Satellite P10 automatically goes into Standby after 15 minutes

Question

My Satellite P10 automatically goes into Standby after 15 minutes. This is a setting that is controlled by the Toshiba Power Management settings, or the Toshiba Console.
When I change the settings there the system still goes into Standby after 15 minutes. When I go to Control Panel/Performance and Maintenance/Power Options, it tells me to go to the Toshiba Power Management to change the settings, but I can still see the settings in grey stating 15 minutes standby time.
But in the Toshiba Power Management I can't seem to be able to ajust Standby settings so that they actually work. There must be a trick to it..
Can anyone help me figure it out?
Thanks a lot,

Thank you for your replies. As I now understand it there are 3 power management utilities fighting for control of the power management settings:
1) The windows OS power options("Power Option Properties, from the control panel/performance and maintenance/power options);
this utility is overridden by:
2) Toshiba Power management;
and
3) the "power save modes", activated by pressing the Function key and the F2 key, which in turn can override the Toshiba Power management.
If this last Function/F2 combination is used to change the power save modes, the windows OS power settings (which are shown in grey and cannot be changed because this is overridden by the Toshiba Power management) DO actually change.
Hold down the Function key (Fn) and press F2, holding down the Fn key. Each time you then press the F2 key again you scroll down the different "Power Schemes". The last mode is called: Toshiba Power Management. One would think that by choosing this setting the Toshiba Power management utility would effectively take over control of the power settings. Unfortunately this does not seem to be the case..
At least using this last option provides a workaround. Some of the "Power Schemes" disable the standby options.
