Some days before, my computer turned off suddenly due to "battery failure in UPS" that means UPS battery required to change. I rectified the UPS problem and start the computer. It was required to start on safe mode, then i restart the computer. On that time, i saw the following details on the black screen when the start-up.
CMOS checksum error
Warning: BIOS date&time not set
Warning: Keyboard not found
I entered into CMOS (BIOS) set-up and set the time&date and saved and exit the setup. Now i shutdown the computer properly and restart the computer. Now it worked well.
But i shutdown the computer properly and start the computer after some times (approx after 2/3 hours), the same msg appear on black screen. Again i need to set the BIOS. Everytime i need to set the BIOS when start the computer between long time intervals.
How to solve this problem?
I need the best permanent solution.
