Five laptop problems we fix every week, and what they’re actually costing you

A laptop that won’t charge isn’t necessarily dying. A MacBook with a black screen isn’t necessarily totalled. A spilled coffee isn’t necessarily the end. Here are the five problems we see most often on the bench, what’s almost certainly going on, and what a fair repair should look like.

1. “It won’t charge.”

This is our number-one inquiry. About 70% of the time it’s a worn battery or a damaged charge port, both are inexpensive, common parts. The remaining 30% is a board-level issue (a blown charging IC, a damaged trace) which is more serious but, in our shop, still fixable.

What you should expect: a free diagnosis to figure out which of those it is, a written quote before any work, and a battery or port replacement that runs $59–$129 on most models. Board-level work is quoted individually.

2. “It won’t turn on at all.”

A dead laptop is scarier than a dying one because it gives no clues. On the bench, our first move is to check whether the board is taking power. If it is, we move up the chain to display and graphics. If it isn’t, we’re into board-level diagnostics.

About half the “no power” laptops we open have a simple fix, a failed charge IC, a corroded power filter, a single bad capacitor. Board-level repair sounds dramatic; on a healthy machine that just had one component fail, it’s often the cheapest path back to a working computer.

Not sure which of these your machine has? Bring it to the bench in Courtice for a free diagnosis, we do board-level laptop and MacBook work in-house, and you get a written quote before anything is touched.

3. Cracked screen or backlight gone

Laptop screens are usually replaceable as a unit. Windows laptops are typically straightforward, pop the bezel, swap the panel. MacBooks are more involved on modern models because Apple sells the display as a complete top-case assembly, so a full screen replacement is a bigger job.

If the picture is there but the backlight is gone, it might be a fuse or LCD cable, a $40 part. Always ask for a backlight test before agreeing to a full panel.

4. Loud fans, sluggish performance, random shutdowns

Nine times out of ten this is heat, dust-clogged cooling, dried-out thermal paste, or a fan that’s started to fail. Symptoms feel like a dying computer; the fix is usually closer to “spa day.”

A proper thermal service means opening the machine, cleaning the heatsink, replacing the thermal paste with a quality compound, and verifying temperatures under load. Most shops we know charge $89–$129 for this and the machine often comes back feeling 2–3 years younger.

5. Liquid spill

A spilled drink is the most time-sensitive of the five. Power off immediately, unplug, do not turn it back on to “see if it still works”, that’s what kills boards.

On the bench: we open it, disassemble the board, ultrasonic-clean every component, and then power it up under controlled conditions to see what survived. Most spills, caught early, are fully recoverable. Recovery work is no-fix / no-fee at our shop, if we can’t bring it back, you don’t pay for the diagnostic time.

When it’s genuinely time to replace

A repair is rarely the wrong call on a machine you like, but there are honest “replace it” moments:

• The repair quote is more than 60% of a replacement of equivalent specs.
• The machine is more than 7 years old and you rely on it daily for work.
• macOS or Windows no longer supports the hardware and updates have stopped.
• It has a structural problem (hinges, bent chassis) on top of the electrical one.

If you bring a laptop in and the honest answer is “replace it,” we will say so. That’s the whole point of a free diagnosis.
