1. Check in the BIOS that power on LAN is disabled.
2. reset BIOS: unplug PC, remove little round battery on board. Leave off for a minute then reset (you'll need to correct the time and date and reset any BIOS settings you might have changed, if any)

SchizTech :

So for my motherboard, would I just remove the little round battery on the board to reset the bios or is there another way?

SchizTech · Jul 17, 2015

The little round battery powers the chip that stores BIOS settings ("CMOS") and provides backup when the PC is unplugged. Removing that when the PC is unplugged restores all BIOS settings.

If it still happens, there may be a hardware bug.

Hmm where would the Power on lan option be normally in the bios? I just cant seem to find it

SchizTech · Jul 17, 2015

Theminecraftaddict555 :

Sorry, that may be called "wake on LAN." not "power on LAN." Every BIOS setup program is organized a bit differently so things may be in different locations, or the option may not be there at all.

Theminecraftaddict555 · Jul 17, 2015

The option is not there at all sooo

How would I remove the CMOS battery safely without damaging the mobo? is it okay to remove the battery with something metal like a small screwdriver?

SchizTech · Jul 17, 2015

Be careful, but a small screwdriver should work to pop the battery off. Usually there's a clip on one side of the battery you can push back a little.

Theminecraftaddict555 · Jul 17, 2015

According to the manual can I reset the bios by doing
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal
object like a screwdriver to touch the positive and negative terminals of the battery holder,
making them short for 5 seconds.)

*the part about the screwdriver is what I am asking about, will it reset the bios?*

SchizTech · Jul 17, 2015

Usually I just remove the battery for about a minute

Theminecraftaddict555 · Jul 17, 2015

So will the screwdriver part on the manual reset the bios too?

SchizTech · Jul 18, 2015

Shorting the positive to negative terminals after removing the battery just accelerates the process of draining power from the chip but if you leave it unplugged with the battery out that will happen anyway.

Theminecraftaddict555 · Jul 18, 2015

SchizTech :

I'm talking about not removing the cmos battery...but shorting it out without removing it with a screwdriver since I don't want to accidentally damage the cmos battery

SchizTech · Jul 18, 2015

I've done it dozens of times at least without damaging anything. The battery won't be affected.

If on the very long chance something happens to the battery, it should be available at radioshack or other electronic store (RS-232 battery)

Theminecraftaddict555 · Jul 18, 2015

Okay now my question is that will using the negative and positive terminals of my battery to short out the battery for 5 seconds ok? Will it cause any trouble?

SchizTech · Jul 18, 2015

Don't try to short anything. Just gently pop the battery out and everything will be fine. Wait about a minute before plugging the power cable back in and rebooting.

Theminecraftaddict555 · Jul 18, 2015

Should I still reset my bios even if I didn't change the settings in the bios at all?

SchizTech · Jul 18, 2015

It's a troubleshooting step and it won't hurt anything.

You can also check to see if the issue happens if you unplug the network cable. If none of this works, you have an odd motherboard power issue. Replacing the board would fix that if you aren't alright with living with the odd behavior.

SchizTech · Jul 18, 2015

Another thought: when you go to shut it off, are you using the Windows start menu? That's ordinary fine but an alternative is to press the power button on the case (don't hold it down but press it the same way as when you start).

When it starts up is there any delay or is it basically doing a reboot when it should shut down? IF it's this, it's not a LAN issue but could be a funny BIOS issue nevertheless.

Theminecraftaddict555 · Jul 18, 2015

SchizTech :

Yep, I am using the windows start menu to shut it off

What do you mean by delay? It kind of looks like it is doing a reboot but I can't be sure

SchizTech · Jul 18, 2015

I mean does it come back on right away, like a reboot? If it were a wake-on-LAN issue you might see it start randomly when it's off.

Theminecraftaddict555 · Jul 18, 2015

Update: I successfully did it! So this happened after I turned it on after doing the method successfully (taking out the battery etc.)
1. computer turned on for a bit and then shut down and then turned on again and told me that my bios settings were resetted to the normal defaults
2. restarted computer again when prompted by the system
3.logged in and computer took a while to load websites on the web and some icons on the windows notification area icons were blank and didn't show
4. restarted the computer and everything went to normal after that

Was that all normal?

SchizTech · Jul 18, 2015

Well part 3 isn't a typical part of the reset process. That might have just been a glitch. Everything else seems normal. Have you reset your date and time?

Theminecraftaddict555 · Jul 18, 2015

The times were already resetted so I changed it back to normal if that's what you meant

SchizTech · Jul 18, 2015

Yes, that's what I meant. Is the odd restarting behavior still happening?
