Sometimes, when I press the power button to come out of hybernate the power light comes on and the hard drive is running, but there is no display. i called Lenovo today and the fellow had me hold down the power button until the computer shut down, which isn't good for Windows, but when I turned the computer back on I had the display.
Does anyone know what causes this and how to stop it from happening? This computer is a Win7 64 bit approximately 6 months old.
Solved! Go to Solution.

You may need to clear the hibernation file. (hyberfil.sys)
Here is a tip:
Then re-enable it, and see if it works properly.
Remember, Elevated command prompt.
Post back if it works or not.

Thank you for your reply. I wrote down the instructions to turn the hybernate file off and on but I have to think about doing that (I don't want to lose my hybernate).
I noticed that Lenovo has an updated display driver for my laptop (it has an integrated video driver). I was thinking of installing it but I don't know how. Can I just download the file and doubleclick on it, or is there more to it than that?
Would that be a good idea?

Here is a link for the G570 downloads and drivers. http://consumersupport.lenovo.com/au/en/DriversDow
I can't find any instructions for any of the downloads/drivers there. I did view a video which showed to install after the download, but it wasn't about any specific device. I was looking under Video > Intel Onboard Graphics Driver Win 7 64 bit. Version 220.127.116.112 dated 12-22-10. My computer has Intel HD Graphics Family Version 18.104.22.1686 dated 11-12-10.
I have sent comments to the site twice asking for info re importance of update and instructions on updating , but it's not there.
(I found bios updates there also with a tiny bit of instructions - it seems there are 4 different files you can click on - I'm totally clueless over what I would need to click on if that were necessary for me.)

I've never installed any updates relating to Display (it offers two) or USB (it offers one) - since I can't access the information for them. But I do install the important security updates regularly.
This black screen display occurring after coming out of hybernate (with the cpu running) doesn't happen frequently, but it has happened in the past.
I'm just not happy having to do a hard boot to shut down the computer. (I never reinstalled the lenovo power management - I notice they have a new one - because although I removed it, it still shows up in my Programs and Features List*. I don't know if Fn+F2 might help.)
*It is removed and if I click on Lenovo>Energy Management in my start menu Windows says "missing shortcut", but it stayed in Programs and Features because I probably didn't answer correctly when it was uninstalled.

I made a restore point and then installed Lenovo Energy Management 22.214.171.124. It said "setup will perform an upgrade of Energy Management" and was upgrading from 6.00.001 to 126.96.36.199. When it was done the Program Compatibility Assistant came up and said it may not have been installed properly. So I had it install it again and chose the "repair" feature. It reinstalled it.
Unfortunately, when I tried switch user the Lenovo Energy Management started to use 25% CPU again. I tried it with different user accounts and it again used the 25% CPU.
(I tried out a couple of fn combinations and they worked.)
EDIT: Since I made a restore point, I uninstalled version 188.8.131.52 and this time I told it to remove all devices and I'm happy to say this time it is no longer in the Programs and Features list and it's not in my Start Menu either.
I'll give the computer a rest and I'll install version 184.108.40.206 again tomorrow. I'm hoping maybe something was left over from the original energy management that caused the high CPU usage again.
