Contra
- Pantalla de bajo contraste y dependiente del ángulod e visión
- El portátil produce un pitido electrónico
El HP EliteBook 840 G2 es principalmente una actualización a Broadwell. HP no ha modificado nada aparte del cambio de procesador. El procesador Broadwell implica ciertas mejoras respecto al precursor. El EliteBook 840 G2 consume menos energía, tiene un menor ruido de funcionamiento y temperaturas ligeramente inferiores. Y dura más en nuestras pruebas de batería de uso realista. Para evitar toda duda: El EliteBook 840 G1 no puntuó mal en ninguna de las pruebas. Los modelos G1 y G2 son por lo demás idénticos. Ambos tienen dispositivos de entrada decentes, muy buenas opciones de mantenimiento y una carcasa delgada de gran calidad. Lo que es más, ambos modelos vienen preparados para SSD M.2 y el módem LTE/3G. El modelo G1 que probamos viene con el modem correspondiente. Por desgracia, HP no ha eliminado su punto débil más importante del EliteBook 840 G1, y lo mantiene en el EliteBook 840 G2: La pantalla. Las pantallas de ambos modelos tienen poco brillo y contraste. También tienen pantallas TN dependientes del ángulo de visión. HP pide 1500 Euros por el portátil; una brillante pantalla IPS de gran contraste debería estar en la configuración estándar a la vista de este precio.
