It does sound like a new battery should fix this.
Does it work properly after this happens?  Does it lose time while it is up and running?  Have you had any power surges lately that you know of?
It is possible that the cmos has been damaged and needs replacing.

Hi,

Have you made any changes to the computers BIOS?

Has the computer been off for a long time?

There is a few things to try,

1) Boot the computer up and go into the BIOS, go to save settings and say yes, then let the computer restart and leave it on for about 6 hours,
    Restart the computer and see what happends if that message comes up, then try shutting it down and boot it up again and sees what happens.

2) reset the CMOS:- this is normal done wioth a jumper and turn the computer on and it should not boot up. (if there is not a jumper take the battary out and turn it on)
   This sould flush out all settings, this could be that there is something wrong with one of the settings, and causeing the Bios to report it is wrong...

Let me know what happens and we can take it from there.

lochanravi, for you information the CMOS battery is a CR2032 coin battery and cost a couple of dollars.  This small outlay can either eliminate the battery as the source of the problem or fix it.
