Precision M4600 keyboard ribbon cable connector pinout
Is there any available information about the pinout of ribbon-cable-connector for Precision M4600 keyboard? it is 10 pin connector, but have no idea what is power, what is ground and what are the signal pins. Is it using USB connection? or else?
I know this keyboard is compatible with other laptops - Latitude E5520 E5520m E5530 E6520 E6530 E6540 Precision M4600 M4700 M6600 M6700.
I'm trying to fix the keyboard connector.

That level of detail isn't going to be available -- if the keyboard has failed, it needs to be replaced.

I found that the keyboard is using microchips ECE1117 chipset. It seems like it is using BC-Link communication protocol, not usb or I2c or ps2....
Still don't know how it works....
