This page sets out the repairs, upgrades and data recovery we carry out on the Lenovo Legion 5 15ARH05, with notes on what tends to go wrong and what can and cannot be upgraded. It is a 15.6-inch gaming laptop from 2020. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

What we repair on the Lenovo Legion 5 15ARH05
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
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
Most configurations of the Lenovo Legion 5 15ARH05 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 5 15ARH05 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 5 15ARH05 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
A new internal battery is fitted and tested through a full charge and discharge. A battery of this age that swells should be replaced before it damages the trackpad or casing.
Price confirmed before work starts
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the Lenovo Legion 5 15ARH05, 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
- 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.
Data recovery from the Lenovo Legion 5 15ARH05
The SSD in the Lenovo Legion 5 15ARH05 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.
