Cleaning Your Computer

Dell™ OptiPlex™ GX620

User's Guide

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

Computer, Keyboard, and Monitor

CAUTION: Before you clean your computer, disconnect the computer from the electrical outlet. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.

•Use a vacuum cleaner with a brush attachment to gently remove dust from the slots and holes on your computer and from between the keys on the keyboard.

NOTICE: Do not wipe the display screen with any soap or alcohol solution. Doing so may damage the antiglare coating.

•To clean your monitor screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the monitor's antistatic coating.

•Wipe the keyboard, computer, and plastic part of the monitor with a soft cleaning cloth moistened with a solution of three parts water and one part dish washing detergent.

Do not soak the cloth or let water drip inside your computer or keyboard.

Mouse

If your screen cursor skips or moves abnormally, clean the mouse. To clean a non-optical mouse:

1.Turn the retainer ring on the underside of your mouse counterclockwise, and then remove the ball.

2.Wipe the ball with a clean, lint-free cloth.

3.Blow carefully into the ball cage to dislodge dust and lint.

4.If the rollers inside the ball cage are dirty, clean the rollers with a cotton swab moistened lightly with isopropyl alcohol.

5.Re-center the rollers in their channels if they are misaligned. Ensure that lint from the swab is not left on the rollers.

6.Replace the ball and retainer ring, and turn the retainer ring clockwise until it clicks into place.

Floppy Drive

NOTICE: Do not attempt to clean drive heads with a swab. You might accidentally misalign the heads, which prevents the drive from operating.

Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated floppy disks to remove contaminants that accumulate during normal operation.

CDs and DVDs

NOTICE: Always use compressed air to clean the lens in the CD/DVD drive, and follow the instructions that come with the compressed air. Never touch the lens in the drive.

If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning the discs.

1. Hold the disc by its outer edge. You can also touch the inside edge of the center hole.

NOTICE: To prevent damaging the surface, do not wipe in a circular motion around the disc.

2. With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line from the center to the outer edge of the disc.

GX620, OptiPlex? GX620 specifications

The Dell OptiPlex GX620 is a desktop computer that was launched in the mid-2000s and quickly became popular in business environments. Despite its age, the OptiPlex GX620 remains notable for its build quality, upgradeability, and reliability, traits that have made Dell a respected name in the commercial PC market.

One of the key features of the GX620 is its compact form factor. The system was available in several configurations, including a small form factor (SFF) and a mini-tower, allowing it to fit comfortably in various workspace environments. This flexibility makes it an attractive option for businesses looking to save space while maintaining performance.

The GX620 was powered by Intel processors, specifically the Intel Pentium D and Intel Core Duo. These efficient processors provided ample power for productivity tasks, making the GX620 suitable for typical office applications such as word processing, spreadsheets, and web browsing. The system supported a maximum of 4GB of DDR2 RAM, which, while modest by today’s standards, was ample for the typical uses of its time.

In terms of storage, the GX620 offered several options, including traditional hard drives with variable capacities. This allowed users to select the right balance of performance and storage size according to their specific needs. Additionally, the system featured numerous connectivity options, including USB 2.0 ports, audio jacks, and an optional PCI Express slot for expanding capabilities with additional graphics or network cards.

The OptiPlex GX620 was equipped with Dell's management technology, which included remote management features that allowed IT departments to efficiently deploy and maintain multiple units across an organization. This was particularly advantageous for larger businesses that required centralized management tools to streamline operations.

Moreover, the GX620 was built with Dell's focus on sustainability and energy efficiency. The design considered environmental factors, and users appreciated its low power consumption relative to performance, aligning with corporate sustainability goals.

In conclusion, the Dell OptiPlex GX620 remains a notable example of robust desktop computing designed for business environments. With its compact design, reliable performance, and management features, it served well in various office settings despite being a product of an earlier era, showcasing Dell's commitment to quality and functionality.
