Line 113: Line 113:

* TP144 - Reset? Or functions like one when pulled down by a 3.3Kohm resistor.

* TP145 - Connection between RTC and SMC, SMC nRST, sensitive to measurement (power LED reverts to red, but SoC continues running)

−

* TP146 - SMC Pin1, to RTC, Bluetooth, and 5GHz module. Front LED blinks red when pulled low.

+

* TP146 - SMC Pin1, to RTC, Bluetooth, and 5GHz module. Front LED blinks red when pulled low. BT and 5GHz module reset

* TP147 - Connected to RTC and pin4 of U1041 (ABLIC). 15v PFET enable.

* TP148 - Connected to RTC and Q1093 gate. Makes its way to U1041 Pin13 (ABLIC). When pulled low by 3.3kohm resistor, front LED blinks red until 15V unplug+replug. Must be pulled up to 3v3 by 10kOhm resistor, front LED blinks red upon pressing power.

Line 122: Line 122:

* TP154 - SMC I2C SDA

* TP155 - SMC Pin14, WiFi module pin 14. When pulled low in vWii, system powers off(???)

−

* TP156 - SMC Pin23, BT module PON signal

+

* TP156 - SMC Pin23, BT module PON/POFF signal

* TP157 - SMC Pin19, 5GHz module PON signal

* TP158 - 1.5v power rail A

Line 137: Line 137:

* TP170 - Eject Button (active low/pullup, pressed=0.0v, not pressed=3.3v)

* TP171 - SMC Pin28, Disc present

−

* TP172 - SMC Pin36, BT module pin 13

+

* TP172 - SMC Pin36, BT module pin 13. Standby Power-On reset?

−

* TP173 - SMC Pin37, WiFi module pin 7

+

* TP173 - SMC Pin37, WiFi module pin 7. Standby Power-On reset?

−

* TP174 - SMC Pin38, 5GHz module pin 16

+

* TP174 - SMC Pin38, 5GHz module pin 16. Standby Power-On reset?

* TP175 - Connected to RTC and SMC, pulses between 3.3v and 0v at 1Hz

* TP179 - Direct to DRH, pullup resistor?
