My daughter moved and now her monitor doesn't work. Are we missing a power cord? We have a cord that goes from the monitor to the hard drive and from the hard drive into the wall, but no power to the monitor.
If you look at the monitor's video cable, you should see a little pigtail coming off of it with a round connector. There is a power supply that attaches to that which in turn plugs into the wall. If you have lost it, you might be able to get one used someplace.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.
Check the cord and connections for the monitor; this has one wire that must have voltage on it or the monitor goes to sleep, and a broken wire or loose connection will fool it into thinking you are powering down. If this doesn't work try going into power options and setting monitor to never power down.
Without seeing your make or model on you monitor it is difficult to give you any advice. But with that said.. If your monitor is a flat screen there is a power cord that plugs into the wall the cord is connected to a small box (power converter) out of the box is a small connector that goes into your monitor. It is small and you may have to turn you Monitor over to see exactly where it connects.
Your computer will work whether or not you have Internet service.
Below you will find my recommendations for troubleshooting this issue:
1. Reseat the power cord and verify a good power source.
To reseat the power cord, follow the steps below:
1.1 Power down the system. 1.2 Unplug the power cord. 1.3 Wait approximately one minute. 1.4 Reseat the power cord. 1.5 Verify that the power cord is plugged directly into a known good power outlet.
2. Verify that the monitor is receiving power from a known good outlet and bypass any power strips.
To test the power outlet, perform the following steps:
2.1 Unplug the monitor power cable from the power outlet. 2.2 Plug in a different device, and verify that the device is operational. 2.3 If there is no power try another outlet. Remove any power strips and try plugging directly into the main power outlet.
3. Verify the monitor is powered on and the power button is engaged.
Ensure that the monitor is powered on and that the power button is fully engaged. To do so, check the power LED on the front of the monitor; it should be lit.
NOTE: There are two types of power switches: A mechanical switch characterized by a long travel. You have to push it further and you will hear an audible click. An electrical switch that has a short travel and almost no click.
A lit monitor LED can be any of the following:
* Green * Blinking green * Yellow * Blinking yellow * A combination, such as alternating green and yellow
Any of these states indicate the monitor is receiving power and that you should proceed.
4. Swap power cables.
To try a known good power cable on the monitor, follow the instructions below:
4.1 Turn off a working monitor. 4.2 Unplug the cable from the back of the working monitor, and unplug the cable from the wall. 4.3 Unplug the cable from the monitor in question. 4.4 Plug in the cable that came from the working monitor.
5. Run the monitor self test.
To run the monitor self test, perform the following steps:
5.1 Power off both the computer and the monitor. 5.2 Unplug the video cable from the computer or video card. 5.3 Reseat the power cord to the monitor, ensuring it is plugged into a known-good outlet. 5.4 Power on the monitor.
NOTE: The monitor self test will move around on some monitor models. If the monitor self test moves, allow it to move to the affected areas of the monitor to check for the problem described.
If the Self test failed, it's possible that the monitor is faulty. Contact dell to check if it's still under warranty so they can replace it.
I purchased a HP Pavillion Slimline computer that was accompanied by and HP flat screen monitor: HPw1858. My problem is that the power cord is missing. Can you help me locate somewhere I can purchase this cord?
I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode.
If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead.
Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.
