When my Lenovo S205 had problems with the SATA controller, I came back and sent for this Lenovo IdeaPad N581 ordered me with an Intel Core i3. The great thing about this notebook is the service flap! It is super fast to the hard disk and memory. Only loosen 2 screws and you've got access. Excellent !!! The standard hard drive out (320GB) and a Samsung SSD 840 120GB pure. Since I had an image (Win8 Pro) of my Lenovo S205, I have the functionality of Acronis Universal Restore used and played the image of Lenovo S205 on the Lenovo N581. Driver corpses away and provides the latest hardware drivers and already runs the part as hell ^^! : D The Lenovo N581 has a SATA 3 controller and thus the SSD is fully maxed out! Two USB 2.0 ports and two USB 3.0 ports are available also a HDMI port! The display is quite bright and not pixelated and games such as World of Tanks run quite fluid! The processing itself is absolutely fine for the price and who should invest more here rumnörgelt. The battery lasts a good 4 hours at normal use and in general there is running very round! A blue screen I have not had so far! With the SSD it goes sau quickly up and takes about 15 seconds to the desktop there is! The touchpad is multi-touch capable and can be operated well. Primary is always a mouse but uses a pinch it would go well with the touchpad. I have the notebook now since about one week operation and was able to establish not a single deficiency! Said round, I'm pretty satisfied!
