Vận hành mạch:
Đây là dạng mạch nguồn &#8220;kinh điển&#8221; mà ta sẽ gặp hoài trong tất cả các mạh nguồn trong laptop như nguồn RAM, Nguồn Vcore CPU, nguồn chipset, nguồn chip VGA&#8230; Vì nhánh 3v3 giống hoàn toàn với nhánh 5v nên lqv77 tôi chỉ vẽ [...]]]></description>

		<description><![CDATA[Laptop: Mạch mở nguồn ADBAT và mạch quản lý sạc Pin

Tại sao lại gọi là Mạch mở nguồn ADBAT?
Khi bạn chỉ dùng ADapter thì mạch này sẽ mở nguồn ADapter, còn khi bạn chỉ dùng Pin (BATtery) thì nó mở nguồn BATtery, nên lqv77 tôi gộp chung lại gọi là nguồn ADBAT. Để dễ nhớ, [...]]]></description>

		<description><![CDATA[Laptop: Mạch kích nguồn

Về nguyên lý chung, mạch kích nguồn laptop đều tương tự như hình bên trên.

 TPS51020 là IC nguồn 3v3 và 5V cấp trước.
IT8511 là SIO.
A/D Dock In là nguồn adapter cắm vào
VBAT là nguồn Pin
AC_BAT là nguồn cấp cho toàn mạch, nó có thể lấy từ Adapter hoặc Pin.
