Question

Electronics

Good evening, the computer worked fine, it costs two operating systems, after switching to Windows, a notification popped up - unknown USB Device needs more power than the port can supply. Winda advised me to pull out and insert some ports, I poked all the amps, even without all the connected devices there was such garbage .. I restarted the system a couple of times, and it all repeated. Then I JUST TURNED OFF THE COMPUTER and that’s it, it didn’t turn on anymore, no signs of life, nothing at all could your dead ... who knows, help ?!

Answer 1

unknown USB Device needs more power than the port can supply

- a device is connected to the USB port that consumes a lot of energy, more than it should be. Or a banal short circuit in the USB circuit.
Probably problems with power circuits - PSU, power circuits on the mat. board. Take it in for repair.
