I followed the above steps on an HP rp5700 desktop. Now the computer time and date is set back to 2000. I have entered setup to change date and time. However, the date and time does not change as I navigate date and time…. no change at all. I have changed this before on other rp5700 desktops but this just wont change.

Someone out there HELP.
