"system battery voltage is low" message on bootup
I have a Dell Dimension 8300 PC, XP Professional w/ SP2.
The problem i am having is, about 9 out of 10 times when i start up my computer, it first goes to a black screen that says at the top:
"Alert! System battery voltage is low." and says to press F1 to continue, or F2 to go to setup. I don't really know what I could do in setup to fix this, and when I just hit F1 it seems to start up fine, and the computer seems to work perfectly fine once I get past that, but I am worried that it might be something I want to address so that it doesn't become something more serious.
If I was on a laptop or something I would think that there was something wrong with the battery, but it is just a PC, plugged in to the wall, and I wasn't even aware that it had a battery of any kind.
So, does anyone know what this means, or what I can do about it? Let me know if you need any more information and I will try to figure it out. Thanks.
