Hi: I do not know if this is the correct place to put it but i have a issues in the last several days. Ever since I installed mu uninterrupted power supply (APC) /surge protector software in my windows 7 ultimate I am having this continuous LED light being on after computer shutdown (once a day atleast) and even by uninstalling the software for my UPS (apc surge protector) I still get the same issue. I do not know why the green power LED light stays on often at system shutdown? I have checked all power settings and all are as usual. The software was "powerchute personal edition". Before installing the it all was normal. Any help is appreciate it.
