Hibernate doesn't work in Windows 7 64bit

Hibernate doesn't work in Windows 7 64bit. When I try to hibernate, it just turns off computer and when I turn on it, it doesn't resume and it just starts as 'fresh' again. I updated my drivers. What is the problem? Can you give me a hand? Thank you.

Come on, please help me, I really need hibernate working, 100 of my reputation will go to you. Thanks.

Edit, by the way, my model is: Inspiron N5010. After I hibernate and turn on my computer, it just show Shut down didn't shut down correctly.

Some ideas for resolving sleep and hibernation problems:

1. Disconnect any and all unnecessary devices from your PC. Pare it down to the absolute minimum : unplug anything you can disconnect, turn off and unplug the computer from the mains for a few minutes, then reboot. If the problem disappears, add the devices back while testing.


2. Look in your BIOS for the suspend ACPI options and try to switch modes among "S1 and S3", "S3" etc.


3. Turn off Hybrid sleep, see explanation here (for Vista, but is the same)


4. The hibernation file is sometimes disabled by disk cleaning, to restore do in cmd run as administrator "powercfg -h on".


5. You can use the following command to troubleshoot sleep problems and return a detailed report: powercfg -ENERGY

EDIT

The symptoms you describe don't sound right. Your computer might be infected. Better install and deep-scan using several antivirus products in addition to your current one, at least Malwarebytes Anti-Malware, but also possible are Avast and Spybot-S&D.

You can also use an antivirus online scan such as ESET Online Scanner, Trend Micro House Call and Kaspersky Labs Free Virus Scan. Please note that they might require you to use Internet Explorer as your browser as an administrator, and that each scan may take several hours.

If nothing is found, I suggest using sfc /scannow.

The last resort is Repair Install, which will refresh Windows without requiring you to reinstall any of your applications. Afterward, only total reinstall of Windows is left.

If none of these solves the problem, then this is a hardware problem, so I hope your computer is under warranty.
