Just bought a new UPS, allowing it to charge as the manual says. I didn't hit the power button on the UPS. Does it have to be "on" in order to charge, or am I to assume that it having it OFF while some standby lights are on right now means it's also charging? I bought an APC BX1300LCD. Figure I'd invest in a larger one than I have now, since I'm getting an i7 soon. Opinions? Should I turn it on right now? I'm a bit picky to do things right. Thanks!
