my laptop isn´t all that old, possibly no more than 9 months old, yet the keyboard gives me problems when trying to compose an email, replying to an aber thread. There i am on my 2nd line, when the keyboard decides to moves the words to the 1st line!! arrghhh.
Laptops tend to have a touch sensitive pad under (i.e. nearer you) the keyboard for use as a mouse substitute. They are easily touched when typing and a B nuisance. Defies all common sense anyone thought them a good idea. Try to find in the manual how to disable it.
