    Hi all,

    I'd like to have a question about battery mode. I tried to change settings in Power options to High performance (battery and plugged in have the same settings). But no matter what I do, clock's speed of CPU is terriblely slow (100Mhz - 200Mhz) and I can't do anything with those speeds (everything is extremely slow).

    Is there any suggestion?

    Thanks:

    You can not game on battery. The computer automatically downclocks (basically stealth mode) to preserve battery life. You want to game, stay connected.

    I'm not mentioning about gaming. When I was on the battery, even opening browsers can be very slow too :(

    30 minutes on High performance is still better than 1h with those clock speeds

    If you have gone into the advanced power profile settings and changed both minimum and maximum processor speeds to 100% for plugged in and battery modes, then I am not sure what the problem is. I don't have that issue and have not seen it reported by others.

    If you have already done the above, you can try going into BIOS and resetting to defaults to see if that helps. Perhaps one of the CPU settings in the BIOS is not correct.

    I coulda sworn I read the word gaming in your initial post, I must be seeing things. Anyways, do what fox said and it should fix your problem.

    Try using Throttlestop to lock the CPU at x9 while on battery.
