Do not know why, the day before using a good, second days, plug in, found that the computer is not connected, UPS on the backup lights have been flashing, and has been "drip" ring. Unplug the ups plug and socket, the computer is energized. Is it UPS or something?.
UPS power alarm, power supply has not enough... With computer..... Let it plug 10 minutes, plug in the computer can boot.... remember to open the power switch UPS.... otherwise it really bad... Is the simple point that you just give it a separate charge, does not go bad the...
The electricity hasn't been plugged in yet Don't you take the call through the battery can not boot the computer to see www.upsbbs UPS forum to provide detailed information UPS
UPS (Uninterruptible, Power, System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply. Used primarily to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power through the inverter conversion method continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices usually provide protection against too large voltages and too low voltages.
If the charge is still a day, this problem may be a few reasons, the general possibility of the first two problems.First, voltage instability, the range of change is too large.Two, UPS input socket bad contact.Three, UPS's own problems.
BACKUP light flashes, stands for UPS, currently works in backup mode (battery discharge), other lights are not bright, may be UPS without city power input or city power abnormal.
