Short in power supply??

[spaceman_333]

Howdy,

A neighbor just showed up in my den/office with his computer.

In brief, with everything turned off......when the electrical cord is plugged into the power supply, the keyboard flashes and the lights come on the router and stay lit. Have not hit the "on" button yet.

What, if anything, is wrong here??

Thank you.

If you turn the computer on does it boot?????

Sounds like wake on lan is enabled in the bios, that would explain the router part, not 100% on the keyboard unless wake on keyboard has also been enabled. Some motherboards can assign a keyboard key to power on the computer, that could account for the keyboard activity

Hi brianF,

Lan is enabled in BIOS. Wake on keyboard- disabled.

When my computer shuts down, the router lights go off.

Sometimes it boots ---sometimes not. It's acting weird. he said that everything was great and he was online working and all of a sudden the screen went black and a reboot started. When booted, the sound was gone.....then the cable connection went a few boots later.

Ah well, so much for explaining it, bah.

Could be a malfunctioning power supply, ram, short on the motherboard, overheating due to a bad fan, etc. All would cause the shutdown, why the keyboard stays lit, hmmm

Does it do it with a different keyboard

wish I could help more
