HP OmniBook 900
The OmniBook 900 is a Pentium II/III-based laptop that was released in January 1999. An updated revision with ATI graphics and some other changes known as the OmniBook 900B was released a little while later.
You can quickly identify if a laptop is the B variant based on the OmniBook name plate on the lid. If it is gray, it is an OmniBook 900. If it is silver, than it is an OmniBook 900B.

Common Faults & Maintenance
Brittle Plastics
The OmniBook 900's plastics are very brittle due to age. Most units I see on eBay have cracks forming near the display hinges, so it's likely that epoxy will be required to keep one intact.
