Dell SFF 3020 and 3040

[bigal06]

Hi,

 

We have an issue on the two Dell PC models above in that the students have discovered if short out the USB ports it kills the PC until you pull the power cable for 1 minute to reset the PSU. We don't seem to have this issue on other models around school so just wondering if anybody else has this issue and any recommendations to stop this problem that only seems to be on the Dell SFF 3020's and 3040's

 

Many thanks

any recommendations to stop this problem

 

Proper classroom management?

Unplug the front USBs inside the case? Guessing they plug into the Mobo somewhere

If rear ports, if you disable the ports does it make a difference?

 

If connected to mobo by lead; unplug.

 

Or hot glue.

I agree but that is beyond my control

Yes, but when students require USB they start farting around the back of the PC since front would have been disabled which is bad!

Front ports causing issue at the moment and the phono/mic socket on the same ribbon plus unplugging/disabling them causes issue as above.

Looks like solution is to leave Dell on the shelf. We have a lot of HPs that don't have the same issue when ramming pieces of metal in them so not sure what gives on the Dell. Edited February 8, 2017 by bigal06

Brilliant - might stop them changing the keys around on the keyboard also! how they actually get time to do that without anyone noticing is beyond me
