I emailed the aquacomputer support email address on Sunday but havent had any response yet
I replied on Monday so you will have to check your mail account - maybe it got filtered as spam or something like that.
Here is the original reply again:
"if the touch front does not respond anymore and the LED stays on, it is very likely that the touch controller crashed. This usually happens if the controller is flooded with false input.
Unfortunately there is not much that you can try yourself. You can detach and mount the front again to make sure that there is no strange contact problem.
If you want to give it a try: remove the four screws at the front so that you can pull it off (cover, glass and touch PCB). Remove the stand off pieces so that you can also pull the LCD from the main controller board. Use a ruler or something like that and slightly bend the pins on the main controller and LCD board sidewards so that they will definitively make good contact when you assemble everything again.
The touch controlled area is sensittive to electromagnetic fields so maybe something in your case is causing the problem. We have also seen problems caused by the power supply or even the case itself in the past. If there is some kind of ripple disturbance overlaying a signal it could also cause problems.
You could try to lower the sensitivty of the keys a bit.
If possible you could remove the aquaero from the PC and let it run out of it for a night (or the time it usually takes to come up with the problem) to check whether the problem is still present.
If you are able to power the conntected stuff like fans or pump directly so that you can remove the main power from the aquaero for a test, it might also help. The device will be powered by USB only in this case. It will only run the logic stuff incl. the display and touch control. If the problem is gone it might have something to do with the PSU.
Just a few days ago we had a customer with pretty much the same problem. He reported back that the problem was completely gone after he moved his system into another case. He was moving the system anyway and not because of the aquaero but in the end it proofed that external influences near the aquaero can cause this problem."
