The LG Gram SuperSlim is the thinnest machine in LG's laptop range, pushing the Gram design philosophy to its limit in terms of weight and chassis depth. The SuperSlim is built for maximum portability and relies entirely on USB-C and Thunderbolt for charging, display output, and connectivity. The extremely thin chassis leaves minimal thermal headroom, making the machine more sensitive to thermal paste degradation and sustained workloads than any other Gram model.
Brentworth reviews Gram SuperSlim mail-in repair requests for the faults that thin premium laptops develop: port wear, display cable stress, battery swelling, thermal throttling, liquid damage, and board-level no-power conditions.

The Gram SuperSlim relies entirely on USB-C for charging and connectivity. With no alternative charging port, a worn or failed USB-C port leaves the machine unable to charge at all. Ports used daily with adapters, hubs, and cables develop mechanical wear that causes intermittent contact before failing entirely. A port that only charges at certain angles should be assessed promptly.
The SuperSlim chassis has the most constrained thermal envelope of any Gram model. Sustained workloads — video calls with screen sharing, document processing with background tasks, or any creative work — can cause temperatures to rise faster than on other Gram machines. Thermal paste degradation over time reduces what little headroom exists.
SuperSlim batteries are designed to fit an extremely thin chassis, leaving virtually no room for expansion. Even a modest amount of swelling can crack the bottom panel, damage the keyboard assembly, or put pressure on the display. A SuperSlim with any sign of swelling — raised bottom panel, keyboard flex, or a lid that no longer closes flat — should be assessed immediately.
Display cables in ultra-thin chassis are routed in very tight paths with minimal slack. Repeated opening and closing causes stress damage that develops into flickering, color shift, or a display that only works at certain lid angles. The fault is more likely to develop sooner on extremely thin machines than on thicker hardware.
An ultra-thin chassis means liquid reaching the keyboard has almost no internal structure to slow it before it contacts the board. A spill that seems minor on a thicker machine can reach critical components almost immediately on a SuperSlim. Do not power on the machine after any liquid exposure — shut it down, disconnect power, and submit intake.
A SuperSlim that will not respond to the power button despite a connected adapter may have a worn USB-C port, a depleted or swollen battery, or a board-level power fault. With no alternative charging input, a failed USB-C port completely prevents charging. No sign of life after an extended charge period with a confirmed-working adapter requires board-level diagnosis.
Yes. USB-C port faults on the SuperSlim are reviewed at intake. With no alternative charging input, a failed USB-C port prevents the machine from charging entirely. Diagnosis checks the port, the charging circuitry, and the board before any repair is quoted.
Very urgent. The SuperSlim chassis leaves virtually no room for battery expansion. Any sign of swelling — a raised bottom panel, keyboard that feels different, or a lid that no longer closes flat — means the battery needs to be assessed and replaced as soon as possible. Do not continue using the machine and submit intake immediately.
Yes. The SuperSlim has the most constrained thermal envelope of any Gram model. Throttling during tasks that other laptops handle without issue is not unusual, but if it has become worse than before, thermal paste degradation is the most likely cause. A thermal service is the starting point.
Position-dependent display behavior almost always points to a display cable fault at the hinge. The cable flexes with every open and close cycle and eventually develops stress damage. In ultra-thin chassis the cable has less slack and is more likely to develop stress faults earlier than on thicker machines.
Yes. Liquid damage on SuperSlim hardware is reviewed at intake. The extremely thin chassis means liquid reaches the board faster than on any other Gram model. Do not power on the machine after liquid exposure before it has been inspected. Submit intake immediately.
Yes. Screen replacement on the Gram SuperSlim is reviewed at intake. Ultra-thin display assemblies may have longer sourcing lead times than panels from established product lines. Include the exact model so the correct panel can be confirmed.
Yes. No-power faults on SuperSlim hardware are reviewed at intake. Describe any sign of life — indicator lights, brief fan activity, or screen flicker — and include the exact model. With only USB-C charging available, a failed port and a board-level fault can present identically from the outside.
Yes. Battery replacement on the SuperSlim is reviewed at intake. The extremely thin chassis makes battery work more involved than on standard Gram models. Include the exact model so the correct replacement can be sourced and the repair scope can be assessed.
