Dell optiplex 790 ultra slim

Hi All

 

Not sure how many of you run Dells in schools these days, as they're not cheap. We have them in each classroom as the teacher pcs. In 4 out of 35 rooms, we have an issue with keyboards not being recognised by windows during the startup procedure. They dont respond to any input on the log on screen (Windows 7). If you unplug, and then plug in, then all is ok, as windows recognises them as a new hid. We have flashed the bios to the latest version in line with Dells support call request, and have done the obvious like swap out keyboards, and changed the USB ports we use, all to no avail. The other USB peripherals seem unaffected.

 

Any and all ideas welcomed

 

Thanks all

We have hundreds of these machines on Windows 7. Dont have these issues. Have you looked to see if its an image or sysprep problem. I had something similar with sysprep back in the XP days on Optiplex 755.

 

Dells are just as cheap as other brands once you knock the website price right down with an account manager.

Thanks for the idea. Sadly, in Switzerland, Dell are expensive, but just about the only reliable supplier. We don't get the 8%VAT back over here either. The problem exists in 4 machines, these have all been rebuilt using the same image recently. We did this to try to rule out the image being the issue. The image was generated using one of the four, to ensure all drivers etc were correct, and hopefully removing any sys prep problems. We also built 2 from scratch, with image, and this also resulted in the same issues.
