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.

What is correct way to start computer back up from sleep mode


Unless you have set up differently, press the power button for no more than 1 second.

How to Shutdown or Turn off your Computer Properly



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. On your laptop, usually just tapping the Power Button will perform the same function as the following instructions.
When doing this, click on the 69966d5.jpg symbol just to the right of the Start button. This allows all open windows to be suspended properly, with current data saved. When you startup the next morning, your open programs will still be running in the background. Clicking on your logon will have your right back where you left off.
If you see the same symbol with the exclamation mark 15ca2e0.jpg, click and leave the computer alone, because it will be in the process of installing important updates before shutting down.

Nothing beats a complete "Shut Down" through the Start menu in the lower left-hand corner of your Windows screen. Mouse-over to the far right icon, and click on Shut Down in the popup window. All your open programs will be closed properly, data saved, and 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. It leaves you with a fresh start-up the next time you are ready to use your computer.

To summarize, tapping the Power button most of the time, and allowing the computer to enter sleep mode, is fine. Occasionally, do a complete Shut Down to clear everything out of memory. Your laptop/desktop will thank you...lol.

Acer one with windows 7 ultimate fall into sleep mode


A laptop computer is typically set to conserve battery power. One of the common settings called standby, sleep mode or hibernation turns off power to the screen and the laptop itself after a preset time limit passes without any mouse or keyboard activity. It can be inconvenient for the computer to shut down while you're working on an open page or during a download. Change the setting if you don't want your laptop to going into automatic shutdowns

Turn the laptop computer on with the power button if it's not set to turn on upon opening. Allow the system to boot up. Open the panel for adjusting the sleep settings. This varies among the popular versions of Windows operating systems. To change the sleep mode setting on a laptop running Windows XP, click the "Start" button, and click the "Control Panel" selection. Choose the "Performance and Maintenance" selection, and click on "Power Options." Click the "Power Schemes" tab, and click the drop downs next to "Turn Off Monitor," "Turn Off Hard Disk," "System Standby" and "System Hibernates." Select "Never" for each drop down in both the "Plugged in" and "Running on Battery Power" columns. Click the "Hibernate" tab and click to remove the check mark in the box next to "Enable Hibernation." To change the sleep settings on a Windows Vista laptop, click "Start," "Control Panel," "Systems and Maintenance" and "Power Options." Then click "Change Plan Settings" under the currently established plan. Click on the "Advanced Settings" tab and select the "Never" option on the "Sleep," "Sleep After," "Hibernate After," "Display" and "Turn off Display After" drop downs. Click the "OK" and "Save Changes" buttons to confirm the settings. To change the sleep settings on a laptop running Windows 7, click the "Start" button, choose "All Control Panel Items," select "Power Options" and click "Edit Plan Settings." Click the drop downs for "Turn off the Display" and "Put the Computer to Sleep." Choose "Never" for both and click the "Save Changes" button.

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.

I would need some more information to completely help you. When you say you walk away and the pc shuts down and starts back up, does it close down (reboot) or does it go into screen saver / sleep mode? What button did you push for the power button light to blink? Have you put the PC into sleep / hibernation mode by pressing the power button once.

Screen brightness keeps going down.


its because it has gone into power saving mode, you need to go into the power/battery settings and set the brightness at 100% and then choose that setting as default.
