Key takeaways
- Switch off, do not press the screen, and cover sharp cracks with clear tape before moving it.
- Connect an external monitor or TV. If it displays there, the rest of the laptop works and your files are safe.
- Copy your files out while you still can, then arrange a panel replacement for your exact model.
- Do not close the lid hard or keep using it. Cracks spread and shards can damage the keyboard.
Quick answer: what to do right now
- Switch the laptop off and unplug it. A cracked screen can show strange colours and sometimes shorts, so power is best kept off until you decide what to do.
- Stop pressing on the screen. Pressure spreads cracks and spreads black patches.
- Check for loose glass. If there are shards, keep the laptop open or lay it flat. Closing the lid can drive them into the keyboard.
- Cover sharp cracks with clear sticky tape or packing tape, laid flat over the damaged area, so fragments stay put and nobody gets cut.
- Do not clean the crack with liquid. Moisture can seep into the panel and the keyboard.
- Do not keep using it for ordinary work on the damaged screen, except briefly to save your files (see below).
Is it only the glass, or is the display damaged?
Look at the screen with the laptop off, then on if it is safe to do so. Different symptoms mean different things:
- A visible crack, but the picture is still clear around it: the panel is damaged, but the rest of the display may work.
- Black or dark patches that grow: the liquid crystal layer is damaged. These spread over time.
- Coloured or white vertical or horizontal lines: the panel or its connection is damaged.
- The screen is black but the laptop seems to be on (lights, sound, fan): the panel may be broken, or the cable may be loose. An external monitor test settles this.
- A cracked outer bezel or lid with a working screen: the plastic is damaged but the panel may be fine, and the repair is different.
Sometimes a screen shows damage without any visible crack. That happens when something pressed on the lid, such as a heavy item in a bag, or a pen or earphones left on the keyboard when the lid closed. The repair is still a panel replacement.
Test whether the rest of the laptop works
This test is worth doing before you decide anything. It tells you whether only the panel is broken.
- Connect the laptop to an external monitor or TV using an HDMI cable (some laptops use USB-C or DisplayPort).
- Switch the monitor to the matching input (HDMI 1, HDMI 2 and so on).
- Switch on the laptop. If the monitor shows nothing, press Windows key + P and choose Duplicate or Second screen only. You may need to press the arrow keys and Enter blindly.
If Windows appears on the external screen, the board, memory and drive all work and the damage is limited to the screen. That is the good news, and it applies in most cases.
If nothing shows even on the monitor, the cause may be more than the panel, for example a damaged graphics circuit or board. The technician can diagnose it.
Save your files before the repair
A screen replacement does not touch your drive, so your files stay where they are. Still, it costs nothing to have a copy, because anything can go wrong with a laptop that has had a knock.
- With an external monitor: plug in an external drive or flash drive and copy your Documents, Desktop, Pictures and Downloads folders. Also check for files in places such as the Videos folder, and your browser bookmarks.
- Online copies: sign in to OneDrive, Google Drive or Dropbox from the external screen and let it sync, or upload your most important folders.
- Without any display: do not worry. The technician can read the drive and copy files for you. Mention it before the work starts.
Check that the copies open before you hand the laptop over.
What a screen replacement involves
- Identify the exact panel. Screens differ in size, resolution, connector type, refresh rate and whether they are touch, so the replacement must match your model. The technician checks your laptop's model number and, where needed, the part number printed on the back of the panel.
- Remove the bezel, the plastic frame around the screen, which is usually held with clips and sometimes screws hidden under rubber pads or stickers.
- Disconnect the display cable and remove the old panel.
- Fit and test the new panel before the frame goes back on: brightness, colours, dead pixels, touch (if fitted) and the camera.
- Refit the bezel and check the hinges, because a crack often comes from a twisted lid or damaged hinge, and a tight or loose hinge can break the new panel.
It is normally one of the quicker repairs, but depends on parts being available for your model. Ask how long the part takes before agreeing.
Is it worth repairing? Screen, external monitor or replace the laptop?
In most cases a screen replacement is worthwhile, particularly if the laptop is otherwise healthy. Think about these points:
- Value of the laptop. If the laptop is fairly new, or powerful, repairing is clearly better than replacing it. If it is very old, slow or has other faults, compare the quote with the cost of a tested used laptop.
- How you use it. If it lives on a desk, an external monitor is a legitimate permanent solution, and the cracked lid can stay closed. If you carry the laptop around, you need a working screen.
- Other damage. Check the hinges, the bezel and the keyboard. A fall that cracked the screen can bend or break other things.
- Type of panel. Some models, especially touch laptops and some thin models, have the screen built into a more expensive display assembly. Ask your technician for an honest recommendation.
A good technician will give you the quote before work begins, tell you whether the parts are new or refurbished, and not push you to repair something that is not worth it.
Can I replace the screen myself?
It is possible on many laptops, and videos exist for popular models, but it is one of the easier repairs to get wrong. The risks are buying the wrong panel (by far the most common problem), breaking the plastic frame clips, tearing the thin display cable, and leaving shards or dust behind the new panel. If your laptop still has a removable battery or you are comfortable with small screws and ribbon cables, you can try, but get the exact part number first and disconnect the battery or power before you start. For most people, the cost of a technician is worth the guarantee on the part and the work.
Will insurance or warranty cover it?
Standard warranties normally cover manufacturing faults only, not cracked screens caused by drops or pressure. Accidental-damage cover, whether bought with the laptop or included in an insurance or business policy, may pay for it. If you have any such policy, read the terms before authorising a repair, because some insurers insist on using their own repairer or need a written assessment first. Keep the receipt and ask your repair centre for an itemised quote or report if you need to make a claim.
How to avoid cracking the next screen
- Never lift or carry a laptop by the screen or by a corner of the lid.
- Check the keyboard before you close the lid. Pens, earphones, memory cards and charger plugs left on the keys press marks into the screen.
- Use a padded sleeve and avoid stacking books or heavy items on top of a bag with a laptop in it.
- Do not close the lid on a camera cover that is thicker than the thin sliding type made for laptops.
- Open the lid from the centre of the edge, not a corner, so you do not twist it.
Screen protectors rarely stop a crack from pressure or a fall, so careful handling does more than any accessory.
Frequently asked questions
Can I keep using a laptop with a cracked screen?
It is not recommended for ordinary use. Cracks and black patches tend to spread, loose glass can drop into the keyboard or cut you, and a damaged panel can sometimes affect the display connection. Use it briefly to copy your files, and use an external monitor if you must keep working.
Is a cracked laptop screen worth repairing?
In most cases yes, if the rest of the laptop works and is not very old. A panel replacement costs far less than a new laptop for most models. If the laptop is old, slow or has other faults, ask the technician for an honest comparison before you decide.
Will a screen replacement delete my files?
No. The screen is separate from the storage drive, so replacing the panel does not touch your files. It is still wise to copy important files to an external drive or the cloud first, simply because any laptop can have another problem while it is being handled.
Can a cracked laptop screen be repaired rather than replaced?
The panel cannot be repaired. Once the display layer is cracked, the only fix is to replace the panel. If only the outer plastic frame or the lid is broken and the panel is fine, that part can be replaced on its own.
How do I know which screen my laptop needs?
The screen depends on the exact model: size, resolution, connector, refresh rate and touch or non-touch. Your technician finds it from the model name on the laptop and, if necessary, the part number on the back of the panel. Buying a panel without checking is the most common mistake.
Why is my laptop screen black but not cracked?
Pressure or an impact can break the display inside without any visible crack, and a loose display cable, backlight fault or graphics fault can also cause a black screen. Connect an external monitor. If the picture appears there, the problem is the panel or its cable.
