Step-1 Reseat Cables and Battery

First of all power off your laptop and close the LCD screen. Pull off the AC power and other cables connected with the laptop then flip over the laptop on a soft surface. Remove the laptop battery pack carefully.

Step-2 Clean the Battery Contacts

When you remove the battery from the laptop then you should have to clean metal contacts of the battery and also the battery bay. Sometimes tarnish may be cause to power down your laptop and due to low power LCD can’t show display. So you have to remove any dull that may seem on the contacts.

Step-3 Reinsert the Battery

  • After cleaning the battery, properly reinsert into its bay, ensure that you locked the battery in its bay then reconnect the AC power cord and other cables.
  • Turn your laptop on to check if it displays the image if the problem is still present then move forward to the next steps.

To make your laptop display OS normally, you should have three ways to follow:

  • Performing the hard reset
  • Connect an external monitor to check the display
  • Reseating the memory modules

Performing the hard reset

Several laptop issues can be resolved by resetting the hard disk. But before performing the hard reset make sure that you have backed up your all necessary data.

The hard reset will clear all the information from the laptop’s memory except any personal data. Performing a hard reset can fix different issues such as software freezing keyboard or mouse pad freezing a blank display and windows not responding etc.

Move onward to the next step if a hard reset did not resolve the problem.

Connect an external monitor to check the display

If the screen is still blank after performing the hard reset then it might be caused by corrupted graphics driver or a problem with LCD display backlight. You have to attach an external monitor to test the display.

To connect an external monitor with laptop first of all shut down the laptop and disconnect the AC adapter is plugged. Connect the monitor display cable to the VGA or DVI video output port on the laptop.

Even, there is no VGA port in the latest laptops available on market in 2019, but still, you can connect an external monitor with these laptops by using HDMI port. To connect external monitor through HDMI port you should have HDMI to VGA converter.

After connecting the external monitor with a laptop HDMI port, turn your laptop on. When you see the LED light appear on the laptop and hard disk starts to spin, press “Fn” key that sends the display to an external monitor. On some laptop keyboards, you have to press Fn + F4 key couple of times to send display on the external monitor.

  • If an image displays on the external monitor, it might be a graphics driver problem with the laptop LCD display. With the external monitor connected, install the latest display and chipset drivers for your specific laptop to solve the issue.
  • If the screen is still black after updating the drivers, the LCD might be defective. Contact professional hardware technician to resolve the issue.
  • If you hear the spinning voice of hard disk but no image displays on an external monitor, try the next step.

Reseating the memory modules

A loose memory module usually causes a laptop not displaying an image. So you can reset the memory modules to resolve several issues such as software freezing keyboard or mouse pad freezing a blank display and windows not responding etc.

Follow the steps below for reseating the memory modules:

  1. Turn off your laptop and disconnect the power cord.
  2. Flip the laptop over to it’s upside down.
  3. Find the memory module cover and remove it to access the memory.
  4. Pull up the memory modules from the memory bay.
  5. After cleaning the memory modules reinsert all of them. Replace the memory cover slot and fix with the screws.
  6. Connect the AC adapter to the laptop then Power on your laptop and perform any test to confirm that the laptop can start up and run in normal condition.

If the laptop fails to display an image on the screen, then contact with expert hardware technician to repair it.
