Any cure for a washed out keyboard
The first XO casualty at Nepal's pilot schools a few days ago. A second grader washed his XO because it had gotten too dirty. Thankfully, the display, cpu and motherboard seem to be working fine. The keyboard is non-functional and the mouse is nominally functional. Anyone know a fix for a washed out keyboard besides complete replacement? -- Bryan W.

Re: Any cure for a washed out keyboard
It's already been two days and it is quite dry. the keys don't respond at all. The touchpad works but only responds to heavy pressure.

Re: Any cure for a washed out keyboard
Hi, the best thing you could do is to put the device (keyboard) into a bathtub with distilled water. No joke! after one or two days the electrolyte ingredients will be washed out. After that drip of the water and be patient one or two days. The device has to be very dry before you should activate the device. Maybe the display do not like it. I am always treating sunken electronic devices that way, including still cameras. A good alternative is ethanol (but not denatured alcohol!).

A good alternative is ethanol I mean ethanol 96% , better 99,* % Best regards, yokoy -- ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Any cure for a washed out keyboard
I haven't had a soaked olpc (yet), but most of the other devices that hand these kind of problems where much simply cured by : - being taken apart - carefull cleaning with a cloath, especially for the tip of flat cable going to a FPC connector which some dirt (oxidation? short circuit? isolant?) usually accumulate. Saved a wirless phone (display FPC problem), and a smartphone (keyboard FPC problem) that way. If that doesn't work, yes you should certainly try washing the keyboard board and plastic membrane.

I figured that it was the impurities in the water that screwed up the keyboard not necessarily water itself. Does it have to be a large quantity of water or just enough to fully submerge the keyboard? Perhaps I need a lot of water in order to get enough dissolution The more the better. But the best way is to do it in more than one pass, every time with fresh distilled water. In that way the keyboard has to be submerged fully, not more. yokoy ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
