Common Building Block (CBB) was a set of technical standards for laptop components introduced by Intel in 2005, and adopted by some manufacturers.
Creation
In 2004, the Common Building Block program promoted the use of industry-accepted mechanical and electrical specifications for three notebook components: 14.1-inch, 15-inch, and 15.4-inch liquid crystal displays (LCDs); 9.5mm and 12.7mm optical disc drives (ODDs); and 2.5-inch hard disk drives (HDDs). The program consisted of:
- A Web site to provide a centralized repository of information about the program, participants, and platform and ingredient specifications
- A continually updated list of CBB-compliant ingredients (submitted by suppliers)
- A testing and verification service for candidate products
The defunct repository site mobileformfactors.org was established to standardize components, and included:
- Hard disk drives
- Optical disc drives
- Liquid crystal display panels
- Battery packs
- AC/DC power adapters
- Keyboards
- Customizable notebook panels
