Warranted, do you believe?

Before I used to buy something, I always used to look for the warranty and I would not buy anything without a warranty. So did happen with the purchase of my sony-vio laptop. I purchase the sony-vio laptop after seeing a warranty for 2-years in the hardware maintenance. I was quiet happy with my sony-vio laptop. I used it for 1 year without any problem. At last, one day I happen to have a problem with my sound, with my speaker. I can hear the music with headphone but not with the speaker attached with the laptop. But still I continued to use the laptop. To the addition, after 2 week I came to have a problem with my battery. The battery charges and shows up full but does not last more than 15 minutes. I was much tensed with those stuffs. Then suddenly I remember my habit of choosing the items with warranty. I check for it and found that it is warranted for 2- years, so I rushed to the seller and told them the problem. They assured me that they would try to fix the laptop and took back my laptop with my problem written in piece of paper. I was pretty much sure that they would fix my sound problem and my battery problem. They said to me that my laptop would be back by 1 or max of 2 weeks. I got a call from them after 1 months saying that they cannot repair my laptop, the battery is not covered within the warranty and for my sound problem, they did not find the suitable speaker for my laptop. Now I don’t have any other options than bringing back my laptop without fixing my problem after one months of separation from my laptop. Now I came to realize, warranty is just a policy to business man to sell the product, not to help the customer. Now it’s your time for believe on warranty. I have told my story to you, its your time for belief form warranty.
