I have an HP laptop running Window 10 home. On 5/28/18 I updated to Windows 10, version 1803.
When I am done on my computer, I don't shut it down, I just close the lid. When I open the lid, a lock screen comes up and I enter in my pin.
Yesterday when I opened the lid the screen was black and it was like that forever. I kept hitting the space bar and the left/right click on the touch pad, but it wasn't doing anything, and after hitting the button enough times, every time I pressed the space bar or touch pad or right/left click on the touch pad it would beep. But only when I pressed a button. This happened once before, and I pressed the power button and it woke up. I changed the sleep/hibernation settings and it never happened again. I don't know why it wasn't doing it before and all of a sudden did it that one time, but after changing the settings it never happened again until yesterday.
Since that happened, it has been working fine.
Today, I got on the computer and everything seemed fine. The only thing was in my mail app, it said my college email account was out of date, it said "Windows settings are out of date" when I clicked to fix it, I entered my password and it was fixed. I didn't think much of it because it's happened with my college email account many times before. Then, I worked for a bit, everything seemed to be working fine. After a while, I closed the lid and left for a while. When I came back and opened the lid, instead of the lock screen where I enter the pin, a blue screen came and said it needed to setup my Windows account and asked me to enter my Windows password, so I did. Then it asked me to setup a pin, as if I didn't have one already? But, I set up the pin, and then it went to my desktop with it just like normal?
Then, after working for a short amount of time, I got the alert in my mail app again that the Windows settings are out of date, but this time for a different account. I have not changed the password on this account, so I don't know why it would be out of date. So, I clicked to fix the issue. But, then it took me to a screen saying I would need to enable Hello Windows? Why would I need to do that. Every time I tried to cancel that out, it wouldn't work. Finally, after 3 times, I X'd out that screen and it allowed me to enter my password and said the issue was fixed?
I scanned for viruses and nothing came up - with Malwarebytes (free version) and with Windows Defender.
What could be going on?
