BE CAREFUL ! ! ZE5620US is not the computer described here.
I Bought a ZE5620US on February, and after have a lot of problems with the technical data available on site, i received a notebook with only 256mb of RAM, and Amazon's said : "Sorry, but your sole remedy is return the product and get your cash back"The described notebook is in fact ZX5040US..Amazon is able to delete my review, every day, but is unable to correct the technical data . . .And now, i have a Celeron with just 256Mb of RAM . .The notebook performance is terrible with so little memory . .I will have to expend more 60 dollars to buy the missing module.
