If your ASUS ROG Zephyrus G14 GA403 has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. It is a 14-inch gaming laptop from 2024. The SSD can be replaced but the memory is soldered, so storage is the only upgrade.

ASUS ROG Zephyrus G14 GA403 repairs and upgrades
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
Overheating and fan repair
We strip the cooling system, clean the fans and heatsink fins and renew the thermal compound and pads. We check temperatures under load afterwards.
SSD and storage upgrade
The ASUS ROG Zephyrus G14 GA403 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 GA403 is soldered and cannot be upgraded. It is worth knowing this before paying anyone for a memory upgrade.
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 GA403 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
Depending on the configuration this charges through a round socket, USB-C or both. We test the adapter, the port and the charging circuit to find which has failed.
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 GA403, 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
- 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.
- 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.
