Overheating: Power Options, supply voltage, powercfg -energy errors?

[treehouse]

As you are disabling the card reader, and still getting powercfg errors, then maybe the system is still detecting the disabled device as being active.

See the link I posted earlier. I'll post it again for your convenience: USB Port Remains Active for Disabled or Safely Removed USB Device | Microsoft Support.

I feel it's unlikely to be related (although I have to say I haven't got a clue what's going on). I'm not sure what it would mean that the system is still detecting the disabled device when Explorer isn't showing it (and I didn't try putting a card in, but expect it will just be a dead slot doing nothing). As I say, since powercfg -energy isn't actually reporting correctly or even writing legal html, I'm not sure what to make of its output! Regarding the linked article, it's a bit difficult to know if it's talking about the same issue, since there's no evidence of the card reader still being active (like having an LED on). If write attempts are being made, there's no error popping up in normal use - just these error reports from powercfg. Are we sure card readers aren't displayed in Explorer normally, like my DVD drive is always shown. They behave the same way - if I try to navigate there, Windows says there's no disk in the drive and to install one to use it (although they can be selected on the right hand side of the screen). This may be normal behaviour, and powercfg somehow corrupted.
