This all started as a fan replacement in my laptop. And then...
It actually started merely as trying to get to the fan to see if it had been clogged by dust, but anyways...
I attempted to do this with a Compaq Presario CQ50 laptop. I was doing all right in the opening up process, but then, when lifting up the keyboard and panel, I had to disconnect the ribbon cable from the power button to the mother board.
It looks a little messed at the power button end - a couple copper prongs seem a little off... But where I think I screwed up is at the mother board end. The cable originally slipped into a white plastic housing and seemed to be held in place from above with a long, wide piece of black plastic that just pops out but doesn't seem to pop back in.
I pretty gently pulled the ribbon cable out - took very little force for something I perhaps wasn't supposed to do. It left the black "top part" still in the white housing. When I began to suspect things had gone awry, I easily pulled the black part out of the white part. Now I can't get the black part to stay back in, nor can I get the ribbon cable secured in there.
I did my best with what I had and reassembled, but pushing the power button now does nothing.
I am presently unable to send any pictures, as this laptop being out of commission leaves me with only the backup computer I am currently using, which barely even allows me to login to and post on this forum. Anything more complicated is out of the question at the moment.
I welcome any advice and really hope I can DIY my way out of this mess.
Any help is really appreciated.
ALSO...
I am trying the "tin foil in the empty port" trick to see if I can simulate the power button being effectively pressed.
It's not working off of battery and I don't know if the battery is dead or if this laptop was even able to run from battery power (it may have deteriorated to the point where it must be plugged in the wall to even start - this has happened to me with cruddy laptops before).
My understanding is that this circuit is very low voltage... BUT...
Is it dangerous to do this tin foil trick while the computer is plugged into the wall?
I don't want to end up on the Darwin Awards, but I do want to know if the circuitry is working well enough to use this option effectively.
MINOR UPDATE:
While trying to complete the circuit at the motherboard end (placing folded tin foil where the ribbon cable from the power button should go) I did manage to get a fair bit of heat going through the tin foil into my finger (ouch).
The laptop wasn't plugged in, and this seems to suggest that it is capable of getting some power from the battery (and that I CAN complete the circuit with tin foil or other means).
However, while my finger got really hot, the laptop showed no signs of powering up. However, the laptop WOULD power up before I started this whole fan fixing fiasco.
I welcome any ideas as to why the laptop didn't beep or whir under these tin foil circumstances.
