Not all notebooks can be opened 180 degrees.
The TravelMate's colors are businesslike.
The case is made entirely out of plastic ...
... and the base is much more stable than the lid.
Overall, the P449 is fairly similar to the more expensive P648 ...
... from the positioning of the Acer logo ...
... to the exact same hinge design.
The bottom cover is equipped with two maintenance flaps.

Tempi di risposta del Display

I tempi di risposta del display mostrano quanto sia veloce lo schermo a cambaire da un colore all'altro. Tempi di risposta lenti poccono creare sovrapposizioni negloi oggetti in movimento. Specialmente i giocatori patiti del 3D dovrebbero usare uno schermo con rempi di risposta bassi.
       Tempi di risposta dal Nero al Bianco
28 ms ... rise ↗ and fall ↘ combined↗ 16 ms Incremento
↘ 12 ms Calo
Lo schermo mostra tempi di risposta relativamente lenti nei nostri tests e potrebbe essere troppo lento per i gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
39 ms ... rise ↗ and fall ↘ combined↗ 22 ms Incremento
↘ 17 ms Calo
Lo schermo mostra tempi di risposta lenti nei nostri tests e sarà insoddisfacente per i gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 25000 Hz70 % brightness setting

The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 70 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

I portatili economici business come questo sono a volte definiti come pane quotidiano nel mercato dei portatili dai produttori, non è una cosa particolarmente eccitante ma è un punto di forza delle vendite. Distinguersi dalla concorrenza è abbastanza difficile, e la maggior parte dei dispositivi si perde nella massa. Questo vale anche per il TravelMate P449: portatile business solido ma nulla di più.

In particolare ci piace il touchpad molto buono del P449. Un touchpad mediocre o scarso può rovinare tutto, e apprezziamo il fatto che il produttore abbia prestato sempre più attenzione a questo aspetto negli ultimi anni. Considerando che alcuni produttori, come HP, ancora montano sui loro portatili business degli scarsi pannelli TN, il pannello IPS del P449 è un plus. Abbiamo apprezzato anche le basse temperature di superficie del P449 ed il veloce PCIe-SSD che manca su tutti i concorrenti.

Non è il massimo, ma nemmeno roba da poco. Il TravelMate P449 è abbastanza piatto ma buono nella costruzione.

Purtroppo quello che si risparmia da un lato lo si paga dall'altro, e quindi a fronte di un veloce PCIe-SSD il P449 monta un SD card reader molto lento. Inoltre non ci è piaciuto il design della tastiera, ed il fatto che il P449 ha uno slot per drive da 2.5" ma mancano i connettori e la ventola resta un mistero. Considerando le temperature basse davvero non capiamo perché la ventola non è spenta completamente quando il dispositivo è in idle o sotto carico leggero. Come tutti i dispositivi di questo segmento di mercato, la copertura del colore del display è abbastanza scarsa. L'autonomia è limitata, e tutti gli altri dispositivi durano nettamente di più nei nostri tests.

Considerando tutti gli aspetti il TravelMate P449 può essere un dispositivo buono a patto che ci si abitui alla tastiera. Nessuno dei suoi concorrenti è perfetto ma sicuramente ci sono dei vantaggi indubbi, come la batteria removibile o la GPU dedicata.

Nota: si tratta di una recensione breve, con alcune sezioni non tradotte, per la versione integrale in inglese guardate qui.
