Secure flash notification
What does this mean? I pressed a key as instructed, and my laptop turned on fine and is working normally, but this has appeared on my screen before. I've been trying to contact my local Dell repair shop for a few days now, but they haven't reached back out yet. They're insanely busy (it's always like this, unfortunately). Is this going to damage my laptop if I don't do something about it? Can I use my laptop normally? I mainly use it for uni, so I'm not really well-versed with the actual technological aspect of it.
I also recently noticed that some of the keys on my keyboard (specifically the ones that control the brightness) aren't working anymore, I can't adjust it even in the settings manually, it won't let me.
Any help would be appreciated!
