A place for collecting, gathering, and organizing notes for repairing & fixing microsoft surface pro 4 tablet/pc.

busted tablet #1

when testing the Schottky Diode with my meter i got 0.2V with the red probe on the left side of the diode and when the red probe was placed on the right side of the diode i got OL

i was able to remove the ITE chip this afternoon using hot air and board preheater. i had my hot air on the lowest setting with temp at 395 and the board preheater at 300

both surface tablets i have use the same logic board, ie. the X910540-007

	# This file contains pin mappings and reasonable defaults for Prusa i3 MK3S
	# printers. It will work with MK3 (non-S) by selecting the alternative filament
	# sensor. References to common community mods are included as well.
	#
	# Note: The Einsy boards sold by Prusa have defective firmware on the
	# usb-to-serial chip that makes the boards unusable with Klipper through USB.
	# While flashing Klipper firmware must be done over USB, the board can be used
	# via serial with no additional modification.
	#
	# To use this config, the firmware should be compiled for the AVR atmega2560.
