replace the motherboard and the new one is the same, I also replaced the batteries from the BIOS, I scanned the computer for viruses ... Any suggestions?

sPeRaCz.PL · Answer

If you are sure about the battery, maybe it is a matter of the time zone in the system? It should be GMT + 01:00

Grzegorz77 · Answer

Is the change constant, e.g. by a multiple of hours? Or rather accidental? What about the date?

Figaro20 · Answer

today, when I turned on the computer, it was yesterday's date, there is no rule as to the hours ...

diseasekowalski · Answer

A colleague checked this time zone as it was advised or not?

Grzegorz77 · Answer

And did you check in bios after turning on, without booting the system?
If you have a meter, check the battery voltage, if OK, check the current consumption from the battery with the board turned off.
Recently, I solved a similar problem by replacing 32.768 kHz quartz

sosarek · Answer

Right-click on the clock in the Taskbar -> Set date / time -> Internet time -> Change settings -> Disable Synchronize with an Internet time server.

Figaro20 · Answer

no, I did not check the time in the bios itself, but I will check, the battery shows 3.38V, as I wrote earlier, it is rather not a record because the previous one was the same, I turned off the synchronization, we will see tomorrow if it did something

Figaro20 · Answer

the time zone is correct, turning off the Internet time did not help,
today, after turning on the computer and in the BIOS and in windows, the date and time are wrong ..
I remember that I also had such a problem on windows xp and the solution was very simple.

Grzegorz77 · Answer

did you check in Bios before starting the system?

Figaro20 · Answer

Exactly...

Deo60 · Answer

You probably have damage to your motherboard, quartz or capacitor. check visually if they are swollen (there may also be capacitors blown up from below and not visible from above).

Figaro20 · Answer

NO I do not know because before it was the same and after the AGP slot burned down I bought a new album .... And by the way, when you write quartz what do you mean?

swiercm · Answer

What kind of power supply do you have in this computer?

Deo60 · Answer

On the motherboard there is a quartz for the frequency generator for the system bus, if it is unstable, the operation time is different from the reality. I met a computer where time was going backwards.

swiercm · Answer

And I have encountered cases where the pseudo-power supply caused, apart from other problems, just indicated by the author. It was a 400W ProComp - very unsuccessful, even for a pseudo-power supply. I suspect that this is it, since the author had to change the motherboard. Author - it would be appropriate to provide the full specification of the PC with the power supply here.

Figaro20 · Answer

ModeCom Feel 3 400W power supply

Figaro20 · Answer

I will add that even when the computer is normally turned on, the time is still changing, but always backward, never forward ...

sPeRaCz.PL · Answer

OMG! Fell ... My friend. Substitute another branded power supply and test.

Figaro20 · Answer

No exaggeration, I will not buy a power supply that is more expensive than the rest of the equipment, besides Feel 3 has no such bad reviews ..

diseasekowalski · Answer

What about the full specs of the computer? What about checking the time in bios BEFORE booting the system?

zbys82 · Answer

Hello I had a similar problem once, a simple replacement of the Bios battery helped. and when did you exchange yours?

kasiunia7777 · Answer

Yesterday I had a laptop with a Chinese crap universal power supply in my hands, on which various voltages were set, it was set a bit too high and the time, the date went crazy. She withdrew as much as she wanted. I switched to the correct voltage and the problem was gone. The fear of using such shit ... but it was not mine :D

Substitute another power supply and see what is happening.

On a working power supply, such things do not happen with the motherboard. If you want to say goodbye and with a new one in some time, please keep working on feel3

Since you are doing it on both motherboards, I give 99% that the power supply is to blame here.

sPeRaCz.PL · Answer

I saw with my own eyes, and actually serviced the computer, which restarted itself once every 2 hours (there were 12 restarts for 24 hours of work). I searched for the reasons for a long time, I prophylactically replaced the Tagan power supply (it was Feel 3) and the problem disappeared after a few days of testing. Nobody ordered to buy another one, only to borrow, for example, from a colleague during the tests. You will find out for yourself about the culprit. That is why I personally suggest a power supply - it has already got you a motherboard once.

swiercm · Answer

Feel 3 is not the last one, but one - it has to be relatively new, two - functional, three - periodically maintained (like any power supply).

The brand itself means nothing if tons of dust accumulate inside and you don't peer into it for years. In such conditions, even branded power supplies crash - the capacitors dry up and the whole thing loses its properties.

Swap the Author at least for the PSU day and we will eliminate him.
Can you give a picture of the nameplate of this Feel 3? I will judge if the lines are strong enough to pull your gear.

Grzegorz77 · Answer

In a PC, the real-time clock has its own quartz, independent of the system clock, moreover, the clock circuit is powered by the battery, and it works even with a disconnected power supply, so its influence on the operation of the clock is rather small. But as an experiment, I suggest you disconnect the power supply and check after some time the clock will change. Check if the CLR cmos jumper is in the right position, and if it is at all

Figaro20 · Answer

I changed the power supply yesterday, while working on the computer on the computer, the clock changed about an hour after the working hour, updated the time and immediately after that at 22.25 I turned off the computer today I turn it on and yesterday's date and time is 22.27 ...

swiercm · Answer

How about the rest of the BIOS settings? Are they saved or are the settings also reverted to the fail-safe state?

diseasekowalski · Answer

Checked before starting the system? Is it already in the system?

Figaro20 · Answer

The other settings are ok. diseasekowalski ... Here and here ....
