When repairing an ADP-160ER without power output, focus diagnostics sequentially across the components listed in the technical schematic: Blown Blown MOSFETs and Capacitor Failure
Without this feedback loop, the adapter would output 30V+ and destroy the laptop.
The circuit begins where mains power enters the chassis. A standard fuse prevents catastrophic overcurrent draw. Immediately following are Metal Oxide Varistors (MOVs) designed to clamp high-voltage lightning or grid spikes. The Electromagnetic Interference (EMI) network utilizes custom line filters (FL1, FL2) and X/Y-class safety capacitors (CX1, CX2) to suppress switching noise from feeding back into household mains.

Ultimate Guide to the ADP-160ER Power Supply: Schematic, Architecture, and Repair
Before diving into the schematic details, it is important to understand the operating parameters and constraints of this power supply module. When repairing an ADP-160ER without power output, focus
Degraded optocouplers can send incorrect voltage information back to the primary controller. This causes the power supply to enter a continuous reboot loop, often manifesting as the infamous "Blue Light of Death" (BLOD) or a single beep followed by an immediate shutdown.

In the world of electronics repair, the power supply unit (PSU) is often the first component to fail. When dealing with laptops, monitors, or compact desktops, the ADP series of power adapters—manufactured by Delta Electronics—are among the most ubiquitous. One model, in particular, the , is a common 160-watt AC/DC adapter used in a variety of Lenovo and other brand laptops. For technicians and advanced hobbyists, accessing the ADP-160ER schematic is not just helpful; it is essential for diagnosing failures, repairing damaged boards, and understanding the intricate switching power supply topology.
