So yesterday I went on my laptop as per usual and noticed that all of a sudden I wasn't connected to the WiFi. I then saw that it was on airplane mode so when I tried to turn that off it wouldn't and still won't, I searched up almost every kind of way to turn it off and it won't. Then I thought I'll just reset my laptop but then that won't work because it just said something like it could not be reset no changes were made and believe me I've tried so many things to fix that with no luck, I've also tried booting it into safe mode but I also have the same issues in there. Also the sound and brightness cannot be changed and I'm sure there are many more things that don't work that I haven't discovered yet. Also I forgot to mention that I did try to use the internet by plugging in the ethernet cable because that has worked before but it didn't. I have no idea what's going on please help!!
