    DP_INT_HPD 3.3v 3V3/5V_S0SW_LCD 3v and 5v This laptop without a battery connector turns off so the voltages go down after a bit. Anyway, there's no image besides the backlight, as mentioned above. Anything else I need to measure because I checked the whole connector diode mode all is good

    Hi guys. I have this A2289 with no power on state. The adapter is stuck at 5v 0.2-0.3a cycling. There was a bit of corrosion on D8450 pin 1 and C8495 pin 1(no stuff), which I cleaned and resoldered, and still no power. I checked the diode mode for all coils and with no issues all values are...

    I tried another ROM chip from a working board but stays on 5v. I blanked the original chip from the board and it goes directly into DFU mode now, What option is the best to choose to flash a new file ?
