You may want to check and see if your power supply in the back of the case( with the fan and green light) is going bad if this is the case ou may need to have it professionally replaced. Also have yur motherboard looked at it may play a role in the bad power supply.

Won't go into sleep mode


Which operating system ?


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


Your Computer in sleep mode


First, save all of your work. Information in computer memory is not saved while your computer is on standby.


From the Start menu, select Settings, then Control Panel, then Power Management.


Click Standby Beside When I Push the Power Button.


Push the Power button.


Automatically Putting Your Computer on Standby


Save all work before leaving your computer.


From the Start menu, select Settings, then Control Panel.


Double-click Power Management.


Set the times that you want your system to go on standby, to shut off the monitor and to shut off the hard disks.


Click OK. Your computer will go on standby according to the schedule you have entered.


Putting Your Computer in Hibernation


From the Start menu, select Settings, then Control Panel.


Double-click Power Settings.


Click on the Advanced tab.


At the When I Push the Power Button On My Computer screen, click Hibernate.


Click the Power button.


Hope this helps.

My Compaq Presario sr2050nx seems to always be running. The fans are constantly going and it seems the hard drive is always on. It won't go in to sleep mode or hibernation mode. The monitor will to to...


I recommend running a few programs to make sure that you don't have a virus, spyware or adware hiding in your system. Avast is a free anti-virus tool that is very effective. Super-anti-spyware is great for getting rid of spyware, and Adaware is a great anti-adware tool --- both of these are also free. Try downloading these programs (all 3) and run them on your computer -- this will likely get your system running like normal. Once you have run these, run a disk cleanup and defragmenter to get everything into tip-top shape.

2. windows XP check the helps or the power management in control panel.

Computer will not start


It all depends how many beeps there were.
From http://h18000.www1.hp.com/products/quickspecs/12253_div/12253_div.HTML
Diagnostic LED Explanation Table Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode

I have only really come across 4 beeps = order new Power Supply or 5 Beeps = reseat the memory and hope it works

Compaq Presario stuck in sleep mode


Connect the monitor to some other computer, e.g., a notebook, and see if it does the same thing. If it does, then the monitor is the problem.
If it does not, then your computer is not putting-out any "video" signal, and so the monitor goes to "sleep".

If you have MORE than one VGA-output port on your computer, connect your monitor to the "other" VGA port.

Or, press-and-hold the ON/OFF button on your computer, to force it to completely shutdown.

Computer not sleeping in sleep mode.


One possibility is if you have an optical/laser mouse that is on a relective surface and the mouse light is reflecting and triggering the computer to think that there is activity.

More than likely, your network card is keeping your computer from staying in sleep mode as any internet data activity is taking the computer out of sleep mode making the computer think there is activity.

There is an option in the Network Adapter properties that says to "Allow this device to wake up your computer"

Go to Control Panel and click Classic View on the left hand side

Double Click the Network and Sharing Centre Icon.

On the left hand side of the window that opens, click Manage Network Connections.

Right Click on the connected Network Connection. It is probably the Local Area Connection. Right click on it and choose Properties

A new box will open up. Click the Configure button under the Connect Using: box

Click the last tab at the top that says Power Management.

Under the Power Management tab click the square box that is beside: Allow this Device to Wake the Computer to take the checkmark out of the box. Then Click OK at the botton and close all the windows.

Let the computer go into Sleep mode and see if the computer still comes out of sleep mode on its own.

Let me know if this worked for you,
