Problem with HP zv5000

I currently have a HP zv5000 series laptop. I am already using the bypass of the multimedia chord to power the computer because the power jack apparently went out months ago. This worked for a while but then I encountered another curious problem. I can still charge the battery using the multimedia cord and can operate the computer on battery power, but when I want to run the computer on AC power the computer starts up and shortly thereafter the fan speeds up making a louder faster noise then the computer shuts down.

I assume it is a overheating problem.

How can I fix this? Do I simply need to replace the motherboard or can I add some new thermal paste to the cpu?

Thanks

How is the charge going in through this route?

Isn't this a causality for reverse polarity?

The multimedia cord is known as something like the xc1000 and is often recommended in forums such as this as a cheaper solution than replacing the mother board or an easy fix to the power jack problem that this series and other hps have.
you can plug in a power adapter into one of the many arms of the multimedia cord and it thus powers the machine.

I just cannot imagine why a multimedia cord, designed to go out and away from the computer, would have direct access to the charging system and onboard current.

Maybe a design faux pas.

The media cable uses the same port replicator as the docking station. The docking station/media cable port is not simply a 'media-out' port, but also a 'power in' port to allow the docking station to power the laptop. This port bypasses a weak solder point between the primary power adapter and the power supply itself. This is why the XC-1000 cable (DV318a) or a standard XB-?000 docking station solves the power issue on the Pavilion Laptop.

I own two of these laptops and had the same duo of problems with both. Anyway, the shutdown problem comes from dusty/clogged fans. A simple solution is to open the machine, unscrew the metal coverings on the fans and take out the carpet that is clogging the grating where the air exits the machine. No need for thermal paste or anything like that, and definitely no need for a new motherboard. I wish I had seen this post back in July when it came up, and I hope your issue has been solved. If you replaced the laptop, I am looking for another media cable and would buy it from you if you still have it.

i have the same problem, except i still have my power cables. However, my screen swivel broke, so i need to place the screen against a wall or else it won't stand up. I decided to ditch the laptop, but recently i wanted to fix it and use it for the heck of it since it still "worked".

Thought my problem was overheating too, so i decided to stick in my housemate's laptop cooler, except it didn't help at all. My fans are still spinning but it still spontaneously shuts down... so what did i think i needed? a bigger fan!!! http://www.nextag.com/550330622p/prices-html?nxtg=12bce0a240518-0120498B8045EE11
so i set my laptop on top of this fan to "cool out the insides"... and it was working fine for a while...

Boy, so i set out to rip out the, i think it was 30+ screws and cleaned out the insides, it was dusty all right... and snapped everything back together. No luck. actually it got worse.

I think it's just HP making crappy computers, and we're just stuck with a crappy buy that didn't last me more than 2 years.

but i'm still open for suggestions... anything other than a bigger fan or cleaning out the fans. I didn't try thermal grease... because i wouldn't know where to put it. So anyone else?
