If your LG Gram 14 14Z90S has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. The LG Gram 14 14Z90S is a 2024 laptop with a 14-inch screen. The SSD can be replaced but the memory is soldered, so storage is the only upgrade.

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.
SSD and storage upgrade
Most configurations of the LG Gram 14 14Z90S 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
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 LG Gram 14 14Z90S, 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
- Most Gram models have two M.2 slots, so adding storage is simple.
- The Gram’s very light magnesium alloy chassis flexes more than most, and the display is easily damaged by pressure on the lid.
Data recovery from the LG Gram 14 14Z90S
The SSD in the LG Gram 14 14Z90S 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.
