Hiii friends here I am going to describe about lenovo G580 This is not a good preforming device.i feel very disppointed due to this.it has very poor accesong it takes long time to open any file.it cant store atleast a small information in this memory.eventhough if we install any software .it ask automatic updates it self. Network isuess may occuar frequantly.when we are using this.it looks like nice towards appearence but performance wide it is too good that why I had to review on lenovo G580.it need os update frequently.so finally I decided to change this pc some times keyboard isuess may appear. Thank yoh
