Actually, I have two different questions: 1. How can I achieve the best power saving on battery? I'd tried using the Toshiba Power Saver and selected the Long Life profile. In addition, I adjusted the Screen brightness to Level 1, CPU processing speed to Level 1, Cooling Method to Battery Optimized, HDD Power OFF to 1 minute, enabled all other power saving options, switched off wireless and powered off CD-DVD. However, I left the LCD always on and disabled standby. The brand new battery had already gone through 4 times the charging and completely discharged cycle, and therefore, I believe it should be at its near maximum capacity. Is there any other things I can do? Currently, the best that I achieved is a few minutes short of 4 hours even though the machine is completetly idled. But, I read that quite a few earlier adopter had reported about 4.5 hours of actual use. It doesn't seem the battery is malfunction, I admitted that it is more likely I don't know what treaks or tricks to apply. 2. (Another question unrelated to the above) Does Toshiba provides email or telephone support that would answer technical questions? I did phone the so-called Toshiba Global Support helpline, the lady who answered my phone was either avoid answering or repeatedly saying "everything is in the manual". Also, it doesn't seems their technical staff are active in their support forum. So, please advise any contact channel other than those two? Any help is appreciated, and many thanks.
