Chris; For once I disagree with you. I leave my m-power, on my desk, on ac power, all the time. When not in use I close the cover, but do not close the velcro. It has not had any effect on my unit. As I am writing, there is no sign of my unit being at all worm after just opening the case. I mainly close it at night or when not in use to keep away dirt and dust. I have 7.2 and no such problems. I have never heard of this happening before. Good luck on solving this problem. Is he putting the ac adapter through the hole in the case or directly into the machine. If using the hole in the case, try putting it directly into the maching and closing the case. You will not be able to velcro it but it will keep it clean while not in use. The chord going around the side of the back of the case will prevent it from closing all the way. Terry Powers

You close the case, right? That means that air cannot be exposed to the BrailleNote. This is especially important when charging the unit, as the electricity would heat up the battery, hence the transformer getting fairly warm during the fast charging process. If that heat couldn't escape, it could just build up and up in the BrailleNote, and eventually the unit would be so hot that smoke may be generated and, in worst cases, the unit could even explode and start a fire. So this is why I recommend to you all never to leave units, including a BrailleNote, closed in their cases, especially units that don't have a fan or places where heat can escape, to which the BrailleNote is a good example. If any of you disagree or have further comments or queries, please let me know as I'd be very interested, but as I have got a GCSE in physics, I should know all about how electricity works and what would happen in these situations. Thanks in advance.
