Screen damage Watch out for

Before You Start

A soft, dry microfibre cloth for cleaning the screen
An external monitor (or a TV with HDMI input) to test whether the problem is with the screen or the graphics hardware
A compatible HDMI, DisplayPort, or USB-C cable to connect the external display
Your HP laptop model number, printed on the service label on the bottom of the laptop
Windows administrator access to update drivers and run system checks
Your HP warranty information, available at the HP Support website if you have your serial number
Steady work surface and good lighting so you can see small details and screws clearly

Check first: If your screen is cracked, has bleeding black spots, or shows physical impact damage, stop immediately. Opening the laptop or trying DIY repairs can void your warranty and make things worse. Contact HP Support for warranty assessment.

Step-by-Step Instructions

Identify the Exact Symptom

Before you touch any settings, look closely at what your monitor is actually doing. Does the screen stay completely black when you press the power button? Does it flicker while you work? Is the picture washed out, too dark, or showing strange colours? Take note of whether the problem happens only on battery power or only when plugged into the mains.

Write down when the problem started, too. Did it happen after a Windows update, after you dropped the laptop, or for no obvious reason? This information helps you choose the right fix and saves you from trying random solutions. A quick observation now can save you 30 minutes of guessing later.

Tip: Take a photo of the screen with your phone. If the issue is visible in the photo, it is likely a hardware or panel problem. If the photo looks normal, it is more likely a software or settings issue.

Perform a Hard Reset

A hard reset drains all residual power from your HP laptop and clears minor hardware glitches. This is the single most effective fix for a screen that will not turn on or wakes up blank. Disconnect the power cable and remove the battery if your model has a removable one. Many newer HP laptops have sealed batteries, so skip that step if you cannot easily access it.

Press and hold the power button for 15 seconds. Release it, then reconnect the power cable and press the power button once to turn the laptop on. This is not the same as restarting Windows; it forces the motherboard to discharge fully. Try turning on the laptop or closing and reopening the lid to wake the display.

Tip: If the laptop has a removable battery, take it out and hold the power button for 15 seconds with both the battery and the power cable disconnected. This clears the deepest level of residual charge.

Connect an External Monitor

Plug your HP laptop into an external monitor or TV using an HDMI, DisplayPort, or USB-C cable. Press the Windows key plus P on your keyboard and choose one of the duplicate or extend options. If the external screen shows a clear picture, your laptop's graphics card and operating system are working fine. The issue is likely the built-in screen panel, the display cable, or the lid switch.

If the external screen is also blank or shows the same flickering and colour problems, the issue is deeper, in the graphics driver, Windows settings, or the GPU itself. This test is the fastest way to split your troubleshooting in half. Always reconnect the cable securely at both ends before you assume the worst.

Warning: If the laptop works perfectly on an external monitor, do not use the laptop with the lid closed for long periods without proper ventilation. This can cause overheating and permanent internal damage.

Update or Roll Back Display Drivers

Outdated, corrupted, or incompatible graphics drivers cause many HP monitor issues, including flickering, poor resolution, and random blackouts. Right-click the Start button and select Device Manager. Expand the Display adapters section and note the name of your graphics chip, which is usually Intel, AMD, NVIDIA, or a combination.

Right-click the adapter name and choose Update driver, then select Search automatically for drivers. If Windows does not find a new version, visit the HP Support website and enter your laptop model number to download the latest driver directly. If the problem started right after a recent update, choose Properties, then the Driver tab, and select Roll Back Driver to return to the previous working version.

Tip: After updating or rolling back a driver, always restart your laptop before testing the screen. Old driver files can remain active until the next reboot.

Adjust Brightness and Refresh Rate Settings

A screen that is too dark to see or appears to flicker may have incorrect display settings. Press the F2 key or the function key with a sun icon on your HP keyboard to raise the brightness. Some HP models require you to hold the Fn key at the same time. If the brightness is stuck at maximum or minimum, the display driver has not loaded correctly, so return to Step 4.

Right-click on the desktop and select Display settings, then scroll to Advanced display settings. Check that the refresh rate matches the native specification of your HP screen. Many HP panels run at 60Hz, but gaming models may support 120Hz or 144Hz. A mismatch can cause visible flicker and eyestrain. Change it via the adapter properties and confirm the correct rate.

Tip: If the refresh rate dropdown looks greyed out, click on the monitor hardware properties link and check whether Windows detects your panel correctly. An unknown or generic monitor profile can lock you out of proper settings.

Run Windows Display Diagnostics

Windows has built-in tools that can identify the source of your monitor trouble. Press the Windows key and type calibrate display colour, then open the matching Control Panel app. This tool walks you through gamma, brightness, contrast, and colour balance adjustments. It does not fix hardware damage, but it can solve washed-out images caused by incorrect colour profiles.

For flickering or rendering issues, search for Reliability Monitor in the Start menu. This shows you a timeline of system events and crashes. Look for critical events that match the times your screen went blank or flickered. If you see consistent hardware error codes, note them down for HP Support or a technician.

Tip: Use the Windows key plus Ctrl plus Shift plus B shortcut to reset the graphics driver instantly. Your screen will go black for a moment, and you will hear a beep. This is a harmless way to restart graphics without rebooting.

Check the Lid Switch and Physical Connections

Many HP laptops have a magnetic sensor that tells the computer when the lid is closed. If this sensor sticks or gets blocked by debris, the screen may stay black even when the laptop is on. Look for a small magnet or sensor marker near the front edge of the laptop base or around the keyboard. Dust or a loose screw can stop it from working.

The display cable runs from the motherboard through the hinge to the screen panel. If the screen flickers when you open or close the lid at certain angles, the cable is likely loose or damaged. This fix requires opening the laptop chassis and is not recommended for beginners. If you are comfortable with basic hardware work, power off, remove the battery, and carefully reseat the cable at both ends.

Warning: Opening your HP laptop may void your warranty and exposes you to electrical components. If you are not certain about cable connections or hinge disassembly, stop and contact HP Support or a certified repair centre.

Test with HP Hardware Diagnostics

HP includes a built-in diagnostic tool that tests your screen and other components. Turn the laptop off completely. Press the power button, then immediately press the Esc key repeatedly until the Startup Menu appears. Select System Diagnostics or the F2 key for the hardware test suite. Choose the Display test option if it is available.

The test cycles through solid colours, gradients, and patterns. Watch for dead pixels, stuck pixels, flickering, or any abnormal banding. When the test finishes, you will see a pass or fail result. If the test fails, you have confirmed hardware failure and should save the diagnostic code and contact HP Support. If it passes, your panel hardware is healthy and the issue is software-related.

Tip: Write down the 24-character failure ID that appears. HP Support will ask for this code to speed up your warranty claim.

Calibrate Colours and Enable Night Light

If your HP screen looks too warm, too cold, or just not right, you can fix it without specialist tools. Type calibrate display colour in the Windows search box and open the tool. Follow the prompts to adjust gamma, brightness, contrast, and colour balance. The tool shows you reference images so you can compare your screen to what Windows expects to see.

For blue light that causes eyestrain, open Settings, then System, then Display, and turn on Night Light. You can schedule it to turn on automatically at sunset or set custom hours. This is not a fault with the monitor, but a feature that makes long reading sessions more comfortable. You can also adjust the colour temperature slider if your panel supports it.

Tip: If you work with photos or design, run the built-in calibrator again after any major Windows update. Updates can silently reset your colour profile.

Clean the Screen and Inspect for Damage

Sometimes what looks like a monitor fault is just a dirty or dusty panel. Turn the laptop off and disconnect the power cable. Dampen a clean microfibre cloth with plain water or a screen-safe cleaner. Do not spray liquid directly onto the screen. Wipe the panel gently in one direction, applying light, even pressure.

While you clean, check for physical damage such as hairline cracks, pressure marks, or areas that look darker or lighter than the rest of the screen. Pressing too hard on the lid when packing your bag or placing heavy objects on the keyboard can damage the LCD panel without cracking the outer shell. On-screen damage like this cannot be fixed with software and requires panel replacement.

Warning: Never use paper towels, rough cloths, or household glass cleaners on an HP laptop screen. These can strip the anti-reflective coating and leave permanent scratches.

Restore, Reset, or Contact Support

If you have completed every hardware test and software fix and your screen still misbehaves, the final steps are recovery options. Use System Restore in Windows to return your laptop to a point before the problem started. Search for Create a restore point in the Start menu and follow the prompts. This will not touch your personal files, but it may remove recent apps and driver changes.

If System Restore does not help, back up your data and use the Reset this PC option in Settings. Choose the option that keeps your files but removes apps and reinstalls Windows. This is the last software step before hardware repair. When your screen is physically damaged or the HP hardware diagnostic fails, contact HP Support with your model number, serial number, and diagnostic failure ID. Authorised technicians can replace the panel, cable, or GPU correctly and safely.

Tip: Check your warranty status before paying for any repair. Many HP laptops carry a one-year parts and labour warranty, and some credit card companies extend that period automatically.
