Hello everyone!
I'm trying to use my old laptop as an air gap devices, how do I know if it's air gapped because I already used it before for internet connection but but it has been a very very long time and I also removed the wifi adapter so it can be er go online again.

Thanks for your help

You should also plan on how are you going to transfer the unsigned/signed transaction to/from your offline laptop.

After you install the new OS, and configure the way you want it, you should physically disable all
ports, USB, HDMI, Ethernet, SD card reader, Wifi/WWAN, etc.
(Unless you carry it around 24/7 and you sleep with it, LOL).

Use QR codes and laptop cameras to transfer the data between your air gapped computers.

You could buy one of these QR readers that do nothing but read QR codes, this way you minimize a lot of variables. I think you can find them for cheap on Amazon, just make sure they don't have any internal memory or wireless smart crap on them and you are good. Use these to read the raw transaction that you have converted into a QR code from the air gapped laptop in order to sign in in the hot wallet laptop. This way you don't need to move the laptops awkwardly in front of each other to read the codes. Also you don't want the screen of your cold wallet laptop to be visible at any moment to the camera of a computer that is connect into the itnernet.
