Repairs we carry out on the Lenovo ThinkBook 15 G3 ACL
Screen replacement
A broken 15.6-inch screen is replaced with a panel of the same resolution and finish. We check the display cable while the lid is open.
Price confirmed before work starts
SSD and storage upgrade
The Lenovo ThinkBook 15 G3 ACL 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 Lenovo ThinkBook 15 G3 ACL, part of the memory is soldered and there is one free slot, so it can be increased but not replaced entirely.
Windows repair and reinstall
The Lenovo ThinkBook 15 G3 ACL 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. On a 2021 machine a worn battery is the likely cause of short runtime, and we measure its capacity before recommending anything else.
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.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the Lenovo ThinkBook 15 G3 ACL, 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
- USB-C charging faults are the common board repair.
- ThinkBooks combine consumer-style chassis with business features; most have a replaceable SSD, and memory is part-soldered on many.
Data recovery from the Lenovo ThinkBook 15 G3 ACL
The SSD in the Lenovo ThinkBook 15 G3 ACL 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.
