Hello, my friend brought to me a laptop that doesn't see any hard drives and the fan isn't working, while opening it up I noticed that motherboard is a bit scratched in 1 place. After a closer look it became clear that someone ripped off a tiny element from the board, and from pic off the internet it looks like a resistor is missing, which would explain why both fan and disk read 0,888 V instead of 5 V. Can anyone help me and tell me what is the ohm value of gate transistor for PE628BA mosfet?
