dell latitude 5490 bios

[LBTT1121]

cảm ơn bạn,
tôi vẫn thử,
máy tính xách tay vẫn khởi động, phím caps lock có đèn sáng liên tục, đèn nguồn 2 màu hổ phách và 1 màu trắng nhấp nháy
khi tôi nhấn nút nguồn rồi nhấn nút d, màn hình chuyển sang màu khác rồi không có gì nữa,
CPU không nóng lên chút nào, vẫn lạnh khi tôi chạm bằng ngón tay

power light 2 amber and 1 white ligt blink ---> CPU error

Hello, I have this computer and I cannot install Windows because after formatting it asks for internet activation. I bought this laptop at a swap meet while it was turned off. Please I need your help with a clean bios. I will always be grateful
