I know it's kinda lame, but you might be able to get something from Radio Shack. Something else to try is to look at a universal power supply. Some have interchangeable connectors and one might work. By the way, I saw in a store this weekend there are "generic" laptop power supplies that come with several different tips as well.

Trying to activate Dell P793 moniter using pc


If the monitor shows Power Saver Mode, or Sleep Mode, or No Signal; it is because it is Not receiving a Video Signal from the computer.

The monitor cable is bad, or the computer is not working.

http://support.dell.com/support/edocs/monitors/p793/En/specs.htm

http://support.dell.com/support/edocs/monitors/p793/En/index.htm

http://support.dell.com/support/edocs/monitors/p793/En/trouble.htm

The main problems with desktop computer failure is;
1) Computer is dirty inside
2) Power Supply failure
3) Ram Memory module/s ('Stick') are loose. Power unplugged from computer; FOLLOW Anti-Static Precautions; the Ram Memory module/s are removed, THEN reinstalled. Visual inspection WILL NOT DO.
(Also the gold plated contact pins should be cleaned with a pencil eraser. BOTH sides, ALL contact pins. Use air to remove eraser dust)

Just because you may see LED lights light, and Fans spin; means NOTHING.
Does NOT indicate the Power Supply is good.

A) If ALL of the LED's, (Light Emitting Diodes), were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use from 51 to 125 Watts of power. Just depends on what Processor it is. (Older Intel Pentium III's, and AMD Athlon's use less than 51 Watts of power)

This is why a Power Supply with a weak voltage power rail, can light LED's, and spin fans; but NOT have enough power to turn the Processor on.

[There are 3 main voltage power rails.
The Switched-Mode Power Supply (SMPS) in your computer is a Converter.
Converts high AC voltage, (100 to 240V AC) to 3 main low DC voltages;
3.3 Volts, 5 Volts, and 12 Volts. (DC)
In comparison two D cell flashlight batteries produce 3 Volts DC,

http://en.wikipedia.org/wiki/Computer_power_supply

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Suggestion is to test the 3 main voltages coming out of the Power Supply, with a multimeter set to DC Voltage.
You can buy an inexpensive multimeter that is plenty good enough for this job; for around $5 to $12.

OR;
Borrow a KNOWN to be good, Compatible power supply from a working computer; and use it temporarily for a test unit ]

If you are getting a video signal, and it is scrambled/distorted, post back in a Comment.

For additional questions please post in a Comment.

I can't get the power button to turn on computer


Is the button stuck? It could be a defaulted button. You may have to take it to a computer store to get it checked out.

Hi; I Have a Dell XPS 1530 which is dull if I do not have it plugged in. I have three Targus power cords and cannot use any of them. The one that has the S35 tip fits, but only engaged...


I am showing the AC adpater specifications as:
Input Voltage Range: AC 100V - 240V
Output Voltage: DC 19.5V
Output Current: 4.62A
Power: 90 Watt
Does your adapter meet those specifications?
Although I am a proponent of Targus products, possibly purchasing an OEM adapter may solve the problem. We have successfully purchased ones available from reputible vendors on eBay at a discount.
Have you checked to always show the battery status in the system tray so that you can verify when the AC adapter is actually charging versus an intermittent connection or malfunctioning power socket?

I need a power tip for the kensington power adapter for my new dell xps M1730.. I contacted Kensington and they are not much help...


In the same boat. I've contacted Dell and gave him a good talking too. They sell the Kensington, advertised as compatible with XPS when it's not. It's false advertising and should refund you.
