Dell Inspiron 14z-n411z turns on by itself when trying to turn it off

[jack2663]

first apology for the bad english, it is google translator.

The problem with the machine is that when trying to turn off the machine it turns off for about three seconds and then it turns on by itself
The only way to turn off the equipment and to keep it if it is to force the shutdown by keeping the power button pressed until it is turned off.

I already discarded a software problem when testing it with several linux distributions in addition to windows 7, 8.1, and 10 in all it does the same

I was suspicious of the power button, so I bought a new button, but it keeps doing the same

I hope you can help me

I am looking for the datasheet of this machine to see if I find what is not working

try to run without battery and cmos. I've had a case like that and the problem is only on cmos

Check PCI_Wake signal. Try removing lan chip and see if it helps.

no, it didn't work.
remove the lan chip and continue with the same.
I suspect the instant on, but I still can't find the schematic of my board, there is one in the forum but it is for amd and it does not match my board

Re: Dell Inspiron 14z-n411z turns on by itself when trying to turn it off

in proper working condition pci_wake# should be high or low ?
i mean if everything is ok than voltage should be available or not ?

Should be low when working ok. If it doesnt go low, pch wont turn off.
