Fan running and in power save mode

The computer is changing the screen resolution to a mode unsupported by the monitor. The "power saving" message is being generated by the monitor/tv not the computer. Check device manager and ensure that under displays, that you do not have "standard vga" I shall try and make a screenshot of what you need to look for or a youtube link.

This is a known fault with this printer.

You can try this solution:
When the printer is in the Power Save Mode is to press the number "1" key on the printer. For some people, it comes out of power save mode.

To Turn off Powersave Mode Permanently:

Using The Printers Control Panel

1. Press # and # at same time.
2. Then press 1, 2, 7, 4 in sequence.
3. Go to Underware menu. (This is the first menu that pops up after enter that sequence)
4. Go to System menu.
5. Look for System Mode Time Out and set value to 0 and press OK.
6. Press Cancel to return to the main screen.

The monitor has failed, it is almost always cheaper to replace it than fix it.

Try changing your power settings.
Go under your Control Panel. Then access your Power Options. Edit when to turn off computers display.
This should get your power save mode to prevent any errors/bugs.

If your computer is indeed running, simply unplug your monitor from the wall, and then plug it back in. This will bring your monitor out of power save mode instantly.

Hi, the Power Saving Mode, turns the screen off to conserve energy. On the remote, press Menu, and scan to Power Saving Mode. You can change the amount of time, when the Screen turn-off, the TV shut-off etc. You can set the time to (5 min) to, (never, turn-off). This should help with your problem. Thanks paul7of9

Usually hitting a button on the keyboard or moving the mouse works.

If it is really a problem go into your display settings through the control panel, access the power options and stop your monitor from going into powersave mode.

Good morning! kindly try to review/check the operations manual of your monitor as there might be proper set-up settings / compatibility requirements to a certain PC. best regards

First you need to make sure that there are no other removable devices plug on the system, like usb, external hard drives, then if that will work try to go to the bios, press f2 when you see the dell logo, and go to the system setup, go to the boot device configuration and make sure that removable device is not the first boot device, if it is the first one choose hard disk and then second boot device ad cd rom/dvd rom and then disable the 3rd boot and the fourth boot device. Make sure to save the changes. And restart the system again. Once the computer is back and running try to go to support.dell.com and check the bios, download if there is a bios update for the system.
