Hello! Few days ago while using my laptop I noticed a few dust particles in the keys and I could not stop myself from removing some of the keys and cleaning the dust. But when I tried to put them back, I could not. Initially I though it would be simple like a keyboard because it is very easy to remove a key and put it back in keyboard. So how do I put it back? Any tips, video links? Thanks in advance!

Hello! Sometimes when I log in from my laptop, it takes more time than the usual amount of time it takes to log in. After it logs in, the background is changed to black, the interface seems like the one from an old window like windows 98 and a message pops up on the bottom right corner of my screen. Following is the message "Failed to connect to a windows service. Windows could not connect to the System Event Notification Service service. This problem prevents standard users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond" I am a windows 7 user, any reasons why this happens with my laptop? Thanks in advance for help!
