This may be the fuse burned or the battery problem
What is the electricity output? Look at the insurance is broken, not the case, the battery is generally a problem.
The battery is no electricity will appear this situation, first check the battery voltage, the battery is less than 9V 12V is no use, less than 10V is not start, check the charging circuit is a problem, no problem, then replace the battery OK,
Cause this situation
First, the battery long-term loss of power,
Second, the charging circuit failure, including electricity and other related aspects of burning electricity, the battery was released from the discharge,
Three motherboard failure can not rise
Start with the battery, multimeter DC file, the pen and the battery pole, see the voltage is normal. Boot to see what changes in voltage, if pulled down, the battery is a problem.
Or start with the battery is better, because the general UPS battery are consumables. I used to use the special small UPS is the third year for the block battery.
