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

And here and here it is no check ...
You have to check in the bios before windows will start. When windows starts to start, there is no need to check it anymore.


BTW recently I had the same symptom in several FSCs - a weak battery.
What did the colleague measure the battery with?
Maybe a colleague will replace it prophylactically? CR2032 should be max 3V and not 3.38.

Besides, I haven't read anywhere what kind of motherboard it is.

And last but not least - does the colleague of the Author have any illegal, non-original or cracked program on the computer? ?

And here and here, I meant that when I turned on the computer, I started the bios there, the time was already bad, then, while firing in the windows, it was also lame
I wrote at the very beginning that I was replacing the batteries.
ASUS p4p800se motherboard

What about the answer to the most important question?

problem solved, if someone needed it, one of the frame bones was to blame.
Greetings.

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

I know the age topic, but it caught me recently. I checked all the software possibilities and it's time for the harware. The battery seems fine - 3.11V (at rest - it is possible that when the computer is working, the clock consumes more current and then the battery actually gives the body, can it be considered good on the basis of this measurement ??).
And if I wanted to measure the current - what value should I expect?

Dell latitude e6520 - bios updated today to the latest version, but also on the previous one for 2 weeks the same thing happened.
win7 ultimate system - freshly installed today.

After shutting down the system and rebooting after some time, the bios shows an hour before shutdown

Time zone good?

3V battery has 3.11V? Perhaps this meter is somehow incompetent?

Moderated By dt1:

The new 3V battery will have a voltage higher than 3V, no wonder, 3.11V is the most appropriate voltage for such a battery.

Zone approx.
since Sunday, from 3:26 pm the clock has completely died ... he has not counted a second on his own. It wasn't until I opened the clock applet that something jolted ..
Batteries "12V" can have, for example, 14V or 11V and that's ok, don't pick on stupid 110mV
I ask again - what current should be drawn from the battery - 10uA, 100uA or maybe nA?
Since the bios settings do not reset automatically, I bet on 32k quartz - am I right?

And I will, however, insist.
Decide whether you are talking about a 3V battery or a 3V battery.
Enter a symbol for this element.

You don't know why a 12V battery can be 14V and you don't know when. I make you aware ;-)

Of course, you installed the 7 Ultimate system original and not a pirate? OEM or OE version? Box?

Try to reset the BIOS by removing the battery

You don't know anything about me, but YOU ASK ME that I don't know why and when the voltage may deviate from the rated value ??
I have given the battery as an example .. It calls for reading comprehension.

However, I followed your advice and replaced the battery and .. I think it works. I will know for sure after returning from work. Only ironically ... this new battery has neither 3.00V nor 3.11V, but 3.33V! Is my multimeter still incomplete?
Ah, and I still haven't found out what current I should expect in the cmos support circuit. ;)

Irrelevant. I will measure how I need it. For now, thank you for your help and I'm leaving the thread.
Have a nice day

The battery voltage is measured after inserting it into the socket on the motherboard.

There is no point in measuring the voltage of a lithium battery without load - a simple red LED is a good test of its condition. The new 3V lithium battery has a standby voltage of well over 3V.

I had a similar problem with the Dell Latitude E6220 laptop - it was the result of a keylogging attack.
blocked clock in bios helped bios reset - disconnecting the internal power supply on the board.
There is an instructional video on YouTube on how to get onboard power on a Dell Latitude E laptop

Due to the fact that it was a keylogger attack - I formatted the entire disk and installed the system
