I wouldn't panic too much. Out of millions and millions of laptops sold this appears to have happened to a very few. If you fancy your chances of winning the lottery, then get worried.
If you have one of the affected laptops, get it fixed, if you don't - until anyone tells you
otherwise, you should have no cause for concern.
It is a bit like car recalls. They happen all the time but it doesn't stop you getting into your car in case there's a problem with say, the brakes.
