Reassembly Notes

Important

After replacing the display assembly or motherboard, you must use the Service Utilities floppy disk to reprogram the EEPROM on the motherboard for the new display.

1.Download the notebook Series service package from the Partnership Web site (see page vi), and create a Service Utilities floppy disk as described in the package’s Readme file.

2.Plug in an AC adapter.

3.Insert the Service Utilities floppy disk in the floppy drive. If the unit has no internal floppy drive, connect a USB floppy drive.

4.Turn on the notebook.

5.When you see the HP logo, press ESC to display the boot menu, then boot from the floppy drive.

6.Select the option to update the display/LCD identification stored on the motherboard.

If you are replacing the CPU module, you must also replace the thermal pad on the heat sink (see page 2-28).

Wireless Models Only

Before installing the motherboard, make sure the round coaxial cables from the antenna PCAs are held in place by the clips in the bottom case.

Make sure there is sufficient length to the front antenna PCA cables so they can easily be connected to the mini-PCI card.

Reassembly Procedure

Caution

Be extremely careful when replacing the motherboard. The motherboard has EMI springs attached to it that can bend very easily. Bending any EMI spring could cause a motherboard short.

Note: Reprogramming the BIOS IC

A new BIOS IC contains only enough basic programming to enable the notebook to boot. After installing a new motherboard, you must reprogram the BIOS IC, preferably with the latest BIOS—see page 2-35.

2100, 1100 specifications

The HP 1100 and 1100A are pivotal laser printers developed by Hewlett-Packard in the early 1990s, marking significant advancements in printing technology of their time. Since their introduction, these models have garnered a reputation for reliability and efficiency, making them a staple in many offices.

One of the standout features of the HP 1100 series is its fast printing speed. The printers can produce up to 12 pages per minute, which was an impressive feat at the time of their release. This speed significantly reduced waiting times, allowing users to handle large-volume printing jobs with ease. Furthermore, the printers support a variety of media types, including letterhead, envelopes, and labels, enhancing versatility in print applications.

The HP 1100 and 1100A utilize laser technology, which ensures sharp and high-quality prints. The printers have a native resolution of 600 x 600 dots per inch (DPI), enabling crisp text and detailed graphics. This high-resolution output made the models particularly favored for producing professional documents and presentations.

Another key characteristic is the generous memory capacity. The HP 1100 typically comes with 2 MB of standard RAM, which is expandable, allowing for improved performance in handling complex print jobs. Users can adjust the memory according to their requirements, resulting in better efficiency, particularly in environments that demand high-volume printing.

The HP 1100 series also showcases a straightforward and user-friendly operation. The built-in control panel simplifies the printing process, allowing users to manage jobs intuitively. Additionally, with the inclusion of parallel and later USB connectivity options, integration with various computer systems was seamless, ensuring compatibility with existing office infrastructure.

Energy efficiency is another aspect worth noting, as the printers are designed to consume minimal power when idle, aligning with the growing demand for eco-friendly solutions.

Overall, the HP 1100 and 1100A stand out for their robust construction, high-speed performance, exceptional print quality, and user-friendly features, making them a trusted choice for small to medium-sized businesses in need of dependable printing solutions. Their impact on the printing landscape during the 1990s continues to be felt today, as they paved the way for subsequent generations of laser printers.
