3 Methods to Fix Lenovo Laptop Screen Dim Issue

But even so, you don’t have to worry too much. Here are three methods that can help you make your screen light up again:

Method 1 – Update graphics driver

In many cases, the culprit of dim laptop screen problem is the faulty graphics drivers. You need to update the graphics driver to the latest and correct version. But if you don’t have time, patience or computer skills to deal with drivers (since it is very tricky and time-consuming), we recommend you using Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
