Lenovo laptop, recent character?

By chance someone can help me, I have had a strange sign (see picture) on my laptop for some time. The problem is it doesn't go away. I'm afraid it's a virus, it's my only laptop, if it's gone, I won't have any more to prepare for my exams.

I hope someone knows about it.

Thank you in advance.

Kind regards

Maybe it means that your laptop is not connected to Wi-Fi?!

The sign means - no internet… None, neither Wi-Fi nor lan…

You are not connected to the internet with your laptop.
This is the sign to inform the user.
To fix this, turn on your WLAN on the laptop and enter your router password.
Alternatively, I would connect a LAN cable through an Ethernet socket. Then you can save yourself that with the password, but you are then wired.

If I enter this with the router, then my WLAN does not work, I don't know either, because I enter the necessary data, that's why I've been using an Ethernet cable for almost a year…
