I want to travel with the long run laptop, because the airplane take me 24hrs to VietNam. That's why I want to upgrade from 3 cells to 6 cells battery. Please show me how to upgrade. Can I use the laptop in the airplane after upgrading?
 
Solution
Most airplanes have power outlets under the seats. Get an adapter that will work with the aircraft power outlet. Older planes had a 12VDC outlet. Newer planes (in the US) have standard household outlets.
