The HP zv6000 is at the lower end of the price range for HP notebooks, but I feel it is an excellent value for all that is included. It is primarily intended to be a desktop replacement style notebook, but with 3-4 hours of zv6000 battery life, it will definitely do the job of a portable computer. The processor is an AMD desktop variant, and if you upgrade to the 64-bit AMD Athlon you will get the 939-pin chip! It is built on the 0.13 micron Newcastle core with 512kb of L2 cache which will provide excellent performance.
HP Pavilion ZV6000 Battery:
I got the 12-cell hp pavilion zv6000 laptop battery, and I have been very pleased with it so far. I ran it down the day after receiving my notebook and it took a solid four hours to get the hp zv6000 battery drained. I ran MobileMeter and the new battery already registers as having 5% wear. I assume this 5% is simply lost through the chemical breakdown in the hp zv5000 battery.
