Aww, buddy. I feel for ya. I know this one too well, being a Toshiba laptop owner myself. First you can do is test it. Do so by plugging an external monitor into the laptop. Notice the blue port on your laptop? Boot up and wait a few minutes, 'cause I know you can't see anything. Now hold down the Fn key (the next part will change video output) look up at the keys F1-F12. Look really close because you will see little symbols. Press once, on the key that looks like 2 monitors. In my case it's F5 (remember to hold down the Fn key before you push F5(?). Anyway, my guess is you should see your desktop. If this is the case, then you have a bad power inverter. Scarry- I know, halloween is just around the corner, but don't fret. The inverter is located just below the screen, right about where it say's Toshiba. I found the part online for about 60 bucks but I think if you shop ebay or somthing you can probably get it cheaper. The inverter is just a card that has 2 harnesses plugged into it. To purchase, you NEED the number off the original card. Forget about your laptop's serial number etc. Carefully remove the little rubber lid protection plugs and use a jewlers phillips screwdriver to remove the screws. GENTLY do not Force the front beezle away from the back of the lid. BEFORE DOING ANY OF THIS- SHUTDOWN-UNPLUG-REMOVE BATTERY ! (reminds me of an episode of MASH ;-)

Good luck, and it's easier than it sounds. Just be gentle.

My thinkpad went ito hibernation cant get it awake


Some laptops will wake from hibernation by touching the keypad, moving the mouse, pressing any key, pressing enter or the space bar. Some laptops will wake when you press the power button. You'll think it's rebooting, but when you look it will say Resuming Windows.

No Sound? Check your drivers, check the volume level and make sure you don't have the sound muted. You can also check your Audio and Sound properties in the device manager or control panel. If you see the megaphone at the bottom right near the time, you can right click on it to get properties.

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


you have to press the power button once to get it out of hibernation. If nothing else works you can do one of two things:

1] Press and HOLD the power button for about 5 seconds or until you hear the laptop turn off. Then turn it back on again by pressing the power button momentarily.

2] You can DISABLE hibernation. To do this - follow these steps,

  • right-click the desktop and click on and click on "properties".
  • click the screen saver tab.
  • click the power settings button
  • in the power options properties dialog box click the hibernate tab.
  • uncheck the enable hibernation check box.
  • click OK then click OK again
Hope that helps

Good Luck

Your laptop went into sleep mode/hibernate. In many cases windows could not recover from these situations. One solution is to update the BIOS of your laptop on the acer website. Easy way to fix it is setting your power options under control panel. You can configure the settings here if your pc is idle to prevent sleep mode or hibernate.

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.

Mouse reboot!


many computers only come out of hibernation only when the power button is pressed. you;ll see something that looks like booting up, and the computer will load your memoery from disk of what was in memory when you went into hibernation.

standby is the state that can be woken up by a keyboard or mouse.

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 c00035872.gif
  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 .
