I made this modification to my LCD this evening. I decided to use SMD components to keep it tight.

I replaced the 10K SMD resistor with a 150K, then soldered the ground side of an inverted 10uF 16V Tantalum SMD chip to the ground tab on the side of the keypad cable connector (same ground point used in the original mod). Then I tied a wire between the + side of this SMD cap and the signal side of the SMD resistor. It works perfectly, and the power button still allows manual control.

I avoided issues with the flex ribbon cables by not disconnecting them at all during any part of this process. The only cables I found it necessary to disconnect were the speaker connector and the flourescent bcaklight connector. These need to be disconnected to allow the case halves to open fully.

Thanks for a great mod, Coyote.
