At aGeek, we thrive on unravelling complex IT issues — whether it’s a faulty desktop or laptop, a phone or tablet, a games console, or a networking or software problem. We’ve got the tools, the experience, and the know-how.
Some diagnostics can be completed the same day, especially for straightforward issues, but our standard turnaround time is typically 3–5 working days, depending on workload and fault complexity. Please note: diagnostics can take up to 28 days in rare cases involving intermittent faults or where deep investigation is needed.
If you’re unsure what’s wrong, or if you’ve tried a DIY or failed repair attempt, our diagnostic service is the ideal starting point.
Trusted by Insurers and Banks
Unlike many local repairers who offer only a basic inspection, our diagnostics go far beyond “it’s probably the motherboard.” We carry out detailed component-level fault finding — the same level of inspection used by insurance companies and financial institutions to validate claims.
We identify the specific part that’s failed, such as a shorted capacitor, failed power rail, or memory controller, rather than replacing large and expensive parts blindly.
In most cases, we can even carry out board-level repairs, saving you the cost of complete replacements and reducing e-waste.

At aGeek in Chesterfield, we regularly see devices that have been brought to us after a failed DIY repair attempt. While we completely understand the satisfaction that comes with fixing something yourself (we are Geeks, after all!), there are some important reasons why DIY tech repairs often go wrong.
Here are some devices we have helped our DIY-ers repair:
PCs and custom desktops
Laptops (Windows, MacBook, Chromebook)
iPads and tablets
Mobile phones (iPhone, Samsung, and more)
Game consoles
And more…
Lack of Specialist Tools: Most consumer repair kits don’t include the precise tools needed for modern electronics like smartphones, tablets, laptops, or gaming consoles.
Poor Quality Parts: Cheap online components are often substandard, used, or even faulty straight out of the box.
Inexperience Leads to Damage: Without training, it’s easy to damage delicate connectors, strip screws, or crack screens during disassembly.
Warranty Risks: Attempting repairs on your own will usually void any manufacturer warranty — leaving you liable for the full replacement cost.
Leftover Screws or Missing Features: It’s frustrating to reassemble a device only to realise something no longer works properly or that you’ve got spare screws left over!
When you choose aGeek, you’re choosing experience, quality parts, and professional repairs that are done right the first time.
All Repairs Covered by Warranty: We offer up to 1-year warranty on most repairs — something no DIY repair can match.
Diagnostic Accuracy: We don’t guess. We diagnose faults down to the component level.
Fixed by Experts: Our skilled technicians use proper tools and proven methods to ensure your device is safe and functional.
Ongoing Support: If anything goes wrong with a repair, we’ll put it right under warranty, quickly and without hassle.
Before opening your device at home, consider whether it’s worth the risk. One wrong move can turn a minor repair into a major replacement. Bring it to aGeek — we’ll handle it with care and precision.
