Screen stays black after laptop comes back up from hibernation
I have my laptop set to hibernate when I close the lid, which has been working fine. Recently, when I've closed the lid and then wanted to use the computer again later, the computer boots back up fine but the screen remains black. I have to shut down the computer, either by forcing it with the on/off button or by using Start-Shutdown-Shutdown, and then turn it back on again. Usually it boots up fine again. Once or twice I've had to boot it twice and then the screen is up and running. Once I'm using the computer, the screen doesn't go blank or anything, it just seems to be after hibernating/closing the lid. I did try a couple times to Start-Shutdown-Hibernate and each time I did that the computer came back up fine. And I've also noticed that most of the time (I think) I've closed the lid after watching a dvd or using Windows Media Player.
So, is this is software problem rather than a hardware problem? What should I do?

I have seen this issue before with my T60. It seemed to be related to not having restarted my laptop in a while. I used to use hibernate rather than shutting down my laptop for weeks at a time. Actually restarting my laptop seemed to get hibernate to work again.
In addition, you can check to see if for some reason the hibernate option has been disabled.
In Win XP (Win 7 is very similar):
Click Start and select Control Panel.
Double-click Power Options.
On the Hibernate Tab, ensure Enable hibernation is selected (check mark).
On the Advanced Tab, ensure that the setting for When I close the Lid is set to Hibernate (select it from the drop-down list if necessary). There should be an option for when plugged in and when on battery. Set both to your preference.
Power down the computer and power back up. Lets just shut hibernation off...you can always just have the computer sleep...it is much better on the system anyway.
Shutting Down Hibernation Go to the control panel > Power Options > Hibernation tab > uncheck hibernate…this way you save a lot of disc space and don’t have to go through all the intermittent hibernation problems that occur. After you uncheck hibernation, you can go to the other power options and change how the computer reacts to the lid being closed, when it sleeps and for how long before sleep kicks in. Make sure to change the setting for what happens when lid closes to “do nothing” this will keep the laptop alive even though you close the lid to move it, etc.
Is your computer setup to go to sleep when you close the lid?
Click on start -->control panel-->power options and then check the option that says choose what closing the lid does. You have to change this setting to 'do nothing' if you want the computer to stay on when you close the lid.
you try pressing the power button once? or maybe even pressing any keys.
also try adjusting your power management
vista) start. control panel. power option. Edit plan settings.
xp) right click anywhere. properties. screen saver tab. power management.
