If you didn't open the case and move any jumpers try this.
Remove power from the PC and hold in the power button up to one minute to discharge the motherboard.

DELL DIMENSION 2350 L'ADMINISTRACTOR IS LOCK


You can use Hiren's Boot CD to reset the administrator password. Download it and burn it on a CD. Boot from CD when computer starts up and go to Password Tools, and use one of the Windows utilities from there (you can choose from more: Password Renew 1.1, NTPWD, WinKeyFinder 1.73, Offline NT Password Changer 2010-06-27).

Dell 2350:when i push cpu button,the green light blinks for 1 second and cpu and moniter does not go on. same thing happenns with the moniter.


Reseat your memory card first. But unplug the unit first from power. Discharge your static by touching the bare metal case of your CPU before doing that.

Second try is to clean it using soft eraser the contact edge of it. Or have a good spare to test.

Model name BLUFORD. E139765 motherboard. I need J16 pin layout for the power switch, reset switch, etc. Dell is not very helpful with this paticular board for some reason. Thank You for any info. DW


This is what I found after extensive searching,

......................O
.PWR LED- O O
.HDD LED- O O HDD LED+
.................... O O

.................... O O PWR LED+
.................... O O

.CON CNT O O CON CNT

Looks pretty lame, huh? I found this on Dell's Community Forum.
I gather, this motherboard was used in the Dell Dimension 2350.

http://support.dell.com/support/edocs/systems/dim2350/techov.htm#1101565

Looking, at what Dell has for the layout of the Dimension 2350 motherboard, there are 20 pins in the J16 header, just like he has crudely shown above. I don't see one missing in the corner, though. Of course, the link above is a crude example from Dell.

This person stated it was for the J24 header on the motherboard. Also stated that it was the Front Panel I/O header. (At least that's what was stated) I believe he was confused with the Control Panel header J24. Hopefully it is for the J16 Front Panel I/O header, as it has the Power On switch, HDD activity LED, Power LED, and so on.

Indications are that the O's represent the pins. There was a statement of taking -> Note, that there is a missing pin in the upper corner, and this orients the connector view, Orients, how you are looking at the connector. Only you will know for sure. I don't have this motherboard in front of me. Dell ISN'T giving ANY info out.

This person had the Bluford E139765 motherboard, in a Dell Dimension 2350.

The statement was also made, that there is a Brown jumper wire that connects the two CON CNT pins together, but didn't know if this jumper is required, as this person is putting this motherboard, into an aftermarket computer case. (?)

Solution?
What I would do.
I would have the power supply plugged in. I would use an LED lamp, with two wire leads attached to it. Leads of about two inches long, or more. (Borrow one out of the Front Panel, or from another parts computer?)

Twist the ends of the lead wires tightly. I would then touch the leads to two pins. Should they be power Out pins, (HDD activity lamp pins. Power LED pins, and so on), the light will light up, and not short out the two pins touched.

(If the LED light doesn't light up, no biggie. It just means the wires need to be reversed. Bear this in mind, when you go to hook the LED's up)

When the two pins for the Power On is found, the computer will turn on.

Judging by the crude diagram the missing pin is on the upper right.
Only you will know for sure, as the J16 header should have a flat place in one corner, where a pin would go. NO pin.

If so, this is what I see.

Processor to the left, PCI slots to the right, J16 header on the right, above the PCI slots. The header goes along the edge of the motherboard, lengthwise.

I'll number the pins like this.
Starting at the Top Left, and going down the Left side.
Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.

Starting at the Top Right, and going down the Right side.
NO pin, (Would have been Pin 2),
Pins 4, 6, 8, 10, 12, 14, 16, 18, and 20

Pins 3 and 4 are for the Power LED. (Confusion here)

Pins 5 and 6 are for the harddrive activity LED. PIn 6 is for the + wire/

NO connection to Pins 7, 8, 9, and 10

Pins 11 and 12 are for the Power LED.
(Which ones to use? Pins 11 and 12, or Pins 3 and 4? I leave it up to you to test as the computer is on, and see)

NO connection to Pins 13 and 14

Pins 15 and 16 are for the Power On switch.

NO connection to Pins 17 and 18.

Pins 19 and 20 are for that jumper wire he mentioned. I would try it without it. If the computer doesn't come on, or something doesn't work, like the harddrive for example, I would unplug the computer from power, then attach this jumper. Plug in, and see if everything works.

Motherboard powers up for 2 seconds then down on dell dimension 2350 fans start then immediately go down...pulled power supply and replaced but still same problem


if you have the knowhow, do the following

remove your CPU fan which comes with a heatsink,

then apply some heat sink compound paste on your heatsink where the heatsink makes contact with your CPU.
then connect your heatsink and fan, lock them into position and turn on your PC.

helpful? if not give me a reply to give you other ideas.
