So i want some suggestion from you all guys of a laptop that can work for me longer. Please help me out soon.

Unless you're buying a desktop replacement, battery life is arguably the key consideration in any notebook purchase. Basically battery life is not dependent on the laptop, it is based on the batteries amps and watts.But i can suggest you some of the laptops which are known for their good battery life:-

• Lenovo ThinkPad X60s : According to one of my colleague who is using this notepad, it offers 8-hour, 16-minute battery life which is very cool.
  
  
• Dell Latitude e6500 : Its system configurations can get up to 19 hours battery life, which is a great feature for a business laptop. with e6500 you can achieve up to 19 hours of battery life with the combination of our standard 9-cell battery, new high capacity battery slice and exclusive Dell ControlPointTM software.

HP is another company focused on bringing the latest technologies to its customers and on satisfying their needs, including operating life of notebooks. So if you want a laptop with longest battery life than HP EliteBook 6930p is the best. This is the one that breaks the 24-hour Battery Life Barrier, Dell's 19 hour mark hangs its head in shame.

You can also go with Sony VAIO TX. According to sony battery life of the Sony TX is absolutely amazing.You can have anywhere from 4 to 7.5 hours of battery life with the standard battery.

Thanks a lot for the quick and valuable help friends. That is all i wanted to know. I think you have given me the best option with these four laptop brands. I was also planning to go either with Hp or Lenovo. Rest two are also better. Anyways, i appreciate your valuable help. Keep it up !!
