My laptop went to hibernate and I cannot wake it from that mode. I only have a blank screen.

putting a computer to sleep is not the same as hibernation because sleep mode still is technically powered on it's just in a relaxed state or low-powered state whereas hibernation takes everything that's in Ram writes it to hard drive and then completely Powers down hope that helps

No matter which model of HP laptop you own, battery life is a big issue. Hibernation mode is designed to increase the battery life of your HP laptop by switching off the monitor, hard drive and other parts of the unit after they have been idle for a specific period of time. While hibernation mode works well most of the time, in some cases, your HP laptop may not wake from hibernation the way it should.

Docking Station Issues Many hibernation problems are caused not by the HP laptop itself but by the docking station to which it is attached. Some models of docking station interfere with the normal operation of the hibernation on the HP laptop. The easiest way to test this is to remove the laptop from the docking station and allow it to sit until hibernation begins. If hibernation mode works with the laptop undocked but not while docked, you know the problem lies with the docking station instead of the HP laptop. b> Remote Desktop Issues If you need to connect to your HP laptop from elsewhere, it is helpful to reset the power settings to the Always On mode before you leave your home or office. Many models of HP laptops do not wake properly from hibernation when users connect to them remotely using the remote desktop feature of Windows. When users connect with remote desktop, the program sends a signal to the remote computer that should wake it from hibernation and allow it to function normally. However, this process does not always work as intended with HP computers, so it helps to change the power settings to allow a seamless connection. Video Drivers Problems with HP laptop hibernation also can be caused by a corrupt or outdated video drive. HP laptops come with built-in video processors, and the drivers they use are installed during the initial setup of the unit. If there is a problem with that driver, HP releases an update, so if you see problems with hibernation, your first step should be to check for an updated video driver. b> External Keyboard and Mouse Sometimes the HP laptop does not respond properly and does not wake from hibernation when you use the built-in keyboard and touchpad mouse. The sensitivity of HP touchpads varies from model to model, and that sensitivity can be reduced over time. You can test for this problem by attaching an external keyboard and mouse to the laptop to determine whether that resolves the problem.

Go into power options, select hibernate and uncheck the box to the left, this will disable the feature, microsoft worse piece of software. This will free up disk space and improve performance, best of all no sleeping computer to wake up.

Pull out the hard drive and see if it boots, then plug the hard drive in with the machine on. Follow any messages that appear.

you can try to disable hibernation mode by going to Control Panel>Power Options Properties>Hibernate
then un check the box for Enable Hibernation, then click apply and ok.

There is a big difference between hibernate and sleep mode. One will not wake just by opening the lid. You can get a full answer from this web site:

I suggest visiting that site for a full explanation. It just might be the answer for which you are searching.

Good luck,

1. you will need to go into you BIOS settings for the mother board to disable the sleep mode.
2. You also have a " sleep mode" in your Windows environment.
Check how to in the "help and support" link at the start button or Windows Orb ( for Windows 7)

are you running vista? this is an ongoing issue with that operating system. my best advise would be to totally disable hibernate and sleep on your computer by changing the power settings.

1. right click on your desktop
2. click personalize
3. go to screen saver
4. on the lower part, you should have change power settings there
5. play around with it and disable hibernate and sleep

hope it helps.

Turn Hibernate off for one thing. Hibernation leads to registry problems and boot issues. Go to control panel > power options > hibernate tab > uncheck the box. Reboot the machine. If you want, the laptop will go into standby mode after a period of time and will wake up with a touch on the touchpad. Go back to power options and there are settings in there that you can tailor to your liking.

navigate to control Panel>>power options>>Hibernate tab and uncheck the Enable Hibernate mode and restart the system and if it still does the same then please contact your system admin
