Repairs we carry out on the ASUS ROG Strix Scar 18 G834
Screen replacement
We replace the 18-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.

Memory upgrade
Most configurations of the ASUS ROG Strix Scar 18 G834 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
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 Strix Scar 18 G834 shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Battery replacement
A new internal battery is fitted and tested through a full charge and discharge.

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.
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.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the ASUS ROG Strix Scar 18 G834, 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.
Known issues with the ROG Strix range
- Many ROG laptops from 2020 onward use liquid metal on the processor, which needs careful handling during a thermal service.
- Strix models usually have two memory slots and two M.2 slots, so upgrades are simple.

The SSD can be replaced, and most configurations have a second M.2 slot. Memory is in slots on most configurations and can be increased.
My ASUS ROG Strix Scar 18 G834 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.

Bring it to our workshop at Unit 1 The Willows, 80 Willow Walk, London SE1 5SY, or call 020 7237 6805 to ask about courier collection. We confirm the price before any work starts.
Why does my ASUS ROG Strix Scar 18 G834 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.
