This HP 15-fd laptop arrived at the workshop in absolute pieces. It was a total disaster zone: a smashed LCD screen, cracked back cover, broken palm rest, destroyed keyboard, and a malfunctioning IO board. Most shops would have written this off as e-waste, but I decided to take on a total reconstruction.

To keep the repair costs down and save this machine from the scrap heap, I tracked down quality used replacement parts and went to work under the microscope to repair the damaged IO board.

Watch the step-by-step rebuild as we transform this completely broken laptop back into a machine that looks and runs better than new—all without breaking the bank.

Is a laptop coil tester worth buying, or are you better off learning how to diagnose motherboard faults with a multimeter?

In this video I test a popular laptop coil detector on a working motherboard to see how reliable it really is. After comparing the results, I demonstrate how to correctly measure laptop power coils using a digital multimeter in Voltage, Diode and Resistance modes.

Instead of relying on a dedicated tool, understanding how to interpret these measurements will help you diagnose power rail faults on virtually any laptop motherboard.

📌 In this video:

This dead laptop wouldn't power on, and the fault turned out to be severe liquid corrosion on an ITE Super I/O (EC) controller.

After cleaning away the oxidation, most of the pins were recovered, but pins 125, 126, 127 and 128 were too badly damaged, and the original motherboard pads were completely gone.

Instead of replacing the Super I/O chip, I carefully cut into the damaged corner of the package to expose the internal lead frame, then rebuilt the missing connections with jumper wires and repaired the damaged traces on the motherboard.

In this video I show the entire process under the microscope, from corrosion cleanup and inspection to rebuilding the missing connections and bringing the board back to life.

WSON8 BIOS chips are a common headache — standard SOIC8 clips
often don't fit, and desoldering adds unnecessary risk to the board.
In this video I show a clean alternative: soldering temporary wires
directly to the chip pads and programming it in-circuit.

This method is useful when:
- A SOIC8 clip won't fit or gives unreliable contact
- The chip is awkward to desolder safely
- You want to avoid heat stress on surrounding components
- You need a stable connection for reading or writing

In this tutorial I cover the wiring setup, programmer configuration,
and precautions for safe in-circuit flashing.

Compatible with common WSON8 BIOS chips including Winbond,
GigaDevice, and Macronix series.

🔧 Tools used:
- CH341A Programmer
- NeoProgrammer / ASProgrammer
- Fine tip soldering iron
- Magnet wire / enamel wire

This technique works on laptop motherboards, desktop boards,
graphics cards, and any PCB where the BIOS chip is a WSON8
or similar flat no-lead package.

The failed USB-C Power Delivery controller in this Lenovo Yoga C930 laptop repair is a Cypress CYPD4226. After component replacement, the ultimate challenge became finding compatible firmware and restoring full USB-C and Thunderbolt functionality.

A Lenovo Yoga C930 came into the shop completely dead with a burned USB-C Power Delivery (PD) controller. Replacing the physical controller chip was only the beginning of this repair—the real challenge was restoring full system functionality without access to the original factory firmware.

In this video, I show the complete component-level diagnostic process, removal and micro-soldering replacement of the PD controller, testing with alternative firmware from a Lenovo Yoga C920, attempts to recover the original firmware using a CY8CKIT-059 programmer, and the hardware modifications required to restore charging, USB data functionality, and Thunderbolt support.

This is a real board-level repair journey including failed attempts, deep troubleshooting, and firmware investigation—not just a polished, final successful result.

Pioneer Kuro KRP-500A plasma TV stuck with the famous 8 blue lights fault? In this repair video I diagnose and repair the KRP-M01 media receiver board by replacing failed 1.8V regulators and reworking the DisplayPort IC area and nearby components.

This repair turned into a much larger job than expected because the KRP-M01 disassembly is a nightmare on its own, so the full teardown, diagnosis, board repair, reassembly and testing are included in the video.

The fault was causing the media receiver to fail startup with the 8 blue lights error. After replacing the faulty regulators and retouching the DP IC area, the system powers on normally again.

In this video:

This Acer TravelMate B3 school laptop came in completely dead. The NCP718 LDO regulator was getting extremely hot, making it look like the obvious fault — but the real problem turned out to be the USB-C PD controller IC.

In this laptop repair video, I walk you through the diagnostics, remove the shorted PD controller, and bring this budget laptop back to life. While we lost the USB-C port functionality, the laptop still charges perfectly fine using the old-style standard barrel connector!
