I'm currently using a Dell Inspiron 15r with 15'6HD i5 3210m @2.5ghz 4gbram AMD Radeon 7700M series W8.1(free update) 1TB hard disk at Rm2300
Bought it near 3 years already, my experience with this laptop is very bad. It keeps on lag and hang when normal use like open programs and stuff, and sometime crash. Would really look to have a good laptop without lags or hangs at least on running normal stuff. I bought it because the specs and price are good.

Looking forward to sifu's reply
