We repair the LG Gram 15 15Z90N at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. The LG Gram 15 15Z90N is a 2020 laptop with a 15.6-inch screen. 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 15 15Z90N
Screen replacement
We replace the 15.6-inch panel like-for-like, matching resolution and connector to the part number on the original.
Price confirmed before work starts
Battery replacement
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. 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
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 15 15Z90N 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 15 15Z90N, 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 15 15Z90N 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.
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 15 15Z90N, 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 15 15Z90N
The SSD in the LG Gram 15 15Z90N 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.

Questions
Can the SSD or memory in the LG Gram 15 15Z90N be upgraded?
The SSD can be replaced, and most configurations have a second M.2 slot. Part of the memory is soldered, with one slot free on most configurations.
My LG Gram 15 15Z90N will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
How much does a LG Gram 15 15Z90N screen replacement cost?
Price confirmed before work starts. The exact figure depends on the part your machine needs, and we confirm it before any work starts.
Is a 2020 LG Gram 15 15Z90N still worth repairing?
It depends on the fault. A battery, SSD or charging socket is usually worth doing. A major board repair on an older machine may cost more than the machine is worth, and if that is the case we will say so.
