Breve aggiornamento Portatile Lenovo B50-45

Sotto la media. Lenovo ha deciso di usare la nuova APU Beema AMD sul suo B50-45. Solo 390 Euro (~$494) per un semplice portatile da ufficio da 15.6". Tuttavia, il computer rispecchia a pieno il suo costo.

With the B50-45, Lenovo has a simple 15.6-inch notebook in its line-up, which performs well in office and Internet use as well as video playback. Its CPU and GPU performance are significantly higher than the already reviewed Lenovo B50-30's. Intel's Bay Trail is not a competitor to the AMD APU. In addition, we liked the low system noise and the low temperature increase of the B50-45. Thanks to the big maintenance hatch, the hard drive can be easily replaced. The matte display surprises with a very decent contrast. However, the springy keyboard is a point of critique. Other cheap notebooks come with significantly better keyboards. In addition, we did not like that the warranty period is only for 12 months. The poor battery life in the WLAN test has to be mentioned, too. Nowadays, we expect a result of above 4 hours.  With a battery life of 6:31 h, the Extensa 2510 is exemplary in this aspect.
