T60 / XP - Power button standby not working

[Muse]

I used to have this laptop set to go to sleep (which I suppose is identical to "Standby") when closing the lid. Now, I want to set it up the Do Nothing when I close the lid but I still want to be able to put it in Standby. I don't want it to go into Standby after X minutes/hours, so I have that setting disabled, same with hibernation. IOW, I want it to stay on and active indefinitely but be able to put it to sleep when I want to (manually). So, I have it set to go into Standby when I press the power button (also the Sleep button, whatever that is... what is it?). However, when I press the power button nothing happens. I tried holding it down for several seconds and the machine simply shut down. A restart hasn't resolved this. What could be wrong? Am I missing something?

The sleep button is Fn+F4 (picture of a moon) - with the power button you may have to wait a couple of seconds for it to go - it wont be instantaneous. If you hold the power button, it does a hard shut down (as you found out ). What are you using to set what you want it to do - power manager or windows settings? could you possibly try the other and see if that holds?

Waiting is not helping. I'm using Power Options either from Control Panel or Thinkvantage Configuration, doesn't matter.

I just noticed that the machine had gone into hibernation. I had had the machine set to NEVER hibernate! Without warning it had decided that it would go into suspend after 15 minutes and hibernate after 20. WTF!

I reset them the way I had them. I just tried the sleep button (Fn + F4) and that did put the machine into sleep mode. However, I'm not happy that the settings had changed behind my back.
