If you are new to the world of modern computing, you may wonder why your mouse light is on when the computer is off. Even the best computer mouse in the whole universe can fall victim to this issue, leading to confusion. So what causes a mouse’s light to stay on when the computer has been powered down, and how can you fix it? Keep reading to find out.
The mouse light stays on for any number of reasons, similar to when wondering why you can’t see a mouse on the computer. The underlying issues here can be software or hardware-related, even if you have learned how to use two mice with one computer. In some cases, a battery is to blame, even if you have learned the definition of a PS2 mouse. In other cases, a dirty and activating workspace gets in the way of you conducting that PS2 vs USB mouse review.
You should also try replacing the batteries (if it uses standard AAAs or AAs) or charging the battery.
Let’s troubleshoot this issue. There are a few different things worth trying that could resolve it in no time.
The first thing you should do is clean your workspace. Why do this? A dirty workspace is filled with debris. This debris could fool your mouse into thinking that it is needed even when it is not, particularly if the debris creates the illusion of an uneven surface. Clean the workspace thoroughly to remove any hint of debris. Don’t forget to clean the mousepad here; if it is too old to use, feel free to toss it. They are, after all, rather inexpensive.
Since you are already cleaning, keep going and clean the mouse itself. It is very likely that the mouse ran over dust and debris that, in turn, spilled into the interior components, thus tricking the mouse that it is always on, even when it should be powered down. Give it a good cleaning with a microfiber cloth and a dedicated cleaning solution that won’t fry the electronic components.
STAT: The first public demonstration of a mouse controlling a computer system was in 1968. (source)
