Laptop computers are the complex systems compared to the normal desktop computers due to the size and complexity of the internal circuitry. Among a lot of problems, screen problem is the most irksome to face. I faced the black screen problem several times. I am sharing my experience what to do when the laptop screen goes black. If you fall into the hardware problem then it will be better to take the laptop to the service center shop. If it is a software issue, then try to fix it yourself.
To find out the screen problem is not easy. There are a lot of reasons for which your laptop screen can become black. There are several software and hardware issues. I will try to identify the main points.
1. Check out the Sleep or Hibernate Mode Timer. Your laptop computer can be programmed to run in hibernate or sleep mode. There can be a timer, set up for the hibernate mode, or sleep mode, which makes the laptop off temporarily. In this case, the screen goes black. Again, it can be happened that you have set the timer in a very short time interval of few seconds. So the screen becomes black too often. For this reason, check the sleep mode or power settings of the laptop and solve the problem.
2. Almost all the hardware parts of computer need software drivers to work well. If your graphics driver of laptop is damaged or corrupted then it can cause problems of screen going black. If this is the problem, then update your graphics driver and install it again.
3. FL inverter controls the back lighting of the laptop. If you connect the laptop with external monitor and it goes well, but sometimes the screen becomes black then you should isolate the inverters as the main reason of problem. Ask the service center for this issue and replace the part to solve this, if needed.
4. There is another hardware part of laptop which passes the graphics data into the screen in the form of data ribbon. This can sometimes cause a great problem. If the data ribbon becomes bad or ribbon connection becomes loose then the laptop screen can become black. You will have to check it taking the laptop to service center. Sometimes this problem can be happened for the overheating problem and low battery power. Making the laptop cool and providing sufficient amount of charge to battery, this problem can be solved.
I hope you know the right steps now when the laptop screen will go to black. If you still get into difficulty, go to expert without late. It will be the best idea.
