I've been having issues with the date and time reseting each time I turn off my computer. It looks like I need to remove the CMOS battery for a few minutes and put it back in which will also reset the bios. I've watched videos about removing it but on my motherboard, there aren't any tabs to push out the battery. There is a little attachment underneath but I don't know how to use it. I'll edit with a pic in a few minutes.
Here it is!
