After upgrading an older Lenovo laptop to Windows 10 recently, I ran into a very annoying problem. For whatever reason, the ability to adjust the brightness stopped working. Pressing the brightness keys on the keyboard would show that the brightness level was going up or down, but nothing actually changed on the screen! It was the weirdest thing I had ever seen.

On a MacBook, look at the top-left corner of your keyboard. The F1 and F2 keys will decrease and increase your brightness. On a Mac desktop PC, look at the top-right.

Here's how you can use a quick keyboard command to give you finer control over the screen brightness of your Mac. Press and hold the Shift and Option keys.

The first thing I thought was maybe there was some hardware issue and Windows 10 was not recognizing the key press properly. I decided to try to change the brightness level in the OS itself. I opened Action Center and clicked on Expand and then tried to adjust the brightness there, but again nothing happened! Now I was really confused.

I also tried to go to Power Options and change the brightness there, but again it didn’t make any difference on the actual display. The second thought that popped into my head was that it was a driver issue. I went to the Lenovo website and downloaded the latest driver I could find for the machine. I was hoping that would fix the problem, but it didn’t!

At this point, I figured it could be that the latest driver doesn’t yet support Windows 8.1 properly and therefore I need to try out the standard or basic Windows graphics driver instead. In the end, this is what fixed the problem. Now I just have to wait till Lenovo releases an updated driver for my older Lenovo laptop. Here’s how to fix the issue temporarily.

First, open the Control Panel and click on Device Manager:

Next, expand Display Adapters and then right-click on the graphics card installed on your system and choose Properties. It could be something like Intel HD Graphics, etc. It’ll depend on what kind of graphics card you have installed, but there really should only be one or two listed max.

Depending on your system, you may see several drivers listed in the box, even the same driver listed multiple times. You can try some of the other ones, but if nothing works, just use the basic driver. Unfortunately, you won’t be able to run the OS at the highest resolution or frame rate if you use the basic driver, but at least you can adjust the brightness.

In my case, I simply switched to the basic driver, adjusted the brightness to where I needed it and then switched back to the original manufacturer driver. The brightness level remained at the level I had set it, so that was good. Then just check every so often to see if there is a new driver and install that when it becomes available.
