If you have a Lenovo laptop with a dim backlight and the desktop is weak but visible, it usually means that the main part of the motherboard is working properly.However, there may be a bad fuse, and in order to determine the part to troubleshoot, you need to identify one of the two LCD screens of the laptop CCFL and the LED style screen, if you have an LED-style screen, the reason is most likely that the fuse on the motherboard is blown.In most cases, newer laptops use the back of the LED styleThe light replaces the ccfl s, which eliminates the need for the inverter, so now the manufacturer is installing a fuse on the motherboard to protect the screen from impact.However, sometimes a brief problem blows the fuse away and causes a power outage to the screen that the computer is not able to use.However, with a little time and a lot of heat (welding), you can replace this puppy.Identifying the right fuse and replacing it will save you hundreds of pounds for repairs.Yourself, you may find a local store to do this welding, which is cheaper than replacing the motherboard.If you have a CCFL style screen (in short, it's a compact fluorescent bulb ).In this case it could be a bad inverter.The inverter is comparable to the ballast in the daily store lights, which raises the voltage in the laptop to a high enough level to allow it to emit fluorescence and provide light behind the screen.If you have any questions, please leave me a message and I have found many fuses on various laptops.If your model is not resolved here, please leave a linkPhoto of your board, I will see what I can find for you.
