I brought my out-of-warranty ASUS ROG Strix G16 with an RTX 4070 and Core i9 to a repair shop because the CPU was reaching about 96°C at idle and heavily thermal-throttling. The laptop still booted into Windows and was usable; the suspected cause was liquid-metal pump-out on the CPU die. I requested that the shop remove the existing thermal material and install Honeywell PTM7950 pads on both the CPU and GPU. The technician gave me an estimated labor cost of about $120.
After four days, the shop said that the laptop allegedly became stuck at the ASUS logo after the heatsink was removed and the pads were installed. They charged $125 for the thermal-pad service and another $75 diagnostic fee. Their invoice says that two inductors were not powering on and that multiple MOSFET controllers were shorted or failed. They now want $800–$1,200 for a replacement motherboard, or suggest buying another laptop.
The laptop worked before I brought it in, and the technician never asked for my Windows login, so they could not have verified my original idle temperatures. I am concerned that liquid metal may have been spilled, a tool may have slipped, or the battery may not have been disconnected during the repair. I also did not photograph the intake form, so I do not have a copy showing its original condition. What evidence should I gather, and what is the best way to dispute the charges or seek compensation if the shop caused the damage?

The invoice and timeline may help, but they do not automatically prove the shop caused the failure. A board can sometimes fail coincidentally, and a logo appearing on screen does not by itself establish which components failed. Ask for the original intake documentation and a detailed diagnostic report, then obtain an opinion from another qualified repair professional. Avoid opening or modifying the laptop yourself because that could make the evidence harder to preserve.
If the shop refuses to investigate or return the machine without payment, check your local consumer-protection rules and the terms on the repair authorization. You can send a concise written demand asking them to waive the service and diagnostic fees or pay for the documented damage. If that fails, a local small-claims or consumer complaint process may be an option. The likely outcome will depend on the intake form, any liability disclaimer, the shop’s records, and technical evidence linking the failure to their work.
Start by calmly speaking with the manager or owner rather than relying only on the technician’s explanation. Ask for a written account of the laptop’s condition when received, what procedures were performed, when it first failed, and the diagnostic results. Keep all texts, invoices, estimates, and call notes. Do not authorize a motherboard replacement until the responsibility issue is resolved, and consider getting an independent inspection with photos of any liquid-metal residue or physical damage.
That makes sense. I should focus on documenting the condition and getting an independent diagnosis instead of arguing only from the symptoms.
