T500 in sleep mode but powers on when power supply is plugged in.

2009-04-16, 14:11 PM

Hi,

 

When my T500 is in sleep mode and I plug the power supply in to charge the battery, the T500 comes out of sleep mode and powers on.

I cannot find anywhere in the power settings that would allow me to disable this feature/bug, has anyone got any ideas as to what it could be?

 

Thanks

S

I believe that option is in the BIOS under the Power Menu. I remember seeing something related to this although you might want to poke around. Just hit F1 during startup and you will get into the BIOS. That option should be disabled by default though if I remember correctly.

I am seeing the same behavior. I looked through the BIOS and could not find anything. Are you sure it's there, or is does it have a strange name or something?

 

I've also had it awake from sleep (apparently) when I just pick it up with the lid closed. Seems like there is some quirkiness in the BIOS power mgmt

I couIdn't see anything in the BIOS either. I also reset the BIOS to factory default and this did nothing.

Not sure what it is, but it's very annoying :(
