Just take it out and pay attention to which side the “+” sign is on so you install the new one properly. Recently built PC desktop machines are usually easy, just open the side of the case and you should see the battery mounted either flat or sometimes vertically. When a new machine is built the tech enters the settings and manually sets the time and date on the motherboard when the battery gets weak often the time will be wrong on the motherboard itself and at bootup windows might be getting the time off the motherboard and thus will be wrong until it gets current time off the web…of course if you have no internet connection it won’t be able to get the time off the web. When I build a system I always put a new battery on the motherboard because you’ve got no idea how long that may have been sitting on a shelf in the warehouse the battery draining the whole time.
Most machines use a big hearing aid battery and they generally can be depended upon to last about three years. All current PC and I believe Apple as well use a battery to backup a small amount of information (in volatile RAM) that the system needs in order to start (aka CMOS). For those having issues after booting from (cold=machine off) there may be another consideration.
