This laptop doesnt charge or turn on. no leds etc. i found that the x20ppd ic was burned and replaced it. VINT and ACK pads on the ic where shorted. Removed short on VINT by replacing another x20ppd which was on the other side of the board and which was also also shorted. fixed short on ACK by removing a component(E08 1 N) which was getting shorted. the laptop still doesnt turn on. i guess the removed component is needed can anyone tell me what component this is and what the value is? also there is a resistor right after the ACK pad. according to the pdf of x20ppd it should be 10k-200K ohms resistor. my multimeter is showing me 0,5M ohm. i guess this resistor is bad also? if so could i replace it with a 100k ohm resistor? thx!

From the silk screening, ‘Q’ = transistor or mosfet.
the package size appears to be sc-70. Have not found a match to the markings, yet. -
thx mate. anyone else have an idea what transistor/mosfet this could be?
Edit: there are a lot more of this same exact mosfet transistor on the board. Is it possible that I can take one off and measure it? If yes, how?Last edited by Hw31; 12-27-2023, 03:56 PM.Comment
