This post shows you the details: How to Boot into Windows Recovery Mode on Bootable/Unbootable PCs.

Solution 2. Turn off Fast Startup/Hibernation

When you shut down your computer, Fast Startup puts your computer into a hibernation state instead of shutting down completely. This speeds up Windows startup. However, sometimes this feature results in a black screen.

So, you can try to disable the Fast Startup option and check if the black screen disappears.

Step 1. In the Windows search box, type Choose a power plan and then click it.

Step 2. In the left panel, click Choose what the power button does.

Step 3. Click Change settings that are currently unavailable.

Step 4. Uncheck the checkboxes next to Turn on fast startup (recommended) and Hibernate. After that, click Save changes.

Under normal circumstances, the graphics driver will be updated automatically along with Windows updates. Nonetheless, in many cases, the black screen issue is caused by outdated graphics card drivers. Therefore, if you stuck with the “Windows black screen after sleep” situation, you can try to update the driver manually.

Step 1. On your taskbar, right-click the Start button to select Device Manager.

Step 2. Expand the Display adapters option, then right-click the display device and select Update driver.

Step 3. Follow the instructions on your computer to complete the whole process.

Step 1. Press the Windows + I keyboard shortcut to open Settings.

Step 2. Click Update & Security > Troubleshoot > Additional troubleshooters.

The computer’s inability to wake up from sleep mode may also be caused by an outdated BIOS. To rule out this cause, you can attempt to update the BIOS.

Upgrading BIOS has certain risks. If the model of the upgraded BIOS installation file is different from the motherboard model, the firmware is not supported, etc., the computer may completely freeze. So, it is highly recommended that you think carefully.

If you have considered updating the BIOS, please make sure there is sufficient power supply during the process. And, you can refer to this article for the operation: How to Update BIOS Windows 10 | How to Check BIOS Version.

Recover Data From the Computer That Keeps Black Screen

If you have tried all the methods above and still cannot get rid of the “Window black screen after sleep” issue, then you may need to consider reinstalling Windows or seeking help from a professional computer repair organization or company.

But before that, you’d better restore the data on your computer to avoid file loss or damage. How to recover files from a computer that shows a black screen? This is when professional data recovery software, MiniTool Power Data Recovery, can play a huge role.

This data restore software can effectively recover data in a variety of scenarios where data is inaccessible or lost, such as recovering data after a Windows downgrade, recovering data after reinstalling Windows, recovering files from a drive with damaged file system, and so on.

Its Bootable Media Builder feature helps build a bootable data recovery tool and then boot your computer to scan and recover data. Note that this feature is only available for registered versions.

Now follow the instructions below to create a bootable media and perform data recovery from the unbootable computer.

Before you do, you need to prepare a USB drive that does not contain any important files. This is because during the bootable media builder process, the USB drive will be formatted and the data on it will be deleted. And, you need to prepare a functioning computer as well.

Step 1. Create a bootable USB drive.

First, download and install MiniTool Power Data Recovery on a working computer. You can click the button below to download the free edition of this hard drive data recovery service, then you will have the ability to upgrade it to a full edition.

Next, launch the registered MiniTool Power Data Recovery. Click the Bootable Media Builder icon to create a bootable USB drive.

Step 2. Boot the black-screen computer from the bootable disk.

After creating a bootable media, you need to insert the media into the computer with a black screen and then boot your device from the drive by referring to this tutorial: How to Boot from Burned MiniTool Bootable CD/DVD/USB Flash Drive.

Step 3. Scan the target partition/device.

On the main interface of MiniTool Power Data Recovery, you need to select the target drive that you want to recover data from and click the Scan button to start scanning. Since system crashes usually only affect system disk data, here we choose to scan the C drive.

If you want to scan the whole computer, you can move on to the Devices section and choose the entire device to scan.

scan the C drive

Now you need to wait until the whole scanning process is completed.

Step 4. Find and preview the found files.

After scanning, you will find that all found files on the selected partition/device are listed on the scan result page. By default, they are listed in a tree structure under the Path category list, and you can expand each of the folders to find the necessary files. But this is time-consuming. To locate the desired files in a fast way, you can move on to the Type category to view files by file type, such as pictures, documents, videos & audio, etc.

view files by file type

The Filter feature can also perform the same function – view found files by file type. Besides, with the Filter button, you can filter out unwanted files by file category, file size, and file modification date.

filter the found files

It is crucial for you to preview the found files to ensure that they are needed. There are two ways available for previewing the found files: double-clicking on each of the found files & selecting a file and clicking the Preview button.

Step 5. Save recovered files.

Finally, you should tick all the desired files and then click the Save button to specify a file storage location for the recovered files. Since you cannot access the hard drives on the computer with a black screen, you need to save the files to an external drive.

save the files

That’s all the steps on how to recover data from a computer that won’t boot properly. After rescuing your files, you can try to reinstall Windows or take the computer to a repair center for repair.
