Although extremely rare, there is always the possibility of an error occuring during the flashing procedure. I think flashing should only be done if needed. I would check to see what the changes were in the newer BIOS beforehand, and then evaluate for my situation before deciding. If none of the updates are needed then why risk it? In the event of an error there is the chance of having to send the notebook in for service. If you do flash make sure you have ample battery and that you are also plugged in.
