    coba angkat U605nya boss, atau lepas jumperannya bla sudah lakukan trick stuck

    ukur jalur BATT_UART_RX .. adakah resistansi di PIn tersebut ?

    jumperan udh di lepas , kondisi kembali ke loading stuck

    klo di ukur hambatan dalam ada (pke multi tester ,jarum merah ke ground,jarum hitam ke pin kaki 9 /A1)

    tapi tegangan nya 0, alias tidak mengeluarkan nilai 1,8v

    sedangkan di titik UART_TX pin 8/A1 nya keluar teg 1,8v nya jadi yg di kaki pin 5 /B1 kluar teg jadi 2.8v

    sedangkan yg di kaki pin 9/A2 nilai nya 0 jadi di kaki pin 4/ B1 tdk mengluarkan teg sama skali , yg menuju BAT ID


    kebetulan saya lg tidak ada mesin gemini normal buat di comper , mau di cek yg di kaki pin 9 (batt_uart_RX) ada teg 1,8v sumber nya apakah dari CPU di kaki pin AC-23

    dan sumber in put nya dari mana msh binggung

    he he he ....

    mohon pencerahan nya om
