I’m hoping someone can provide some insight into this.

I didn’t have (or wasn’t aware of) this problem until I bought a new APC Power Backup and plugged the phone wires through it (this is a new build). After that, the computer would start up whenever the phone rang. What’s even more confusing is that I set up a new pair of speakers yesterday and while hooking the right one up and placing it in position (while the computer was off), the computer turned on which tells me it may not be a problem with the APC Power backup.

I’m about ready to take the APC backup anyway and try another (it appeared that it had been returned when I bought it but it was the last one they had) but wanted to ask you all if you’ve ever encountered such a problem or can provide any insight.

Just another side effect of Viagra.

Humor is always appreciated and I know this sounds like a funny situation but certainly not from my perspective. Do you have any clue as to what might be going on?

Huh? Check the front panel power switch lead and be sure it is firmly attached to the MB Power On header and that no other wires are shorting the connection out. You may have a faulty power on switch. Is the Power on lead from the front of the case conected to the RESET switch by mistake?

the other thing to check is if you have any device able to wake the computer (ie magic packet on the NIC) it is less likely than a short but it can still cause this. Can be enabled in BIOS and in device manager and usually only limited to NIC's and Modems

you didn't really say whether you made any internal changes, so I am going to assume its a setting somewhere.

Try checking out your device manager and look at all the involved components' properties. Many components have a setting that allows it to 'wake' the computer. (lan and modem are popular culprits)

Make sure the phone is connected to the right ports on the UPS. Some have a management port and if you have that connected incorrectly it could cause your problem.

beat me to the punch

Done

I don't know how to check that other than turning it on and it turns on when I press the power button.

No
Everything is connected properly and securely.

Thank you all for your suggestions. After the initial response I didn’t think I’d get much help but I appreciate the responses from those that know what this forum is about. I’ll follow-up and inform everyone of what was actually causing this; hopefully, by tomorrow.

If anyone else has any ideas in the meantime, please let me know.

The power button has come loose from my case before. You can check behind the front panel of the case to see if the button is firmly seated and popped out from it's mounting socket.

?

I agree it's some setting for a wake-up.

Say, what sort of BIOS have you got?

Board maker?

Then again, you may have accidentally gotten a superhero PC that is always ready to answer the call. Do you find it flies off a lot?

It's a new one on me anyways

sheesh guys. simple solution.

Your MB has wake-up upon ring enabled. Go into your bios and it should be under power options/acpi/ect. This is assuming, of course that your system is connected via a modem to the phone line.

I'm going to have to agree with the wake on LAN/modem theory. Either that or your computer has become the subject of a new horror movie. :-)
