    DV5t - CPU Downclocks while Charging???

    When I use my DV5t off the charger I typically put it in power saving mode which downclocks my CPU to 0.80 GHz. However, when I plug it back in and change the power plan back to high performance, the CPU remains locked at 0.80 GHz while my battery is charging. The CPU remains locked at 0.80 GHz until my battery reaches roughly 85-90% charge, and then the CPU kicks back up to the full 2.40 GHz.

    This can be quite annoying when I want to play a game or watch something in HD because I have to wait for the battery to charge if I don't want stuttering.

    I figured it was an advanced power plan setting under the Processor Power Management tab, but everything I have tried has not fixed the problem. I have also tried searching through the forums, but have found nothing relating to this problem.

    Does anyone know what is causing my CPU to downclock?

    Any help is appreciated!

    Try using RMclock to override the Vista power management.

    I kinda let this thread die, but I haven't had the time to run down my battery.

    Anyways, I have been messing around with RMClock a little bit and I have found a pseudo solution. After unchecking "Enable Dynamic FSB Frequency Switching (DFFS)" I have been able to increase the CPU Clock to 1.60 Ghz while charging -- but I can still not get the full 2.40 GHz when I have tried other settings.

    Any ideas? Thanks for the help flipfire!

    The battery just hit an 80% charge a minute ago and kicked back up to 2.4 GHz right away -- I have no idea why it does this???
