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

Dell xps 420 computer will no start blinking amber light no diagnostics lights working


If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location, if applicable.
Ensure that the processor power cable is securely connected to the system board.
This can be caused bya defective power supply or a defective motherboard. Just to make sure thatnothing else is causing the problem, remove any PCI cards like modem, videocard, sound card, etc... Remove the memory modules and disconnect cables toCD/DVD drives. Look at the USB ports to see if any are damaged.

I recently had a power outage for about an hour. My desktop was protected by a surge protector. After the power came on, my computer won't power up and there's no power light. However, there is a blinking...


if the system will not power on, I would suggest a new power supply as the first troubleshooting option as they are about 1/3 the price of the motherboard. The Flea Power indication on the motherboard only indicates power is reaching the board, not if all needed voltages are being received.
Normally on a Dell, if you are getting power then when you attempt to power on, you usually get a power LED indication on the power button. Solid Green/Blue is normal, Flashing Amber is Power supply bus failure, Solid Amber is normally a motherboard.
If you haven't bypassed the UPS and connected direct to the outlet, I would try that 1st, as the UPS could be the failure too.

Xp420 dell doesnt boot just a solid amber light on mother board high rpm on fan that doesnt slow no picture on screen....?????


Solid Amber light is a No-Boot scenario for all DELL PC. It may be either Power Supply, motherboard, memory or Proc. If you try to call Dell customer support they might try to let you isolate the problem by opening up your pc. But they will replace the parts necessary if they found out that its broken and your XPS is still under warranty.

You can call 1-800-232-8544 be sure to have you Service Tag or Express Service code ready.

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

My Dell XPS 420 will not turn on. Power light


Hey! Nice Computer! ( At least while it was working! Specifications show some high-end hardware parts)

Steady amber light on the Power On light, means a bad power supply.

The Dell XPS 420 uses the standard ATX style of power supply found in 90% of computers out there.
(Personal computers. Not the Cray Supercomputers!)

This is Dell Support, and the User Manual - Removing and Replacing Parts - part of the manual,

http://support.dell.com/support/edocs/systems/xps420/en/OM/HTML/parts.htm#wp1466871

From Me:

1) Computer unplugged from power, computer case open. TOUCH the metal frame BEFORE you reach inside.
Your body carries Static electricity.
Static will fry out computer hardware components.
You won't see it, or feel it.

Computer unplugged from power, you are safe.
Touch the metal frame Before reaching inside, your computer is safe.

Should you get up for any reason, walk away, then return, Touch the metal frame again)

You either have a 375 Watt, or a 425 Watt power supply.
I would recommend a power supply with more Wattage, and more Amp's on the 12 Volt power rail.

The Dell XPS 420 comes with an Intel Core2 Duo processor, or an Intel Core2 Extreme processor.

These puppy's can use a lot of power when gamin', or other intense programs are being used.

The Nvidia GeForce 8800 Series of graphics cards offered, use a lot of power when maxed out.

The motherboard with the Intel X38 motherboard chipset, uses a lot of power.

I would recommend a 600 watt power supply for a replacement.

My recommendation would be an OCZ StealthXStream 600W

Why?

1) If the temperature of this PSU is kept under 118 degrees Fahrenheit, the PSU can put out 728.8 Watts reliably. (47.9 degrees Celsuis)

2) It has Four - 12 Volt power rails.
EACH power rail can handle 18 Amps.
That's a total of 72 Amps!

3) It has all the power cables you'll need.

A) 20 + 4-pin ATX motherboard power cable
B) 8-pin 12 Volt power cable (8-pin EPS)
C) 4-pin ATX power cable
D) SATA power cables [ 3 ]
E) Peripheral power cables, (4-pin Molex) [ 6 ]
F) 6-pin PCI power cables. [ 2 ]

Replaced power supply after the old one died and now all i am getting is a solid amber light on motherboard with a green blinking light on usb port


first off double check your power connections to EVERYTHING. sometimes those connections will loosen. if those connections are fine then its a faulty power supply or there isnt enough power going to everything. double check with your motherboards manufactor and see if you have enough power for everything if you dont a bigger power supply is needed

Solid amber light. No power to the system just the fan runs.


Solid amber light means the CPU is not being powered properly, that is USUALLY a bad power supply. Contact Dell and order another power supply. if that doesnt fix it, you have a bum board. (usually, you will see popped capacitors on the board if its bad). I will say, that in about 70% of these, its a bad power supply. power supplys arent cheap (unless you have a warranty of course) but they wont break the bank. a replacement is likely going to be about 40-70 dollars. I havent priced it, but you can ask dell at dell.com/chat. Good luck.
