In 2008 the first series of VGN-Z was introduced. The second series was introduced in December 2009 as a part of the Intel
Centrino 2 launch. They fall into the
ultraportable category, with a 13.1-inch screen and 1.47 kg weight (3.4 lb) (dependent on configuration). They were configured with Intel Core 2 Duo CPUs. Compared with the SZ series, the Z is slightly lighter (200 grams), with a slightly smaller (13.1" vs. 13.3") screen, which was switched from 16:10 to 16:9 widescreen aspect ratio. In comparison to the SZ, which was available only in 1280×800 resolution, the Z series come with a choice (model-dependent) of screens which were 1366×768 and 1600×900 TN panels. As with the SZ, the Z has hybrid graphics, featuring an NVIDIA GeForce 9300M GS as well as Mobile Intel 4 Series Express 4500MHD chipsets. The user can switch between the Nvidia (for better graphics performance) and Intel (for longer battery life) via a 2 way switch above the keyboard. Newer options with the Z series are an integrated
Blu-ray Disc drive, built-in
HSDPA support and the use of an
SSD (including RAID configuration, for better performance) instead of a hard drive for storage. Other features include a 0.3 megapixel webcam, Bluetooth, SD and
Memory Stick reader, FireWire 400 port, fingerprint sensor and
Trusted Platform Module support. As with the SZ series, the Z is equipped with standard, rather than ultra-low voltage (which are slower, but produce less heat and provide better battery life) processors. The CPUs are generally Core 2 Duo P- (mid-voltage) CPUs, but also T- (standard voltage) CPUs. Additionally, the CPU uses a
Socket P socket rather than being soldered to the motherboard.
Intel VT-x support was intentionally disabled in the laptop's BIOS, resulting in the use of hacked BIOSes by some users. Sony claimed VT had been disabled for security reasons, but eventually enabled the feature in November 2009. Sony originally shipped Windows Vista with the computer, however they offer options to downgrade to Windows XP or upgrade to Windows 7. == VPC-Z Update (2010) ==
