Computer powers down on its own

I was in Telluride and my computer started going to sleep mode on its own. I came back to sea level and it did it once, I went on line and downloaded the latest version of power management and everything was fine yesterday. Not today, I turned it on and 10 minutes later, it powered off. I thought it might be the fan, but the computer was not that hot, any suggestions?

Okay figured it out to a degree, you may have to "rollback" or return the original driver for power management, the file that you downloaded may have been bad, or the wrong operating system

Good afternoon, smarx and welcome!

You might want to check the lid switch to verify that it is working correctly. These things do go bad or can become sticky.

Hope this is of some help, and have a good day.

HP DC7800 doesn't wake up


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.

Computer won't come out of sleep


Sleep Mode Problems on a Dell Computer b> When Microsoft patched the power-saving features of Windows XP Service Pack 3 and Windows Vista, certain Dell computers were affected by various issues where the computers would go into sleep mode and be unable to come out of it or error out and not go into sleep mode. Sometimes the computers would go into sleep mode and wake up only when a USB mouse was jostled. Pressing keys on the keyboard would not wake the computer because the keyboard would stop functioning

Open the Dell support page on your Internet browser. See the link Below . http://support.dell.com/ Make sure to have your seven-digit alphanumeric (letters and numbers) service tag. Place that information into the "Choose by Service Tag" option. Make sure that the option for the "Operating System" is correct. Go to "+Bios" and click on the "+" symbol. Click on "Download" at the far right, save and run the downloaded file. Restart your computer after installing the file. Test the "Power-saving" feature once you have rebooted. b> If Section I Does Not Resolve the Issue Go to "Display Properties" by right-clicking in an open area on your desktop and left-clicking on "Properties." Click on the "Settings" tab. Check if the "Display" midway down is saying "Plug and Play Monitor on..." If it is not, go to the "Device Manager." Left-click on the "X" in the top right corner of the "Display Properties" menu. Go to "Start," left-click, and then open the "Control Panel" (or "Settings" and then "Control Panel" depending on your system is set up). Select "System," go to the "Hardware" tab, and left-click on it. Left-click on "Device Manager" about 1/3 of the way down that page. Look at "Monitors" and see a "+" symbol. Left-click on it once and see if it has an exclamation point,"!," with a yellow circle around it. If it does, right-click on the "Plug and Play Monitor" and left-click on "Update Driver." Choose "Yes, this time only" and then left-click on "Next." The wizard will update the monitor drivers automatically, if possible. Restart if necessary once updated. Test the"Sleep" mode again. The computer should go into sleep mode and then wake up successfully. b> If Section I and II Do Not Work Left-click on "Start" and then "Control Panel" (or "Settings" and then "Control Panel," depending on your system's setup).

Restart the computer and test the "Power Sleep" mode. b> If Section IV and V Do Not Work b> Find the "Windows" sidebar at the bottom right corner. Right-click on it to disable it. Test the "Sleep" mode again. If the computer does go to sleep, enable the "Windows" sidebar by going into the "Control Panel" and enabling it again. Start turning off each gadget one by one, and test the "Sleep" mode to see which gadget is causing the problem. Look at the system and see if you have a "Google" sidebar." If you do have Google sidebar, then pick only one to use, or choose not to use either of them. To remove the "Google" sidebar, left-click on "Start," then left-click on "Control Panel." Double-click on "Programs and Features." Wait for the computer to populate installed software on your computer. Find the "Google" sidebar and remove it by left clicking on it and left click "Uninstall."

Disable Sleep Mode Microsoft Windows 7 uses sleep mode for desktops and laptops to save power during times when the computer is not in use but does not need to be shut down. Sleep mode pauses and suspends your computer until you are ready to continue. In some cases, sleep mode interferes with scheduled tasks or operations such as remote desktop connections. Microsoft allows sleep mode to be turned off and disabled for users that have no need for the function or find that the feature is interfering with their normal computing activities.

Click the "Start" button to expand the Windows "Start" menu. Select "Control" panel in the right column of the "Start" menu and click "System and Security."

Double-click "Sleep" in the menu tree to expand the advanced "Sleep" options. Select "Sleep After" and use the arrow to select "Never." Select this option for both "On Battery" and "Plugged In" if you are configuring power options on a laptop. Click the small "plus" icon next to "Hibernate After" to view hibernation settings. Click the arrow to select "Never." Select "Never" for both "On Battery" and "Plugged In" if you are configuring your power options for a laptop. Click "OK" to close the advanced power options. Select "Save Changes" to save your new power management configuration. Your computer's sleep mode is disabled.

Hope it helps.

Prostart 6 button in sleep mode


Sleep mode is a convenient power-saving feature used on both laptops and desktop computers. This feature powers down hard disks, monitors, wireless devices and any other power-consuming peripherals without turning the unit completely off and necessitating a reboot. Sleep mode can prevent battery drain if using a laptop or mobile device while away from the power supply. This mode is useful when quick access to a computer is needed, but can be irritating if the sleep mode takes a long time to come back from. It is simple to turn sleep mode off, based on the operating system being used.

Go to the "Start" button, then click on "Control Panel." In the control panel screen, click "System and Maintenance," then click on "Power Options." This brings you to the "Select a power plan" page. From the "Select a power plan" page, select the option that says "Change plan settings." This changes the settings on the currently selected plan. Select the "Change advanced power settings" option. Click "Sleep" and then click on "Sleep After" to expand it. If using a laptop or mobile PC, click "On battery" and "Plugged in," then select the "Never" option. This turns off sleep mode for both battery and AC use. If you are using a desktop computer, click "Setting," click the arrow and then click "Never" to turn off sleep mode. Click "OK," then click "Save changes" to save the modification. b> Turning Off Sleep Mode - Mac OS b> Click on the Apple logo at the upper left corner of the screen to open the menu and select the "System Preferences" option. From the "System Preferences" screen, click on "Energy Saver." If you are using a desktop, select "Power Adapter" in the top drop-down menu. In the second drop-down menu, select "Custom." Highlight the "Sleep" tab, then adjust the top slider to the far right, marked "Never." I f you wish the display to stay on, adjust the bottom slider to "Never." Click the red button on the upper left side of the "Energy Saver" screen. If you are using a mobile product or laptop, follow step 2 and select "Battery" from the top drop-down menu. Repeat step 3 to change the settings for battery use. Hope this helps.

Proper shut down


Hi doodu13appa,

Nothing beats a complete "Shut Down" through the Start menu in the lower left-hand corner of your Windows screen. This allows all open windows to be properly closed, with current data saved, memory and cache cleared. This is like going to bed at night with nothing on your mind, sleeping soundly, and waking up refreshed in the morning.

Then, when the computer is powered up the next time, it will be operating at its optimum performance levels without being "bogged" down with excessive leftover garbage from previous sessions. There's nothing wrong with powering your laptop, or desktop, down by clicking the power button and letting it go into standby, sleep, or hibernate mode, much of the time. It leaves you with a quick-startup the next time you are ready to use your computer, and most of your open programs will still be running in the background. Clicking on your logon will have your right back where you last left off.
