Keyboard lights are a common feature for many laptops and other electronics. If you’re anything like us, you always use your computer keyboard.
It’s likely one of your most-used pieces of hardware. And with that comes the risk of draining your battery. Keyboard lights are a common culprit for battery depletion.
They emit a bright light that can easily consume your battery life. This is why it’s essential to be careful when using keyboard lights they consume power and injure your eyesight in the process.
If you use a keyboard light often, consider buying a separate rechargeable model or investing in an LED light instead. Doing so will not only save your battery life but will also improve your typing experience.
Do Keyboard Lights Drain Battery?
Turning on the backlight of your laptop’s keyboard will certainly affect battery life. When you are using a keyboard, the backlight will turn on to illuminate the key.
This light uses very little power, so it is usually not a drain on your battery. However, if you have an especially bright backlight or keep the keyboard turned on all the time, it can use up a bit of juice.
If your battery starts to run low and you notice that your keyboard’s backlight is draining it quickly, you may want to adjust the brightness or turn off the keyboard altogether when not in use.
Most keyboard backlights use very little power, so they are usually not a drain on your battery. However, if you have an especially bright backlight or keep the keyboard turned on all the time, it can use up a bit of juice.
When your battery starts to run low, and you notice that your keyboard’s backlight is draining it quickly, you may want to adjust the brightness or turn off the keyboard altogether when not in use.
How To Fix A Keyboard Light Drain Issue?
There are a few things that you can do if your keyboard light drain issue persists. The first is to make sure that you’re using the right kind of keyboard light. Different keyboards use different kinds of lights, and some lights may not be as efficient as others.
For example, if you’re using an older keyboard, it might not have any bright light LEDs and instead might only use a backlight.
Unfortunately, this means the light will drain your battery more quickly than if you used a newer, more efficient keyboard.
Another thing that you can do to try and prevent your keyboard from draining your battery is to turn off the light when you’re not using it. This way, the computer will only need to spend as much power keeping the light on.
Additionally, if you have a laptop, try to keep the lid closed when you’re not using it so that the computer doesn’t need to keep pumping out heat to stay calm.
If none of these fixes works, then consider replacing your keyboard. Keyboard lights consume a lot of power, and if they need to be fixed, then they may be causing problems elsewhere in your computer.
Why Is LED Backlighting Popular On Laptop Keyboards?
LED backlighting is a popular choice for laptop keyboards because it consumes less power than traditional backlighting methods. LEDs use very little energy, so a keyboard with LED backlighting can last longer on a single charge.
Additionally, because LEDs are smaller and more efficient than traditional lightbulbs, they create less heat and don’t require as much space on the keyboard. This means laptop keyboards with LED backlighting are thinner and easier to fit into tight spaces.
One disadvantage of LED backlighting is that it is not as bright as traditional backlighting and can be difficult to see in dark environments. Additionally, some people find the blue light emitted by LEDs to be intrusive or unpleasant.
Should You Turn On The LEDs On Your Laptop?
A few things are more frustrating than trying to work on your laptop and realizing that the backlight isn’t turning on. So, does turning on the backlight use up battery life?
The short answer is that it depends. The backlight will use up a small amount of power, but turning it off entirely can drain your battery faster.
This is because the backlight is essentially just a light source, and like any other light source, it uses energy to create its image.
The amount of power used to create this image will depend on several factors, including how bright the backlight is and how long it’s been turned on.
Turning on the backlight will use up about 0.002 watts per hour (W/H), while leaving it off will use about 0.004 W/H.
So if you’re using your laptop for an hour every day, turning on the backlight each time will add up to about 2 watts over a month (8W). Turning it off would save about 4 watts over a month (16W).
So, turning on the backlight will use up a small amount of power. However, depending on how often you turn it on and how bright the backlight is, it can use more or less power.
So if you’re concerned about conserving battery life, it’s best to turn off the backlight when you’re not using it.
What Are The Best Options For Finding And Fixing A Keyboard Light Issue?
There are a few different ways to find and fix keyboard light issues. Start by checking the battery life of your keyboard. If the light is not staying on, it may be due to a low battery.
To check the battery life of your keyboard, open the Windows “Power Options” and select “Change Plan Settings.”
Then, under “Hardware,” click on your keyboard’s name and in the “Device Status” column, look for a number next to “Battery Life.” If it’s below 50%, you should replace your battery.
If the light is not staying on even when the computer is off, it may be due to a broken or malfunctioning circuit board.
To test if this is the case, remove one of the light bulbs from your keyboard and hold it close to an outlet while turning on your computer.
If you see a blue or white light coming from the bulb, electricity will likely flow through the circuit board. If this is the case, you will need a professional repair or replace your circuit board.
