If the E6400 is on, you close the lid, then open the lid, is it suppose to resume?

I left the laptop on, I closed the lid, then I opened it again, but the display isn't coming back up. I have to hold the power button down and then turning it back on. Shouldn't the display come back up by itself?

 

Mine doesn't. I have to press the power button.

 

when i press the power button, the display doesn't light up. i tried Fn+F1 (to go to sleep) but that doens't work either. i can control the keyboard backlight.

 

This one also causes me problems which I haven't got round to solving since I rarely use standby. In my case I tend to press the power button which results in the computer restarting. I've now set the power properties so that Windows will ask what to do when I press the power button.

Note that if you have a BIOS password enabled then there are options for whether or not to ask for a password when resuming from standby or hibernation.

Interesting; when I open the lid on my e6400, it awakes from sleep right away. This is with Vista though; I think with XP, I had to press the power button to awake it from sleep.

Is your laptop going into hibernation or sleep/standby when you close the lid?

 

In the battery power options, you can have it set so when you close the lid it either shuts down, hibernates, sleeps, or does nothing (except turn off the screen).

It's defaulted at sleep, therefore, everything is essentially off.

What you want to do is make it so it does nothing. Go to the power options and look for Choose what closing the lid does, and select do nothing.

 

The way it seems to work for me is that by default the machine is set to sleep (when you close the lid), upon opening the lid the machine returns to its pre-lid closed state. I don't mean to contradict anyone, just this seems to be how it works, at least for me anyway.
This is all controlled in the power options (depending on Windows OS depends on how to get there, either buried in control panel or right click on desktop > properties)
