Price confirmed before work starts
Windows repair and reinstall
The LG Gram 15 15Z990 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
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. A battery of this age that swells should be replaced before it damages the trackpad or casing.

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.
SSD and storage upgrade
Most configurations of the LG Gram 15 15Z990 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 15Z990, part of the memory is soldered and there is one free slot, so it can be increased but not replaced entirely.
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 15Z990, 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.
What we see on the bench
- 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 15Z990
The SSD in the LG Gram 15 15Z990 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.
