Rob from Tarzana, CA

Rob recently replaced his laser printer. But since he connected it, he gets a beep on his backup power supply. Didn't happen until he plugged in the printer, and when he turns it off, it stops beeping. Leo suspects that the battery may be wearing out and it's pulling too much of a load. As UPS wear, the capacity may go down, and a little extra in wattage can make the UPS choke. Plus, Rob may need to plug it into a different circuit, not a different plug. He might need the next model up.

Jay from Providence, NC

Another tip is to look into whole-home surge suppression, installed by an electrician.

A much better solution is to get a UPS, or "Uninterrupted Power Supply."

John from Moorpark, CA

John has to replace his A/V receiver. He's lost two in the last few months. Leo says that sounds like an indication of "brown power" that's surging or spiking. Scott agrees, and says a power conditioner would be a good thing to get. It's not cheap, but it could help. Scott also says that if speakers are designed to use a specific receiver and he tries to plug them into a different one, it could strain the receiver more than it should.
