BIOS Power settings cause Vista to hang on boot

[Russ-ST24]

Hi All,
Just wondered if anyone else had noticed this.
I leave my X300 running overnight by the bed and the fan keeps blowing when on AC, if I remove the power lead it calms down.
Now I have set an identical profile in the power management from lenovo for AC and Battery called NIGHT MODE!.
But yet on AC and off the machine acts differently.
So check the BIOS and its set to "Maximum performance" for AC and "Balanced" on battery. (not got it in front of me so these discriptions may be off slightly).
So I set the AC one in the BIOS to balanced and then booted up.
Start to see the moving bars under windows and then HANGS!
Safe mode reports stops after CRCDISK.SYS but i think this not the issue.
Change it back in the BIOS and it now boots again.
Can anyone replicate this?

Thanks

Russ

well i was trying to figure out where i saw this thread. I am having the same issue on a T60 (see sig for specs). I changed it to Balanced and Vista doesn't boot at all. I have to leave it on maximum performance when on AC for it to boot plugged in.

(I haven't installed XP on this system but maybe i'll try that out oneday to see if it matters then)
