The notebook I'm fully satisfied (for that price). Work with it for about 1 month. In the detailed description on Amazon is indeed "Optical Drive: NO" (in the summary is DVD burner) also -As always, it comes with a DVD burner therefore. What is also good, because most are your problems have to install an operating system with no drive. RAM can be supposed to expand up to 16 GB (available in the instructions for use) - at Amazon is 8GB. Habs not tried it yet. I for around 30, - Windows 7 Pro - (OEM version) draufgespielt - going great. The driver that I downloaded from the Lenovo site for Win 7 running properly. To boot the computer needs approximately 30 seconds, then kanns go. From my old desktop I was used to worse. With 30 seconds to get on well. The notebook is conditioned game-compatible. The touchpad is lagging something. In the motion no signal comes through and at a standstill, it still needs a sec until you get back movement. The graphics card is middle class, but is good to play better than the Intel graphics. The DVD drive seems a bit rickety, but it works. I use it anyway ore rare. For the price the Notebookt brings everything with what I have wished for. The keyboard I find properly. The RAM is now rather small, with its 4GB, but at the price I can not complain about it.
Battery lasts in normal work (write texts, surf the Internet, archive images) 3-4 hours. USB ports there are only three, but at least 2 are 3.0er it! Webcam I can not say that I do not use. Display is quite ok. I like more mat, but I have no problems with this shiny. The resolution is normal in the price range. I am satisfied with the purchase!
