The CMOS (BIOS) battery keeps the computer'a comfiguration and the Date & Time settings in the CMOS (BIOS) chip in its memory. When the CMOS (BIOS) battery is flat these configuration information is lost. Replace the CMOS battery with a new one, in most cases this battery is a lithium 3 volt battery type CR2032 and it is coin size battery 18mm in dia.(check it to make sure the type of battery is installed on your motherboard). When you replace this battery then go into the BIOS and set the Date & Time etc.
There are two reasons for this issue
1. It is battery - but you have replaced it.
2. It could be your BIOS is degraded try the following steps
a. Reset your settings to defaults by using the jumper and try
b. if the issue still persists you can try installing the upgraded BIOS version (but be cautioned - since failure during BIOS upgrade may lead to motherboard failure).
Well it is obvious, the date and time settings will be lost when you take out the CMOS battery from the motherboard. As far as computer not shutting down is concerned, you need to check the software and windows for that. It can be because of corruption.
Run Chkdsk repair on the computer.
PS: Turning off the computer by pulling the power cable out is not a healthy idea. I can damage the Hard Drive.
