Important: To avoid electrostatic discharge, always ground yourself by touching the port access covers before you touch any parts or install any components inside the computer. To avoid static electricity building back up in your body, do not walk around the room until you have completed the installation and closed the computer.

7.Unplug the power cord.

Warning: The power supply in your computer is a high-voltage component and should not be opened for any reason, even when the computer is off. If the power supply needs service, contact your Apple reseller or Apple Authorized Service Provider.

8.Lift the latch on the right side access panel.

9.Gently lower the access panel until it lies flat. To avoid scratching the case, lower the panel onto a soft, clean cloth.

Warning: If you see any lights glowing on the main logic board, the computer has not been shut down. Close the side access panel and shut down the computer before proceeding.

Power Mac G4 Battery specifications

The Apple Power Mac G4, introduced in 1999, marked a significant milestone in Apple's evolution of personal computing. Although primarily a desktop workstation focused on high performance for creative professionals, it has features worthy of mention, particularly regarding its power management and battery configurations in specific models.

Unlike typical laptops, the Power Mac G4 did not utilize a battery in the traditional sense. It was a desktop computer designed to operate primarily from a wall outlet. However, certain models such as the Power Mac G4 Cube, which shared many internal components, had unique aspects related to power management and energy efficiency that can be discussed in the context of battery-like characteristics.

One notable feature of the Power Mac G4 series is the implementation of Apple's innovative energy-saving technologies. These technologies helped optimize the power consumption of the devices, a forward-thinking approach for the time. The system's architecture allowed for adjustable clock speeds, enabling users to scale performance according to their needs while simultaneously reducing energy consumption.

With a maximum RAM capacity of up to 2 GB and processor speeds ranging from 400 MHz to 1.25 GHz, the Power Mac G4 offered impressive performance capabilities that suited a wide array of tasks, including graphic design, video editing, and music production. The use of the Motorola 7400 (G4) microprocessor allowed the system to handle complex computations efficiently, leveraging features such as Altivec technology for accelerated multimedia processing.

The G4 also included ports for USB and FireWire, enhancing connectivity with external devices. This versatility allowed users to employ various peripherals, further extending the functionality of the workstation. Moreover, the option for dual processors in some models enabled users to tackle multi-threaded applications effectively.

In conclusion, while the Apple Power Mac G4 did not traditionally feature a battery, its energy-saving technologies and power management features represent essential considerations in its design. Its impressive architecture, performance capabilities, and connectivity options have made it a cherished piece of computing history, particularly among creative professionals and enthusiasts who appreciate its pioneering spirit.
