Can the laptop work without a WLAN board?

Can the laptop work without a Wi-Fi board?

Which laptop? And what do you mean by working?

Do you notice when you remove the small plug-in card with the Wi-Fi module?

Yes, that is of little interest to the computer. Then you have no WLAN / Bluetooth anymore.

Acer e5-575t with working i mean that the windows loads

Thank you very much

Of course, it will no longer have Wi-Fi / Bluetooth, but it should still be running.

One more question, my laptop is not working properly, after switching on the screen flashes, and ram becomes very, very hot that I can no longer touch it, what can that be?

Blinking black screen, so the windows is not loading
