    Long-time lurker here, but I have got a helluva problem here.....

    I have been having thermal issues for a while on my 6710b. I have done the general cleaning stuff to no avail. Lately I have focused on the exact problem with the use of RightMark CPU Clock Utility.

    - On Battery Power (no AC attached), the CPU is throttled to around 800Mhz and heat is very manageable. This is expected and I consider it functioning as advertised.

    - When battery is removed and I plug-in the computer, the CPU is screaming fast and life is wonderful

    - Here is the kicker.... When I have AC power attached AND the battery installed, the CPU Core clock slows down to 800Mhz and the the Throttled Clock speed goes to 75Mhz, ouch is that slow.

    So, does anyone have any thoughts or ideas? Right now (even though the computer works with battery) I am thinking I have a bad battery. But even with a bad battery, I would expect a functioning CPU when the bad battery is attached.

    Please help!

    Thanks,
    Sean

    Hi Sean, welcome to MBR. Just a point of order, but it is always very helpful if you post your specific system info (OS, Chipset, Processor, Video, RAM, HDD etc..) with your post so folks don’t have to go look it up. There are a lot of different HP notebooks out there…..

    That said, if I were “guessing”, like you my initial thoughts would be a bad battery. Bad batteries can cause a host of issues that seem unrelated to the battery itself. If your system runs normally without the battery, I would limit its use to that no-battery configuration as much as possible until you solve the issue. If not, you may run the risk of damaging other components.

    - How old is the battery? Dependent on use, if it is much more than 3 years old and/or has less than 30% of its original capacity, it’s likely time to replace it anyway. (Just a rule of thumb)

    - Have you run a battery check app? (If you don’t have one, try the HP app here.)

    - Have you checked your processor settings in advanced power setting?

    Best, Dave

    Bad Battery guys and girls. I am just doing a manual battery calibration right now, but if HP has an App, I will download it right now. Thanks!!!
