Thank you all in advance for any help you can provide. I am new to this forum and I just do not know where else to turn or at least point me to the correct forums to post.

I just got my new Windows 7 Home Edition Premium 64 bit Lenovo T420 and I cannot enjoy it for the following reason. Under power options, I created a custom balanced profile and set my Processory Power Managment settings to

-100% for Maximum processor state on battery and plugged in.... and

-5% for Minimum processor state on battery and plugged in.

Everytime i put my computer to sleep, hibernate, restart, shutdown, etc the maximum processor state always resets to 5% on on both plugged in/battery,

This means I cannot enjoy my new PC at full 100% processor state ever. Is there a startup program that affects this? I am running NVidia 4200 and Intel chips.

I have troublkeshooted every setting on both to still get the same result.

Is anyone aware of have any input onto this?

Thank you so much in advance. I am really desparate. :( Lenovo support has not experienced this problem prior when I called prioirty support.

Nick

Have you updated the BIOS on that machine to the latest version available (if it hasn't been already)? I remember issues with their thinkpad line last year where resume from sleep would cause the CPU to throttle itself and not come back from throttle, even under A/C power, until a cold power down and reboot (and thus the IBM tools would set OS values incorrectly at times). A BIOS update mid to late last year fixed this problem, so make sure your BIOS is the latest if you can, and it should be very recent too.
