Each time the computer boots I receive a prompt for the time and date.
Issue
Each time the computer boots I receive a prompt for the time and date.
Cause
- Missing autoexec.bat / config.sys.
- Bad or missing CMOS / RTC battery.
Solution
If your computer has been able to keep the time and date in the past and has suddenly started prompting you for the time and date, and you are running Microsoft Windows 95, Windows 3.x, or MS-DOS, verify that the computer has an autoexec.bat and config.sys file. If this file is missing it will need to be recreated or restored from a backup.
It is common for computers using an Intel 80286 and lower processor to not have a CMOS / RTC battery. If your computer does not have a CMOS / RTC battery, it is functioning as designed.
If you have a computer later than a 80286 or a computer that has been built in the last few years, it is likely that your CMOS or RTC battery has died. Contact your computer or motherboard manufacturer to purchase a replacement battery or if you have a coin cell battery on your motherboard you may also want to find a replacement online or through a local electronics store such as Radio Shack.
