Just asking, but does this thing happen if you use the laptop without battery, then turn it off normally through start menu and then remove the powercord from the walls plug?

What bad could this thing do then? (I shouldn't keep my battery removed from the laptop? Doesn't having it in the PC make it get bad later and doesn't having the laptop plugged in consume power too?)

Jaily, storing your battery out of the computer will not prolong it's life.  Read this ==> https://forum-en.msi.com/index.php?topic=137307.msg1029466#msg1029466

Okay, good to know. I though the battery gets worse if you keep it on all the time.

By the way, if someone has done this reset accidentally, what might it do and how to fix it?

There is nothing to fix.  It is not a problem nor is it a desaster.

Okay... I was just wondering as I've almost always used the laptop without the battery in it and recently I've started also to take out the power plug from the wall, so it wouldn't consume any power. So I dind't know it could do anything harm to the laptop, but you mentioned about something that this thing could do and I also noticed that I had a sudden FPS drop while gaming and also my webcam hasn't been fully working after that, neither have I been able to go to BIOS settings through F3 etc. keys in the beginning menu... And I think this FPS and webcam thing started happening pretty near to the first time I removed the power plug aswell. Could this be just a coincidence, or could it have something to do with this?

It rather sounds like a coincidence.  In any case, we should not discuss the problems you mentioned in this topic. This thread is not the right place for that.

Wanted to thank you for the simple method to reset EC. I have a VR420, running XP. Figured I would try splashtop beta un-supported platform. It booted to splashtop but took almost 2 minutes. Figured I would uninstall. additionally it did not detect the wireless lan card. So, I shut down and machine would not power back up. Lights would come on, but no display, not even on external VGA, no post screen options, nothing.

I cannot say for sure what splashtop did, if anything, but the reset of EC allowed me to boot to windows and uninstall it.

Thanks.

You say to wait 5-10 minutes with the battery and dc out... is this so the residual power in the caps drain or something?
Is there a way to speed this process up?  Like say, shorting pins on the battery socket's connector or similar???

From my own experience, you don't have to leave it out that long, but I'd leave it out for at least a minute before putting it back.

I mean why is there a such thing as ex? What does it store?
And by resetting it every time does that change anything in my system

(pardon if I'm confusing you or anything but Im quite new to this system related stuff :)

Nope, those are BIOS things they will kept powered by CMOS battery

It will reset EC RAM to defaults, like Wi-FI, BT, brightness levels, FANs and others to their defaults value.
So if you change any of them to custom one, at next EC reset they will be forgotten and auto disabled[which is their default state]
