    I have a Sony Vaio SR, and on battery (in High Performance mode on Windows 7), the maximum CPU speed is 1.5 Ghz, the real maximum is 2.53 Ghz. On the battery it won't go higher than the 6.0 multiplier, but on the AC, it goes to the maximum of 9.5. Does Sony lock their laptop multipliers in the BIOS? move!

    Did you set your SR to silence mode in Vaio Control Center?

    It's set to "performance" in the Vaio Control Center. Throttlestop won't even get it to 9.5. This is ridiculous.

    No one can confirm or deny this?

    On the Z11 there is a configuration menu for "power saver" "balanced" and "performance" settings. In this menu you can choose to use the processor at min or max XX% of it's capacities.
    I know that as I set power saver mode to max 80% performances of my i5 540M the processor will not use turbo boost when this mode is selected.
    Maybe there is something similar for your system.

    I already observed something similar on my old Asus F3 for which power saver mode regulate the processor max frequency.

    The HP Envy's also indicated this "issue" as well. CPU throttling on battery. That is truly sad. They should offer the option for the user, not make it a hard setting.

    Isn't this ironic. I recently (not recently enough, past my return period!) discovered the same behavior on my HP Envy 15. Used it for about a month, thought the occasional sluggishness was due to the very bloated stock HP OS, shrugged it off and said to myself it'll be fixed when I get around to wiping the OS. Nope, the multiplier is positively stuck at 9x on battery, runs at a fixed 1.2GHz. Got me PO'ed, stopped at the store to look at other laptops and stumbled on the Z. First thing I did, you guessed it, make sure it can run the CPU on max on battery power when I took it out of the box. It does.

    Have had the same problem on vaio-ar, been talking to sony for ages who denied the problem...to fix the problem disable the thermal protection 1 and 2 using RMclock, then you can run on battery with the processor scaling to the max!

    Yes it's sad. My VAIO F11 with i7-720QM runs at 900MHZ each according to CPU-Z when on battery

    lol much

    My HP G60 laptop can run at full clock speed on battery. I will also test my sony when it arrives.

    Somewhere buried in these forums, someone said it was the battery technology used that didn't all for the power draw required to run at full speed. I don't know if there's any truth to that. Some sort of polymer battery.
