Another common problem is loose internal computer connections, which commonly occur after transporting the computer. Keeping the possible consequences to your warranty in mind, as well as all safety precautions, you may wish to refasten the internal connectors, with care. Be careful though: disconnect the power cable first, and wait for the high voltage to drop. Ground yourself to the computer with an anti-static strap, or by touching the metal components of the case. This can prevent visits to the repair man (or the hospital).

Viruses

Regrettably, there are some malicious people who program and distribute viruses, solely to cause damage. Check your drives regularly for viruses, especially if you download data from the Internet. Not all virus programs are able to detect macro viruses, and others which are, as yet unknown, to virus protection software developers.

Re-installing or Updating the Operating System

It is possible that as a result of a crash, or installation error, the operating system will become unusable. If this happens, re-install the operating system from your system CD-ROM.

To do so, restart your computer using the Mac OS X Installation CD (insert the CD and select it as the start volume in the corresponding control panel; or on newer Macs, simply press Command during the restart) and re-install the operating system.

Sometimes, the problems simply come down to the operating system. You can usually find updates for your operating system online, where they can be downloaded free of charge.

Formatting the Hard Disk

Formatting the hard disk is the absolute last resort you should attempt, before sending the computer for repair. This will erase all files on your hard disk, and any garbage data that may be causing your problems.

The formatting process will erase all files, so make backups of all files and programs first—and verify these backups—to ensure that they have been successful. Be sure to run virus checking software on all backups, to avoid re-infecting your newly formatted drive.

To format the internal hard drive, you will need to start your computer from another drive, either from the CD-ROM, a flash drive, or an external hard disk. To completely rule out a virus problem, you should reformat all hard drives in the same session—a CD-ROM cannot be infected with a virus (unless it was infected to begin with).

Important: Please keep in mind that invisible software authorizations cannot be copied—please de-authorize such applications from your hard drive before erasing it!

8 specifications

The Apple iPhone 8, introduced in September 2017, marked a significant evolution in the company's smartphone lineup, bridging the design elements of the past with cutting-edge technology. The iPhone 8 brought several notable features and advancements that enhanced user experience and performance.

One of the most striking design elements of the iPhone 8 is its glass back, a departure from the aluminum unibody design of its predecessors. This transition not only provided a fresh aesthetic appeal but also enabled wireless charging, allowing users to power their devices conveniently without the need for cables. The iPhone 8 supports Qi wireless charging standards, making it compatible with a wide array of wireless charging pads.

Under the hood, the iPhone 8 is powered by Apple’s A11 Bionic chip, which features a six-core CPU. This powerful processor significantly improved the iPhone's speed and efficiency when compared to previous models. The A11 Bionic was designed for machine learning applications and includes a dedicated neural engine, allowing for better performance in tasks such as image recognition and augmented reality experiences.

The display of the iPhone 8 is a 4.7-inch Retina HD display, boasting True Tone technology, which adjusts the screen's white balance based on the ambient light. This feature not only enhances color accuracy but also improves comfort for users by reducing eye strain in various lighting conditions. With a resolution of 1334 x 750 pixels, the display delivers sharp and vibrant visuals.

Camera capabilities on the iPhone 8 also received significant upgrades. The rear 12-megapixel camera features optical image stabilization, providing clearer photos and smoother video recording, even in low light conditions. The introduction of new color filters and a larger sensor allowed for improved photo quality. The front-facing 7-megapixel camera supports 1080p HD video recording and features advanced portrait mode, offering users new ways to create professional-quality selfies.

Another important aspect of the iPhone 8 is its robust security features. The device continued to use Touch ID for biometric authentication, ensuring that users' data remained secure. Additionally, the iPhone 8 was water and dust resistant, rated IP67, which added an extra layer of durability.

In summary, the Apple iPhone 8 successfully combined innovative technology with timeless design. Its wireless charging, powerful A11 Bionic chip, enhanced camera features, and sturdy build quality made it a compelling choice for consumers looking to experience the best of Apple’s engineering prowess.
