A couple of questions for @Atom80 and @baloney
1) Where can I buy additional power supplies for the Aero 15x please? I could use a couple of spares.
2) I've noticed a very faint clicking noise that has just recently started coming from the rear of the laptop, it sounds like 5 or 6 clicks in quick succession, then nothing for 5 seconds or so then it starts again. Is this one of the fans on it's way out?
For first question Atom80 could answer you; For the second question it may be caused by the interference of the fan & mechanical parts. My personal suggestion is that try to re-screw the bottom cover also the fan if possible
