    flexibel dah coba bos??? kl udah coba cek
    Cek di titik 3100 short atau tidak, jika short, cek komponen C3100, C3105, C3106, C3107.
    Cek L3162.
    Cek V3101 kaki 3 dan 4, short apa tidak, jika short lepas V3101 lalu cek ulang kaki 3 dan 4 yang di PCB, jika short, masalah dari N2000. Cek juga kaki 3 dan 4 V3101.
    Pasangkan batere/PSA, Cek di titik TP3100, harus terbaca tegangan = VBAT, jika tidak cek R3104, V3102, L3103, R3100.
    Hidupkan HP, cek di TP3100, harus terbaca antara 11-14V (catatan pada W830/W850 tanpa fleksibel, board atas, LCD akan blinking, jadi tegangan terbaca naik/turun). Jika hanya = Vbat / 3,7V, cek L3162, harus terbaca 1,4-2,8V. Jika tegangan di L3162 terbaca, tetapi di TP3100 = Vbat, maka yang menjadi masalah dari V3101.
