Hi, i’ve bought an UPS APC BACK 1100VA connect with my wd sentinel dx4000… when plugging all plugs i press the shutdown button, then on back the dx4000… but it keep showing loading OS…please wait…
after half hour…1 hour…stil loading…
I thought maybe the UPS problem, so i plug it off from dx4000…
but its still same loading OS please wait… alr 2 days…
