HP 840 Laptop keyboard EliteBook 840’s backlit keyboard is tight; it sharply sinks into the chassis, and the keys feel substantial and clicky while you’re typing. The backlighting has only two settings, which is disappointing for a laptop of this price. For business users, however, HP included three useful keys to present, answer and hang up calls

HP 840 Laptop keyboard keys have somewhat short travel (1.4 millimeters) but require strong actuation force (77 grams). We usually look for travel between 1.5 and 2 mm and actuation force above 60 grams. The keyboard is incredibly comfortable, allowing me to sail past my 60-words-per-minute average with 68 wpm on the 10fastfingers typing test.
