You boot files could be damaged. Try booting up in Safe mode. To boot in to Safe Mode. Press the F8 key while booting up and you will get a list of booting options. Choose the Safe mode. If you are able to boot up in Safe mode, then the next normal boot should solve the issue.

The process of removing and replacing the keyboard involves disassembling the entire computer. I do it all the time -- not usually something the average user would want to tackle.

if you want to shutdown your laptop automatically go to power option from control panel and from there you can schedule the time after using how many minute or hour you would like to automatically shutdown your laptop. Try it !! Good luck.
