  1. admin có nhận làm lại VGA laptop không? Mình có 1 laptop cũ Asus U80V đã chết VGA, làm tổng cộng 3 lần rồi vẫn bị chết tiếp. Do nhu cầu mình không cao lắm, chỉ cần lướt web thôi, còn lại mình có máy bàn rồi!

    Vậy hỏi ad thử là nếu làm lại theo cách của ad thì có thọ được lâu không?

    1. Mình không nhận làm lại bạn à. Bạn mang tới trung tâm gần nhà sửa chữa nhé. Thông thường thay chip khác thì thọ khoảng 6 tháng. Làm lại chân thì khoảng 1 – 2 tháng. Cái này cũng tùy chứ không chắc chắn như vậy được bạn ah. Vì nó chết lúc nào cũng không biết được. Mà những nơi làm lại chân VGA cũng không bảo hành
