How do i turn on computer after it turn off in hibernation mode

Step 1:
Sleep Mode b> Sleep mode is primarily used with home computers (desktop computers). Sleep mode is designed to save the current work, programs, and settings of your computer using your computers memory, while using very little power. b> Hibernate Mode b> Hibernate mode is primarily used with laptop's. Hibernate mode is designed to save your computers current state on to the hard disk, then turn off your computer to stop using power completely. This mode is usually used when you do not plan on using your laptop for an extended amount of time. Benefits b> Using Hibernate mode is more power-efficient, but files may become fragmented over time by using this mode frequently. Sleep mode does consume more power, but the advantage that Sleep mode has over Hibernate is that it does not take as long to resume your computers former state when you are ready to continue using it.

Hit the space bar or enter key to wake it up. Maybe you have to pres the Power Button to wake it up.

Read the manual to see how to wake it up.

Get online and got to www.google.com In the google search box type: "Dell Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Look for Manuals on the site and search them on hibernation.

Below is what your manual says to get out of hibernation you have to press the Power Button (very last paragraph at bottom).

Hibernate Mode Hibernate mode conserves power by copying system data to a reserved area on the hard drive and then completely turning off the computer. When the computer exits hibernate mode, it returns to the same operating state it was in before entering hibernate mode.
NOTICE: You cannot remove devices or undock your computer while your computer is in hibernate mode. Your computer enters hibernate mode if the battery charge level becomes critically low.
To manually enter hibernate mode:

• Press <Fn><F1>.
  
  

or

• Click the Start button, click Turn off computer, press and hold <Shift>, and then click Hibernate.
  
  

or

• Depending on how you set the power management options on the Advanced tab in the Power Options Properties window, use one of the following methods to enter hibernate mode:
  
  
  • Press the power button.
    
    
  • Close the display.
    
    
  • Press <Fn><Esc>.
    
    

NOTE: Some PC Cards may not operate correctly after the computer exits hibernate mode. Remove and reinsert the card, or simply restart (reboot) your computer. To exit hibernate mode, press the power button. The computer may take a short time to exit hibernate mode. You cannot make the computer exit hibernate mode by pressing a key or touching the touch pad or track stick. For more information on hibernate mode, see the documentation that came with your operating system.

Hibernation may be disabled by default in XP.

Go into Start > Settings > Control Panel > Power Options. Click on the Hibernate tab, then check the Enable Hibernation check box to enable it.

Otherwise:

You can start hibernation of your PC manually, if hibernation is enabled, by:
1. Selecting 'Turn Off The Computer'' from the Start menu.
2. Normally the left choice on the resulting pop-up window is ''Stand-By''. But, if you hold down the Shift key it becomes ''Hibernate''. So holding down the Shift-Key and clicking on the resulting ''Hibernate'' button (the left-most button) will cause your computer to start hibernation mode.

Note that many computers also have a button for starting hibernation mode also. Often pressing the Power button while the computer is on will cause it to go into Hibernation. (Sometimes desktop computers have this option disabled, but it can be enabled through some Setup menu item (unless a special key has been assigned to do it on the keyboard.)


Hope helpful.

PC may be in hibernation mode or with power plug out f PC remove refit video card if it has one.

Try booting into safe mode then disable hibernation mode found in "power options"

Hibernation is a power management feature. When you hibernate a laptop, you're essentially turning it off. So, unlike Stand By (Sleep) mode, a hibernated laptop isn't using any battery power at all - that laptop is off!

The secret behind hibernation is that before you turn off the laptop, everything you're doing with the computer is saved. (The contents of memory are saved to the hard disk.) When the computer is turned on again, it recovers from hibernating by reloading all the saved information and restoring your laptop to exactly the same condition it was in before it was hibernated.

Briefly, hibernation works like this:

1. You activate the hibernation feature.

Hibernation is activated differently depending on how it's set up.

2. The laptop hums as everything in memory is saved to disk.

3. The laptop turns itself off.

It's really and truly off: The battery isn't being used, and it's safe to store the laptop or put it away until you need to use it again.

To recover from Hibernation mode, just turn the laptop on. In some cases, the laptop may recover from hibernation when you press a key or touch the mouse pad. hibernated state for as long as you want.


Hibernation mode requires hard drive space. So you should be aware that when hard drive space runs low, it's possible that Hibernation mode won't work.



In Windows XP, you have to activate Hibernation mode before you can use it. Follow these steps to activate Hibernation:

1. Click the Start button.

2. From the Start menu, choose Control Panel.

3. Open the Power Options icon in the Control Panel.

4. In the Power Options Properties dialog box, look for and click on the Hibernation tab.

If you don't see a Hibernation tab, there's your answer: The laptop isn't capable of hibernating. Oh, well.

You might want to check the laptop's Setup program to see whether you can activate Hibernation there.

5. Select the Enable Hibernation option by clicking the check box to place a check mark in the box.

6. Review other options, if they're available.

7. Click OK to confirm the changes and close the Power Options Properties dialog box.

Optionally, close the Control Panel window, as well.

Some laptops may require you to restart Windows for this change to take effect.

Hello,

Hibernate mode is a power saving feature for computers. In hibernate mode, the current state of a computer is saved to the hard disk, and the computer shuts down. A user will have to power on the computer to restore the previous settings. When a computer resumes from hibernate mode, it reads the saved settings from the disk and restores the system state as it was before it entered hibernate mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or APM-enabled, users will have to enter hibernate mode manually. Users cannot set the computer to automatically hibernate after a certain time. With ACPI-enabled and APM-enabled computers, users are able to set hibernate mode automatically

How to enable Hibernate:
Please follow this steps below to enable your Hibernate features:

1. Go to Main screen in your windows then right click your mouse to an empty area in your main menu.
2. After clicking the right click please select the properties then go to Screen Saver Tab.
3. Please Click the Button name Power then click the Hibernate Tab.
4. Please check the CheckBox name Enable Hibernation to enabled the hibernation if it is not hibernated.
5. To try test the Hibernate process please follow the steps in How to start using Hibernate below.

How to start Using Hibernate:
Please follow this steps below to active your Hibernate Features:

Make sure all necessary programs are closed prior to shutting down. Hibernating will put all programs to "sleep," but some programs won't start up properly. Experiment after this to figure out which programs perform as intended.

1. Click Start and Shut Down,
2. Point the standby button and maintain the shift key pushed,
3. A new hibernation button appears: click it while still holding the shift key: voila your PC will hibernate.

Thanks

Power management lets you reduce your Notebook power consumption. Your Notebook has two power management modes:

• Hibernation is an energy-saving feature and safeguard that saves information to the hard drive, then turns off your Notebook. When you resume from Hibernation, your information returns to the screen where you were previously working. Your Notebook hibernates when the Power button is pressed, when the battery has little power left, or when your Notebook (operating on battery power) is in Sleep mode for more than one hour.
• Sleep, also called Standby, is an energy-saving feature that reduces power to system components that are not being used. When Sleep is initiated, your information is saved in Random Access Memory (RAM), and the screen is cleared. Your Notebook is still on, but the display is blank. When you resume from Suspend, your information returns to the screen where you were previously working.

Automatically put your notebook into hibernation Windows can automatically put your computer into Hibernate mode after a specified period of inactivity. Or Windows can detect when your batteries are running low, and then automatically put your computer in Hibernate mode to save your work before the battery fails. NOTE: Using Power Options in Control Panel, you can adjust any power management option that your notebook's unique hardware configuration supports. Because these options may vary widely from computer to computer, the options described may differ from what you see. Power Options automatically detects what is available on your computer and shows you only the options that you can control. To automatically put your computer into hibernation:

1. In Category view, click Start , click Control Panel , click Performance and Maintenance , and then click Power Options . In Classic view, click Start , click Control Panel , and then click the Power Options icon.
2. Click the Hibernate tab, select the Enable hibernate support check box, and then click Apply . Figure 1: Enable hibernation check box
3. Click the Power Schemes tab, and then select a time period in System hibernates. Your computer hibernates after it has been idle for the specified amount of time.

Manually put your notebook into hibernation This feature is available only on notebooks with the Windows XP operating system installed.

1. In Category view, click Start , click Control Panel , click Performance and Maintenance , and then click Power Options . In Classic view, click Start , click Control Panel , and then click the Power Options icon.
2. Click the Hibernate tab, and then select the Enable hibernate support check box. NOTE: If the Hibernate tab is not available, your computer does not support this feature.
3. Click OK to close the Power Options dialog box.
4. Click Start , and then click Turn Off Computer . In the Turn off computer dialog box, hold down the Shift key. The Stand By button will change to Hibernate. Click Hibernate .

hi shirleygty, is that automatic hibernation (the computer hibernates by itself) or manual hibernation (by pressing the hibernate button)? If either applies to your case you might need to update the BIOS information for your computer to fix the power management issues on it. You can get it here. Just run the file, click install & choose Install From Windows. Make sure you don't have any BIOS password or any external devices connected to the computer. When the update completed successfully, your computer will automatically restart, then try hibernating this time (manual or automatic). I do recommend setting the hibernation to 1min. at the control panel > power options > change when to turn off the display. When it hibernates, pressing any keys or the power button should wake up the computer.

Hope this helps.

Please press key button CTRL + ALT + DELETE to terminate hibernate mode.

Best regards,

Philip

Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.
