HP laptop goes into AIRPLANE mode after suspend.How to fix it?

Question

I recently added Ubuntu 18.04 alongside Windows 10 to my laptop (HP pavilion 15 ab032tx). Everything works fine except:

When I close the lid, then later reopen it, Ubuntu goes into airplane mode and F12 to clear airplane mode does not work. I have to reboot the laptop to reestablish WiFi.

I have tried resetting my BIOS settings which did not solve the problem.

Result of rfkill --output ID,TYPE

ID TYPE   
 1 wlan

How may I troubleshoot this to solve the problem?

does your laptop have a hardware switch? There are a couple of questions that may be related to your topic and perhaps there is already an answer here. See: search results of "suspend airplane" sorted by votes. Can you look through these and come back and make an edit with the results of your research and attempts to fix (and the outcome of those attempts) — Nmath, Mar 06 '20 at 18:21
@K7AAY there is no problem as such in my Windows 10. Only in ubuntu — Shyamal Jyoti Buragohain, Mar 06 '20 at 18:42
I think it may be something in your settings. You can adjust that in your Ubuntu 18.04 settings application, in the internet/communications one. It is not labeled that way. — Logan, Mar 06 '20 at 18:43
@Jeff I tried turning ON the WiFi from the settings but no luck. — Shyamal Jyoti Buragohain, Mar 06 '20 at 18:46
Please try rfkill unblock wlan again - and http://askubuntu.com/editing-help#code shows how to use formatting in questions — K7AAY, Mar 06 '20 at 18:52

So, I found a WORKAROUND of the problem by simply changing how my laptop responds to lid closing. Simply, use the command
sudo sh -c 'echo "HandleLidSwitch=lock" >> /etc/systemd/logind.conf' && reboot
It will now LOCK the computer every time lid closes instead of suspending and hence no problem of AIRPLANE MODE.

In case it's still useful, I've been struggling with the same for years. I probably tried every fix suggested online, everything that seemed to work for someone just didn't have an effect locally. After long struggling I just accepted that there's no actual fix online. Deep inside I just couldn't really believe it, though, I couldn't understand why it would work under Windows but not under Linux, so from time to time I had another look online. I also did the lock-fix long ago, but didn't really like it; closing my laptop, putting it in my bag for a couple of days while forgetting that it was actually not suspended or shut down, and having an empty battery when wanting to use my laptop again :-)

In any case today I seem to have found a fix here, wich worked for me: Wifi Hard Blocked After Suspend in Ubuntu on GS65

Despite their post not being for an HP, it fixed it for me locally nonetheless. According to this link, I understand that their suggested fix is "lying to the BIOS, making it think it's running Windows"? It feels like a weird solution (makes sense in a way, but then again, still feels weird), and I've only used it for a couple of hours. Who knows what I will discover in the next few days/weeks/months, I feel like that fix could show some surprises along the way ... YMMV but just in case it helps, I wanted to put that fix out there!
