Laptop date and time setting get disturbed automatically when i reboot my laptop

When you boot up and the Date & Time is wrong then you correct the Date & Time, then when you shut down and boot up again the Date and Time has changed. This is an indication that the BIOS battery is flat and you need to replace the BIOS battery. Install a new BIOS battery, go into the BIOS setting and set the Date & Time etc. and the new battery will keep your settings stored in the BIOS.

My Sony Dream Machine won't save the correct time. When I set the date, it defaults back to 2009, and even when I get the correct time set, the clock won't advance. It's been 8:52 PM for...

My wife's unit has the same issue - tried the firmware update (from Sony's website) and their suggested fix with no luck. Still works as a digital picture frame, but wrong date and stuck time kind of disappoint.

FYI - Suggested fix for stuck date/time:

Unplug unit.
Remove backup battery.
Leave for 30 seconds.
Plug back in and then put battery back.
Set date and time.

Didn't work for me, but maybe you'll have better luck.

How to set date & time

To set the Date and Time on your computer - go into the BIOS configuration then to Date and Time to set the correct Date andTime.
If the Date and Time needs setting up again after to boot up the computer again, then the BIOS battery needs replacing because the old battery is flat and cannot maintain (store) the Date and Time.

When i want open a website then we get a problem below the addressbar "Certificate error" mostly Google\orkut\ & also mozila firefox. please give me solution for this problem..


Try checking the Time and Date settings of the computer. Time and Date settings can greatly affect programs that access the internet. Try correcting the Time and Date settings. After correcting it, try browsing some websites where you get certificate errors.

After doing that, restart your computer. If the Time and Date is wrong again, it means that there is a problem with the CMOS battery(complimentary metal oxide semiconductor). This battery saves the basic settings of your computer which includes Time and Date settings, boot up device settings, etc. If that's out of charge, best option is to replace it. Here's an sample image of it. It's just like a watch battery but a bit bigger.

Hope this helps! :D

Every time i turn my laptop on the time and date keep changing and going back nearly 3 years,i have been told it is the CMOS battery is this right?


What you have been told is correct. When the real time clock battery (CMOS) runs out then the date and time will revert back to the day the bios was programed, in your case 3 years ago.

You can set the date and time while you are using Windows but each time you power the laptop down it will loose this information.

A quick workaround is not to power the laptop off but put it to sleep instead until you have got a CMOS battery for the laptop.

How do i change the TIME on my Marquette ECG machine?

setup, time date then type in the correct info. Make sure you use the correct "separator" for the time and date. You need to put in the ":" for time and the "\" for date or whatever your system calls for. If it keeps on loosing time and date settings you will need to replace the quarter sized lithium ion battery that holds this info.

Bios date and time problem

You need to replace the cmos battery in your computer. Theu are usually Cr2032 batteries which you should be able to pick up for about £1.

unplug your computer and open the case.
When you look at the motherboard you should be able to easily locate the cmos battery cliped onto the mobo.
Take the old battery out and insert the new one.
put the case back on and plug the pc into the mains again.
You will need to re-enter the date etc the next time you boot up, but the settings should be retained after that.

Hi there
Take the battery out and start the laptop up on AC power only, set the correct date, time and time zone, shut down the PC and remove the power jack, wait about 30 seconds then power it up on AC only again, If the date and time has changed the the cmos battery has run out and needs replacing. If it keeps date and time the problem is the battery or the powerboard controller that charges the battery is defective. If the battery is getting a charge, run the battery completely out of charge, then try to charge it again.

Good luck and thanks for using Fixya!!
