I am using acer aspire 5755g from 1 year. It has core i5 2nd generation processor. Though it has core i5 it runs as turtle. Sometimes you’ll think that even it has processor or not? And it also has 4gb ram but its none of use. I have installed some educational softwares. After installing them laptop has become a junk. Keypad of laptop is also not working properly. Only few keys are working and few not. There is only one thing I liked in it and its a fast charging. It gets fully charged only in half to one hour. Though it charges in an hour but its discharging speed is as same as fast charging. Battery backup is worst. It also gets heavily heated while using and charging. Its heavy in weight.
