If you only have a minute, use the table below to find your symptom. Then jump to the matching section for the safe checks and the signs that it needs a technician.
| Symptom | Quick check at home | Book a repair when |
|---|---|---|
| Will not turn on | Try another power point and a hard reset | There are no lights or sounds at all |
| Will not charge | Check the cable, plug and charging port | A known good charger still fails |
| Running slowly | Close startup apps and check free storage | It stays slow after a cleanup |

What to Know
Why won’t my laptop turn on?
A laptop that will not turn on usually has a power supply, battery or board fault. However, it can also be a display fault that only looks like a dead laptop, so a few checks help narrow it down.
First, listen and look closely. If you hear the fan, see a keyboard light or notice the charging light, the laptop may actually be running with a blank screen.
What can you check safely at home?
- Plug the charger into a different wall outlet and skip any power board.
- Check the charger light, if it has one, and look for damage along the cable.
- Unplug every accessory, including USB drives, docks and memory cards.
- Hold the power button down for about thirty seconds, then try again with the charger connected.
- If the screen stays dark but you hear activity, connect an external monitor.
These steps clear many simple power glitches. Still, they will not fix a failed component.
When should you book a repair?
Book a repair when there are no lights, no fan and no sound after the checks above. You should also stop if the laptop turns on for a moment and then cuts out, since that often points to a board or power fault.
Our guide on what to do when a laptop will not turn on covers the likely causes in more detail.
In Detail
Why won’t my laptop charge?
A laptop that will not charge usually has a faulty charger, a worn charging port or a battery near the end of its life. In some cases, the charging circuit on the board is at fault instead.
Often the charger is the culprit, because cables bend and fray with daily use. That is why testing the charger first saves time.
What can you check safely at home?
- Look along the whole cable for kinks, fraying or melted spots.
- Check the charging port for lint, dust or a loose feel.
- Try a different wall outlet without a power board.
- If you can borrow a matching charger of the right wattage, test with that.
- For USB C laptops, try another port on the laptop if it has one.
Never push metal objects into the port to clean it. Instead, use a soft brush or a gentle puff of air with the laptop off.
When should you book a repair?
Book a repair if a known good charger still does not charge the laptop. You should also book one if the plug feels loose, sparks or gets hot, or if the charger smells of burning.
Our page on a laptop that will not charge explains how technicians test the port, battery and board. When the socket itself is loose or worn, a laptop charging port repair is usually the fix.
Our Advice
Why is my laptop so slow?
A slow laptop usually has too many programs running, a nearly full drive or an ageing hard drive. Malware and pending updates can also drag performance down.
In many cases, this is one of the laptop problems you can improve without any parts. So it is worth trying the software steps first.
What can you check safely at home?
- Restart the laptop fully instead of only closing the lid.
- Open the task manager and see which apps use the most memory or disk.
- Turn off apps you do not need at startup.
- Check free storage and remove large files you no longer need.
- Install pending system updates, then restart again.
- Run a full scan with your security software.
When should you book a repair?
Book a repair if the laptop stays slow after these steps, or if the disk shows full activity all the time. Also book one if you hear clicking from the drive or see errors about the disk, since a failing drive can lose data.
An older laptop with a mechanical hard drive often feels much faster after a move to a solid state drive. Our slow laptop fix page explains the options. If a scan finds malware you cannot remove, our virus removal Melbourne service can clean it safely.
Key Points
Why does my laptop get so hot?
A laptop that runs very hot usually has blocked vents, a clogged fan or dried thermal paste. Heavy tasks such as gaming or video editing also raise the temperature, so some warmth is normal.
Heat matters because it slows the processor and shortens the life of parts. Over time, it can also stress the battery.
What can you check safely at home?
- Use the laptop on a hard, flat surface instead of a bed, couch or lap.
- Look at the vents and check they are clear of dust and fluff.
- Close heavy apps and browser tabs you do not need.
- Keep the laptop out of direct sun and hot cars.
Avoid opening the case to clean the fan unless you know the model well. Otherwise, it is easy to damage clips, cables or the fan blades.
When should you book a repair?
Book a repair if the laptop shuts down on its own, slows down badly when warm, or feels too hot to touch comfortably. A professional clean and fresh thermal paste often brings temperatures back down.
See our laptop overheating fix page for more on causes and cooling.
Good to Know
Why is my laptop fan so loud?
A loud fan usually means the laptop is working hard, the fan is full of dust or the fan bearing is wearing out. The first two are common and often easy to improve.
A steady whoosh under load is normal. On the other hand, grinding, rattling or clicking sounds are not.
What can you check safely at home?
- Open the task manager and look for apps using a lot of processor time.
- Restart the laptop to clear stuck background tasks.
- Check that the vents are not blocked by a soft surface.
- Listen for whether the noise changes when the laptop is idle.
When should you book a repair?
Book a repair if the fan grinds, rattles or runs at full speed all the time, even when idle. Also book one if the fan stops completely while the laptop gets hot, because that can lead to shutdowns.
Our laptop fan noise fix page explains cleaning and fan replacement.
Next Steps
What should I do about a cracked or black screen?
A cracked screen usually needs a new display panel, while a black screen can come from the panel, the display cable or the graphics hardware. An external monitor test helps tell these apart.
Cracks tend to spread over time, especially when the lid opens and closes. So it is best to act early.
What can you check safely at home?
- Connect an external monitor or TV with a suitable cable.
- Shine a torch at the dark screen and look for a faint image.
- Try the brightness keys in case the backlight is simply turned down.
- Restart the laptop and watch for the logo on startup.
If the external monitor shows a picture, the laptop itself is working and the fault sits in the display area. However, if nothing appears anywhere, the problem may be deeper.
When should you book a repair?
Book a repair for any cracked glass, lines, flickering or dark patches. Also stop using the laptop if broken glass is loose, since sharp pieces can cut fingers.
Our cracked laptop screen repair page covers the replacement process.
Expert Tips
Why are some keys not working?
Keys that stop working usually have dirt or crumbs under them, a software setting that changed or a damaged keyboard. Liquid spills are a common cause as well.
A quick test shows whether the fault is in the software or the hardware. That way, you know which path to take.
What can you check safely at home?
- Restart the laptop and test the keys again.
- Open the onscreen keyboard and see if those keys work from there.
- Plug in a USB keyboard and check if it types normally.
- Turn the laptop off, tilt it gently and tap out loose crumbs.
- Check keyboard settings such as filter keys or a different language layout.
When should you book a repair?
Book a repair if the same keys stay dead after a restart, or if keys type on their own. Also book one if any keys feel sticky after a spill, because liquid may have reached the board.
Our laptop keyboard repair page explains key and keyboard replacement.
The Basics
Why is my laptop hinge loose or broken?
A loose or broken hinge usually comes from wear, a cracked mounting point or a screw that has worked free inside the case. Opening the lid from one corner also adds stress over time.
Hinge faults get worse with use. If you keep opening a damaged lid, the case can crack and the display cable can tear.
What can you check safely at home?
- Open the lid slowly from the centre, never from one corner.
- Watch the edge of the case near the hinge for gaps or movement.
- Check whether the screen flickers when you move the lid.
- Keep the lid at one angle as much as possible until it is fixed.
When should you book a repair?
Book a repair as soon as the case flexes, creaks, cracks or separates near the hinge. Also book one if the screen flickers as you move it, since the cable may be under strain.
Our laptop hinge repair page explains what the repair involves.
What to Know
What should I do if I spilled liquid on my laptop?
If you spill liquid on your laptop, turn it off and unplug it straight away. Speed matters more than anything else, because liquid and power together cause the most damage.
Safety comes first. If you see smoke, smell burning or notice sparks, keep your distance and do not touch the laptop until it has stopped.
What should you do right now?
- Hold the power button to shut the laptop down if it is still on.
- Unplug the charger from the wall and then from the laptop.
- Remove any USB drives and accessories.
- Turn the laptop upside down in a tent shape so liquid can drain out.
- Wipe away any visible liquid on the outside with a soft cloth.
What should you avoid?
- Do not turn it on to check whether it still works.
- Avoid a hair dryer, heater or oven, since heat can push liquid further in and damage parts.
- Leave the charger unplugged.
- Skip the bowl of rice, because it does not reach liquid inside the case.
Even when the laptop seems fine, liquid can sit under the keyboard and corrode the board slowly. That is why a spill always needs a professional clean and inspection.
When should you book a repair?
Book a repair as soon as possible after any spill, especially with sugary drinks, coffee or juice. Our page on liquid spilled on a laptop explains what happens next.
In Detail
Why is my battery draining so fast?
A battery that drains fast is usually worn out from age and charge cycles. Also, bright screens, background apps and high power settings can drain it quickly even when it is healthy.
All laptop batteries lose capacity over time. So a battery that once lasted a full day will eventually last only a short while.
What can you check safely at home?
- Lower the screen brightness and close apps you are not using.
- Switch to a balanced or battery saver power mode.
- Check the battery health report in your system settings.
- Look at which apps use the most battery in the power settings.
Why is a swollen battery dangerous?
A swollen battery can push up the keyboard, lift the trackpad or open a gap in the case. If you notice any of these signs, stop using the laptop and unplug it right away.
- Never press on the bulge or try to flatten it.
- Leave removal to a technician, and never puncture or bend the battery.
- Stop charging it.
- Keep the laptop on a hard surface, away from anything flammable.
When should you book a repair?
Book a repair when battery health is low, the laptop shuts down with charge still showing, or the case bulges in any way. Our laptop battery replacement page explains the process.
Our Advice
What warning signs mean you should stop using the laptop?
Some warning signs mean you should stop using the laptop straight away instead of trying more checks. These signs point to a safety risk or a real chance of losing data.
In short, if you notice any of the signs below, power off, unplug the charger and leave the laptop alone.
| Warning sign | What it can mean | What to do |
|---|---|---|
| Burning smell | An overheating part or charger | Power off and unplug straight away |
| Swelling or bulging case | A swollen battery | Stop charging and do not press on it |
| Smoke | A serious electrical fault | Keep clear and unplug only if safe |
| Sparks at the port or charger | A short circuit or damaged plug | Unplug at the wall and stop using it |
| Liquid inside the case | Risk of short circuit and corrosion | Power off and do not turn it on |
| Clicking drive with important data | A hard drive close to failure | Shut down and avoid further use |
A clicking drive deserves special care. Each restart can make the damage worse, so it is safer to stop and ask about laptop data recovery before trying anything else.
Other general signs also tell you a laptop needs attention soon. For example, watch for these.
- Frequent crashes, freezes or blue screens.
- Unusual noises from inside the case.
- Error messages about the drive, memory or battery.
- Parts of the case that feel loose, cracked or hot.
- Files that disappear or refuse to open.
None of these signs always means a costly fault. Even so, catching them early often keeps a small repair from turning into a bigger one.
