How do you fix a laptop that won't wake up from sleep?

Troubleshooting a Laptop that Won’t Wake from Sleep

When your laptop fails to wake up from sleep mode, it can be frustrating and disruptive. Here’s a step-by-step guide to resolve this issue:

1. Perform a Simple Power Cycle

• Shut down the laptop completely.
• Unplug the power adapter and remove the battery (if possible).
• Press and hold the power button for 30 seconds.
• Reinsert the battery and plug in the power adapter.
• Power on the laptop and check if it wakes from sleep.

2. Check for Windows Updates

• Navigate to “Start” > “Settings” > “Update & Security” > “Windows Update.”
• Check for any pending updates and install them.
• Restart the laptop after installing updates and check if the sleep issue is resolved.

3. Run the Power Troubleshooter

• Go to “Start” > “Settings” > “System” > “Troubleshoot.”
• Select “Power” and click on “Run the troubleshooter.”
• Follow the on-screen instructions to complete the troubleshooting.

4. Adjust Sleep Settings

• Open “Control Panel” and navigate to “System and Security” > “Power Options.”
• Select “Change plan settings” for your current power plan.
• Click on “Change advanced power settings.”
• Under “Sleep,” expand the “Allow Hybrid Sleep” option (if available) and disable it.
• Save the changes and restart the laptop.

5. Update or Reinstall Device Drivers

• Go to “Device Manager” by searching for it in the Windows search bar.
• Expand the “Display adapters” category.
• Right-click on your graphics card and select “Update driver software.”
• If an update is available, install it and restart the laptop.
• If no update is available, try uninstalling the driver and restarting the laptop. Windows will automatically reinstall the default driver.

6. Check for Hardware Faults

• If none of the above steps resolve the issue, you may need to check for hardware faults.
• Try connecting an external monitor to see if the laptop output works.
• If the external monitor displays an image, the issue may lie with the laptop’s LCD screen or its connection.
• If the external monitor also remains black, the problem may be with the motherboard or other hardware components.

7. Seek Professional Help

• If you are unable to resolve the issue on your own, it’s recommended to seek professional help from a computer repair technician.
• They can diagnose and fix any hardware or software problems that may be causing the laptop’s sleep mode issue.
