Dell Inspiron 15, 3000 series. My laptop has suddenly started acting strangely. I may be typing, when suddenly when I press a key (say the key 's') instead of typing the letter 's' the screen changes to Settings. When I press other keys the screen changes to other applications. In other words from simply typing letters, the keys change their function.
Only change made which might have something to do with this: a change of location, from Europe to America. Remedy: when I restart system the problem stops. But this does not always work.
Another strange thing? When I access this website the items on the screen become greatly magnified - letters, symbols, everything.
