The MSI Stealth 18 HX AI from 2025 (18" Gaming Laptop) is one of the newest machines through our bench — modern thermals, thin-film batteries, and Type-C charging that all behave differently to repair than older platforms. Common faults on gaming laptops like the Stealth: thermal paste degradation causing throttling, fan bearing wear, and GPU memory faults. Repaste + fan replacement is a 24h job that brings most rigs back to factory-spec thermals. Free written diagnostic on every booking, fixed-price quote in 24 hours, 12-month warranty on the part and the labour.
What this fix covers.
If you brought your Stealth 18 HX AI in for battery replacement, here’s what we’ll do, in order:
- Diagnostic — free, written, with photos. We confirm the fault is what you think it is before we touch anything.
- Fixed-price quote — from from £69, no creep. If we find a second issue underneath, we ring you before doing anything.
- Repair on the bench — OEM or OEM-equivalent parts, ESD-protected, magnification where needed. Same day turnaround on most jobs.
- Bench-test & return — we run the symptom you brought it in for, plus a full system check, before it leaves the shop. 12 months warranty on the part and the labour.
