Why Isn’t My Laptop Turning On? 5 Common Causes & How to Fix Them

Is there anything more frustrating than going to use your laptop and it refuses to turn on?

It worked perfectly fine yesterday, so why isn’t it working today?

Read on to discover 5 of the most common reasons why your laptop won’t turn on. Plus, how to fix it quickly and at minimal expense.

1. A Power Problem

One of the most common causes of a laptop not turning on is an issue with the power. If your laptop is connected to a power source, then the first thing to do is check that it is properly plugged in.

If your laptop is not currently connected to a power source, the next step is to see if it needs charging. If you know you have charged your laptop but it still won’t turn on, check to see if there are any issues with its power plug, such as any signs of damage or burning.

2. A Monitor Issue

If power is not the problem, the next most probable cause of your laptop not turning on is an issue with the display screen or monitor.

Occasionally, your laptop may display may be stuck in sleep mode, which is why it appears not to be turning on. However, in most cases, something has happened to damage the monitor, such as spilled juice or dropping it on the floor.

3. An Internal Fault

Less common, but still a possibility, if it is not the power source or monitor that is the problem, there may be an issue with one of your laptop’s internal components.

If you suspect that there might be an internal fault with your laptop, don’t try to open it up to find this yourself, as you are likely to do more harm than good.

Instead, find a reputable laptop repair company to inspect your laptop for you, such as this laptop repair London shop. They will also be able to assist you with any repairs that need doing.

4. A Booting Issue

If your laptop is turning on but you are met with a blue screen and a series of booting options, then follow the instructions, and your laptop should reboot itself and start working properly again.

If you follow the instructions and your laptop will still not turn on properly, then again, you will need to visit a computer repair shop.

5. External Drives

If your laptop is plugged into any external drives, then this could be the reason why it is not turning on.

Although laptops are a fairly clever piece of technology, they aren’t immune to becoming confused and, if you have any external drives, such as flash drives, plugged in, they may not turn on.

Therefore, make sure to check and see if any external drives are plugged into your laptop and, if they are, unplug them and then try turning it on again.


It can be incredibly frustrating when your laptop won’t turn on, especially if you have urgent work to do. The good news is, in most cases, the problem is easily fixed without the need to book your laptop in for repairs.

If you do need the help of a laptop repair shop, it is worth weighing up the cost of repairs versus the value of the device. For example, if the laptop is very old, it may make more financial sense to invest in a newer model.
