What is it? Watch
What is this thing? and am I doing damage to the laptop when I fiddle with it? Slightly concerned as my dad is a total fascist when it comes to the laptop, and if I have done anything bad I am likely to be barred from the laptop til I'm 90.
I would be very grateful for any information/advice from computer minded people.
Don't worry - unless something pops out of the slot when you push the stick back in, then it won't cause any problems.
