Yes we have had it, but it seems to be OK now. Would be interested to know what the cause was ...

2.4M pages approx 1600 students approx 250 staff 1 repro machine 7 copiers 21 desktop printers

We used FSE Design a few years ago https://www.fsedesign.co.uk/ They seemed good at the time, we could probably do with a refresh now though

We have a load of ASUS C204's, https://www.asus.com/uk/laptops/for-home/chromebook/asus-chromebook-c204/ not touch screen but similar spec and described as "Tough". They are fairly tough but the screws do seem to keep falling out of the bottom of them!

Both great ideas, but what about chewing gum. The kids very thoughtfully always leave plenty of it under the desks for just such occasions ;-)

Yes we had similar, from an order of about 250 Stones we had about 20 where the front facing middle USB port worked with USB sticks but nothing else, again fixed by replacing the motherboards under warranty

We don't have any experience of this model but Chromebooks appearing to be dead is a common theme with our HP Chromebook 14 G5's. In many cases a battery reset (disconnect and reconnect) resolves this but it does mean opening the case.

I just bought a couple of these Motorola E20 at £79 they are cheap, without all the bloatware (and they come with a plug :-) https://www.argos.co.uk/product/1244463?clickPR=plp:16:355
