Ye I observed that while opening more than 2 tabs in chrome browsers the system hangs and when you switch back to either of tabs the screen will appear white for first 2 sec then the whole thing will load up. keyboard is perfect but while pressing backspace most of the time. I don’t know whether the slow and lagging is due to 2 GB RAM or may be it can perform well after upgrading the RAM.While playing videos when you seek the video display will be scattered and after 1 or 2 sec it will come to normal. I am feeling like a fool. very bad laptop. Don’t wist time
