Dell precision m6400 won't start with 210w charger
I bought a used 210w ac adapter on ebay for my m6400, and it's been working great all day. Just a few minutes ago I turned around and my laptop was off. When I went to turn it back on again the light on the ac adapter and lights on the laptop blinked and then wall went out. If I unplug the adapter and plug it back in it will light back up, but then immediately turn back off again when I try to power the lappy up.
Any ideas as to what could be wrong? This is my only laptop and I'd prefer not to lose it.
Any help is appreciated ^^

Hi DERPYHOLIC030,
Was the adapter purchased compatible or designed for use on this system model?
Based on your description, I would isolate the issue to be a fault with the adapter or the motherboard. There is some component which has shorted out and hence causing this issue. Kindly try another adapter and if it also does not work, then the motherboard needs to be replaced.
You could order the parts here if required - http://bit.ly/28VlSJB
Also, please click my DELL-username and write me a private conversation with the service tag and your Name for case records.
Let us know if you have any other queries.

Try powering it up without the battery in the laptop. Yup, just the AC power supply.

It doesn't have a battery in it in the first place, and i've tried another power supply with the same effect. I'm beginning to think it is the motherboard. I'm gonna take it in to a local shop just to be absolutely sure. If it is the mobo it's a $20 fix.

Hi DERPYHOLIC030,
Thank you for the update.
I would suspect a motherboard issue as well at this point.

So I bought a used motherboard on ebay that was tested and apparently functional from a highly rated seller, but when I installed it I'm having the same issue. Either this mobo is DOA or it's something else. This time I noticed that when I plugged in the power cable the HDD and Power LEDs turned on for a second, but when I attempted a boot it did the same thing as before.
Example video: https://youtu.be/l9xA8UP400k
could it maybe be the cpu or something? or perhaps my 210w power cable is somehow causing a surge that fries it?

Hi DERPYHOLIC030,
As per the video, the issue is with the motherboard.
As per your description, I would again suspect a motherboard issue. Since the adapter led stays on when not connected to the system and before the system is attempted to power on.
I would personally suggest you to return the motherboard and invest your money on a new machine than to repair this system. However, that is your discretion.
Let us know if you have any other queries.

So I probably just got a DOA board then?
just my luck :/
well, I can't afford a new system, so I'll just try to return this board and get another one and hope for the best

Hi DERPYHOLIC030,
Would you rather consider taking the system to a local tech to check the machine with the suspected DOA motherboard?
Just a thought.
