APC ES 750 Flashing Red Light & Chirping?
Hello
I've had this issue for the past month with my Backup UPS ES 750. Started with hearing this chirping sound coming from it. When I looked I noticed the flashing red light. I performed the following steps.
1. Power cycled the unit to no evail.
2. unppluged everything after turning the unit off.
3. disconnected it from main power.
4.disconnected the battery.
5. Pushed the power button for 20 secs.
6. Installed new battery.
7. Then reconnected everything.
Now it worked fine after all this and today it started doing the same thing! What is going on?
