There isn’t just one way to turn on your keyboard lights. It can vary wildly among laptop and peripheral manufacturers and even among different laptop lines from the same brand.

To bring a bit of clarity to the situation, we’ve gathered together seven possible ways to turn your keyboard backlighting on or off. Read on to find the best method for your laptop or desktop keyboard.

Press the dedicated button for keyboard backlighting

Some keyboards, like the Logitech G Pro desktop keyboard, will actually have a dedicated button that you can press to toggle the keyboard light on or off. In the case of the Logitech G Pro, you’ll want to look for a button stamped with a sun icon with rays in the upper-right corner of the keyboard.

Press the Increase Brightness button

If you have a MacBook, certain models allow you to turn on the backlighting by pressing the Increase brightness key, which looks like half of the sun with three rays. Press it until you get the desired level of keyboard light brightness. To turn it off, press the Decrease brightness key, which looks like a half-circle outlined in dots (instead of the rays) until the light turns off.

Using the Increase/decrease brightness buttons should work for certain models of Macs that run macOS Sonoma, Ventura, High Sierra, Mojave, Catalina, Big Sur, or Monterey.

Press the assigned Function key

For many Windows laptops, you might need to press a Function key (F1 to F12) to turn on your keyboard’s backlighting. If this is the case, which Function key it is will likely depend on the brand and model of your laptop.

For example, Dell notebook PCs have at least three possible key options: F6, F10, or the right-arrow key. In some cases, F5 is also possible. From these options, you should be able to tell which one controls the backlighting by seeing which one has the Illumination icon (which looks like a half-sun with rays) stamped on it. If you don’t see this icon at all, your Dell PC doesn’t have keyboard backlighting. But if you do see the icon, press the Function key that has it. (You may need to press it in conjunction with the Fn key.) Pressing that key combination – Fn + the function key – should allow you to cycle through various brightness level options for your Dell PC’s keyboard, so keep pressing it until you reach your desired brightness level or until you turn it off.

HP notebook computers work similarly to Dell laptops: You’ll need to press an assigned Function key (which could be F5, F4, or F11) with or without pressing the Fn key as well. You may need to press it multiple times to adjust the brightness or turn it off. There should also be a backlight icon stamped on the assigned Function key for your HP notebook that looks like a row of three dots with rays coming out of the first dot.

The main thing, though, is that if you don’t know the keyboard shortcut or Function key assigned to your keyboard’s backlighting feature, you should look it up in your PC’s manufacturer’s support site or manual to find out.

Use the Touch Bar

Certain MacBook models may have you adjust your keyboard lighting via the Touch Bar instead. To do so, tap the Arrow icon on the Touch Bar to expand its Control Strip. To turn on backlighting, tap the Increase brightness button. To turn it off, tap and hold the Decrease brightness button, which looks like a half-circle outlined in dots, not rays.

These instructions should work for MacBooks with Touch Bars that run MacOS Sonoma, Ventura, Monterey, and Big Sur.

Adjust it in Control Center or Windows Mobility Center

Depending on the manufacturer and model of your device, you might be able to turn on and adjust the keyboard light via your PC’s control panel menu.

For certain MacBooks, that means opening Control Center, selecting Keyboard brightness, and then dragging its corresponding slider. This should work for some MacBook models that also run MacOS Monterey or Big Sur.

For some Windows 10 PCs, this means you’ll need to access the Windows Mobility Center, which resides in the Control Panel. To access it, select Control Panel > Hardware and sound > Windows Mobility Center. In the Windows Mobility Center, look for the Keyboard brightness (or Keyboard backlighting) setting, select its corresponding slider, and pull that slider over to the right.

Use the keyboard’s recommended software, if available

Some keyboards have their own specific software or app that can be used to control and customize the settings of your laptop or desktop keyboard. A great example of this is the app used for Razer’s laptops and peripherals: Synapse. The Synapse app can be used to customize the lighting effects of your Razer gaming laptop’s keyboard or your Razer desktop gaming keyboard. And this can include increasing or decreasing the brightness of your keyboard light or adjusting the settings so that the light stays on or off in sleep mode.

Most of the best gaming keyboards have some kind of back-end software that can let you adjust the RGB lighting of individual keys or turn any or all of them on or off at will.

Enable keyboard backlighting in the BIOS

In some cases, if your laptop has the right keyboard light buttons and they still don’t work the way they’re supposed to, it’s possible that you may need to check your device’s BIOS settings and make sure that they’re configured correctly, or your BIOS may need to be updated to the latest version. When doing either of these things, be sure to follow your device manufacturer’s instructions on how to do it carefully. Look up those specific instructions first. Some manufacturers like HP or Dell have posted detailed instructions online on how to check for these issues and/or correct them.

Frequently asked questions

Why won’t my keyboard backlighting turn on?

There are a number of reasons why your keyboard backlighting won’t turn on. Here are a few you may want to consider:

• Your device may not actually offer a backlit keyboard. Not all laptops or desktop keyboards have keyboard lights. Check with your device’s manufacturer to confirm that the model of your device is supposed to have backlighting. If it is, confirm that you’re using the right keyboard shortcuts, buttons, or settings to turn it on.
• Some laptops like MacBooks use light sensors for backlighting in low-light situations. It’s important to know where they are on your device and to make sure you’re not blocking them.
• Is the backlight not working or is the brightness level set too low? If the brightness level of the backlight is set too low, then the light is probably working but you’re just having trouble seeing it. See if you can increase the brightness level using our suggestions above so you can see the light better.
• You may need to update the BIOS to the latest version, or its settings aren’t configured correctly. If you decide to update the BIOS to the latest version or reconfigure its settings, be sure to follow your device manufacturer’s specific instructions for doing so.

Does keyboard backlighting drain the battery?

Yes, keyboard backlighting can contribute to the drain, as it does need power to function. If you’re concerned about conserving battery power, you can turn off the backlighting or adjust your keyboard lighting settings so that the light automatically turns off when the computer goes to sleep or the display is off.

How do I change the keyboard backlighting color?

First, make sure that your keyboard has the ability to change backlighting colors. If so, you’ll need to consult your device manufacturer’s specific instructions on how to change the backlighting color. Usually, these instructions will involve you opening a manufacturer-recommended desktop app like the HP OMEN Command Center or Razer’s Synapse app and then customizing your lighting settings within that app to add colors to your backlight.

Apple just upset everyone, claiming that the 8GB of Unified Memory available in the base MacBook Pro M3 is “probably analogous to 16GB on other systems.”

The MacBook Pro M3 has already come under fire for only including 8GB of Unified Memory in its base configuration, which runs $1,600. MacWorld recently ran a story criticizing the 8GB of memory in the MacBook Pro M3, saying, “If 8GB will be a bottleneck for many today, imagine the performance of that non-upgradeable laptop in a few years’ time.”

Apple’s response is that 8GB on a MacBook Pro M3 is probably closer to 16GB on a Windows laptop. In an interview with Lin YilYi, Apple’s Bob Borchers addressed the 8GB of memory in the MacBook Pro M3:

“Comparing our memory to other systems’ memory actually isn’t equivalent, because of the fact that we have such an efficient use of memory, and we use memory compression, and we have a unified memory architecture. Actually, 8GB on an M3 MacBook Pro is probably analogous to 16GB on other systems. We just happen to be able to use it much more efficiently … I think this is a place where people need to see beyond the specs and actually look at the capabilities.”

Borchers has a point. Due to the fact that the MacBook Pro M3 uses a system-on-a-chip (SoC), it’s able to access memory much more efficiently than a standard Windows laptop. Capacity and speed are two sides of the same coin; if you have faster speeds, you don’t need as much capacity, and vice versa.

In addition, Apple includes a 512GB SSD with the base MacBook Pro M3, which uses two NAND chips. The previous version showed much slower SSD speeds with only a single NAND chip, and due to swap memory being critical in memory-limited situations, the 256GB SSD combined with the 8GB of memory vastly reduced performance. MaxTech’s early testing on the MacBook Pro M2 showed how big of a problem the 8GB of memory combined with the 256GB, single NAND SSD really was.

In real use, that shouldn’t be as big of a problem on the MacBook Pro M3. Unified Memory allows Apple to get away with lower capacity compared to Windows laptops, and the dual-NAND configuration of the SSD keeps things from being too slow when swap memory comes into play. The problem isn’t 8GB of memory, or even that it comes on a $1,600 laptop in 2023. It’s that adding more memory costs so damn much.

You’ll spend an extra $200 for 16GB of memory and an extra $400 for 24GB. Even ignoring the cost of those memory modules — I’ll let you know it’s far less than what Apple’s charging — you can see how big the upcharge really is just from configuration options. In Apple’s mind, each 8GB module of Unified Memory is worth $200. That’s insane.

If you look at a laptop like the Dell XPS 13 Plus, which comes with 16GB of memory for $1,500, you can upgrade it to 32GB for an extra $150. There’s no issue with Apple selling the MacBook Pro M3 with 8GB of memory, even for $1,600. But it shouldn’t cost an extra $200 just to get to 16GB for users who truly do need that extra capacity.

This really isn’t anything new for MacBooks, though, and it doesn’t just apply to memory. If you look at storage options, you’ll need to spend an extra $200 to upgrade the 512GB SSD to a 1TB SSD, and an extra $600 to upgrade the 512GB SSD to a 2TB SSD. Once again, each 512GB chunk of storage is worth $200 in Apple’s mind, despite the fact that the cost for these components isn’t anywhere remotely near that price.

It could go either way — Apple should have the base MacBook Pro M3 with 8GB of Unified Memory sell for a lower price, or it should make the cost of upgrading to 16GB of RAM much cheaper. It doesn’t really matter if you need that memory or not, either. The upgraded model is the one most people should buy, even if they only occasionally go over capacity.

At the very least, that pricing scenario would be a minor annoyance, with Apple nickel and diming people to get the RAM they need (definitely not uncharacteristic of Apple). As it stands now, with the high base price and huge cost of upgrades, it is hard to say the MacBook Pro M3 truly starts at $1,600 when a critical upgrade is locked behind a $200 paywall.
