I have a perx 625watt ups,I bot it before 3 years ,Now the problem is it restarts my pc on power failure and if my monitors brightness is set to high ,my back up time is 10 SECOUNDS ,How to solve this problem without buying another one ( I will buy an apc or wipro next year!) ,
Does a battery change help me to solve this?Is there any way to increase backup time and why my ups restarts on power failure? Is it due to battery prob?
Please help me ...
