Help ! "CMOS Date/Time Not Set "

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello, I'm new to the forum and need help regarding a message when the computer is powered on. I'm coming from a Mac to a PC , so I'm not sure how to handle this.

I've been getting a message when the computer powers on, its shows "CMOS Date/Time Not Set " when I select F2 and change the date and time , then save the settings, it does not stay. I get the same message when I power on again.

It's a custom built recording computer,loaded with software, so I don't want to do anything to mess the computer up or lose anything. 

Does this mean that the battery needs to be changed? If so, can I just replace the battery or do I need to do anything else when replacing it?

I know on the MAC , I would just have to change the battery without doing anything else. Any info would be greatly appreciated

Computer info: 
ASRock Z370/OEM UEFI L0.01
Intel  i7-8700 CPU @  3.20 GHZ

	You are correct, all you need to do is change the battery on the motherboard. It's quick and painless to do and won't effect your software at all. It's just your typical CR2032 3v lithium button cell, you should be able to pick them up almost anywhere. I tend to spend on the best brand I can find so I don't have to change them again in a hurry but even cheap ones last for years. Edited by Xaltar - 30 Sep 2024 at 12:10am

	Thanks so much for the reply! I had read that, changing the Battery would effect the BIOS settings. So this is something, I don't have to worry about Correct?

	If the battery is dead then the BIOS is resetting every time the system is disconnected from power anyway. It will just load defaults (which it has done every time you see that message anyway). Nothing to worry about.
