Question about Electronics - Others

Open Question

My powertech MI-5085 500w stopped working and the overload light is on , I have unplugged the laptop and printer it is connected to , but still the light comes on as soon as you turn on the inverter. Had the battery checked and was told it was all but dead , so I have replaced it , I was just wondering if there is anything else I should check as the unit is still showing the overload alarm. Thanks for any help , Dan Frost.

Red light on and beep sound contionus came

Hi Subramanian,
If this is a small desktop UPS like the one pictured in your post then it is most likely overloaded. If you have a printer plugged into the UPS then try unplugging it from the battery backup outlet(s) and into the surge protection outlet(s). Other things to try would be to unplug connected devices until beeping stops... and a good away to narrow it down is by unplugging one device at a time to find the one causing the fault. If one device is the cause then plug that device into a surge outlet, another UPS, or into the building outlet -- if not then plug it back in and try another device until you find the one that is overloading the UPS. **There may be more than one device that is plugged into your UPS that is overloading it**
Hope this helps. If you would like more assistance please give me a call: 407.380.9200.

My pc wont continue booting because of usb overload

what makes you think its usb overload ?

Check your computer's power cable and the power cables to any devices connected to the computer. Make sure all cables are firmly plugged into electrical outlets and into the computer and other devices. If you have an extra power cable for your computer, swap it in to see if your computer's power cable is the problem. Remove your computer's battery, if it is a laptop, and connect the computer to a electrical outlet to see if it will start up. Sometimes a discharged battery will prevent a laptop from powering up. If your laptop still won't power up, remove the power cable, replace the battery and try to run the computer off battery power. Unplug your computer and plug a lamp or radio into the same electrical outlet and see if that device works.
If the lamp or radio doesn't work, the outlet is the problem. Unplug your computer and open your computer's case, if it is a desktop system. Look for loose cables, cards and connections and attach them firmly. Blow out any dust with a can of compressed air. Also, check your computer's memory chips to make sure they are all plugged in and seated properly. Close the case once you are done and plug in the computer. Disconnect any USB devices connected to your computer and try to power up the system. Sometimes a USB device not connected properly will stop a computer system from powering on. Disconnect any new devices recently added to your system. Sometimes new devices will conflict with other hardware within your computer and cause an overload on your computer's power supply. Disconnect any other devices connected to your computer such as the keyboard, mouse, monitor, printer or scanner and plug your computer into a electrical outlet by itself. Check to see if the computer works. If does work, shut it down and connect just one device, such as the monitor. Turn on the computer and monitor and see if everything works. Continue connecting devices until you find the one that is stopping your entire system from powering up. Hope it helps.

    My refridge and freezer would stop working

    there is a saftey overload switch on the compressor when the compressor is over heating it cuts out. when the fridge is turned off it resets the switch. So now the compressor has burned out totally. you more and likely need a new compressor
