Hi, More often than not, it is the internal battery of the UPS that causes switching off. In some instances it may be that too many devices are attached and drawing power from the UPS. In rare instances, it is the electronics controller that is at fault. 1. Since checking the battery involves opening the unit, you may be better off seeking the services of a qualified professional (there are dangerous voltages inside the unit even when off); 2. Try removing some of the devices connected to the UPS and simply leave the PC itself connected to the UPS. All others may be plugged in to the mains; 3. Checking if it's the electronics would be similar to # 1. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

I recently bought a 95 3 liter V6 pathfinder. The engine runs fine (for 154K miles) for about 20 minutes or so then starts to lose power and seriously misfire. Let it sit a few hours and then it will run...

Sounds like a cracked coil. Once the heat gets to it the fire goes everywhere. Run it into a dark garage and with it running, open the hood and watch for sparks.

Well, in most Cisco VoIP phones those lights are used to tell you if you have a voicemail. Have you checked your vm and cleared any new ones? This might be your issue ;)

TV picture goes out after 10 minutes of viewing with popping sound

It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.

Works for 20 to 30 minutes then it just cuts off

all I can think of is check the fan and see if you hear the fan running.
