Thanks very much indeed for sharing the information. Yes, you are right. Thanks for pointing out the mistyped CLR_CMOS jumper positions; I have just checked the 700540-501 LARRYBIRD-B H61 manual (http://support.hp.com/us-en/document/c03506231) again and confirmed that the 1-2 position of the CLR_CMOS jumper is for CMOS clearing whereas the 2-3 position is for normal operation. Nevertheless, readers need not panic over the mistyped CLR_CMOS jumper positions because there are only two settings for the CLR_CMOS jumper; you can't go wrong in switching between the Normal Operation Mode and the CMOS Clearing Mode and it is not necessary for you to find out the actual pin numbers.
As for the removal of the CMOS battery, I did that to avoid draining of the CMOS battery during the CMOS clearing process due to grounding of the CMOS transistors. That is just a personal preference.
Steve, could you keep us informed of any clashes with BIOS and drivers in future Windows 10 update, please? In principle, the HP ENVY 20 TouchSmart All-In-One PC should function flawlessly and consistently after updating the BIOS and drivers; but who knows what could happen. Thanks!

Sorry, I wasn't aware that the HP Envy 20-d113w used more than one brand of motherboard. This is the first one I've had to work on, and it probably won't be the last since the owner has another six of them as POS machines in his restaurant.

That was a general statement to highlight that some motherboards has a dummy pin just to hold the CLR_CMOS jumper. I thought that was unambiguous and didn't think that you will misunderstood that statement. Sorry.

Your symptoms were exactly like the ones I experienced on a customer's machine. After an hour or so of attempting to clear the CMOS without luck, I began to go into 'f*ck it' mode since I couldn't make it any more dead than it already was. I just started rebooting and moving the jumper back and forth between the two positions and then I took the jumper completely off and powered it on, and by some miracle it booted! Don't lose faith yet!
