Might seem to be a stupid question, but what happens if I accidently would clear CMOS when the computer is up and running?
Just how do you accidentally clear the CMOS when the computer is up & running?Originally posted by: steimm

I don't think anyone has ever accidentally done it. I'd imagine that there could be various results on a hardware or software level.Originally posted by: steimm

My tip to you: Don't do it.
no you do not turn it on with the cmos jumper in the clear position. you turn off your machine, disconnect all power from the machine and 30seconds. then you move the jumper over to the clear position and wait 30seconds. then put it back to the normal position, reconnect power and go.Originally posted by: toot
I'm not sure it's even possible.. Usually you put a jumper in the right place and when you next turn it on, it clears it then. I don't think removing the battery would clear it either, while it's switched on.. You'd have to switch it off for a while.
But hey, if you wanna try it..I think if you did somehow manage it, it _might_ not affect anything until you tried to reboot it..
But hey -- if you do, make a video of it and share with us!Originally posted by: eplebnista

lol - I understand the point - as I have stated, but I thought that someone in here actually knew... But don't compare mechanics with electronics - I don't think that's really fair.Originally posted by: severtki

... I've always wondered what would happen if you slammed your transmission into Rev while going 55... Anyone want to try and find out?
Probably nothing.Originally posted by: steimm

Same results as slamming that auto trannie into reverse at 55mph. NOTHING GOOD will happen to be sure. Only difference ... your mobo is cheaper than a transmission.
nobody around here stooopid enough to do this. go to another forum and ask thereOriginally posted by: steimm
I sure got the hint ;-)
But back to business, what it is REALLY going to happen? There is a lot ppl that "knows" but is it anyone that really KNOWS?
How can this be ?back to business?? This whole thread is asinine. Why not just fess up? Reboot the damn box and let us know what happens! Geeezzzz, what a waste of time and bandwidth.Originally posted by: steimm

Thx for a great reply!Originally posted by: Peter
The CMOS RAM is only fed by the battery when there is no other source of power. Even in ATX "off" mode, it's fed by the power supply through the +5Vstandby rail.
The "Clear CMOS" jumper has the battery current run through it. When you pull it or set it to the "clear" position, what you're actually doing is disconnect the battery.
So, if you move the "CMOS Clear" jumper while the system is on a (standby or fully) powered ATX PSU, absolutely nothing would happen to CMOS RAM contents. All that remains is the risk of an ESD zap![]()
(Disclaimer: The above is true for typical mainboard implementations. Some might have the jumper in the resulting power feed to CMOS, and some others might always run the CMOS RAM on battery. YMMV.)
That kind of stuff happens when the CMOS hits menopause...Originally posted by: steimm
by the way, I have done several "hot flash" of BIOS and that is no problem - but that might not have anything to do with CMOS - or?
