"Internal battery" notices..what problems could a low battery cause?

Okay, so I've been having a few programs with my computer...this including slowness, poor wifi connections, and odd performance of wacom tablets.

The problems with a tablet are described in more detail here--> http://www.sevenforums.com/drivers/197500-wacom-tablet-malfunctioning-failure-pen-sensitivity.html#post1658350

Recently, before I signed into windows, a message on a black screen popped up stating something about my internal battery needing to be replaced. I'm on an HP pavilion laptop // HP pavilion entertainment PC.

Could the problems I mentioned above be related to the battery? I desperately need to be able to use my tablets for my major in college, and are majorly concerned with how they've been acting poorly with my laptop...could just replacing the battery work?

Also, would the 'internal battery' still be the battery that is capable of being removed from the laptop? Or does a laptop of two batteries?

This is the CMOS battery it is talking about. It should be replaced asap. But this is not a do it yourself job in a laptop. Better have some expert deal with it.

My laptop has a battery that is removable with a switch, are you sure it isn't talking about that?

Check this tutorial, but whs's advice to get it done by a repair shop is good.

How to replace the CMOS battery.

If you mess things up, you have no redress, if the repair shop screw things up you do have redress.
