(introductory note: it took weeks for my desktop to get repaired under extended warranty, during which time the motherboard was replaced, oh, maybe three times by two repair centers! It turned out to be a Windows problem somehow related to the video drivers. Out of the blue, mind you, but something that developed after a Win10 update. I believe I turned off future updates; we'll see. BTW, the second repair facility reports a flood of boxes are being sent to them following upgrades to Win10. )
MY REASON FOR WRITING TODAY...
Got the macnine back and it works, but the time and date are coming up wrong every morning. I expect to replace the CMOS battery and have two questions about the procedure.
1. Must I try to view my BIOS setup first and record the settings before changing the battery? This is not mentioned on the HP site where the battery-changing steps are shown.
2. According to instructions on the HP site, after discconnecting all the connection cables (why all?) and finally the power cord, I must push the power button. However, this step is not shown in the accompanying video. Is it necessary?

I followed up on this last night and saw that it was a good idea to push the power button before proceeding, because doing so helps drain the system of any residual electricity. The tip is found on an HP page having to do with a hard reset.
