Stuck sleep mode

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.

This is a common problem on HP computers but also has many causes. If your laptop is not coming back on after being put into sleep mode, it could be a software issue among a few other things. If your computer has a hibernation mode I would suggest using it to get around the sleep mode issue. This mode will save everything the way it is and shut down completely. When you restart the computer it will open up just as you left it. Just like sleep mode except with a restart. This does not solve the sleep mode problem but easily provides a power saving alternative to it.

OpenControl Panel, Power settings, Advanced Power settings, change SLEEP to Never, Hibernate to never. Shut down and unplug, if you use mostly on AC, remove battery, your laptop when not in use. It will last longer, if there is a power surge not be damaged, and a reboot every day resets the computer.

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.

Sleep and hibernate options are part of Bios. what i mean by that is if these is an issue with Bios these features wont work. Sometimes there has been known issues with cordless mice and other devices plugged in via usb port. Also outdated video and other drivers will do same. i would recommend first of all going to manufacturers site and downloading latest Bios update for your system, once this is done run windows update and make sure pc is restarted once done. After all this go back to your manufacturers site and download all of the driver updates that are available. Hope this helps.

if you have a program running that is non responsive and try to shut down or restart, the computer will get stuck on the logging off screen. Often times if a computer takes a long time to do anything, it means you need to defrag your hard drive. Manually shut down the computer (you might have been pushing the Sleep button. If you can't figure it out, just unplug it and let the battery run down.) and when you restart it, go to the My Computer or Computer option, right click on your C drive, click on properties and a window should pop up. Click on the tab that says Tools and click on the Defragmentation option. The rest should be pretty self-explanatory. If nothing works. please try logging in as administrator in safe mode and doing a system restore.... please see Using Windows Vista System Restore :: the How-To Geek

It depends on how long computer is being used in a day.
for general use
you can shutdown your computer once in 2 days but i highly recommend not to put in sleep mode and betting putting in hibernate mode instead of sleep mode.
note: most of simple issues are resolved by restarting PC so you can guess now how important is to shut down computer.

Good luck,

relace the battery
