    Misi master-master semua, kiranya punya pengalaman atau cerita waktu nanganin laptop samsung NP275E4V & dengan senang hati berbagi ceritanya. Soalnya saya udah ubek-ubek ditemenin si Master (google) gak nemu boardview-nya, cuma nemu skematiknya doang :nangis:

    Kasusnya, laptop hanya bisa nge-charge dengan indikator lampu charge dan lampu adaptor-in menyala, ditekan tombol power tidak langsung nyala (harus beberapa kali), pas nyala tidak ada tampilan apa-apa, kipas tidak muter, drive optik tidak merespon, hdd tidak berputar. Setelah mainboard diangkat dari casing & disambungkan ke monitor menggunakan kabel VGA masih sama, sebelum dapet skematiknya saya cari voltase 5VALW & 3,3VALW ternyata cuma ada 5VALW aja, ukur meng-ukur nemu elco & kapasitor yg short.

    Namun setelah "yg dicurigai" diangkat ternyata elco & kapasitor tersebut masih sehat dan ternyata pas diukur ditempat dimana elco tersebut "nongkrong", resistansinya antara 1,9-2,2 ohm (normalkah nilai resistansi segitu?). Karena masih terindikasi short akhirnya mosfet & ic power yg men-generate 5 & 3,3VALW diangkat dan hasilnya masih sama (short), berikut foto komponen lain yg terukur short.

    Sekiranya para master disini ada yg berbaik hati mau memberi petunjuk, saya doakan ilmunya akan membawa dia & keluarganya menjadi penghuni surga yg kekal. Sebelumnya saya ucapkan Terima kasih
