Could we get someone to own that?
This reminds me - I've been meaning to ask how the switches actually work. There are two of them - one with the output marked PWR_BUT_in and the other with the output marked EB_MODE. I understand from the product datasheets that these are Hall Effect sensors, which in effect detect the presence of a magnetic field nearby. Sensor one (PWR_BUT_in) is located on the LCD side of the board at the top right near the notch. Sensor two (EB_MODE) is located on the processor side in the same location. From the position of sensor 1, I am assuming that it detects a lid opening, and the magnetic field is located in the base. I can't at all figure out where the magnet is for sensor 2, nor how it detects EB mode. So - long story short, where the heck are the magnets? :) Jordan -- Jordan Crouse Senior Linux Engineer Advanced Micro Devices, Inc. <www.amd.com/embeddedprocessors> _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
