You press the power button. Nothing. You press it again, harder this time, as if that ever helps. Still nothing.
And of course it’s the morning you needed it. The work report, the uni deadline, the family photos you never got round to backing up.
Take a breath. A laptop that won’t turn on is one of the most common things people bring through our door on Oldham Road, and a lot of the time it’s fixable. Sometimes it’s not even broken. This guide walks you through the checks worth trying at home, the usual causes, what happens to your files, and how to decide whether a repair is worth the money or whether it’s time to move on.
The short answer
Before you assume the worst, check the socket, the charger and the cable, unplug everything else, and hold the power button down for longer than feels normal. That sorts out more “dead” laptops than you’d think.
If it still won’t come on, the cause is usually one of a handful of things: a failed charger, a worn charging socket, a dead battery, liquid damage, a screen that has stopped showing anything, or a fault on the main board. Most of these can be repaired. Whether you should repair it depends on the laptop’s age, what the fault turns out to be, and what the repair costs compared with replacing it. And if the numbers don’t stack up, we also buy laptops and MacBooks, including faulty ones, so a dead laptop isn’t necessarily worthless.
First, what does “won’t turn on” actually look like?
People say “it won’t turn on” about quite different problems, and the difference matters. Before you do anything else, watch the laptop closely when you press the power button. Which of these sounds like yours?
- Completely dead. No lights, no fan, no sound, nothing on the screen. This points towards power: the charger, the charging socket, the battery or the board.
- Lights or fan, but a black screen. Something is running, you just can’t see it. The screen, the backlight or the graphics may be the problem rather than the laptop itself.
- Turns on, then cuts out. It starts, then switches itself off after a few seconds or minutes. Battery, overheating or a board fault are common culprits.
- Gets to the logo, then stops. The hardware is probably working, but the laptop can’t load Windows or macOS. That can be a software problem or a failing storage drive.
- Shows an error or a symbol. A message, a beep pattern or flashing lights. These are clues, so take a photo before you try anything.
Make a note of which one you’ve got. If you end up bringing it to a repair shop, telling them exactly what happens will save time and, often, money.
Checks to try at home before you pay anyone
None of these need tools, and none of them will make things worse.
Check the socket and the charger
It sounds obvious, but start with the wall. Dell’s own advice is to make sure the socket works by testing it with another device. Then look at the charger. Many chargers have a small light on the brick or the plug end. Dell says that if the light is off, you should reseat the power cable, and if it stays off, the adapter itself is likely to need replacing.
Apple gives similar advice for Macs: make sure the power cable is undamaged and plugged securely into both the laptop and a working socket, and try another compatible cable or adapter if you have one.
If you know someone with the same charger, borrowing it for five minutes is one of the quickest tests there is.
Unplug everything else
Take out USB sticks, external drives, hubs, docks, printers and anything else connected. Both Apple and Dell list this as a step. A faulty accessory can sometimes stop a laptop starting.
Hold the power button for longer
A normal press isn’t always enough to wake a laptop that has frozen in a strange state.
- On a Mac, Apple says to press and hold the power button for about 10 seconds, then press and release it as normal. On MacBooks with Touch ID, the Touch ID button is the power button.
- On some Dell laptops, Dell describes holding the power button for 30 to 35 seconds to discharge residual power, until the power light blinks three times. Dell says this only applies to certain models.
Other brands have their own versions of this, so check the manufacturer’s support site for your model.
Take out the battery, if it comes out
Most modern laptops have a sealed battery, so skip this if yours does. But if the battery is removable, Dell suggests taking it out and trying to start the laptop on the charger alone. If it starts, the battery is a strong suspect.
Give it time on the charger
If the battery has run completely flat, some laptops won’t respond straight away when you plug them in. Leave it on a charger you know works for a while before deciding it’s dead.
Try an external screen
If you can hear the fan or see lights but the screen stays black, plug the laptop into a TV or monitor. If a picture appears there, the laptop is working and the problem is with the built-in screen or its connection.
The usual reasons a laptop won’t turn on
If the home checks don’t bring it back, it’s normally one of these.
A failed charger or cable
Chargers live hard lives. They get wrapped tightly, trodden on, yanked out of the wall and bent at the same point every day. A charger that has given up is the cheapest fix on this list, which is why it’s worth ruling out first.
A worn charging socket
The socket on the laptop where the charger plugs in (sometimes called the DC jack or power jack) takes a lot of strain. If you have to wiggle the plug to get it to charge, or it charges at one angle only, the socket is probably loose or damaged. Power jack repairs are one of the jobs listed on our laptop repairs page.
A dead or failing battery
Batteries wear out with age and use. A tired battery might stop holding charge, cut out without warning, or stop the laptop starting at all. On laptops with sealed batteries, replacing it means opening the case.
Liquid damage
Tea, coffee and water are the classic three. Sometimes the laptop dies straight away. Sometimes it seems fine for days and then stops as corrosion builds up. If you’ve spilled something, switch it off, unplug it, and don’t keep trying to turn it on. Bring it in as soon as you can.
The screen, not the laptop
This is the good news scenario. If the laptop is running but the screen is black, the fault might be the display panel, the backlight or the cable between the screen and the base. The rest of the laptop, and your files, are usually untouched.
A storage drive or software problem
If the laptop powers up but never gets past the logo, the drive that holds Windows or macOS may be failing, or the operating system itself may be damaged. These can often be repaired, and sometimes the files can be rescued even when the drive is on its way out.
A fault on the main board
The motherboard (or logic board on a Mac) is the main circuit board that everything plugs into. Faults here can come from liquid, heat, a power surge or plain old age. Board repairs are more involved and not every board fault is worth fixing, but they’re not automatically the end. Motherboard repairs are on our list of laptop services.
Overheating
Dust builds up inside laptops over the years. If the fan can’t move air properly, the laptop may switch itself off to protect itself, sometimes only seconds after starting. A proper internal clean can make a real difference.
MacBook won’t turn on? A few extra points
Apple has its own support page for a Mac that doesn’t turn on, and a few points from it are worth knowing:
- If you see a flashing question mark or a circle with a line through it, Apple says your Mac is on but not starting up. That’s a startup problem, not a power one, and Apple has separate guidance for it.
- If the screen stays blank, Apple says the issue could be software related.
- Resetting the SMC may help on older Intel-based Macs. Apple says you don’t need to do this on a Mac with Apple silicon.
- If your Mac still doesn’t turn on after the basic checks, Apple says it may need a service.
We repair MacBooks as well as Windows laptops from Dell, HP, Lenovo, Acer, Asus, Samsung, Toshiba and other brands.
What about your files?
This is usually the first thing people ask, and it’s a fair worry.
The good news is that a laptop not turning on doesn’t mean your files are gone. In many cases the fault is with power, the screen or the board, and the storage drive is fine. Once the laptop is working again, your files are where you left them.
Where the drive itself is failing, or the laptop isn’t worth repairing, it’s often still possible to recover data. Data recovery, backup and restoration are services we offer. We can’t promise every file in every case, and we’ll be straight with you about what’s possible once we’ve looked.
Two tips while you wait:
- Stop trying to turn it on over and over. If the drive is struggling, repeated attempts don’t help.
- Don’t pay for a new laptop until you know whether the data can be saved. If it can, you may be able to transfer everything straight across.
And once you’re up and running again, set up a backup. It’s the cheapest insurance there is.
Repair or replace: how to decide
There’s no single rule, but these questions usually get you to the right answer.
How old is it, and was it any good to begin with?
A two or three year old laptop with a decent spec is often well worth repairing. A much older budget model that was already slow may not be, even if the repair itself is simple.
What is the fault?
A charger, a socket, a battery or an internal clean are usually reasonable repairs. A badly corroded board after a big spill is a different conversation. Get a diagnosis first. The repair quote often settles the question by itself.
How does the repair compare to replacing it?
Compare the repair quote with what you’d actually spend on a replacement you’d be happy with, not the cheapest laptop on a shop shelf. If the repair is a small fraction of that and the laptop still does what you need, repair. If it’s getting close, think hard.
Has it gone wrong before?
One fault in five years is bad luck. A third repair in eighteen months is a pattern.
Were you thinking of upgrading anyway?
If you were already eyeing a new laptop, a breakdown can be a good moment to make the change, as long as you don’t throw value away in the process.
That last point is where we’re different from a lot of repair shops. Because we buy tech as well as fix it, a laptop that isn’t worth repairing can still be worth money. We buy laptops, MacBooks and desktop PCs, and faulty devices still have value for parts and refurbishment. You can see how it works on our We Buy Your Phones page: we test the device in front of you, make one offer, and pay you there and then. No obligation, and the valuation is free.

FAQs
Why won’t my laptop turn on even when it’s plugged in?
The most common reasons are a faulty charger or cable, a worn charging socket on the laptop, or a battery that has failed. Test the socket and charger first, unplug any accessories, and hold the power button down for longer than usual. If it still won’t start, it needs a proper diagnosis.
Can a laptop that won’t turn on be fixed?
Often, yes. Chargers, charging sockets, batteries and screens are all repairable, and many software and board faults can be fixed too. A diagnosis will tell you what’s wrong and what it will cost before you commit.
Will I lose my files if my laptop won’t turn on?
Not necessarily. In many cases the storage drive is fine and your files are still there once the laptop is repaired. If the drive itself has a problem, data recovery is often possible, though no one can guarantee every file.
Is it worth repairing an old laptop?
It depends on the fault, the cost and what you need the laptop for. A cheap fix on a laptop that still does the job is usually worth it. An expensive repair on an old, slow machine often isn’t. Get a quote and compare it with the cost of a replacement you’d actually want.
Can I sell a laptop that won’t turn on?
Yes. We buy faulty laptops and MacBooks as well as working ones, because they still have value for parts and refurbishment. Bring it in for a free, no-obligation valuation, or see how it works on our We Buy Your Phones page.
