I bought dell vostro i5 3546 laptop 4 months ago. I use this laptop only for professional uses but it is legging too much and till now I has been changed 2 times of its hard disk and every time I lost my all important datas. i’m reaaly dissappointed for that. I have lost alot of my important datas of my clients and also losing too much waste of my time. when I tell to the dell customer service man that please fix this problem permanantly for this he replied me that it is a machine and we can’t do anything.
