Windows 7 freezes coming out of hibernate

Hello All.

I have a Dell Core i5 laptop with Win 7 "home premium" ( I think)

Occasionally, it freezes after a bootup from hibernate.

It seems that this only happens if I select a login and start typing the password while the HD is still working.  The light keeps flickering on and off.
Most of the time it will show the dots hiding the password as it's typed, but not always all of them.  The curser is in the password box and is frozen in place.

However, often when this happens, the HD continues to work as if it's really booting and the screen is just frozen.

So, I stopped typing the password and hitting enter until the HD is pretty much done.

Tonight, I probably didn't wait long enough, I entered the password but did NOT hit the enter key.  It froze after 5 of 7 characters in the password box.
The mouse still works and occasionally the HD light acts like there is activity.
Ctrl-Alt-Del does nothing.  Clicking switch user does nothing.

I have work that is in an unfinished state in that login, though I'm sure I saved everything as that is a long held practice of mine.

Once booted, Win 7 seems to work just fine aside from some browser glitches.
Literally NO other OS problems.

Anyone have this happen to them?

Thanks

I recommend to update your BIOS, check Dell site for latest BIOS update. If you are familiar with BIOS setup menu, look for menu or tab to setup BIOS to default.

I wiped the HD out awhile back and reinstalled the OS.
I'm pretty sure I updated all the drivers, but I'll give it a shot.

-> Check in BIOS setup for ACPI Power settings. You want the highest state available, S3 ideally.

 -> Make sure that the network card being used is properly setup in device manager if not setup properly will cause hibernating problems see below:

1. Click Start Menu > click Run and type in devmgmt.msc. Opens Device Manager.
2. Click on Network Adapters, right click on network card and select Properties.
3. Select the Power Management tab.
4. Check the box: Allow the computer to turn off this device to save power.
5. Click OK to apply the settings.

-> In order to correct problems with the battery's power management software, follow the steps below.

    Click Start and type device in the search field, then select Device Manager .
    Expand the Batteries category.
    Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall .
    WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
    On the Device Manager taskbar, click Scan for hardware changes .
    Alternately, select Action > Scan for hardware changes .


Most of the power management problems get solved with Drivers updates or fix.
If this doesn't correct your problems it is a possibility that you may have a device driver problem.
