Query: List of Consecutive Problems

I've had CPU cooling fan problems (it doesnot work) the unit becomes so hot you can probably prepare your Omelette on it. I spent lot of hours on call for service. Also I had DVDROM/CDRW Drive Problems, Keyboard Problems, Video Display Card Problems. I asked for unit replacement and they wont do it. They will change all the parts but they will not replace it. I would NOT recommend Sony Laptops to anyone. Their Customer Support is not at all Good .. Please do not get deceived by the looks or features or Software they offer. I would recommend IBM or Dell for Professional, Business or even Personal Use atleast you will have peace of mind and I am using IBM since last 4 Yrs and I havenot seen any problem and it never crashes .. so much for all the Money we Spend on this Unit is not Worth.
