Hi. The clock on my Acer will not keep the correct time any more and it doesnt change dates on the calendar either. Do I need to change a battery in my motherboard?
If you change the BIOS date and time and when you boot up next time and the date and time has changed back or is incorrect, then the most likely fault is a flat BIOS battery. Replace the BIOS battery, it maybe a coin type lithium 3volt battery. this is the most common type used in motherboards is a CR2030 lithium battery.
