Hi everyone out there, I have a problem with a compaq ups I have just aquired, I bought it really for the pure sine wave inverter inside, the unit works fine for five minutes or so then shuts down, it is not overheating the battery level is fine and the mains supply is fine, does any one know if you can program the unit to run longer with buttons on the front of the unit, I did not get a user manual with the unit, thanks for any replies, Dave H.
