On a laptop, if you press the key that turns on/off the backlight on the keyboard, does it improve battery life?
I ask this because I find myself instinctively disabling the LEDs when I don't need them, but I don't know why I do it.
Other than improving visibility at night, I don't see any advantages of having them on other than "it looks nice". But, I also don't see any disadvantages to them being on. In theory, it makes sense to just have them on full time.
If they're off, I really don't see how something so small can make a significant battery impact. Which brings me back to my question: does disabling the LED backlight on a laptop keyboard improve battery life?
Thanks!
P.S. I mean the backlight on the keyboard, not CapsLock and NumLock indicators.
Every additional device that uses power is going to reduce the time a battery charge lasts. Whether that time difference will be "significant" is up to you to decide. – Ƭᴇcʜιᴇ007 – 2017-01-18T20:58:27.097
The LED's are so small and use so little power that you would not notice any gain in your battery life. When someones battery is low, you don't see them turning off their keyboard backlight. You'll have more noticeable results by reducing something like the screen brightness. – DrZoo – 2017-01-18T22:07:23.713
