This can inflame those that want to fix things.
I have an HP LaserJet 4100. I'm getting the error 57.4 which means it's either the fan or the DC controller. When I power up, the fan runs correctly for three seconds and then stops. This may be OK, but after the warm up I immediately get the 57.4 error message. Does this mean it's the DC controller or might it still be the fan?
thanks, ed g
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
