Maybe he is refurbished? OK, for processsor I don't thing what this big problem and buy this notebook, but after 3 mounths my battery suddenly dead. Just use laptop from battery, baterry go to end, then plug adapter but it charge until 53% but don't work - if unplug adapter computer shut down in same second.
After some time I buy new battery and original adapter from US, but after 3 weeks happen the same I work with notebook from battery baterry was full, about 89% energy, but computer quick as a flash stop working. Battery again dead. Whats happen? guilty my notebook? What I must doo? How repair?
One more I saw notice - when I work from battery with SONY, it work more slowly - its normal? And the fan work with full speed.

right, first battery problems....
Remember, with time, batteries degrade, so the longer you have had the laptop and the more you use it the less time the battery will last. Also, if you do not fully decharge, then recharge the battery about once a month, it will not stay as conditioned.

Processor....
Intel Pentium 4 Mobile processors change their clock speed depending on power availability and processing load. So, although the box may say 3.2Ghz or similar it will only run at about 2.5 on battery.
My 2,5Ghz P4 runs at 1.8GHz when on battery, and sometimes runs at 1.5 or 1.2Ghz when its idling.

Hope that helps

Slightly off-topic; how do you measure the CPU speed accurately and see it change when its idling etc.? Also, i understand this is called SpeedStep (COPYRIGHT! lol) but does the standard P4 in Vaios support this?

There is a program called Mobile Monitor or something like that, in the morning i will get the program off my desktop and post a link on here to it. This graphs in real time the processor speed, battery charge level, temperature and HDD temperature.

Maybe this problem can solve if I put into the laptop slower procesor that 3.06Ghz, maybe this damage my 2 battery? My laptop must have not 3.06Ghz but 2.8Ghz procesor, maybe for this need more energy and my batery die anter 3 weeks 😞
