Her x51 won't start
Friend lent me her X51 to check out the reason why her x51 desktop would not start up.I opened the case and checked for any loose connections, or anything else that looked amiss.
Downloaded appropriate user manuals, and followed instructions on how to start it up. Nothing. SWapped out the power cord from the ac/dc adapter. Nothing. I have no experience of testing electrical devices. With that being said, my best guess either the on/off switch is faulty, or the ac/dc adapter is faulty.
Then, it could be something totally unrelated. So, any advice from this forum would be greatly appreciated. Thanks for listening.

well as above any fans anything? or just complete dead?
the power adapter has either a blue ring were it plugs into the system, or a small green led light on the power brick itself.. is this on? ..
after having my X51 R3 take a dump early friday morning , but being under warranty doesn't bother me much, but i did figure out my issue and get it running now just awaiting response(never on weekends) from dell on how to proceed on replacement parts, or system which eitherway its gonna be fixed
if no power light is on adapter.. unplug it from machine.. then from wall for few minutes.. then plug back into wall. NOT the machine see if it lights up the light on the brick.. if it doesn't light up then adapter might be toast.. if it does.. plug it into machine.. if the light goes out, motherboard is most likely shot, or the internal dc/dc power board

Once I had a problem of not coming on for a laptop with totally OK power adapter. The only way to identify it is provide such tool to power adapter outlet socket - but make sure you do not shorten poles between each other or your power adapter will surely be cold dead! In my case the power cord after adapter got broken wire inside so even lit lamp could not show that power is not being delivered to PC!

Did you try discharge of power supply by disconnecting ALL cables from ALL ports and holding the power button to discharge. Then plug ONLY power in and press to turn on. What about the BIST button?

The computer is a model J6WFNS1. re: first first link of No power?... The
video shows two buttons, of which one engages to reset. Apparently, if
this model supposedly has such, I cannot find it on the back of the PC.
Basically, The power adapter works fine. Plugging it in, the start button
does light up. Nothing else works though. No machinery noises, such as
fans, or the usual noises when the HD starts up. I'm quite sure some
component, or other, has failed. As to what it might be, I don't know.
All I can say is the adapter works, and the start button lights up. Those
are the only two things that do.
Would appreciate your any suggestions you may have. Thanks for listening

you mean the power button light?
if so sound similar to my current issue.. except my fans reved up, video card fried.. so either find or vieo card you can test with .. even a cheap one.. or try and boot off the onboard.. after removing the discrete card..
I do believe the X51 dosent have these *reset* buttons like some full desktop version do, atleast my experience anyway
you can try a full power dissipation but unplugging and holding power button for a minute , but I'm sure this has been tried..
otherwise its possible the board failed...

re: video card recommendations to replace the Nvidia CTX 545DE.
Here's the AC Adapter specifications for this computer
Flextronics Model GA240PE1-00
Input: 100-240 Volys (52-60Hz
Output: 19.5 volts
There is no wattage listed on the adapter.
Hope this helps.

Houston, we have a solution of sorts.
Video Card is shot. Per instructions, I removed the video card, the used
HDMI cable to monitor, and HDMI to the HDMI slot on back of comp.
connected power supply, and comp started up. Checked fans, and they were
running. So now, obviously need a video card.
The computer model number is J6WFNS1, Alienware X51. Video card is huge
NVIDIA GT545DE. What do you recommend as a suitable replacement?

try to find a cheap GTX 1050. if you have a 6-Pin PCIe Power Connector available then get GTX 1050TI. with 6+2 Pin PCIe Power Connector available you can install GTX 1060. i believe you have a 240 Watts Power Supply installed so GTX 1060 is your Limit.

Thanks for your help. One question though. Must the video card be
Nvidia? I notice there are several manufacturers selling the GTX 1050ti.

Hi.
no, it doesn't matter as long as the Graphics Card fits into the X51 Case.

I do have a 6 pin connector, so I'll look for the gtx 1050ti.
