HP notebook schematic in PDF, archived as RAR, for a board written as 60050A2489301, which appears to be a typo of the Inventec number 6050A2489301, and based on the Intel HM77 chipset. Check the label on your PCB before relying on it. A diagram like this is used to trace power rails, follow the standby and main power sequence, read component values and locate test points while searching for shorts. Extract it and open in any PDF viewer, cross-checking the revision with the physical board.
