Battery & Power Supply

Repair or Replace your Battery / Power Supply

Apple uses Lithium-Polymer batteries in all their battery-powered products. Whether it’s an iPod shuffle or a MacBook Pro, the battery technology is the same. Not only does that mean Apple only has to source and use one type of battery, but it means our usage and ways to charge work across all of their product lines. We’ll be focusing on the Mac and how you can best maintain and charge your portable’s battery.

We have diagnostic tools to quickly test the battery. Batteries nowadays are extremely smart. They contain all kinds of information such as their charge times, usage and more. The cycle count and all these times are stored within the battery’s own circuitry. When the battery is tested, the Experts at our Apple Center will get an notification as to whether the battery is faulty or not.

Clues to the causes of Mac startup problems can be found by analyzing when in the boot process the system fails. Problems may be related to the power supply, battery, hard drive, logic board, OS corruption or an issue with a user account. Macs are reliable machines, but like many of us they get cranky from time to time.

If your Mac won’t power on at all, likely suspects are a failed power supply, a bad logic board, a blown fuse (on desktops), a dead battery or a bad AC adapter (on portables). Failed power supplies are sometimes accompanied by a popping sound. That’s usually a capacitor which has given up the ghost and burst open. iMac G5 systems frequently suffer from bad power supplies. Supplies can fail fully or partially – they may give some power to the fans and such but still not work properly. Fortunately a power supply or AC adapter is relatively inexpensive to replace.

Laptops have an additional power supply in the battery. A dead or defective battery can prevent your MacBook or PowerBook from booting, or the battery may keep your system running after a crash, unable to reboot. For laptops that have removable batteries (a dying Apple breed) remove the battery and unplug the computer when troubleshooting.

Macs also have another battery, called the PRAM (or NV-RAM) battery, that saves things like network settings, choice of startup drive, etc. If the date and time reset each time you unplug the Mac you need a new PRAM battery. A dead or dying PRAM battery can prevent a Mac from booting or cause erratic behavior. Sometimes plugging in the computer and letting it sit for 30-60 minutes recharges the battery enough to permit booting.
