Not waking from sleep

Sleep or standby mode should allow your computer to conserve energy yet respond quickly to power back on when you need it. Most Toshiba laptops should exit sleep mode if you press a key on the keyboard or use the trackpad mouse. If the lid was closed, opening it should also wake up the computer. If none of these methods work to bring the computer out of sleep mode, you may have a power issue or software glitch. Causes Insufficient power can cause this problem, so try plugging in your Toshiba laptop before attempting to wake it from sleep mode. If this does not immediately fix the issue, your problem is more likely a software issue. If your laptop was shut down incorrectly prior to the sleep mode incident, it may be stuck on a blank screen that makes it appear to be in sleep mode when it actually is trying to start up.
Indications Press the power button for a few seconds to see if your computer will wake up. If it does, the laptop was not truly stuck in sleep mode, but rather went into hibernation mode. If your laptop is truly stuck in sleep mode, you may be able to force a shutdown by holding down the power button, but when you power back up it will move right back into sleep mode. In some cases, the power button may not shut down the computer from this mode at all.
Solution The best way to solve your Toshiba's problem is to completely remove all power from the laptop to ensure a fresh restart. Close the laptop's lid, turn over the unit and remove the battery. Also remove the power adapter cord from both the laptop and the wall socket. Open the laptop lid and press and hold the power button for approximately 20 seconds. This will drain any stored power in the backup battery. Wait a few seconds, then put the battery back in, plug in the laptop and press the power button to turn on the computer. It may start up with an error screen; in this case, select the option to start your computer normally. If the error recurs, start the computer in "Safe Mode" to see if a program running on your computer outside of the basic Windows operating system is causing the problem.
Further Help Sometimes this issue also requires holding down a specific key, such as "F8," when you restart. If the basic power drain and restart process doesn't work, you can use Toshiba's support website to look up further information for your specific model. Just click the "Product support" tab and enter your laptop's model information, then read through the support bulletins listed for your particular Toshiba model.

reinstall windows or go back to factory settings.

If pressing down and holding the restart/start button doesn't wake it up you might try Control + ALT + DELETE keys (together) - that will reboot it though. And if that won't work then you might have to pull the battery to reset it.

It seems that some laptops have a problem with vista and sleep mode, in particular, and sometimes hibernate too. You can try going under POWER OPTIONS under Control Panel and setting everything back to default, saving it, then resetting it again. Also it's best to avoid using sleep mode if possible to avoid problems.

If the problem developed after a recent install or updating you may need to go to an older store point to fix the problem. Personally, I just avoid using these settings as much as possible and use regular shut down and a screen saver for times when I need to step away from laptop for short periods of time.

How can I wake my computer from sleep or hibernation?

On most computers, you can resume working by pressing your computer's power button. However, not all computers are the same. You might be able to wake your computer by pressing any key on the keyboard, clicking a mouse button, or opening the lid on a laptop. Check the documentation that came with your computer or go to the manufacturer's website.

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)

Usually, to wake from sleep pr hibernate, you just need to press the "Power" button of your laptop. It will not turn it off or restart the laptop if it is in the "sleep" or hibernate mode. Pressing any key usually wake it up. The default way is to press the power button as if turning it ON for the first time.

Hello
The hinge is a very fragile part of the Macbook. In the hinge goes all the video and sound cables, as well as the backlight power. You can have a hardware problem here with your connectors.
However the sleep mode can also take its time to wake up:
- The hard dive needs to wake its 5400 rpms - The system has to wake - The video has to wake
I would think that a fast internal hard drive, as a SSD drive for example, will wake up much faster.
Hope this helps

press and hold the power button down for about 5 secs. The computer will shut down. Restart it and right click on the desktop, go to properties then look for screensaver tab , then choose power options, click on hibernation tab at the top and uncheck enable hibernation. Or choose stanby options and choose a longer time before the computer goes to sleep.

I have had similar problem. I found, by trial and error, that using Windows hibernate mode actually works every time! Windows makes a "System screen shot" and stores it on hard drive and then powers off. Just be aware that you must ensure enough hard drive space for this. I am using this mode every day now.
