Hardware failure doesn't mean the end of your laptop. Whether it's a grinding fan, a screen that won't stay up, or a motherboard that won't post, JTG Systems stocks thousands of parts to bring your device back to life.
TEXT is best. Are you looking for Laptop Hardware Repair? You found it! Let's get to work on your device right away—bring it in and our experienced team will start the repair while you wait.
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 component-level repair, meaning we replace the specific broken part (like a capacitor or a fan) rather than forcing you to buy a whole new expensive motherboard whenever possible.
We stock parts for Dell, HP, Lenovo, Acer, ASUS, and Apple.
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 blow capacitors on the main logic board. We diagnose these component-level faults.
| Symptom | Likely Component | Recommended Fix |
|---|---|---|
| Loud Grinding Noise | Failing Fan Bearing | Fan ReplacementThe cooling fan mechanism is worn out. Continued use will lead to overheating. |
| Laptop Gets Extremely Hot | Dried Thermal Paste | Thermal ServiceThe conductive paste between CPU and Heatsink is dry. We clean and apply fresh Arctic Silver paste. |
| Screen Flickers when Moved | Damaged LVDS/eDP Cable | Cable ReplacementThe video cable running through the hinge is pinched or frayed. |
| Beeping on Startup | RAM Error or Stuck Key | Diagnostics RequiredBIOS beep codes indicate specific hardware failures. Count the beeps and tell us! |
* This is a general guide. An in-person evaluation is required for a guaranteed diagnosis.
A professional repair is better than a premium new laptop. Trust Niagara's hardware experts to extend the life of your device.
