Question about Dell Dimension 4700C PC Desktop

1 Answer

Dell 4700C randomly goes into "sleep mode" and doesn't wake up.

I have a Dell 4700C and lately it has been entering into sleep mode while it is being used. The screen will go to black and the green monitor buttom will turn amber and I can tell the background programs are also frozen. The computer will not wake when I move the mouse or press a key. It either occurs randomly or when I'm using multiple programs or starting Windows. I have searched for Adware and Spyware. I have even did a clean sweep of the hard drive and reinstalled Windows. A few months ago I upgraded the memory and replaced the power supply to fix a previous problem. I don't think the new problem has anything to do with the old one but I'm not sure if this is something that can be fixed easily or if there is just too much wear and tear and I need to purchase a new pc.

Honestly, my first suggestion would have been to upgrade your memory. If you go into control panel and check your power settings (I'm assuming you're on windows XP) Do you have all of you options set to "Never"? You may also want to check your BIOS settings to see how your sleep/hibernate is set up. Aside from that, you'd have to run some hardware diagnostics to give a better idea of what to look for. Hope this helps!

How to wake Dell All in One, Win 7, from sleep mode


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.

I would say it is in the Hibernation Mode To get it out of this mode you need to go to your Control Panel, open "POWER OPTION'S" and deselect the Hibernation mode then reboot.

Monitor stuck in safe power mode


"Power Save Mode" but it tells you to press a key or whatever?

were you able to reboot the PC?

if you can reboot the PC but no screen is showing up during Windows load (you can see the hard drive activity LED lighting up and your hard drive spinning), then, youre probably have a broken monitor.


Or if your problem is you cannot wake from power saving mode (after your PC goes to sleep, then its probably just the driver for your video card). VISTA has some issues with certain drivers that the PC cannot wake from sleep. http://www.ezsystemrepairs.com/

I have a Dell Inspiron 530


I have a Dell Inspiron 530S, and it exhibited the same symptoms as rguggemos's & Wilburollie's.

I can put it to sleep, but when I try to wake it, it won't. The screen will stay black. I can hear the drives spin up, and the fans go on FULL blast, and the blue power LED stays flashing, but the computer will stay like that - no picture or anything. Then I'd have to press & hold the power button to force it off, then power back on. Not ideal.

The solution that worked for me?! On boot, at the "DELL" logo, hit F2 to enter the BIOS setup, go to Power Management, and change the standby mode from S3 to S1. The difference? S3 is a "deeper" sleep, w/ more components powered off, which is better, energy-wise, but it is more difficult to wake from. S1 is a "light" sleep. Give it a shot! Maybe it'll work!

Good luck!

Stolen from another forum:

S0 (Working) is lit. The CPU functions in entirety; the conservation of power is on a basis of by-device.

S1 (Sleep). The CPU is stopped; The RAM is regenerated; the system functions in reduced power.

S2 (Sleep 2) The CPU does not have any power; The RAM is regenerated; the system is in lower mode of the S1.

S3 (Standby) The CPU does not have any power; The RAM regenerates at minimum; the power supply unit is in mode of reduced power. This mode is also called “Save to RAM”.

S4 (Hibernate). All is powered off, but the memory was saved like temporary file on the hard drive. This mode is called “Save to disk”.

S5 (Off) Everything is shutdown. Means you need a full reboot.
