    I am not sure. I am sure someone with some good experience will post but have you attempted to contact Dell about this? Also maybe try putting on stealth mode while plugged in and see what happens?

    Called support about the same issue last night. He told me...the reason you cannot go into Stealth mode is because the processor is set up to automatically cut its ability in half when on battery. So it will not let the stealth mode work since it is already cut the processors power in half. He had me download CPUID-CPU to show how it worked. With the AC adaptor plugged in…and stealth mode off…the processor multiplier is close to 20. When you turn on Stealth mode…it puts the multiplier to half that…8 or something. So he had me keep the AC adapter plugged in and turn stealth mode off…it showed the multiplier at 20+/-….then had me unplug the AC. It made the multiplier the same as it was on Stealth mode…so the processor automatically puts itself in the stealth mode state when the AC adapter is unplugged. Or that is what I was told

    Not from what he was telling me. I kept mine on performance mode when I unplugged the AC...and it still cut the processor automatically. The prob. is a way...but it would be above my head.

    It is strange....I've only had mine for about 3 days. So there may be a setting I haven't found.

    lots on this on the owner's thread, early on when the first few guys got their M15s -- stealth only works when plugged in, it is designed for air travel use only. Again, power is saved automatically when on battery power as the OP described. Not a fault, but a designed feature (or not), depending on how you view it.
