GREAT LAPTOP BUT SHORT BATTERY LIFE

THIS LAPTOP IS VERY GOOD BUT 2 PROBLEMS, BIGGEST PROBLEM: BATTERY LIFE OF STANDARD BATTERY IS VERY SHORT. DEPENDING ON THE POWER SETTING CAN VARY BUT AVERAGE IS 2HRS. 2ND PROBLEM IS ALLOWING WINDOWS TO MANAGE THE WIRELESS CONNECTION. THE CONNECTION DROPS EVERY 3-5 MINUTES BUT IF YOU GET THE LATEST INTEL SOFTWARE FOR THE WIRELESS ADAPTER AND USE THAT TO MANAGE THE WIRELESS CONNECTION THE PROBLEM IS SOLVED. OTHERWISE GREAT LAPTOP BUT DON'T PLAN USING IN BATTERY MODE VERY LONG. SONY DOES HAVE A LARGER CAPACITY BATTERY FOR IT BUT $299!!!! HOPEFULLY THE PRICE WILL COME DOWN OR MAYBE A 3RD PARTY BATTERY WILL SOLVE THIS BUT SONY WARNS HEAVILY NOT TO USE ANY OTHER BATTERIES BUT THEIRS (TYPICAL MANUFACTURE JARGON BUT SHOULD ALWAYS BE WARY).
