too late now, but when you get a new computer, put all the disks, manuals, paperwork, software, ... everything that comes with the computer in the box that the keyboard came in. Save the box someplace where you can find it. write the name of the system, model, year bought, etc. on the box.
you will swear that you will never need to read the manuals or use that stuff, but eventually you will, and you will have everything you need to get yourself out of a jam, all in one place.
