If your LG Gram Pro 16 16Z90SP has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. It is a 16-inch laptop from 2024. The SSD can be replaced but the memory is soldered, so storage is the only upgrade.

LG Gram Pro 16 16Z90SP repairs and upgrades
Screen replacement
A broken 16-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 Pro 16 16Z90SP have two M.2 slots, so a second SSD can be added, or the existing one cloned to a larger drive.

Memory
Memory in the LG Gram Pro 16 16Z90SP is soldered and cannot be upgraded. It is worth knowing this before paying anyone for a memory upgrade.
Windows repair and reinstall
The LG Gram Pro 16 16Z90SP shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Battery replacement
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load.
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 Pro 16 16Z90SP, 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 Pro 16 16Z90SP
The SSD in the LG Gram Pro 16 16Z90SP 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.
