Schematic archive for project LT73, SD final release, with part number 91.4Z801.001 and board number 07257-1, dated 0506. The 07257-1 form and the 91.4xxxx.xxx part number follow Wistron conventions, so the board was designed by that ODM regardless of laptop brand. The material helps trace power rails, follow the charger and EC circuits and locate shorts. Unpack with WinRAR or 7-Zip and verify the board number printed on the PCB matches before using component values.
