ASUS ROG Zephyrus G16 GU603 Repair
We repair the ASUS ROG Zephyrus G16 GU603 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery.

Repairs we carry out on the ASUS ROG Zephyrus G16 GU603
Screen replacement
We replace the 16-inch panel with one that matches the original resolution and refresh rate. A cheaper 60Hz panel will physically fit many gaming laptops, and we do not fit one unless you ask for it.
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 G16 GU603 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
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 G16 GU603 takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.
Price confirmed before work starts
Memory upgrade
On most configurations of the ASUS ROG Zephyrus G16 GU603, part of the memory is soldered and there is one free slot, so it can be increased but not replaced entirely.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the ASUS ROG Zephyrus G16 GU603, 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.
Data recovery from the ASUS ROG Zephyrus G16 GU603
The SSD in the ASUS ROG Zephyrus G16 GU603 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start. Recent Windows machines often have device encryption or BitLocker switched on. If so we will need the recovery key, which is normally saved in your Microsoft account.
