This can indicate a corrupt installation of Mac OS X or a failed (or failing) hard drive.Ī pass through the excellent DiskWarrior utility is highly recommended for any disk-related startup problems. The flashing question mark or a circle/slash means your Mac can’t find a valid startup disk. Leaving a failing drive struggling too long can cause further damageįlashing question mark with folder, or circle/slash Sometimes switching on/off a few times can help, but don’t push things under these circumstances. This can indicate a failed or failing hard drive. Sometimes a Mac will power on but the hard drive will squeal, whine very loudly or make ticking sounds. If your Mac doesn’t make any noise at all when switching it on, or if you hear the fans running but nothing else, you may again have a power supply or logic board failure. Listening to your computer may seem a bit metaphysical, but can provide helpful clues to startup problems. Sometimes plugging in the computer and letting it sit for 30-60 minutes recharges the battery enough to permit booting. A dead or dying PRAM battery can prevent a Mac from booting or cause erratic behavior. If the date and time reset each time you unplug the Mac you need a new PRAM battery. “There is a charging problem” and “Charging Paused” would be good starting points.Macs also have another battery, called the PRAM (or NV-RAM) battery, that saves things like network settings, choice of startup drive, etc. I hope Apple decides on some different phrases for two of those statuses. Still, there’s a really easy fix for this. Given the prominence that the Battery Health software has received from Apple, I’m surprised that this slipped through the attention to detail net. Three different scenarios, all of which offer important feedback to the user, and one single text string. In essence you can get the message “not charging” while you are charging, “not charging” while you are not charging, and “not charging” when you have an issue with the charging hardware. "You might also see “Not Charging" when your Mac isn't getting enough power to charge the battery, such as when it's not using the correct power adapter and cable, or it's plugged into a power source that isn't delivering enough power." Subsequent paragraphs in the support document make it clear why there is confusion around charging under the new system: The failure here is not a failure of the battery, or the charging circuitry, it is a failing of Apple’s user interface.
