[QUOTE="westom, post: 1417674, member: 138367"] Read the specification numbers for a UPS. Protection is typically smaller than what a $7 protector from Wal-Mart claims to do. Most recommend the UPS for subjective reasons. Subjective reasoning can even prove the moon is made of cheese. Only relevant facts are spec numbers. The UPS claims near zero protection. Then advertising (subjective claims) can promote that into 100% protection. It is why scams are so easily promoted. The Mac has numerous internal protections. One is a safety lockout feature. If tripped, the lockout is cleared by disconnecting its power cord from AC mains. That safety lockup feature would explain no Mac power on and why a Mac worked again later. [/QUOTE]
