Hi, I don't know why, but I was kind of expecting this kind of answer ;-)
>> Is the laptop's keyboard only option the >> Chicony P/N MP-03756GB-5287. > > and associated variants, yes. In fact the question I had in mind was more: If there are such associated variants that can be (almost) drop-in replacement, but with backlighting... Because I naively expected the producers to reuse their designs when adding such slight variations... So the answer is no... Too bad >> Or maybe the laptop case can be modified to allow placement of a few >> leds around the screen that would get light on the keyboard.

I would not have expected this to take significant work. It could even be done by careful drilling, without redesign. > that's assuming no LED circuits are needed and > there's a convenient place to draw power off of. if it was under PWM > control of something (to change brightness) that's.. 3-5 weeks of PCB > design work and PCB assembly, 1-2 weeks of component sourcing and > verification. Here I show my almost complete lack of electronics-fu, I thought LEDs were so low power that they could get piggybacked to the display power line with just a 1K resistor added, and maybe a switch, to avoid needing to route a GPIO there just for that. > *deep breath*.... get a small $2 torch from walmart :) That's where I'm coming from, and where I expected not to stay... :-) Especially as this is absolutely not eco-conscious, the one I got lost leds after just a few weeks of light use, and now is getting useless. Maybe that was bad luck, but I'm not holding my breath with a new one... But thanks for the very detailed answer. -- Vincent Legoll _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
