I have a back-up generator for my office, however when power goes out and switches to the generator, my computer turns off and won't turn back.
So I can not access my computer remotely, will this keep the computer on without shutting down?
Yes, this will keep your computer running. When a computer's plugged in to the BACK-UPS 700, I can unplug from the wall and the battery switch is so fast that I don't even see a screen flash. In your situation, you should also make sure your network is backed up (cable modem and any routers that connect your computer to the internet). If your network is not backed up, then any outages will take down the network and it may or may not recover after you switch to the generator--even if your computer is still running. This unit can probably cover both your computer and the network for a short time.
