    ok just got back my ups from in-warranty service . now the problem is , whenever i turn off the main and run on the ups , it works fine , but when i turn the power back on while the system is running , it restarts for some reason . i ran with just barebone m/b and monitor , still the same problem . switched off ups while in bios , works fine , turn main on it restarts . which is the culprit ? UPS /SMPS or M/B . even cleared cmos and updated the bios .i just have monitor and system connected to the ups .

    Config A7V8X-MX/2600+/512/17' samsung/zebronics 350watts

    ups specs
    Cyber UPS
    500 VA with built in var
    voltage : 150 VAC - 275 VAC
    Battery 12V 7AH SMF-One

    Configure UPS service for Manual startup in Administrative Tools / Services. Check settings
    Check UPS signal polarity and test if it is not set to negative for power failure or restart.
    Please tell if this helps.
    Merry Christmas :D

    thanks and thanks :) .

    . i tried with ups service enabled and disabled , same result . i get the prob in linux too and while running the pc without any drives and just into bios . wierd thing was , when the service center tested the ups after repair few days back , they attached a bulb and tested it . the bulb went bright and low when he switched back and forth . it didnt go out completely but brightness changed . i suspect voltage fluctuation or do upses normally do that ??

    will run a few more test . how do i test for earthing/grounding problems for smps/pc/ups ?? i got light shock from pc plug attached to smps when i removed it from ups and touched it accidently . was weird koz the system wasnt connected at all .
