When I powered-up the 770 this morning, it gave me a black screen (warning) that it had detected a "CMOS Battery Failure".
And, since I'm not the most computer-savvy guy in the world, is this something that I should be concerned about?
Is the battery necessary?
And how hard is it to replace, and where is it located?
The group's knowledge and expertese is greatly appreciated.
Thanks!
