Emergency Spill Cleaning & Motherboard Repair

Accidents happen. If you’ve spilled coffee, water, or wine on your laptop, time is of the essence. Do not try to turn it on. Bring it to us immediately or call us out. We strip the machine down entirely and use professional ultrasonic cleaning and specialized solutions to remove corrosion, sugar residue, and moisture from the delicate circuitry. We then conduct component-level diagnostics to repair shorted micro-elements on the motherboard.

Overheating & Fan Service

Thermal Paste Replacement & Internal Deep Cleaning

Is your laptop fan constantly roaring like a jet engine? Is the bottom of the case burning hot to the touch? Over time, dust blocks the internal cooling vents, and the factory thermal paste dries up, causing the processor to overheat and throttle its speed. Our deep-cleaning service removes all internal dust, cleans the cooling fans, and replaces old thermal compound with premium, high-conductivity thermal paste to keep your machine running cool and quiet.

Hinge & Physical Case Repair

Structural Fixes for Broken Plastics and Loose Screens

Laptop hinges take a lot of stress over years of opening and closing. When a hinge stiffens or seizes up, it begins to tear away from the plastic or aluminum casing, cracking the screen bezel or separating the laptop body. We repair or replace damaged physical hinges and use specialized structural bonding techniques to reinforce or replace broken internal screw mounts, saving you the massive cost of buying a whole new chassis.

Laptop FAQ

Q: My laptop was splashed with water/coffee. What should I do immediately before bringing it in?

A: Turn it off instantly and unplug the charger. Do not try to turn it back on to “test” it, as this causes short circuits. Flip the laptop upside down like a tent to keep liquid away from the motherboard, and bring it to us as soon as possible. Avoid using rice, as it deposits dust and debris inside the components.

Q: How do I know if my laptop battery needs replacement or if it’s a charger problem?

A: If your laptop only works when plugged into the wall, or if Windows warns you with a “Service Battery” status, the battery likely needs replacement. If the laptop refuses to charge entirely, doesn’t light up when plugged in, or the charging cable feels loose inside the port, it is usually a faulty charging port (DC jack) or adapter.

: Can a cracked laptop screen be repaired, or does the entire display need to be replaced?

A: Modern laptop screens are sealed units, meaning the LCD or LED panel itself must be replaced if cracked or bleeding ink. However, we do not need to replace the entire top lid assembly or the housing—just the internal screen display panel, which keeps the repair highly affordable.

Q: Why is my laptop running extremely hot and making a loud buzzing noise?

A: This is usually caused by dust buildup blocking the cooling vents, or a failing internal cooling fan. When airflow is blocked, the thermal paste that transfers heat away from your processor dries out, causing the laptop to overheat and slow down to protect itself. A professional fan service and thermal paste replacement resolves this.

Q: Is it worth upgrading an older laptop, or should I just buy a new one?

A: If your laptop is less than 5 to 6 years old and has a solid chassis, upgrading from a mechanical hard drive to a Solid State Drive (SSD) and increasing the RAM can make it up to 5 times faster. This gives it a new lease on life for a fraction of the cost of buying a new machine.

Desktop PC & Gaming Computer FAQ

Q: My computer turns on, the fans spin, but there is no display on the monitor. What is wrong?

A: This common issue is usually caused by loose or dirty RAM modules, a failing power supply unit (PSU), or a faulty graphics card. Sometimes, it is as simple as the monitor cable being plugged into the motherboard’s video port instead of the dedicated graphics card port at the bottom of the tower.

Q: Why does my desktop PC randomly shut down or restart while I am gaming or working?

A: Random shutdowns under heavy workloads are almost always a safety measure triggered by component overheating (thermal throttling) or an unstable Power Supply Unit (PSU). Dust buildup in the CPU heatsink, dried thermal paste, or a graphics card drawing more power than the PSU can handle are the typical culprits.

Q: What is the difference between upgrading my RAM and upgrading my storage drive (SSD)?

A: Upgrading your RAM allows your computer to handle more tasks at the same time without slowing down, which is perfect for multitasking, gaming, and heavy web browsing. Upgrading to a Solid State Drive (SSD) improves the overall speed of the computer, making Windows boot up in seconds and causing apps and games to load instantly.

Q: My computer is making a clicking or loud grinding noise. Is it dangerous to keep using it?

A: Yes, you should back up your data and turn it off. A clicking noise usually indicates a mechanical hard drive is failing, which can lead to permanent data loss. A loud grinding or rattling noise is usually a failing cooling fan. While a bad fan won’t destroy data, it can cause components to overheat quickly.

Q: Can you build a custom desktop PC for gaming or office work if I provide the parts list?

A: Yes. We offer professional custom PC assembly services. Whether you want a high-performance gaming rig with liquid cooling and RGB lighting or a reliable, budget-friendly office workstation, we assemble the system, manage the cables cleanly, update the BIOS, install the operating system, and run stability tests.
