Apple has faced temporary problems sourcing spare parts for MacBooks affected by intermittent random shutdowns. Some users have complained that their MacBooks have developed a penchant for this problem. In essence, the fault is one in which some – but not all – MacBooks will simply close down during normal use.

This fault appears to affect a small but substantial minority of MacBooks, and usually manifests itself after a period of normal use. The fault is intermittent and hard to pin down. Apple’s technical support department has told some users that re-seating the memory modules may mitigate it in some cases.
