HP ProBook 6440b Notebook PC Product Specifications

Product description

HP ProBook 6440b Notebook PC

Product features

Mobile Intel HM57 Express Chipset
Intel Quad-Core Processor (models with discrete graphics only):
  • Intel Core i7-720QM Processor (1.60-GHz, 6MB L3 cache) Up to 2.8 GHz with Intel Turbo Boost Technology
Intel Dual-Core Processors:
  • Intel Core i7-620M Processor (2.66-GHz, 4MB L3 cache) Up to 3.33 GHz with Intel Turbo Boost Technology
  • Intel Core i5-540M Processor (2.53-GHz, 3MB L3 cache) Up to 3.06 GHz with Intel Turbo Boost Technology
  • Intel Core i5-520M Processor (2.4-GHz, 3MB L3 cache) Up to 2.93 GHz with Intel Turbo Boost Technology
Intel's numbering is not a measurement of higher performance. Processor speed denotes maximum performance mode; processor will run at lower speeds in battery optimization mode.
Standard: DDR3 PC3-10600 SDRAM (1333 MHz)1 Two SODIMM slots supporting dual-channel memory 1024MB, 2048MB, 3072MB, or 4096MB
Maximum : Upgradeable to 8192MB with 4096MB SODIMMs in slots 1 and 2
Dual-channel: Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots
Due to the non-industry standard nature of some third-party memory modules, we recommend HP branded memory to ensure compatibility. If you mix memory speeds, the system will perform at the lower memory speed. Full availability of 4GB or more of memory requires a Windows 64-bit operating system or Linux. With Windows 32-bit operating systems, the amount of usable memory is dependent upon your configuration, so that above 3GB all memory may not be available due to system resource requirements.
Models with discrete graphics:
  • ATI Mobility Radeon HD 4550 with 512MB dedicated video memory
  • Microsoft DirectX 10.1 (Shader Model 4.1) and OpenGL 2.1 capable
Models with integrated graphics:
  • Intel Graphics Media Accelerator HD
  • Microsoft DirectX 10 (Shader Model 4.0) and OpenGL 2.0 capable

External: Up to 32-bit per pixel color depth
DisplayPort supports resolutions up to 2560 x 1600, 30-bit color depth at 60 Hz, and full HD (1920 x 1080) monitors, 24-bit color depth at 120 Hz
VGA port supports resolutions up to 2048 x 1536 at 75 Hz, and lower resolutions at up to 100 Hz
DVI-D (single link) video signal available through DVI port in optional HP Docking Station (sold separately) supports resolutions up to 1600 x 1200 at both full and reduced blanking, and 1920 x 1200 at reduced blanking
Resolutions are dependent upon monitor capability, and resolution and color depth settings.
The HP spill-resistant keyboard is designed using a thin layer of Mylar film under the keyboard and a drain system that funnels fluid through a hole in the bottom of the notebook. This minimizes the risk of damage to sensitive components underneath. The 101/102-key compatible keyboard features an industry standard, full-pitch key layout with desktop keyboard features, such as the isolated inverted-T cursor control keys, editing keys, both left and right control and alt keys, and 12 function keys. U.S. and International key layouts are available. Includes an integrated numeric keypad, hotkeys for instant access to power conservation, brightness, and other features. It has 19.05 x 19.05 mm key pitch (center-to-center spacing) and 2.5 mm stroke.

Internal Storage Device
Hard drives 160/250/320/500GB 7200 rpm SMART SATA II
These hard drives are customer removable and will withstand multiple insertion/removal cycles. Up to 15GB is reserved for the system recovery software.
HP 3D DriveGuard (Windows only) The hard drive is mounted directly to the notebook frame, reducing the transmission of shock to the hard drive. Uses three-axis digital motion detection with intelligent sensitivity to help protect the hard drive during normal use from shock and vibration. The digital accelerometer temporarily halts all data transfer and parks the hard drive when abrupt motion is detected.
