Inspiron 15 5567 laptop won't boot after cleaning the fan

Hi everyone, I have an Inspiron 15 5567 laptop I’m trying to fix, it did turn on yesterday but when taking the fan and heat sink the flex for the power button was pasted to it and it got yanked from it’s port.

There’s no visible damage on either the Flex, the contact points and the port or latch where it’s connected to, but the machine won’t turn on.

Last time i checked it it did flash the status led orange three times and then white but now it doesn’t even do that.

I’ve checked it with a multimeter, the ac Adapter gives a reading of 19.5 which it’s supposed to give, the pads on the dcin cable also read 19.5 and when connected the motherboard also reads 19.5.

And the pads on the port where the battery is connected give a reading of 12.3v

But the charging/status led stays off.

I even found the schematic,but I’m no Lewis Rossmann so I’m kinda lost, but I don’t know if i can post the link to the schematic here.

What would you all do?

I did test it with a similar 19.5 45w dell ac adaptor with no change on behaviour.

Thanks in advance and have a great day
