Resurrecting a CyberPower 320SL
After several years of service the unit beeped, unnoticed by the user
until it shut down her computer. Got a new one for her, but thought I could use the old one on my TV, since it was probably only the battery. Yes, I know, I'm a cheapskate! But the battery didn't bring it back. The power LED doesn't light up, and there is no power to the battery-supplied recepticals after being plugged for 24 hours. I have no user's manual. There are two external buttons, one on the end that is easily pushed since it projects up to the surface. The other is a little tiny button way down in a hole. I've pressed both with no effect. What am I missing? TIA Ed |

It seems the unit is smoked , check breaker and if installed new battery and
charged for 24 Hours, then FET's are shorted. For more info about troubleshooting please check this site. http://www.cyberpowersystems.com/faq_sl.htm#q4 Best Wishes Cyrus |

Cyrus,
I've now found the user's manual online. Thanks. I put the new battery on another charger for 24 hours, then reinstalled it in the 320SL. Also found the red power button had fallen down into the case, so I reinstalled it properly. It now emits 3 beeps when it is turned on with the power button, and when plugged into the wall outlet. Power LED still not lighting up, and no power to battery supplied recepticals. Is the circuit breaker button supposed to be momentary contact? The users manual says it should be "in for normal operation" like it should stay in when pressed, and pop out when it trips. Doesn't act like that. It doesn't latch when I press it.
