    Ai biết lỗi này hướng dẫn dùm em ạ!!
    Dell Latitude E6420
    Không có sạc khởi động lên hình đúng 10s tắt, đèn báo ổ cứng, wifi vẫn sáng.. kích nguồn lại thì chạy xuất hình bình thường. Tắt đi khởi động lại thì lại chạy 10s tắt, lại phải kích nguồn lại
    Có sạc có pin hoặc có sạc không pin thì chỉ lần đầu tiên bị như thế rồi tắt đi mở lại thì chạy bình thường ( không tháo sạc ra)
    Bios lúc đầu là A07 . đã up lên từng bước A08, A21,A23 vẫn thế :(
    Chưa có điều kiện test bằng cục PIn khác :(
