There's a banner ad that appears for computer repair in Chiang Mai. The company/person is "Mr Wit, Eexpert [sic] Computer Technician". His logo features a crossed hefty wrench and a hammer, presumably to hit the computer with.

If you can't fix the problem with a hammer or a wrench, then the problem is likely electrical........................

The logo may be a pre requisite to try before calling on the expert.

Also noticed with some of these ads that they are showing a westerner. If that's the case, good luck to the guy for getting in there with his work permit. More computers that are sold, the more that are going to breakdown at some stage.
