Solved Green light inside desktop stays on even when unplugged

September 6, 2013 at 09:08:34
Specs: Windows
I have had a tower computer for 8 years now. Last night I seen a green light inside the computer that I have never seen before. When I unplug the computer the green light is still on. When I pulled the side panel of the green light is on the computer board. Is this supposed to be there or could it be a tracking device on my computer

I'd bet a ton of money (if I had more than $.1 in my pocket) that the light you are seeing is an LED and consumes VERY little power. It may be running off the battery on the mother board or even off the residual charges in the myriad of capacitors all over the place in there. Either way it is normal and should not be of any concern unless it goes out or turns red! :)

Very unlikely to be a tracking device or anything sinister. It can have various meanings but if the computer is working normally I would be inclined to ignore it.

Always pop back and let us know the outcome - thanks

Thank you. for you help. I just never noticed it before. Odd the light is still on even when I disconnect the power cable.

Did you leave computer unplugged from domestic power long enough for the motherboard to discharge?

With it unplugged if you then press the power off/on button for about 20 seconds it should go out. Whether it will stay on again later remains to be seen.

Always pop back and let us know the outcome - thanks

Re #4

Yep an LED low discharge was my thinking exactly. My 2nd line in #3 will almost certainly put it out. What is less clear is whether it will stay out after a normal power off - maybe if something has got stuck.

Always pop back and let us know the outcome - thanks
