    I noticed that my battery charge wouldn't go past 95%. Tried everything and after I removed and re-inserted the battery while the notebook was ON, battery went to 100%. I think, there's indeed some problem with the battery charge on the zv5000z. Hope it wouldn't progress...



    Second point is about AMD 64 CPU driver. I tried to upgrade the driver yesterday and used their *.exe version.

    AMD Athlon™ 64 Processor Driver for Windows XP, Version (exe) 1.1.0.14

    To my surprise, with the new driver, CPU went to 2.4 GHz and stayed there, even when on battery. Idle CPU temp went from 36C to 52C. I foud that CPU driver in my system is from...Microsoft, and dated 2002!!! So I tried to RollBack the driver - and after restart the driver was again from Microsoft. In other words, system did not actually RollBack.

    Then I downloaded the other pack from AMD (where you have to "select from specific location" rather than run *.exe)

    AMD Athlon™ 64 Processor Driver for Windows XP, Version (zip) 1.1.0.14

    Now, the driver was from AMD, dated 2004, and has PowerNOW! working again.

    Two lessons:
    1. HP shipps zv5000z (August 2004) with the same driver that is the most recent on the AMD site. No need to upgrade.
    2. If you used the self-extracting driver version and feel happy about your CPU being to full speed, better be concerned and look at the driver version that was actually installed.
