Windows 10: Computer clock falling behind after power outage

    Computer clock falling behind after power outage


    This morning, the power flickered. AGAIN. I got back on the computer and found that the computer's clock had reverted back to the time when the computer was last woken up from sleep (which was 25 minutes before this happened). This often happens when the power goes out and is accompanied with a beeping noise from my computer when the power comes back. This doesn't happen every time the power goes out though.

    1) right click on the time in the right lower corner
    2) left click adjust time and date
    3) select: set time automatically
    4) on the right pane click additional date, time and regional settings
    5) left click on set time and date
    6) left click on internet time tab
    8) left click on change settings
    9) click on update now > ok
    10) open the website time.is
    Time.is - exact time, any time zone
    Compare computer time to time.is

    Consider a new CMOS battery if there are any further problems with time keeping.

    I would suspect the RTC battery as well.

    You don't provide your system specs but I'm guessing you have a desktop machine. If you have a voltmeter then you can measure the voltage of the coin battery that's located somewhere on the motherboard - it should be about 3V.

    Yes, I am indeed using a desktop. This is one of those newer ones where the power supply and everything are all inside the monitor, NOT in a box below my desk.

    All-in-ones usually have a coin battery as well but obviously it's much harder to access.

    Do you see this time skip only after a power outage while your computer was still booted up? That is, if you shut down your computer, pull the plug, wait a few minutes, and plug it back in, do you see the correct time maintained?

    Check to make sure you have the correct time zone selected.
