Every time when i restart the system my Time is changing so how can i fix this problem


Hi,

1. There is a coin sized battery present onto your motherboard, which is used to remember your computer CMOS/ BIOS settings as well as date and time.

2. If the system time keeps changing when your computer is turned off and started back, this indicated that your CMOS battery in your motherboard drained out of its charge.

3. Open you computer cabinet and locate the CMOS battery. Replace it with a new one similar to this.

4. Restart your computer and set the time once and it will be retained forever without any problem
I hope this is helpful to you.

Please rate the solution provided.
Thanks
