Question about Mustek PowerMust 800 (POWERMUST800USB) UPS System

1 Answer

The ups shuts down the pc randomly

Since a few weeks ago once a few days the ups stops functioning for about two seconds and completely stops the power supply to the pc, shutting it down forcefully. When I tested to see what happens when the ups gets no power by unpluging it, it works fine, powering the pc, so the ups battery still works. I already got corrupt files and I am worried that my pc components will get damaged. Can you please tell me what could be wrong and what to do?

My Goodman model GMS90703BXA has a problem wherein after a cycle, the ventilator / discharge fan doesn't shut down properly. It stays on after the burner has shut off and after the main fan has shut off. ...


Hello, usually this happens when the pressure switch remains open, this could be due to a blocked flue pipe, water inside the tube between inducer motor and pressure switch, or the switch itself is going bad. Condensation can form and leak back to the pressure switch through the tubing and causing an intermittent problem with the inducer motor running continuously

1999 Honda Accord randomly shuts down while driving


The ignitor in the distributor needs changed. This little guy can cause massive headaches. They work intermittently, but once warm, they knock the ignition spark off.

Hope this helps, vote if you think so thanks.

Laptop randomly shuts down


This problem might be occur due to old BIOS version installed on the laptop.
If your system shut down unexpectedly within 10-20 minutes while playing games or scanning the system which takes high cpu usages then the problem is of BIOS and try to install the new BIOS version.

I bought HP Pavilion dv5 6 months ago and fan not working


Your cooling fan sounds to have went out,causing it to overheat and shut down.It also could be something in the fan stopping it from turning.Try cleaning it or blowing it out with it off.But it mostly sounds to have went out.
