Lenovo Legion Slim 7 15ACH6 repairs and upgrades
Screen replacement
We replace the 15.6-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
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
Most configurations of the Lenovo Legion Slim 7 15ACH6 have two M.2 slots, so a second SSD can be added, or the existing one cloned to a larger drive.
Price confirmed before work starts
Memory upgrade
Most configurations of the Lenovo Legion Slim 7 15ACH6 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 Lenovo Legion Slim 7 15ACH6 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.
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. A battery of this age that swells should be replaced before it damages the trackpad or casing.
Price confirmed before work starts
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 Lenovo Legion Slim 7 15ACH6, 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 Legion and LOQ range
- Hinge and lid problems were widely reported on 2020 and 2021 Legion 5 models.
- Legion machines respond well to a thermal service: fresh compound, new pads where needed, and clean fans.
- The graphics chip is soldered, so graphics faults are board-level repairs.
