Polydarts Dart Machine Repair: No Schematics, No Manuals
A vintage Bulgarian electronic dart machine was stuck on a single game with zero documentation available. The fix was hidden deep inside the machine's own code.
Acer Predator 17 G9-793 Repair: Shut Down While Gaming Due to a Blown MOSFET
An Acer Predator 17 shut down mid-game and refused to turn back on. Instead of replacing the entire motherboard, we tracked down and replaced two faulty components.
We recently received an Acer Predator G9-793 for repair, a gaming laptop from the Predator 17 series. The owner told us the laptop abruptly shut off while gaming and wouldn't power back on. No warning, no overheating beforehand—it just died.
Why Do Acer Predator Laptops Shut Down While Gaming?
Gaming laptop power delivery circuits operate under intense load. The CPU and GPU draw significant current, especially during heavy gaming, causing the components along these power rails to wear out faster. When one fails, the laptop often cuts out right at peak load.
Two of the most common culprits are a blown MOSFET—a transistor regulating power delivery to specific areas of the board—and a shorted capacitor.
Motherboard Diagnostics
We started by checking the power rails one by one to isolate the fault. Once we found the problematic rail, we inspected the board with a thermal camera. By injecting power, the damaged component heats up and becomes clearly visible right away, without the need to desolder parts blindly.
That revealed two failed components:
A blown MOSFET on one of the power delivery rails.
A shorted capacitor on the same circuit.
How We Fixed the Motherboard
We replaced the MOSFET and capacitor with new matching components. This work is done at the component level using hot air and a microscope, ensuring neighboring parts are left untouched. After the swap, we re-tested all power rails.
The laptop powered right back on and runs properly once again.
Motherboard Repair vs. Board Replacement
Many repair shops simply suggest replacing the entire motherboard. For an Acer Predator 17, a new board is expensive and often difficult to source, especially for older models. Component-level repair resolves the issue at a fraction of the cost while keeping the laptop's original board intact. That’s why we always troubleshoot down to the individual component first.
Gaming Laptop Repair
We repair laptops, phones, and consoles at the component level at our workshop on 34 Targovska St. in Gotse Delchev. We also accept devices from all across Bulgaria via Econt and Speedy. Read about how we repaired a vintage dart machine without any schematics or documentation.
