Arduino's IDE port option greyed out

I'm having a lot of trouble with my Arduino Leonardo Micro 5V. Basically, when I try to connect it to my laptop, I just can´t select any option for the port, because it's just greyed out. Most tutorials ask to update the Leonardo's driver, but my laptop doesn´t seem to have it.

I'm currently using an Arduino IDE 1.8.15.

Many thanks, Lucas.

You can't not do it though. The greyed out port almost certainly means no driver, maybe a few other things.
You're going to have to follow one of the numerous guides on how to install the drivers all the way to it's conclusion.

Thanks for the reply!

I definitively agree with you, but the problem is that when i search for that kind of instructions, I normally find this: Go to Device Manager -> Find the driver in Ports or COM -> Update it.

But i can't manage to find it. Seems like i don't have it there on Device Manager.
Perhaps, you know some guide that can help me?

Make sure the USB cable is completely plugged into both the Arduino board and the PC.

You may have a damaged/defective or charge-only USB cable. Try a different cable.

Either of the above can result in the power connections being made (and thus LED lights on the board), but no data connections (and thus no port for the board).

With the USB cable plugged in, double tap the RESET button (or short the RESET pin to GND twice if it does not have a button). The computer SHOULD then see something.

Hey, everyone.
Thank you all for the help, very nice solutions you brought for me.
In the end, my problem was not related to driver nor arduino IDE. I made a mistake by shorting many Leonardo's pins when I was using the solder, so was more a Hardware problem than Software.
I'll leave that reply here so if eventually someone get this problem, maybe this reply could help.
