I dropped my laptop a very short distance whiles in a laptop sleeve- the brightness can no longer be adjusted?

If it was running (HDD was spinning), start watching for HDD errors. The first sign of any HDD error (or SMART warning), you will have to change the drive. I would suggest a full backup right now, to be on the safe side...just in case... The only thing, besides physical damage to the outside, is the HDD which is a spinning, moving part.

Dropping that can cause severe errors or failure.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
