HP ProBook 4320s/4420s Notebook PC

Product features

Feature
Description
Chipset
Mobile Intel HM57 Express Chipset
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 Core i5-430M Processor (2.26-GHz, 3MB L3 cache)* Up to 2.53 GHz with Intel Turbo Boost Technology
  • Intel Core i3-350M Processor (2.26-GHz, 3MB L3 cache)
  • Intel Core i3-330M Processor (2.13-GHz, 3MB L3 cache)
note:
Processor speed denotes maximum performance mode; processors will run at lower speeds in battery optimization mode.
* Intel's numbering is not a measurement of higher performance.
Memory
Standard: DDR3 PC3-10600 SDRAM (1333 MHz)* Two SODIMM slots supporting dual-channel memory 1024MB, 2048MB, 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
note:
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.
note:
* Memory speed is processor dependent.

  • Intel HD Graphics
Discrete graphics:
  • ATI Mobility Radeon HD 4350 graphics controller with 512 MB dedicated video memory

note:
Resolutions are dependent upon monitor capability, and resolution and color depth settings.
Keyboard
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 a 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. US and International key layouts are available. Other features include hotkeys for instant access to power conservation and brightness, and 19.05 x 19.05 mm key pitch (center-to-center spacing).
