Centrino-Sonoma platform (2005)

Intel used Sonoma as the code-name for the second-generation Centrino platform, introduced in January 2005.
The Sonoma platform consists of:
an Intel Pentium M processor (code-named Dothan) with a 533 MT/s FSB, Socket 479 and
an Intel Mobile 915 Express series chipset (code-named Alviso with Intel's GMA 900), DDR2-533 and
the Intel PRO/Wireless 2200BG or 2915ABG mini-PCI Wi-Fi adapter (code-named Calexico2).
The Mobile 915 Express chipset, like its desktop version, supports many new features such as DDR2, PCI Express, Intel High Definition Audio, and SATA. Unfortunately, the introduction of PCI Express and faster Pentium M processors causes laptops built around the Sonoma platform to have a shorter battery-life than their Carmel counterparts; Sonoma laptops typically achieve between 3.5-4.6 hours of battery-life on a 53 W-h battery.
