We supply computer hardware, and we repair almost anything with a CPU, from mobile phones to large server infrastructure.
When a critical computer, smartphone, or server fails, many repair outlets will tell you that it cannot be repaired. Instead, they encourage you to purchase an expensive replacement, often leaving you without your data or essential tools while waiting for new stock to arrive.
Prometheus Systems takes a different approach. We are professional systems architects and hardware engineers who design, service, and repair a wide range of computing platforms. From everyday laptops and smartphones to enterprise server infrastructure and specialist UNIX workstations, we repair equipment that others consider beyond recovery. We diagnose complex hardware faults, replace failed components, and restore systems to reliable working condition.
- No Job Too Complex: We work across the entire computing spectrum. Our team supports consumer electronics, high-performance gaming systems, business workstation fleets, and specialised legacy platforms.
- Transparent Local Service: No hidden costs or unnecessary jargon. We provide clear assessments, dependable turnaround times, and direct communication with the engineer working on your equipment.

What We Do For You
Whether you are an individual looking to save an expensive personal device or an IT manager responsible for keeping your organisation online, we provide specialised support across three core service areas:
- Smartphones, Tablets, and Laptops: Fast, dependable repairs for the devices you rely on every day. We handle cracked screen replacements, battery failures, charging port repairs, broken hinges, and liquid damage remediation.
- Custom PC Builds and Upgrades: Bespoke desktop systems designed for gaming, content creation, engineering workloads, or office productivity. We can also breathe new life into existing computers with high-speed solid-state drive (SSD) upgrades and memory expansions.
- Servers, Networks, and Workstations: Specialist maintenance for business infrastructure. We service rack-mounted servers, multi-drive storage arrays, and legacy UNIX workstations, including platforms such as Sun SPARC, Silicon Graphics, and IBM POWER.
Real Engineering, Not Guesswork
Every repair is approached with technical discipline and methodical diagnostics. Your equipment is handled in an ESD-safe environment using professional engineering procedures.
- Advanced Thermal Servicing: Excessive heat shortens component lifespan and reduces performance. We completely disassemble ageing systems, remove dust build-up, and apply high-quality thermal compounds to restore efficient cooling.
- Data Recovery Assistance: If a device no longer powers on, we can often perform emergency board stabilisation procedures to safely recover valuable family photographs, business records, and other irreplaceable data.
- Comprehensive Bench Testing: We do not return equipment simply because it powers on. Every repaired device undergoes extensive stress testing to confirm long-term stability under demanding workloads.
