Question about HP Pavilion S3420F Slimline Desktop PC

Computer won't use sleep mode anymore

I am not a computer professional, I am just trying to figure out what the heck has happened to my computer. I have a HP Pavilion Slimline s3420f PC and it is running Vista on it. I have always just put my computer to sleep instead of shutting it down since I use it quite frequently throughout the day. About a month or so ago my computer decided it would not go to sleep anymore. I have tried just about everything I can think of in the power management settings and I even tried going into the device manager and modifying the ethernet setting and disabled the wake on lan setting but even that didn't work. Someone please help!

Go to Advance Power Settings.
Set hard drive to turn off a minute or 2 before sleep.
Set Hybrid and Hibernate modes to "Off"
Under USB settings select "Disable"
Under Multimedia select "Allow ....." also setup your screen to turn off ( pick how long monitor will stay on. you can also try going into the bios and setting it to default. save and reboot. let me know if this helps.

Screen went black but computer still


Sometime this will happen when the Dell machine is stuck in sleep mode. Press and hold to power button for about 10 seconds. You should see the fan spin just a little this tells you that sleep mode is off. now try starting the computer like normal.

Monitor won,t wake up from sleep mode


Open monitor and look at power supply board for capacitors which are "balooning" or deformed in any way. These look like cylindars on the board. These tend to dry out and make what you are describing occur. Replacing them usually fixes about 80% of the problem you are describing. Those parts run about $0.25 to $0.75 each.. well worth trying, right?

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.

Hi,

Sleep is more commonly known as Hibernation with Vista.
Sometimes certain updates or freshly installed service packs can mess with your settings, or sometimes disable the feature altogether.

Microsoft have released a fix for just this problem.

Go here to Microsoft (link below) read down the page until you see Fix this problem, click on that and then click on Run when prompted.
You should get a message saying that the problem is fixed.

Restart your computer and set your Hibernation settings.

Hope this helps and good luck

My computer will not go to stand by or sleep mode


Were you able to make the computer go to sleep mode before? Well what you can try doing is go to start, run and type msconfig, click ok. You will get the system configuration window, then go to the startup tab in the system configuration window and at the bottom of the window there is a button as disable all, click that and on the same window there are startup items, select the antivirus program and items that you would need to have at the task bar. Then click apply and ok. You will get a message to restart the computer. Click restart. As it restarts you will get a message saying that you have used the system configuration window, click do not show me the message again in the message. Also you can go to start, right click on My computer and go to properties, click the hardware tab, and select the device manager button. That would show you the device manager window. From the list of hardwares listed in the window, right click on network adaptors, properties and under the power management tab uncheck all the power options checkboxes. Now you can close all the windows and try to go to sleep mode again. You can also try disconnecting the USB devices as you try going to sleep mode and see if that works, if yes, try connecting the USB devices one at a time and check again.

Monitor goes to sleep and won't wake up


Yeah, im not sure about how to fix the problem with it shutting down like that, but one option is to go under your control panel and taking off the sleep function, or putting it on a 4 hour timer so that doesnt go into sleep mode anymore. However, the problem is not your monitor but your computer. Id just take the sleep mode off, there is no need to have it on.

Sleep mode


usually, to get a PC out of sleep mode, you either press the ESC key, press the power button a bit quickly, or press the sleep key agian. It really depends on the system. Try any of those to see if it helps.
