Yeah you are lucky that it’s nearly invisible . I dismantle my 3pro and found out that ribbon cable at the connector side is probably broken (it looks like some pins are melt together).
However I didn’t try to repair just yet. If I succeed I will post my result.
about this version:
there is high pitch noise from screen on low brightnes, problem with opening laptop (on left side of hindge screen is scratching laptop), if i max out brightness screen will just turn off and i have to close and open laptop.
yesterday i recieved my 3pro. I was lookin to unlock my bios, but my bios version dont match yours from the tutorial.. can someone pls tell me what version i have ?
