Repairs we carry out on the ASUS ROG Zephyrus G15 GA502
Screen replacement
The 15.6-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
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.
Price confirmed before work starts
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 G15 GA502 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 G15 GA502, part of the memory is soldered and there is one free slot, so it can be increased but not replaced entirely.
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 G15 GA502 meets Microsoft’s Windows 11 requirements in most configurations. We upgrade from Windows 10, which reached end of support in October 2025, or reinstall Windows 11 cleanly with your files kept.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the ASUS ROG Zephyrus G15 GA502, 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.
What we see on the bench
- 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 G15 GA502

Questions
Can the SSD or memory in the ASUS ROG Zephyrus G15 GA502 be upgraded?
The SSD can be replaced with a larger M.2 drive. Part of the memory is soldered, with one slot free on most configurations.
My ASUS ROG Zephyrus G15 GA502 will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
Why does my ASUS ROG Zephyrus G15 GA502 overheat or slow down in games?
Usually dust in the heatsinks and thermal compound that has dried out. A thermal service fixes it in most cases. If temperatures are normal and it still slows down, we test the graphics chip and power delivery.
How much does a ASUS ROG Zephyrus G15 GA502 screen replacement cost?
Price confirmed before work starts. The exact figure depends on the part your machine needs, and we confirm it before any work starts.
