Safe way to unplug a computer

Hey LTT,

So every time I unplug my computer the Bios settings get messed up. Last time it messed up so bad, that my computer couldn't read windows. (Something with CMS or something). Not knowing it was a bios thing, I reinstalled windows. So I'm finally annoyed enough to make a post. I do this:

Shut down

unplug

 

My motherboards LED's are still on when I unplug.

 

Is there anything I can do to avoid this?
 

Thanks!

replace the cmos battery if your bios keeps resetting itself, the motherboard LED's will stay on for a minute or so after unplugging because there will still be a charge in the system to get rid of that charge just press the power button on your case after unplugging

Turn off the psu before unplugging it and wait untill the motherboard light turns off. But i have never had that problem, maybe if you unplugged from the wall and then from the back of the pc?

turn off the psu switch, unplug the psu cord from the psu and unplug from the surge protector and unplug the surge protector from the wall, that's what i do everyday when i turn off my pc.

Every day!?

God you're going through extra steps for no reason...

 

 

As for the OP, change the cmos battery on the motherboard.

There s no difference between turning off the switch on the PSU, pulling the cable out of the PSU, pulling it out of the wall and switching it off at the wall. These all break the circuit in one way or another and none are safer than the others.

I would suggest you test or replace the MB battery to make sure this isn't the issue, but it probably isn't an issue with unplugging the PSU.

Thats what I was thinking

The bios doesn't reset itself. Should've said but it goes to a random time when I was overclocking. BSOD's

 

Also the LED's stay on when the computer is shut down, not after it is unplugged. 

 

Shut down, hit power switch, press power button, pull plug.

Wouldn't hitting the switch do the same thing as pulling the plug?

Pulling the plug can sometimes spark the power supply. You want to hit the switch to the off position to cut the connection.
