Guys i would like to share an experience that I had at TechnoCity. A friend of mine wanted to buy a laptop to stay in touch with his family since he is going outside soon. So he asked me to go alongwith him to help. We browsed a lot of shops and finally we found a decent laptop(a Dell D610) i think for around 15k. It had good finishing and in top notch condition. When we asked the shopkeeper about the battery time, he said i guarantee its around 1.5 hours and the battery meter on Windows XP also showed that 1 hour and 40 minutes were remaining. We had almost decided to buy it, but i wanted to check if WiFi worked in the laptop so i asked him to give me password of his Wifi network. So i connected to Wi Fi and started surfing website to check the performance of the laptop in general and all of sudden BAM! the battery goes down to 5 minutes and the laptop started showing low battery indicator. At this moment the shopkeeper was practically "speechless" and didn't even talk for some minutes as he was "caught in the act"!!
I urge you to beware of such swindlers and check laptops thoroughly before you buy.
