First confirm the PC is awake by checking Caps Lock or opening Task Manager; if the system responds but the screen remains black, the issue lies with the display, GPU driver, or monitor power state. 2. Update or roll back graphics drivers through Device Manager or download the latest version from Intel, NVIDIA, or AMD websites to resolve compatibility issues. 3. Adjust power settings by disabling fast startup, resetting sleep settings, and preventing the GPU from being turned off for power savings. 4. Check monitor and cable connections, reseat or replace cables, and test different ports or integrated graphics to rule out hardware faults. 5. Disable hybrid sleep and set PCI Express link state power management to Off in advanced power settings to prevent wake failures. 6. Run the built-in Power Troubleshooter via Settings to detect and fix power-related problems. 7. Update BIOS and chipset drivers from the manufacturer’s website, following instructions carefully to avoid system damage. The most common causes are outdated drivers, power settings, GPU power management, or faulty cables, and most cases can be resolved without reinstalling Windows.

If your Windows 10 screen stays black after waking from sleep, you're not alone — it's a common issue that can stem from power settings, drivers, or hardware behavior. Here’s how to fix it step by step.

1. Check if the PC is actually waking up

Before assuming it’s a display issue, confirm your PC is waking from sleep:

• Press Caps Lock or Num Lock — if the indicator light toggles, the system is responding.
• Try Ctrl Shift Esc to open Task Manager (if it appears, the system is awake but the display isn’t showing).

If the system is awake but the screen is black, the problem is likely with the display, GPU driver, or monitor power state.

2. Update or roll back graphics drivers

Outdated, corrupt, or incompatible GPU drivers are a top cause.

Steps:

• Boot into Windows (you may need to restart and use Safe Mode if the screen stays black).
• Press Win X → Device Manager.
• Expand Display adapters, right-click your GPU (e.g., Intel HD Graphics, NVIDIA, AMD), and:
  • Choose Update driver → "Search automatically for updated driver software".
  • If the issue started recently, try Roll Back Driver (if available).
• Alternatively, download the latest driver from the manufacturer’s website:
  • Intel Driver Support
  • NVIDIA Drivers
  • AMD Drivers

After updating, restart and test sleep/wake.

3. Adjust power and sleep settings

Sometimes Windows or the graphics card turns off the display incorrectly.

Try these fixes:

• Disable fast startup:

  • Go to Control Panel > Power Options > Choose what the power buttons do.
  • Click Change settings that are currently unavailable.
  • Uncheck Turn on fast startup (recommended) → Save changes.

• Reset sleep settings:

  • In Power Options, select Change plan settings → Restore default settings for this plan.

• Prevent the GPU from turning off:

  • In Device Manager, right-click your GPU → Properties → Power Management.
  • Uncheck "Allow the computer to turn off this device to save power".

4. Check monitor and cable connections

• Ensure your monitor is receiving power (check LED indicator).
• Reseat the video cable (HDMI, DisplayPort, etc.) at both ends.
• Try a different cable or port (e.g., switch from HDMI to DisplayPort).
• If using a desktop, try connecting the monitor to a different GPU output or integrated graphics.

Sometimes the GPU fails to reinitialize the display signal after sleep — a cable or port issue can make this worse.

5. Disable hybrid sleep and adjust advanced power settings

Hybrid sleep can cause wake issues on some systems.

Steps:

• Open Power Options → Change plan settings → Change advanced power settings.
• Expand Sleep → Allow hybrid sleep → Set to Off.
• Also set PCI Express > Link State Power Management to Off.

Click Apply → OK.

6. Run the Power Troubleshooter

Windows includes a built-in tool to detect power-related issues.

• Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
• Run the Power troubleshooter and apply any recommended fixes.

7. Update BIOS and chipset drivers

An outdated BIOS can cause sleep/wake problems.

• Check your PC or motherboard manufacturer’s website for BIOS updates.
• Follow their instructions carefully — incorrect BIOS flashing can brick your system.
• Also update chipset drivers from the same source.

Summary

Most black screen after sleep issues in Windows 10 come down to:

• Graphics drivers needing update or rollback
• Power settings (especially hybrid sleep or fast startup)
• GPU power-saving features interfering
• Loose or faulty display cables

Start with driver updates and disabling fast startup — those fix the majority of cases. If the problem persists, test with an external monitor or try a clean boot to rule out software conflicts.

Basically, it's usually fixable without a full reinstall.
