This was, however, our selection criteria for the four best 15.6-inch laptops. Also, we have selected only notebooks that have 4GB RAM. Some notebooks in this price range have only 2GB RAM. When Lenovo B555, however, you have to install two of the 4 GB RAM still own. And the Acer Aspire one cannot even upgrade to 8 GB, the other is not an extension of memory possible. All four laptops have dual core processors, but a different kind of Lenovo G555 has an AMD Turion Dual-Core M520 with two times 2.3 GHz.
The other three have Intel processors, which are now purchased much more frequently. Acer has installed in the two models have an Intel Pentium (Dual Core) T4500 two times with 2.3 GHz. The other Lenovo laptop (Lenovo B550) has an Intel Core 2 Duo T6570 processor, which twice has 2.1 GHz. The Lenovo G555 has the largest hard disk on our four candidates - 500 GB, while the other three have all 320 GB hard drives. But this should be sufficient for most purposes. The 15.6-inch displays of discount Sony laptops all have a resolution of 1366 x 768 pixels (WXGA TFT). Lenovo, the two devices have a glossy display, which acts in the spaces usually a little more pleasant for both notebooks Acer has a matte screen. The anti-glare matte display is judged to be especially advantageous if you want to use the laptop often outdoors. The graphics cards of the laptops are also different. The Lenovo B550 and the Acer TravelMate loved both the Mobile Intel GMA 4500M graphics, the Acer Extensa an NVIDIA GeForce G105M and the Lenovo G555 has an ATI Mobility Radeon HD 4550 The latter two graphics cards may be better suited for games than Intel. For normal work on the laptop or for video, she should be sufficient but also. The Acer and Lenovo B550 have an LED-backlit (backlight), the other not both.
The two displays, the Acer HD-capable devices are not the Lenovo laptops. A double layer DVD burner, all four laptops, three USB slots, Ethernet and wireless LAN as well. Having a 5in1 card reading the Aspire and the Lenovo G555, the TravelMate has a 2in1 card reader. Of this moderately-equipped Aspire has the worst facilities in terms of the sound, he has only one speaker. The other devices all have audio systems with two speakers. An integrated microphone, and output for external audio devices, all four notebooks. In size and weight, the four candidates also differ little: Both Lenovo models weigh 2.7 kg, 2.6 kg and the TravelMate Extensa 2.5 kg.
The battery life distinguish itself: The Lenovo devices last a little longer by with 4 hours on the G555 model and 3, 5 hours, the B550. The TravelMate has his name in accordance with 3.1 hours, a little better than his colleague Extensa battery with 2.5 hours. Whom the mobility of a notebook is very important that was to decide among these models, so better for the Lenovo G555. This also has the most space on your hard drive, but the worst processor. It should therefore be the slowest of the four notebooks. Whom the speed is more important than battery life and hard disk space that will decide more for one of the other three models. At the speed have Lenovo and Acer Aspire B550 nose in front.
The TravelMate is lagging a bit behind in speed and even with the battery life (3.1 hours) moderate. The TravelMate has under these presented here is not the best or worst battery life or speed, but is always in the middle. Only the worst sound he has. But a 2in1 card reader and antireflection coating. The Lenovo B550 is pretty fast for its price class and has 3.5 hours, even a bad battery life. His shortcoming is the lack of card reader. But its battery lasts but an hour longer than the battery of the Aspire. The Acer Aspire of wins for those who want a fast laptop that does not necessarily run with a long battery needs (2.5 hours, he can), but absolutely should have a 5in1 card reader and antireflection coating.
