I was looking for a notebook with 17.3-inch, dual-core and without operating system. The Satellite L670D-15U I found it. Since I have already Win7 64bit OEM, a preinstalled Windows was superfluous. The Toshiba had the factory only 2GB of RAM, so I've just ordered with order 4GB of memory. It is installed Samsung memory PC85000 DDR3 CL7 (1066). The NB and memory were supplied, so that I could install the memory in front of Intriebnahme. The NB now has a total of 6 GB of memory - enough for many applications. The required driver could be downloaded without any problems from the clear side Toshiba. Win7 drivers, additional programs to be installed without any major problems. When the driver of the WLAN module you need to know which module is installed. Here Toshiba offers 4 different manufacturers on the driver side. For me it was the Realtek Wireless N module. The processing of the NB is solid and the surface has a carbon look. Very good I think the small button above the touchpad. Thus, the touchpad and the two "mouse buttons" are turned off / and switched on again. Fast and direct switchable. Class Toshiba. Many other manufacturers this is solved cumbersome than second key assignment. The AMD Dual Core is sufficiently fast and blends well with the GraKa. The Toshiba hard drive is fast ausreichtend with 5400 U / pM. The fan is unobtrusive and not annoying - not even under load. Sound is ok - what you can expect from internals speakers so. The keys are kept flat and pleasant to touch. The screen dissolves very well and the LED backlight is very good. Conclusion: For the money - buy !!! But upgrading the RAM is a must - unless you use a non-Windows operating system and comes with 2GB of. Here again a compliment to Amazon! Ordered / delivered one day later. There's nothing faster !! Great.
