Eight Laptop Warning Signs Pembrokeshire Owners Shouldn't Ignore — and What Repairs Really Cost

Why a laptop MOT is worth 30 minutes of your time

Most laptops don't fail without warning. They give you clues for weeks — a noise here, a hot patch there, a battery that suddenly won't last the morning. The trick is knowing which clues mean "book a repair" and which mean "start shopping". Here are the eight we see most often at our Pembroke workshop, with honest price ranges for the local area in November 2026. Prices include parts and labour for common models; always ask for a written quote before authorising work.

1. The fan sounds like a light aircraft

What it usually means: Dust has clogged the heatsink, the fan bearing is worn, or both. Ignore it and the laptop will start throttling — running slowly to protect itself from heat — and may shut down without warning.

Typical local cost: £35-£75 for a replacement fan, plus £30-£50 labour. A full clean and thermal repaste is usually £50-£80 and sorts most noise problems. Worth fixing on almost any laptop that's otherwise sound.

2. The trackpad is bulging, or the case won't sit flat

What it usually means: A swollen lithium-ion battery. This is the one sign you shouldn't ignore for a single day. Swollen batteries can damage the trackpad, keyboard and case, and in rare cases they're a fire risk.

Typical local cost: £40-£90 for a common battery, plus £25-£45 labour. On some thin laptops the battery is glued in, which pushes the job to £100-£150. Stop using it on your lap or overnight while you wait for the repair.

3. Boot times longer than the queue at Tesco

What it usually means: A failing mechanical hard drive, too little RAM, or a Windows installation that's grown fat with startup apps. If the laptop is more than five years old and still has a spinning hard drive, this is almost certainly the culprit.

Typical local cost: £35-£70 for an SSD, plus £40-£70 labour including cloning your old drive. A RAM upgrade to 8GB is £25-£60. This is usually the best money you can spend on an older machine — it can feel like a new laptop for under £120.

4. It's hot enough to fry an egg

What it usually means: The same dust problem as the noisy fan, or dried-out thermal paste between the processor and heatsink. It might also be sitting on a duvet or cushion, blocking the vents.

Typical local cost: £50-£85 for a clean and repaste. If the heatsink itself is damaged, expect £100 or more. Try it on a hard, flat surface first — it costs nothing and sometimes solves the problem entirely.

5. The hinge is cracking the screen bezel

What it usually means: The hinge has seized or the plastic mounting points have broken. Keep opening and closing it and you'll soon be replacing the screen as well.

Typical local cost: £70-£150 for a hinge repair. If the bezel or screen mounting is already cracked, it can be more. On budget laptops, this is often the point where a repair stops making financial sense — get a quote before you commit.

6. Random shutdowns or blue screens

What it usually means: Could be RAM, overheating, a failing drive, a driver problem or the motherboard. This is the one fault that genuinely needs diagnosis rather than guesswork.

Typical local cost: £25-£40 for a diagnostic, often deducted from the repair if you go ahead. New RAM is £30-£60. Motherboard repair is £150+, and a replacement board is frequently uneconomic. Back up your files before you do anything else.

7. Keyboard keys stop registering

What it usually means: Spilled liquid, worn contacts or a failed keyboard membrane. Sometimes a single key is sticky; sometimes a whole row is dead.

Typical local cost: £25-£60 for the keyboard part, plus £30-£60 labour. On some models the keyboard is built into the top case, which pushes the job to £80-£180. If you mostly use it at a desk, a £15 USB keyboard is a perfectly sensible stopgap.

8. Wi-Fi drops every few minutes

What it usually means: A failing Wi-Fi card, an outdated driver, or interference from the router. Try moving closer to the router and updating the driver before you book anything.

Typical local cost: A USB Wi-Fi dongle is £15-£25 and often fixes the problem outright. An internal card is £15-£40 plus £30-£50 labour. If the laptop is otherwise fine, this is an easy and worthwhile fix.

What a diagnostic should cost

Most independent shops in the Pembroke area charge £20-£40 for a laptop assessment. Ask two questions before you hand over the machine: is the fee deducted from the repair if you go ahead, and will you get a written quote before any work starts? A good shop will happily answer both.

The £200 rule

As a rough guide, if a repair costs more than half the price of a comparable refurbished laptop, think carefully. A decent refurbished business laptop with an Intel i5, 8GB RAM and a 256GB SSD is typically £180-£300 in 2026. Spending £250 repairing a seven-year-old budget model rarely makes sense. Spending £80 on a new SSD and fan clean for a solid machine absolutely does.

Local drop-off and recycling

If you're in Pembroke, Pembroke Dock, Tenby, Haverfordwest or Milford Haven, most repairs can be done while you wait or within a couple of days. Ask whether the shop offers a loan laptop for longer jobs. And if the machine is beyond economic repair, don't bin it — Pembrokeshire County Council's recycling centres accept small electricals, and any reputable repair shop will wipe the drive before recycling. At Pembroke PC Doctor we're happy to give you a straight answer, even if that answer is "don't spend money on this one".
