Computer repair advice and case studies from our engineers

We fix a lot of computers. Most jobs are straightforward – cracked screen, overheating fan, laptop that won’t turn on. But some are genuinely interesting, and a few teach us something we didn’t expect.

This is where we write about it. Real repairs we’ve done, problems we see regularly, and practical advice for anyone trying to work out what’s wrong with their machine before picking up the phone. No padding, no “in today’s digital world” nonsense – just the stuff that’s actually useful.

This is the right time to replace the battery

If your laptop battery now dies quickly, charges slowly or shuts down without warning, it can be hard to tell whether the battery is worn out or something else is wrong. This guide explains the signs to look for, when it becomes a safety issue, and what battery replacement in the UK usually depends on before you decide whether to repair the laptop or replace it.

On-site vs workshop motherboard repair

If you think the motherboard may be at fault, an engineer can often check the basics at your home or workplace first. But the actual repair or replacement has to be done in a workshop, and this article explains why – along with what can still be fixed on site across London.

Cost, time, and warranty of motherboard repairs

When a motherboard fault is suspected, most people need the same answers quickly – what the repair actually involves, what it might cost, how long it could take, and whether it is likely to last. This article explains the factors that affect motherboard repair so you can judge whether it is worth doing before you commit.

Mac motherboard repair vs Windows motherboard repair

If your computer will not turn on, keeps crashing, or has charging problems, the fault may be on the motherboard – but Mac and Windows repairs are not handled in the same way. This article explains what differs, what might be repairable at component level, and what affects cost, time, and whether the repair is worth doing.

Repair or replace – making the right decision

If your computer has failed and you need it back quickly, the hardest part is often knowing whether a repair still makes financial sense. This guide walks through how to weigh up cost, downtime, data safety, and what happens if a motherboard repair does not work out.

Laptop overheating and cooling problems explained

A laptop running hot does not always mean something serious, but constant fan noise, sudden shutdowns, or a case that feels far too hot usually point to a cooling issue. This guide explains in plain English how laptop cooling works, what commonly goes wrong, and when a clean-out or parts replacement may be needed.

Common laptop problems explained – symptoms, causes, solutions

Most laptop problems start with a symptom – slow performance, strange noises, charging issues, crashes – but the cause is not always obvious. This article explains what those signs usually point to, separates hardware faults from software issues in plain English, and shows when the same problem needs a proper diagnosis before anyone can say what repair is needed.

Liquid and physical damage to motherboards

If your laptop was soaked or took a hard knock, the motherboard may still be repairable – but not always. This article explains what engineers look for after liquid spills, corrosion, or impact damage, and where the line is between a sensible repair and money wasted.

BIOS and firmware related motherboard repairs

If your computer freezes on the logo screen, cannot find the drive, or stopped working after an update, the fault may be in the BIOS or firmware rather than a completely dead motherboard. This article explains how these faults are diagnosed, what BIOS reprogramming involves, and why some repairs can be done on-site while others need workshop bench work.

Random crashes, freezes, and instability

If your computer turns on but keeps freezing, crashing, restarting or losing things like USB and audio, the fault is not always obvious. This article explains why these problems can point to a motherboard issue rather than a power fault, and why proper checks matter before anyone can give a clear idea of cost or repair time.

How often should computers be cleaned and repasted

Most people only think about this when a computer starts running hot, getting noisy or slowing down, but the right cleaning and repasting interval depends on how and where it is used. This guide breaks it down in plain English for home users, office PCs, gaming machines and dustier spaces, so you can judge when simple maintenance is due and when it is worth booking a professional service.

Charging and power circuit faults on motherboards

If your laptop will not charge, only works on the mains, or has gone completely dead, the cause is not always the battery. This article explains the common power faults behind those symptoms, what proper testing needs, and why some checks can be done quickly while motherboard repair usually depends on workshop diagnosis.

Desktop PC dust cleaning and repasting – how it differs from laptops

If your desktop has started running hot, sounding louder than usual, or crashing under load, dust cleaning and repasting may help – but it is not quite as simple as blasting it out with compressed air. This guide explains what gets cleaned, what can be repasted, why graphics card work is a separate job, and where the real risks, time, and cost tend to come in.

DIY laptop cleaning – what is safe and what is risky

If your laptop is dusty, noisy or running hot, it is tempting to clean it yourself – but some common methods can do more harm than good. This guide explains what you can safely clean from the outside, which tips are risky, and when it is better to let a repair engineer handle the inside.

Gaming laptops and workstations – cleaning and repasting intervals

If your gaming laptop or workstation only gets hot, loud, or slow when it is under heavy use, that usually points to cooling maintenance rather than a mystery fault. This article explains, in plain English, when cleaning and repasting are worth doing, why high-load machines need it sooner than ordinary PCs, and what sort of improvement you can realistically expect.

No power and no boot issues – motherboard causes

Not sure if it’s a dead board or something simpler? It is often not the motherboard. This guide covers the real causes of no power and no boot – from shorted rails and liquid damage to charger faults and USB-C negotiation failures – and how a proper diagnosis tells them apart.
