But don’t worry, there are a few things you can do to try and fix it. In this blog post, we’ll outline some of the possible solutions to Lenovo laptop screen goes black when plugged in. So read on to learn more.
Reason
One possible reason for this issue is that your laptop’s display settings may be set to dim the screen when it’s plugged in. To check if this is the case, go to your laptop’s Control Panel and click on “Display.” Then, look for the “Dimmed display when connected to AC power” setting and make sure it’s turned off.

Method
If your Lenovo laptop screen goes black when plugged in, it is likely that there is an issue with the power supply. To resolve this, you can try the following:
- First, check that the power cord is firmly plugged into both the laptop and the outlet. If it is not plugged in securely, tighten the connection and try again.
- If the power cord is plugged in securely and the screen is still black, try plugging the cord into a different outlet. If this does not work, the power cord may be damaged and will need to be replaced.
- If the power cord is not the issue, there may be a problem with the battery. Try removing the battery and plugging the laptop in to see if the screen turns on. If it does, the battery may need to be replaced.
- If the screen still does not turn on, there could be a problem with the laptop’s display. Try connecting the laptop to an external monitor to see if the screen is displayed on that monitor. If it is, the problem is with the laptop’s display and will need to be repaired or replaced.

If your Lenovo laptop screen goes black when plugged in, there are a few things you can try to fix the issue. First, check to make sure that the power cord is plugged in securely and that the outlet is working. If both of these things are fine, then it’s possible that the screen itself is defective.

Causes Of A Black Screen On A Lenovo Laptop
There are several causes for a black screen on a Lenovo laptop. The most common cause is simply that the backlight has failed. Other causes can be a loose connection between the LCD panel and the inverter board, or a faulty inverter board.
If your Lenovo laptop has a black screen, the first thing you should do is check the backlight. If the backlight is not working, the screen will appear black even when it is on. To test the backlight, hold a flashlight up to the screen. If you can see the image on the screen clearly, then the backlight is not the problem.
If the backlight is working, the next thing to check is the connection between the LCD panel and the inverter board. If this connection is loose, it can cause the screen to go black. To check the connection, simply unplug the laptop from the AC power adapter and then plug it back in. If the screen comes back on, then the connection was loose and is now fixed.
If the screen does not come back on after checking the backlight and connection, then the problem may be with the inverter board. This board supplies power to the backlight, so if it is faulty, it can cause the screen to go black. The best way to test the inverter board is to replace it with a new one.
