Firstly I want to say I am using this laptop since 4 years but still I dont face any difficulties like hanging problems & battery backup. This leptop is very easy to use its come with 500 gb harddisk, 2 gb ddrsd ram, intel pentium processor 2.2 ghz. its battery backup is very good I have been used from 4 year but my leptop battry still give 2.5 hr backup. Its very cheepest teptop compare than other brand. If we talk about his service & suport then acer gives thumb up service, Acer have service center in every city.
