HP ProBook 4420s Specification

Keyboard
KeyboardKeyboard
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).

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.
