Hi everybody,
I would like to know how the battery performance on your Panasonic Y4?
My Y4 can stand around 3:30 hrs to 4:00 hrs only without idle (that means I keep working on that)
Setup conditions:
1. Light. 5~6 scales
2. Battery. Max performance.
3. Applications: running C# (.Net 2003), Oracle, and at least two webpages opened.
4. Cooling: put two fans beneth the laptop (with some more space to increase airflow).
5. ECO: on
6. Wireless: off
7. Internet connection: by wired.
8. Hdd: Fujitsu 80 GB 5400 rpm
Thanks for your inputs.
