Tip: Remember to take out the hard drive and recover data from it. Connect the hard drive to another computer and then using the data recovery software that doesn't need any technical know-how and minimizes data risks.


Step 1. Create a bootable disk

Prepare an empty USB. If you have important data on it, copy the data to another device. When you create a bootable disk, the data on the USB will be erased. EaseUS Data Recovery Wizard WinPE Edition will help you create a bootable disk.

Connect the USB drive to PC, launch EaseUS Data Recovery Wizard WinPE Edition. Select the USB drive and click "Create" to create a bootable disk.




Step 2. Boot from the bootable USB

Connect the bootable disk to PC that won't boot and change your computer boot sequence in BIOS. For most users, it works well when they restart their computer and press F2 at the same time to enter BIOS.

Set to boot the PC from "Removable Devices" (bootable USB disk) or "CD-ROM Drive" (bootable CD/DVD) beyond Hard Drive. Press "F10" to save and exit.


Step 3. Recover data from a hard drive that won't boot

When you boot from the USB, you can run EaseUS Data Recovery Wizard from the WinPE bootable disk. Select the drive you want to scan to find all your lost files.

Fix 3. Hard Reset the Laptop to Resolve Laptop Blank Screen

Your laptop manufacturers should allow you to hard reset or factory reset your machine when it has trouble starting up or malfunctioning in other ways. If you have no idea how to do the hard reset, try to contact the manufacturer or seek help on the official support forum. This manner removes data and apps, still, it deserves an initial trial since it resolves the display blank or black issue mostly. Here, we take HP laptop as an example:

Step 1. Turn off the laptop. Remove the laptop from any port replicator or docking station.

Step 2. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers. Unplug the AC adapter from the laptop.





Step 3. Remove the battery from the battery compartment.

With the battery and power cord unplugged, press and hold the "Power button" for about 15 seconds to drain any residual electrical charge from the capacitors.

Step 4. Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.

Step 5. Press the "Power button" to turn on the laptop. The laptop starts normally or a startup menu opens.

Step 6. If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press "Enter".

After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.


Fix 4. Connecting an External Monitor to Test the Display

The screen might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor, and restart the computer. This test is helpful if the display is black but you can hear that the computer is operating. You can connect most monitors and other display devices like projectors using the VGA, DVI, HDMI, or DisplayPort cables. 

Step 1. Connect an external monitor to the laptop.

  • Know the video connectors on your computer and display devices to avoid problems and get the best possible picture quality.
  • An HDMI connection can also carry audio. HDMI audio is lost when using a DVI to HDMI adapter or cable solution. You cannot connect DVI-D to VGA.
Step 2. If the computer screen does not display on the external monitor, press "F4" until the screen image displays.

Step 3. If an image displays on the external monitor, there might be a graphics driver conflict with the laptop LCD display. Download and install the latest graphics and chipset drivers for your specific computer.

Step 4. If you can hear sounds of operation but no image is visible on either display, you can change a monitor or send the laptop for service.

Step 1. Turn off the laptop, and then disconnect the power cord. Before beginning any procedure, touch a grounded metal object to discharge static electricity.

Step 2. Remove the cover to access the memory.

Step 3. Remove memory modules on the laptop.
