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 17 17Z90S have two M.2 slots, so a second SSD can be added, or the existing one cloned to a larger drive.

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.
