Windows 7 - PC freezes minutes after waking from hibernate 7RTM

I am running windows 7 Ultimate rtm on an Acer Aspire 5515 and it goes into/wakes from sleep mode just fine. However when waking from hibernation, it logs in fine and then a minute or two later, it freezes forcing me to hold down the power button to shut it off. When booted back up, of course i get the option of going into 'safe mode' hit start normally and everything is fine. I could just not use Hibernate but it would be convenient if when going to school, i could use hibernate so I still have all my battery power when i resume since sleep still uses a little of the battery up. Is there a fix for this or is it just a bug M$ will have to eventually fix through updates?

Video Adapter Name: ATI Radeon X1200 Series
Processor Name: AMD Athlon(tm) Processor 2650e
Frequency: 1600 MHz
Installed Memory: 1,789.98 MB

it does not freeze in my case.. there will be no display my dell studio laptop..happens only sometimes like 1/10 times..
i have set my power button to hibernate.. i hibernate system again and when i resume it will be normal

Tried it again tonight and it did the same thing-checked the event log and the only error that was there was saying shutdown was unexpected (because I had to hold down the power button). Its actually probably 2-3 minutes after waking from hibernate time enough to open the browser and click a favorite and the little light that shows the computer is busy continuously lights up and flashes like its really doing something then it freezes, the light goes off, the seconds in the clock stop and I have to force it to turn off. Any ideas or has everybody just given up on hibernate because they know of the bug? BTW, forgot to mention this but I am running the 32 bit version of Windows 7. One other thing, never had a problem with hibernation in Vista. Love 7 in every other way just wish the one annoyance could be fixed.

Have you tried a repair install?

In most cases, problems with hibernate are caused by corrupted video drivers.
Windows 7 has introduced a new wrinkle and the storage controller drivers also affect it now.

Update to the latest Windows 7 drivers for each of these devices (from the website of the manufacturer of the device). DON'T use Windows Update as it will, at times, install Windows Vista drivers in compatibility mode. Also, don't use the Update Driver selection in Device Manager as it just sends you to Windows Update.

To further troubleshoot it, open up Task Manager to the Processes tab (use the Ctrl-Shift-Esc key combination for this).
Click on the View menu item, then on the Select columns menu item.
Select I/O Reads and I/O Other and click on OK to save the selection.
Click on the "Show processes from all users" button in the lower left.
Expand the window so that you can see the maximum amount of the screen.

Then close Task Manager using the File...Exit menu item.
Relaunch it to make sure that it shows up this way (if needed later on).
Then hibernate the system, wake it up and watch the numbers in Task Manager as the system freezes.
Let us know the image names of any processes that are consuming excessive amounts of resources.
