Does your screen remain blank or unresponsive after switching your laptop on? Learn how to solve common problems of your laptop screen that can occur at startup by reading this article. Before you begin to implement the steps, disconnect all connected devices except for the mouse. This includes removing USB sticks and memory cards for cameras in card reader slots.

Step 1 is listening to the noise made by the laptop and checking for light indictors. Do you hear the fans of the computer spinning? If you do not hear noise from the fans and the computer power LEDs are not lit, the problem is with the computer and not with the screen. Step 2 requires you to connect the laptop to another monitor in order to determine which of the devices has a problem. If you do not have a different monitor, temporarily connect your laptop to the monitor of a friend. If the replacing monitor works, your laptop screen is faulty and you need a new one. If the new monitor connected is blank, unplug it and go to step 3. If it displays the startup screen and then darkens, there is a problem with startup. Skip to step 5.

Step 3 implies inspecting all the cables and connectors to search for signs of deterioration. This means that you have to remove the laptop screen. Step 4 takes you to another level, and starting from here you should get specialized help, because it is possible for you to experience some difficulties. It consists of resetting and updating the BIOS. You can implement this step even if you do not see anything on the monitor. If such an update is not possible or the screen still does not display anything, go to the next step. Number 5 is disabling power settings in BIOS. If your operating system has recently undergone upgrade it is possible for your laptop to start in a saving energy mode and to display a blank screen before loading. Once the operating system loads (about 2 minutes after startup), press the power button to see if the computer resumes from suspended state. If the computer remains in a suspended state each time after startup, disable energy saving in BIOS.

As you have read, there are situations in which laptop screens need to be replaced or subjected to acts of service. You can contact the manufacturer for assistance if the device is in warranty or you can contact an authorized service center to assist you if it is no longer under warranty. Another solution is to look for an online shop which sells laptop screens of all types and brands and order a suitable screen. It is not very difficult to replace it yourself, and this way you can save a lot of money and time.

As you have seen, diagnosing and repairing laptop screens is not such a difficult job and with a little help almost anyone can do it. Don’t be afraid to explore this field of technology regarding a laptop screen.
