Users owning a 15- or 17-inch MacBook Pro that is either the "Mid-2010" or the "Early 2011" models will soon see an SMC firmware update for their machines that will update the firmware to version 1.7. The upgrade addresses "a rare issue on some Apple notebooks where a battery that has accumulated more than 1,000 charge cycles may unexpectedly shut down or stop functioning," according to the company. Apple rates the batteries as being good for 1,000 or more cycles.
