Dell Latitude E7440 Stuck in Flight Mode

[lanaeve]

My younger sisters laptop recently got stuck in flight mode after she was playing the Sims 4 for a while (apparently).
When you try to turn off flight mode, it just turns itself back on again.
We've tried

fn+f2
Resetting with files
Full reset with disk clean

Since completely resetting the computer didn't work, I'm assuming it's a problem with the Dell drivers. But I have no idea how to fix them.

Any help would be appreciated!

Hi, often you can look it up in the manual to see if there is a way to turn Wifi on or off with a button or keyboard. When Wifi is turned off, the laptop will be stuck in Airplane mode.
