Hardware issues generally fall into two categories: Wear & Tear (fans, hinges, batteries) and Catastrophic Failure (drops, spills, surges). Unlike software bugs, these problems won't go away with a reboot.
We provide module-level repair, meaning we replace the specific broken part (like a fan, battery, or port) rather than forcing you to buy a whole new expensive motherboard whenever possible.
Most parts for Dell, HP, Lenovo, Acer, ASUS, and Apple arrive within 1-2 business days.
The plastic mounting points inside the chassis snap, causing the screen to separate from the base.
Dust clogs the heat sink, or the thermal paste dries out, causing the CPU to throttle or the laptop to shut down.
Physical impact or closing the lid on an object shatters the internal LCD panel requiring replacement.
Slow boot times, freezing, or 'No Boot Device' errors often mean your storage drive is failing.
If Wi-Fi drops or is weak, the internal antenna cables may be disconnected or the NIC card has failed.
Liquid damage or power surges can damage the main logic board. We diagnose these faults and advise on module replacement or board-level referral.

|---|---|---|
| Loud Grinding Noise | Failing Fan Bearing | Fan ReplacementThe cooling fan mechanism is worn out. Continued use will lead to overheating. |
