What we repair on the ASUS ROG Zephyrus G14 GU405
Screen replacement
The 14-inch panel is matched to the original by part number, including refresh rate and connector type, so games run as they did before.
Price confirmed before work starts
Graphics repair
The graphics chip is soldered to the board. Artefacts, crashes under load and a black screen with the fans running are diagnosed to the chip, its memory or its power stage, and repaired at board level where it is economical.
Windows repair and reinstall
The ASUS ROG Zephyrus G14 GU405 shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time.

Charging port and power repair
We replace worn charging sockets and repair USB-C ports and charging circuits at component level. The adapter is tested first, because it is the cheapest thing to be wrong.
Overheating and fan repair
A thermal service covers fresh compound on the processor and graphics chip, new thermal pads where needed and both fans cleaned. It is the usual cure for throttling and loud fans under load.
SSD and storage upgrade
The ASUS ROG Zephyrus G14 GU405 takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.

Memory
Memory in the ASUS ROG Zephyrus G14 GU405 is soldered and cannot be upgraded. It is worth knowing this before paying anyone for a memory upgrade.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the ASUS ROG Zephyrus G14 GU405, along with USB, HDMI and audio port repair, Wi-Fi and Bluetooth card replacement, webcam and speaker faults, BIOS password removal with proof of ownership and data transfer to a new machine.
Notes from the workshop
- Many ROG laptops from 2020 onward use liquid metal on the processor. A thermal service on these needs the right materials and barriers, or it does more harm than good.
- The Zephyrus G14 and G15 have one soldered memory module and one slot on most generations.
- The graphics chip is soldered, so graphics faults are board-level repairs.
