How To Change Keyboard Color On Lenovo Laptop

For months, my Lenovo Yoga C940 laptop seemed to be playing tricks on me.

1 minute the display would be pleasantly bright, but switching to anything with a dark background acquired a gradual driblet in contrast, giving the screen an nigh grimy advent. I could even see the change boot in while switching between applications, every bit if some motorcar-brightness setting were constantly going awry, yet the Windows Settings carte offered no obvious solutions.

Eventually, though, I found the source of the problem. Tucked abroad in recent Intel-powered Windows laptops is a programme called Intel Graphics Command Heart, containing a sprawling assortment of virtual knobs and dials for adjusting the look of your laptop's screen. After making some small adjustments inside this program, my laptop's effulgence bug were gone.

My Lenovo Yoga isn't the only Windows laptop with these kinds of bug. Equally a laptop reviewer for PCWorld, I've besides experienced auto-effulgence problems with several other Lenovo laptops, and with the Razer Book thirteen. If you're having motorcar-brightness issues on your Windows laptop, this might exist the solution y'all seek.

In any example, Intel's Graphics Command Eye app is worth a expect. By playing with its various color and contrast options, you can make your laptop'south screen look better than it did out of the box.

How to set up Windows auto-brightness problems

To launch the Intel Graphics Command Middle app in Windows 10, just click the Start button and type Intel, which should bring up Graphics Command Center as the kickoff pick. Alternatively, y'all can find information technology by scrolling down to the 'I' section in your alphabetized app list.

intelcommandcenterlaunch — If y'all accept a recent laptop with Intel within, the Graphics Command Center app should be pre-loaded.

When you start launch the app, Intel will advertise a couple of gaming-related features. Simply ignore these and instead select the Organization tab on the left sidebar (or, if the app is running in a small window, the icon that looks similar four squares). At the top of the screen, select the tab that says Power.

intelcommandcenterchange — Intel's Power Efficiency setting can cause drastic contrast changes depending on what's onscreen.

To stop your laptop from changing contrast levels on its own, look in the Ability Settings section and change the Power Efficiency level to i.

You can also plough off all of the power efficiency settings in this bill of fare, along with the Dynamic Refresh Rate Switching or Extend Battery Life for Gaming options at the peak, but I've establish that simply reducing the aggressiveness of Intel's image viewability slider does the job well plenty.

Will changing these settings drain your laptop's battery? Non at all. In fact, my testing showed that dialing downwardly Intel's power efficiency settings led to an increase in battery life.

My outset test involved looping the open-source 4K video Tears of Steel—the same video we use in PCWorld's battery rundown test—at maximum brightness with no sound on my Lenovo Yoga C940. With Intel'southward Power Efficiency setting at its default level 4, the laptop lasted x hours and 36 minutes. With the Ability Efficiency set to level 1, the laptop lasted 10 hours and 53 minutes.

I as well created a video of my own to simulate the kind of contrast fluctuations that had bothered me so much to brainstorm with. This video captured my desktop screen as it flipped between calorie-free and dark backgrounds every ten seconds. In that test, the laptop ran for xi hours and 9 minutes at Intel's default Power Efficiency level 4, only lasted a whopping 12 hours and 46 minutes with Power Efficiency level 1.

Increasing the Ability Efficiency level is supposed to reduce paradigm quality, thereby increasing battery life, but in my instance the opposite was true. While your mileage may vary by laptop and use case, information technology's prophylactic to say that Intel's power efficiency software doesn't meaningfully ameliorate bombardment life. It may even be counter-productive.

PCWorld reached out to Intel for annotate, and received this statement: "Intel Display Power Saving Technology (DPST) reduces power consumption on mobile PCs past reducing backlight of the laptop panel while maintaining quality on screen. Users might notice this result at piece of work when switching between applications and media when in battery mode. Our OEM partners are enabled to change the default behavior for DPST as they see fit. In some mobile PCs, DPST can be disabled in the Intel graphics settings. Over time nosotros will continue to improve the performance of DPST to provide better mobile experiences."

How to adapt your laptop'south color and contrast

Equally long as you're checking out the Intel Graphics Command Center app, have a minute to visit the Display tab (or click the computer monitor icon when the app is running in a small window). From hither, click the Color tab, and you lot'll run across a menu for adjusting your display's brightness, contrast, hue, and saturation.

intelcommandcolors — Intel's app also lets you fine-tune display colors, only like y'all would on a TV.

Before yous starting time trying to make whatsoever adjustments, click the Custom push at the tiptop to create a new color profile, then requite the profile a proper name. Now, try making adjustments to the effulgence, contrast, hue, and saturation levels in this menu. Toggling the All Colour pick for brightness and contrast lets you adjust individual color intensities as well.

I've found that less is more, and that just a few tiny tweaks can make a large improvement in how your screen looks. If yous always want to restore your calculator'southward built-in settings, but click the Default box at the height of this menu.

intelcommandcolors2 — Make certain to whorl to the bottom of this bill of fare for hue and saturation options.

The Intel Graphics Command Center app has another options, such as a video-specific movie settings menu, a capture tool, and the ability to set keyboard shortcuts for screen rotation. You tin can safely avoid these, equally none of them are nearly equally useful as the app's power settings and color options.

To be clear, none of these settings are new. Intel Graphics Command Center launched a couple of years ago equally an development of Intel's one-time Graphics Control Console. Intel says information technology's supposed to exist much simpler to use and understand.

Unfortunately, Intel and PC vendors seem to have gotten a chip carried away in their zeal for better battery life, pre-loading laptops with power management settings that do more impairment than skilful. If you've started to suspect that your ain laptop is playing tricks on you lot, dialing back those settings merely might be the answer.
