This page sets out the repairs, upgrades and data recovery we carry out on the LG Gram 14 14Z90N, with notes on what tends to go wrong and what can and cannot be upgraded. It is a 14-inch laptop from 2020. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Repairs we carry out on the LG Gram 14 14Z90N
Screen replacement
A broken 14-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
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 14Z90N 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
On most configurations of the LG Gram 14 14Z90N, 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 LG Gram 14 14Z90N 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. On a 2020 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
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 14Z90N, 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 14Z90N
The SSD in the LG Gram 14 14Z90N 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.
