Professional tech maintenance: How CompX restores laptops and PCs to full functionality

A modern laptop or PC requires careful maintenance – any mistake can lead to failure. That’s why CompX offers professional equipment repair and maintenance services, from BIOS password resets to comprehensive video card cleaning. Below are the three most popular procedures that extend the lifespan of devices and restore their stable operation.

Unlocking and resetting the BIOS password

A BIOS password is important protection, but if forgotten, a laptop becomes useless. CompX specialists unlock all popular models – HP, Dell, Lenovo, Acer, Asus, and others.

Before starting, the engineer runs diagnostics: determines the security type (System or Admin), the BIOS version, and the presence of a manufacturer master password. After this, a reset method is selected:

• Hardware method – removing the CMOS battery or adjusting the jumper on the board;
• Software method – using a special master code or programmer;
• Full BIOS recovery – flashing the original dump and verifying serial data (UUID, MAC addresses, serial number).

This procedure does not affect the drive or the operating system. After unlocking, the BIOS is reset to its factory state, and the system is tested for boot stability, boot mode (Legacy/UEFI), and correct parameters. The work takes 1-2 days and is guaranteed.

Video Card Maintenance and Service

FPS drops in games, overheating, and fan noise are typical signs that the cooling system is clogged with dust. CompX provides full graphics card maintenance, including:

• heatsink and cooler disassembly;
• pressurized air blowing and cleaning;
• thermal paste replacement;
• microscopic inspection of solder joints and capacitors;
• temperature testing under load after assembly.

Cleaning restores normal thermal conditions, reduces noise, and extends the life of the graphics card. It is especially important to perform this procedure every 6-8 months during active use or in hot climates.

Full Maintenance

Even the most expensive system unit requires regular maintenance. CompX offers a "Full Maintenance" service package, which includes:

• cleaning the motherboard, heatsinks, and power supplies from dust and plaque;
• lubricating and cleaning fans, restoring their speed;
• replacing thermal paste and thermal pads on the processor, graphics card, and VRM areas;
• checking temperature sensors and noise levels.

Before cleaning, temperatures are measured at idle and under load, and a control stress test is performed afterwards. If thermal pad wear is detected, replacements of the correct thickness and thermal conductivity are selected.

It is recommended to perform this maintenance at least once a year, and every 6 months if the computer operates in a dusty environment. This helps prevent overheating and premature component failure.

CompX operates officially, guarantees all service work, and maintains factory settings for the equipment. Service acceptance is carried out at offline locations in Kyiv and with delivery throughout Ukraine. Thanks to accurate diagnostics and a proven service process, customers receive a fully restored device, ready for stable operation.
