HP EliteBook 2540p Notebook PC

Product features

Mobile Intel QM57 Express Chipset
Intel Standard Voltage Processor, soldered:
  • 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 Low Voltage Processor, soldered:
  • Intel Core i7-640LM Processor (2.13-GHz, 4MB 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; processors will run at lower speeds in battery optimization mode.
Standard: DDR3 PC3-10600 SDRAM (1333 MHz)* Two SODIMM slots supporting dual-channel memory 1024MB, 2048MB and 4096MB SODIMMs.
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 channels.
* Memory bus runs at a maximum of 1066 MHz.
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.

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. Other features include an integrated numeric keypad, hotkeys for instant access to power conservation, brightness, and other features, 19 mm x 19 mm key pitch (center-to-center spacing), 2.0 mm stroke, and comfort-dished keycaps.
HP DuraKeys is a clear coating applied over the notebook keyboard that helps protect the finish and the printed characters on the keys. HP DuraFinish helps protect the finish on the keyboard deck, graphics, and icons from normal wear and tear.
HP Night Light shines directly on keyboard for low-light conditions.
