Ok, since I've made this thread anyway, I suffer from an additional problem :
whenever the electricity comes back, (as in, when we get mains light again) my computer restarts.
I've currently chained 2 (yes thats right, i've put TWO UPS in series) UPS together, but my PC STILL restarts.
This is a typical sequence :
1. powercut
2. UPS takes over load (but it keeps switching modes as if its getting mains power for a second then goes back to battery... it happens very fast and it makes a very fast clicking sound, like, the sound of battery load > sound of going to mains power > battery mode).
3. genset comes on, and I continue work
4. mains power comes back
5. (genset is still on)
6. PC loses power for a milisecond, and restarts.
7. genset is turned on.
steps 4, 5, 6 happen extremely fast, and i think there's some kind of problem with the electricity supply too in our colony.
I'll call an electrician ofcourse, but what do you guys think?
