Hi,
I own a vaio VGN-TT11WN/B and i'm not very happy with the battery life of the computer.
Under normal use i can get 4 hours and some minutes of autonomy, but i was expecting more.
Last night, i turn off the wireless mouse that i use, a microsoft wireless presenter 8000 connected to the internet bluetooth of the laptop, and my autonomy in the vista estimated battery life, goes from 5 hours to 7 hours.
I think it can be because of the use of bluetooth, so i connect another wireless mouse, this time an logitech vx revolution, and same thing hapen, estimated battery life decreases by two hours.
I try a old microsoft optical mouse with cable, and the difference in the autonomy was about 10 minutes.
I tried in my other laptop, a dell m6400, and the use of wireless mouse, only changes about 10 minutes in battery life.
Is there any known issue with the vaio's that can cause this behaviour?, it is a little bit annoying loosing 2 hours of battery time because of a mouse.
Thanks in advance,
Bruno Almeida
