Airplane mode stuck AND can't sign in

Don't know how this happened but I accidentally turned airplane mode on, and it's stuck ON. Not only that, but whoever that happened, my laptop got rebooted with airplane mode on and now I can't even log into my

Microsoft account because I'm offline. It's in Inspiron 16 that decided to b upgrade to Windows 10 for me one day.

I've been reading up on this and I'm seeing tons of people are having the same issue with airplane mode/WiFi, but I'm the only doofus who can't even log in to get to any other options from a task bar.

I've pushed the Wi-Fi tower/PrtScr button many different times paired with Fn and other random combos to no avail. I've shut it down, taken out the battery, held on the on/off button for 20 seconds, put battery back in -- nope. I've checked and there is no external button. Airplane mode bar is greyed out and not budging.

I really don't know anything about cards or hard drives and what have you, I just made a mistake and after months of ditching it, thinking maybe I didn't really need a laptop anyway, I'm back trying to fix it without a clue in the world. Is there ANY way to fix this if it won't even let me log in because I'm offline or do I need a new laptop now?
