USB Device over current status detected [ASUS motherboard]

Submitted by Druss on Mon, 2020-10-05 21:53

An ASUS ROGSTRIX B450-F gaming motherboard that I have had been working perfectly fine for a year. Suddenly though, booting up the system resulted in the following message on the POST boot screen:

USB Device over current status detected !! System will shut down after 15 seconds

The system would shutdown and restarting would result in the same message. I couldn't get into the BIOS either as the del and F2 keys did nothing.

USB keyboard not being detected during boot

Do you have a USB keyboard? Does it work fine? Does it also work fine once you boot into your operating system? Does it not work at all during the boot process before loading your operating system?

If your answer is yes to all of the above, then you've very likely been an idiot like yours truly and enabled the Fast Boot feature in your Intel motherboard's BIOS without reading the fine print.

Setting up temperature sensors with Ksysguard

Following my recent adventures with my motherboard, I wanted to set up a temperature sensor on my Kubuntu desktop, so that I could keep an eye on my motherboard temperature. Searching the repository came up with a number of potential options including ksensors. However, when I installed ksensors I couldn't find a temperature option; just memory usage and stuff.

Should processor fans blow out or in?

I had to clean everything inside my PC today due to heavy dust accumulation and in the process remove the processor fan to clean it and the heatsink below it. However, while I usually mark the "right side up" for the fan, I'd forgotten to do so this time. While it made sense to keep the AMD logo on top, I was still not confident to start the PC without being completely sure. Google spouted advice hither and thither, but the general consensus appeared to be as follows:

  • CPU fans should blow air into the heatsink.
  • Case fans should bring cool air into the cabinet.
