Hardware Diagnosis Comes Before Hardware Replacement
We do not replace components simply because a symptom appears to point in one direction. The device is assessed to establish the likely cause before the appropriate repair route is recommended.
Hardware Faults We Can Investigate
Open a section below for more detail. Every section is closed initially.
Computer Will Not Switch On
A computer that appears completely dead can have several possible causes, including power delivery problems, a failed power supply, battery faults, charging faults, internal component failure or other electrical problems.
We assess the symptoms and determine the appropriate diagnostic route rather than assuming that the power supply or battery is automatically at fault.
Computer Shuts Down or Restarts
Unexpected shutdowns and restarts can be caused by overheating, unstable power, failing components, memory problems or other hardware faults.
Where the evidence indicates a physical hardware problem, we investigate the relevant components and operating conditions.
Overheating
Excessive temperatures can affect laptops, desktop PCs and workstations. Possible physical causes include restricted airflow, dust accumulation, cooling-system problems, failed fans or degraded thermal interfaces.
Temperature behaviour and cooling operation can be assessed as part of the diagnostic process.
Fan Problems
A failed, noisy or abnormal cooling fan can affect system temperatures and reliability.
We can assess fan operation and the surrounding cooling system to determine the appropriate repair route.
Display Problems
Blank screens, flickering, lines, unusual colours or intermittent displays can originate from the display assembly, cable, connector, graphics hardware or other physical components.
The device is assessed to distinguish a hardware display fault from a software or configuration problem.
Keyboard Problems
Individual keys, sections of a keyboard or an entire keyboard can fail because of physical damage, wear, contamination or other hardware faults.
Where applicable, the keyboard and its connections can be assessed.
Touchpad Problems
A laptop touchpad that stops responding or behaves incorrectly can have a physical fault involving the touchpad assembly, connection or surrounding hardware.
Software causes are considered separately where appropriate.
Charging Problems
A device that will not charge can have a faulty charger, charging port, battery, charging circuit or other related hardware issue.
The charging system is assessed to identify the likely source of the problem.
Battery Problems
Batteries naturally degrade with use. Physical battery faults can result in poor runtime, unexpected shutdowns, charging problems or other symptoms.
Swollen or physically damaged batteries require particular care and should not be posted or sent by courier.
Hard Drive Problems
Traditional mechanical hard drives can develop mechanical or electronic faults. Symptoms may include unusual noises, disappearing drives, read/write errors or system instability.
A failing drive should not be repeatedly stressed unnecessarily because this can affect the ability to recover accessible data.
SSD Problems
SSDs can fail or develop faults that result in drive detection problems, read/write errors, system instability or loss of access.
Where a storage fault is suspected, the condition of the drive is considered before replacement or migration work is recommended.
Memory Problems
Faulty or unstable RAM can cause crashes, freezes, boot problems and unpredictable behaviour.
Memory can be assessed as part of a hardware diagnostic where symptoms indicate a possible RAM-related fault.
Graphics Problems
Graphics hardware faults can produce display artefacts, crashes, black screens, instability or loss of display output.
The graphics subsystem can be assessed to determine whether the fault appears to originate from hardware or elsewhere in the system.
USB and Port Problems
USB ports and other physical connectors can become damaged, loose or unreliable through wear or physical impact.
We can assess supported ports and determine whether the fault appears to be physical or software-related.
Networking Hardware Problems
Wi-Fi, Ethernet and other network hardware can develop physical faults or connection problems.
Hardware diagnosis can help distinguish a failed physical network component from a software or configuration issue.
Physical Damage
Accidental drops, impacts and other physical incidents can damage screens, cases, ports, connectors and internal components.
The device is assessed to establish the extent of the physical damage and whether an appropriate repair is practical.
Liquid Damage
Liquid exposure can affect multiple internal components and may continue to cause corrosion or electrical problems after the initial incident.
Liquid-damaged devices require individual assessment. Liquid damage is not covered by the standard repair warranty.
Gaming Console Hardware Problems
Supported consoles can experience power, cooling, storage, display and connectivity faults.
We assess the console and symptoms before determining whether the fault can be addressed through supported hardware repair.
What We Check During Hardware Diagnosis
The diagnostic process depends on the device and symptoms, but the aim is always to establish the most likely physical cause before repair work is recommended.
| Diagnostic Area | What We May Investigate |
|---|---|
| Power | Power delivery, charging behaviour, batteries, power supplies and relevant physical connections. |
| Cooling | Fans, airflow, temperature behaviour and other physical cooling components. |
| Storage | Physical drive detection, drive health indicators and storage-related symptoms. |
| Memory | RAM installation, stability and symptoms associated with possible memory faults. |
| Display | Screen behaviour, physical display components, connections and relevant graphics hardware. |
| Connectivity | USB ports, charging ports, network hardware and other relevant physical connections. |
| Physical condition | Impact damage, broken components, damaged connectors and other visible physical faults. |
| Component behaviour | Whether individual physical components behave consistently with the reported symptoms. |
Hardware Repair or Component Replacement?
The appropriate solution depends on the component, device and fault identified during diagnosis.
Component Replacement
Where a supported component has failed and a suitable replacement is available, replacement may be the most appropriate repair route.
Hardware Upgrade
Some hardware faults can lead to an opportunity for an upgrade, such as replacing an older storage device with a suitable SSD.
Further Assessment
Some faults require additional investigation before a repair can be confirmed. We explain the appropriate route rather than guessing at the cause.
Our Hardware Repair Process
We work from the reported symptoms towards the physical cause of the fault.
Assess
We establish the symptoms, device condition and circumstances surrounding the fault.
Diagnose
We investigate the relevant physical components and determine the likely source of the problem.
Repair
Where an appropriate repair is available, the agreed hardware work is carried out.
Test
We check the repaired device to confirm that the relevant hardware fault has been addressed.
