Hello everyone.
I have received a board in for repair that has two missing resistors after another shop attempted to fix the battery connector. They're next to it and probably got blown off by the hot air gun. I've been able to find the boardview, and I can point the resistors in question, but there is no schematic and I do not have another board of this same model. Wondering if somebody has that board laying around and can measure for me these two.
PR8414
PR8401
In the attachments there is the layout and the selected resistors, along with the boarview (Kudos to Raimisz for providing this in another post).
Thank you very much in advance!
PS (Edit): Just as a clarification, these are not unpopulated pads, as it can be seen on any other pictures of the board (i.e. in the repair guide). The board powers on but shuts off after 3 seconds and never activates the backlight on the display, which would indicate that the board is looking for a voltage that does not see.
PR8401 (Attached to PU8400 , GND and another resistor) seems to be a simple voltage divider, but have no idea on what PU8400 it is expecting as an input, or even what IC it is. Searching for the markings don't seem to get me a compatible datasheet so I can not calculate that out.
PR8414 is either an input or the source for SUS_PWRGOOD, which also connects to PU8400, so it's critical to fix all this.

Very good to hear.
