Try making sure that the power wire has a good clean connection and is securley plugged into your outlet. also try using a different cable like the power cable to your pc. if it still isnt turning on. you will need to take it to a repair shop or replace it.

Gateway a computer desktop has power but nothing on screen the computer doesn't have a tower


1) Computer doesn't have a tower? Means it is a 'pancake style' of desktop computer. A flat model.

2) No signal on monitor screen?
Good.
At least we know the monitor is good.

Problem is monitor cable, IF separate cable; or computer.

Computer isn't sending a video signal.
No Signal, Power Saver Mode, etc.

If an older CRT type monitor, (Looks like a small TV), and monitor cable is not detachable; use a known to be working monitor, and monitor cable.

If a separate monitor cable, use a monitor cable from a working computer, for a temporary test unit.
Put it back when deemed monitor cable is the problem.

Logic at this point, would deem something is wrong with the graphics chipset.
Whether mounted directly to motherboard, (Integrated), or a separate graphics adapter card. (Graphics/Video Card)

However, computer could be dirty inside, or have a bad Power Supply.

LED's (lights) light up? Maybe fans spin?
Means nothing.

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

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

3) A typical Processor can use from 51 to 130 Watts of power.
Just depends on what Processor it is.

Older desktop computer?
Ummm, 35 to 40 Watts.

That is why LED's can light, and maybe fans spin, but no computer.
NOT enough power to turn the Processor on.

Computer needs to be CLEAN on the inside. Inside of Power Supply too, as well as possible.

Proper method to do this procedure, post back in Comment if you need guidance.

Also remove ALL Ram Memory modules, and clean gold plated contact pins on bottom; with pencil eraser.
Reinstall. Make SURE they are seated in tight, and Lock 'ears' are locked in place.

Post in a Comment, as to the model number.
Example, DX4300-05. Should be on back of computer.

Dell backlight indicators


A computer monitor has a front-mounted LED that displays its current status and flashes in the event of an error. When an error occurs, the flashing may be accompanied by an error message on the screen. If the screen does not display an error message, the problem most likely falls into one of four common categories.

Unsupported Display Mode A video card has the ability to send output to the monitor at many display resolutions and refresh rates. However, no single monitor is capable of supporting every possible display mode. When the video card sends an unsupported display mode to the monitor, the monitor shuts off to prevent damage and blinks, or displays an error message. Standby Mode b> When a monitor detects no video signal from the computer, it assumes that you have turned the computer off and enters standby mode to reduce power consumption. Dell and HP monitors display an amber light when in standby mode. The status light on an Apple monitor blinks slowly. Incorrect Power Supply Some monitors such as certain Apple Cinema and Studio displays use external power adapters. Because different power adapters may have similar connectors, these monitors are designed to detect when an incorrect power supply is connected and blink the status LED rather than attempting to turn on. In the case of an Apple display, the LED blinks in an alternating short and long pattern. b> Backlight Failure b> A flat panel LCD display has an LED or fluorescent backlight that illuminates the pixels and makes it possible to see the contents of the screen. If the backlight fails and requires replacement, the monitor is unable to display any information. In some cases, you may be able to resolve this issue by turning the monitor and computer off, disconnecting and reseating all cables. If the monitor still has a backlight issue, it requires professional service.

I have a Dell Dimension E521. When I cut the power on everything comes on including the monitor, but the monitor will stay black. It does say something about power save hit any button but the screen


A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.


((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))


A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

Please disconnect the Monitor Data cable from Computer.
If you see Dell Colored bars, it means, monitor is working fine,
If still black, please ask for replacement, since Monitors have 3 years of warranty if not purchased with the computer.

Now connect the cable back to computer and turn the computer off by holding the power button on computer and turn it back on...

Blinking Green shows that computer is in sleep mode......

Hope this should resolve the issue.

Computer Won't Power Up


If the blinking amber LED is on the computer itself and not the monitor, this is most likely a power supply issue. First thing to try would be replace the power supply. If the blinking led is on the monitor, it probably has bad capacitors and needs to be replaced. (or repaired)

The power supply has most likely gone out. Check for 12v and 5v output and also the solder arround d903 and d907. The site www.lcdrepair.us sells the part as well as a repair kit and has instructions.

No Power LED and Nothing on the screen


Check your power supply to your screen cause it should at least show a amber light at the screen to show that there is power but no proper signal from the computer.

So below are step to check the power supply to your monitor. Assuming if you use a different monitor on your pc it works

1. Check your fuse both internal and external
2. check if power is receipted by the LCD
