To verify a symptom, do the following:

1.Turn off the computer.

2.Remove the battery pack.

3.Connect the ac adapter.

4.Check that power is supplied when you turn on the computer.

5.Turn off the computer.

6.Disconnect the ac adapter and install the charged battery pack.

7.Check that the battery pack supplies power when you turn on the computer.

If you suspect a power problem, see the appropriate one of the following power supply checkouts:

v“Checking the AC adapter”

v“Checking operational charging” on page 30

v“Checking the battery pack” on page 30

v“Checking the backup battery” on page 31

Checking the AC adapter

You are here because the computer fails only when the AC adapter is used.

vIf the power problem occurs only when the ThinkPad Essential Port Replicator is used, replace the port replicator.

vIf the power-on indicator does not turn on, check the power cord of the AC adapter for correct continuity and installation.

vIf the computer does not charge during operation, go to “Checking operational charging” on page 30

To check the AC adapter, do the following:

1.Unplug the AC adapter cable from the computer.

2.Measure the output voltage at the plug of the AC adapter cable. See the following figure:

Note: Output voltage of pin no.2 of the AC adapter may different from the one you are servicing.

3.If the voltage is not correct, replace the AC adapter.

4.If the voltage is acceptable, do the following: v Replace the system board.

vIf the problem persists, go to “ThinkPad SL400 and SL500” on page 49.

Note: Noise from the AC adapter does not always indicate a defect.

SL500 specifications

The IBM SL500 is a notable entry in the realm of high-capacity tape libraries, designed for organizations that require efficient data backup, archiving, and management solutions. It stands out due to its robust feature set, innovative technologies, and the capability to evolve with an organization's growing data needs.

One of the principal features of the IBM SL500 is its modular architecture, allowing businesses to start with a basic configuration and expand as their requirements grow. This scalability is crucial in accommodating increasing data volumes without requiring a complete system overhaul. The library supports a variety of tape formats, including the IBM LTO (Linear Tape-Open) technology, known for its high capacity and reliability.

The SL500 also integrates advanced features like a user-friendly graphical interface for monitoring and managing tape operations. This interface simplifies administrative tasks and provides real-time insights into the system's performance, allowing IT professionals to manage data more efficiently. Additionally, the SL500 comes equipped with automated handling capabilities, such as robotic arms that minimize manual intervention, thus reducing the risk of human error and improving operational efficiency.

In terms of scalability, the SL500 supports multiple drive configurations and slots for cartridges, which can house thousands of tape cartridges, enabling organizations to tailor the system to their unique data storage needs. It can include up to 10 tape drives and house more than 7,000 cartridges, offering a massive storage capacity that is both reliable and secure.

The library's robust security features further enhance its appeal. It includes data encryption capabilities to protect sensitive information stored on tapes, ensuring compliance with various regulatory standards. Moreover, its integration capabilities with IBM Spectrum Protect and other data protection software allow organizations to streamline their backup and recovery processes.

Another significant aspect of the SL500 is its energy-efficient design. IBM has incorporated energy-saving features in the library, reducing operational costs and environmental impact. This forward-thinking approach reflects a growing need within data management solutions to balance performance with sustainability.

In summary, the IBM SL500 is an advanced tape library system that combines scalability, automation, security, and energy efficiency. With its various features and capabilities, it is an appealing choice for businesses seeking to enhance their data management strategies while accommodating future growth.
