Waking up after going to sleep

In Windows 7, there is a bug, if you put the PC in sleep mode when the system is running on batteries then it may still drain out the batteries and you cannot wake it up. In this case, you need to connect the AC power and reboot the PC. If you put the Pc to slepp when the AC power was connected. Then there are no issues and just by pressing the enter key it should come out of sleep mode. Sometimes - depending upon settings - you may need to press the Power button the PC to wake it up from sleep mode.
If you have already tried all this, then please go to the Power settings in Control panel and check all the setups that exist. You may need to change some of them.

Hi, If the computer seem to wake from sleep mode for no reason? Some device settings can cause the computer to return from a power savings state when not expected. If the computer is using an optical mouse, changes in light can cause the computer to wake. Network activity can cause the network hardware to wake the computer, especially when the network is always on (like cable and DSL connections). High Definition Audio audio may also cause the computer to wake from sleep mode. Use the following steps to prevent the these hardware devices from waking the computer:

1. Click Start , and then right-click Computer .
2. Select Properties , and then click Device Manager in the left panel of the window.
3. Click the plus sign ( + ) next to the device that needs to be adjusted. If you are using an optical mouse, select Mice and other pointing devices . If the computer is using an "always-on" connection, click Network Adapters . To check the high definition audio, click Sound, video, and game controllers .
4. Double-click the name of the device to open a Properties window.
5. Click the Power Management tab, and remove the selection from Allow this device to wake the computer . Figure 6: Power management tab for a mouse NOTE: If you prevent the mouse from being able to wake the comuter, wake the computer using the Sleep button on the keyboard or from the power button on the front of the computer.
6. Click OK , close the windows that are open, and then restart the computer.
7. Click Start , and select the Sleep/Standby button to see the problem still exists: If the problem still exists, go to the next Step.
8. Disconnect all non-essential connected devices (printers, scanners, USB drives).
9. Restart the computer with only the original mouse, monitor, and keyboard connected. If this resolves the sleep/standby problem, one of the connected devices was causing the problem. Replace one device and test to see if the problem occurs again. Continue adding devices and testing until the you find the device that is causing the problem.

If you have already tried all the above steps, you can try the steps below: Many software components start up automatically and run without being seen. Most of these programs are not necessary to the work performed on a computer, but can interfere with sleep/standby mode. For troubleshooting purposes use the following steps to prevent programs from starting when Windows is first opened.

1. Click Start , and then type msconfig into the Search field and then press the Enter key.
2. The System Configuration Utility appears. Click the General tab, select Selective startup , and then and remove the check from Load startup items .
3. Click OK to accept the changes and restart the computer.
4. After completing these steps, Windows opens using Selective Startup. A small reminder may appear when Windows restarts. Select Don't show this dialog again and click OK to prevent the reminder from re-appearing every time the computer is restarted.

NOTE: To undo the changes made in this process repeat the steps above and replace the checkmark next to Load startup items .

• If disabling Load startup items did not resolve the suspend problem, go to the next step.

• If disabling Load startup items resolved the suspend problem, enable one startup item and test to see if the problem occurs again. Continue enabling startup items, until you find the software task that is causing the problem. Remove or update problem software.

If the problem still exists, go to the next Step. Upgrading the BIOS and keyboard software If the sleep button on the keyboard still does not work, go to the HP Software and Driver Download page , enter your computer model number into the field provided, and install any keyboard and BIOS updates for Windows Vista.

Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time. Click "Start" and select "Control Panel." Click "System and Security." Click "Power Options." A menu opens. Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode. If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity The computer will power-down and turn off unnecessary systems, including the monitor, while keeping the memory active so it can start back up quickly and still have all programs up that were being used prior to entering sleep mode. While this is a helpful feature that can extend the battery life of a laptop, it can result in errors where the computer won't power back up. You can usually solve the problem quickly.

Look for a sleep-specific key on the keyboard. It will usually be near the top row and have a symbol of a moon on it. Press this key as some laptops only respond to that command to come out of sleep mode. Press the "Enter" key to see if that will cause the computer to respond. Move the mouse back and forth several times and click the mouse button. Hold down the power button for 5 seconds if the previous methods have not worked. This is another common method for exiting sleep mode for many laptops. It may also trigger a full computer restart which would also solve the sleep mode problem. Unplug the laptop and remove its battery.
Reinsert the battery and then plug the laptop back in.

This should cause a full restart when the power button is pressed. Download the latest video drivers from the website for your video card manufacturer. Old drivers can sometimes cause problems with the laptop's power functions. See if your computer manufacturer has an updated BIOS on its website. The BIOS (basic input/output system) is the firmware that controls the initial boot processes for your laptop. Computer companies will release updated BIOS firmware if they get multiple complaints of boot or power problems. The BIOS interfering with Windows Power Manager is a frequent cause of sleep mode problems. Adjust your BIOS settings by rebooting the computer and pressing the appropriate function key when prompted on start up. It will normally be F1, F2 or F3, and you will often see a message during start up saying to press that key to enter the BIOS. Experiment with the BIOS settings by scrolling through the menu and locating Power Management. Increase the amount of time the BIOS allows before hibernating to make sure it is higher than the the Windows power setting. This can help eliminate conflicts between the BIOS and Windows concerning power shutdowns.

Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work. This option cuts the power to your monitor, powers down the hard drive and pauses all functions until you awaken the computer from hibernation. Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money! Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow. Mouse over the arrow. The Shut Down menu appears. Point at "Sleep" and click on this option. Your Windows 7 computer goes into sleep mode. Wake your computer from sleep mode by jiggling the mouse. There may be a delay of a few seconds before your hardware powers on. All of your open programs are still open and your work is intact, just as you left it before the computer entered sleep mode. Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time. Click "Start" and select "Control Panel." Click "System and Security." Click "Power Options." A menu opens. Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode. If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity

Is there an actual button on your keyboard that is the sleep button? Or did you put it to sleep within Windows?
If you pressed the sleep button on your keyboard, you should be able to press that button again, and it should wake up. If you pressed it within Windows, then pressing any key should wake it up.
If neither of those works, then sometimes you need to press the power button. Don't hold it down, just press it, and your computer should wake up.
Hope this helps!
Thanks for using FixYa.

Hey there, Normally simply pressing a random key on your keyboard or moving your mouse should wake it up, if it doesn't though I think the easiest way to solve this is to simply turn off the sleep mode after x amount of time.
If you have windows 7, press the start button and type in "power options", go ahead and open power options and there you will be able to set the time it takes before your PC shuts down, and you can also set it to never.


If you still wish to use this feature but just want to be able to it's a bit tricky and it won't even work for all PCs but if the keyboard waking isn't working, then it's probably because your pc does have this feature. When your PC is off, boot it up again and enter the bios by pressing F10 i believe it is for HP. And somewhere you should be able to set which devices are allowed to wake up your computer, all devices are probably disabled now, so go ahead and enable the keyboard to wake up your computer. Now save and exit, and the next time your PC goes to sleep mode you should be able to wake it up by pressing a key on your keyboard.


I hope I was able to assist. If I was, please don't forget to rate this solution.

USUALLY you cannot set your pc to wake up at a specific time..You can set it to wake up on ring (ethernet) but once the system is in sleep it takes a physical action on your part to wake it up.. sorry, it is just the way of the pc

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.

Sounds like you've tried all the obvious things. Did you check the BIOS settings and turn off all of the WAKE ON settings in there? Otherwise, it sounds like you might have a third party program which is scheduling without your knowledge (check your start up programs and running processes during normal use). If, when asleep, the machine runs a fan, it may also be waking up for the OS to receive a power or overheat warning message from the BIOS.

Problems with machines not going to sleep when asked are often related to drivers that are not unloading when asked to prepare for the sleep/hibernation process. If you have installed any new hardware (or driver heavy software like specialized encryption or hard drive management stuff) trying uninstalling it and testing the sleep functionality.

Ideas, anyway.

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