macuser: Keep it and show your friends...it's a great thing to make them realise how much crap gets inside when they use it in bed/sitting on the carpet/couch

Glad you got it sorted!


Indeed!  Remember this is before I thought I got it all.  I was pulling strings of what looked like a frilly bed cover and cat hair out of the heatsink before I removed this.  It was a total mess elsewhere too.  Looked like moisture damage under the touch pad, which was actually just fine dust caught under the plastic protectant on the bottom of the motherboard.

Part of the plastic extrusion that runs down the side of the laptop to keep it stable had tapered off the closer you got to the exhaust.  It had actually melted back in to the original plastic, like someone had turned it back in to it's liquid form and smoothed it down haha!

Definitely a good result and learning experience most of all.  Will definitely be keeping an eye out for this sort of thing in the future.

DravidDavid:
macuser: I'm not sure if you separated the fan from the heat sink, but you should.  Normally it contains basically a strip of lint that is about as thick as a sock.  Usually the fan and heat sink are connected by a thermal tape.  Be careful with the tape as you'll need to stick it back over the gap when you've completed the job.


You were right...

dust

The thermal tape was not connected at all though, even before I removed the fan.  I just left it alone.

After removing the sock-like build up of dust from the heat sink, I fired the machine up and had a stable idle temperature of 32 degrees and 55 to 60 degrees under load.  Glad I spent the effort taking it apart again.  I thought the laptop had me beat.


Hmm mine is so bad it sounds like a jumbo jet and i can't find any dust ... I'll try this!

Before you rip it apart, check CoreTemp/RealTemp stats at idle and under load here so we can compare later.  Is your laptop a 4 year old DV6 by chance too?
Careful with the plastic extractor grill as you remove the top cover. (after removing the keyboard)  It gets caught in the upper body clips and snaps off easily.  If you have a different laptop, probably nothing to worry about.

From memory there is 2 small torx securing the entire housing to the board, and you can actually get away with slipping the entire thing out.  I see there you have removed the ones attaching the cover to the fan assembly and still got it stuck to the board :)

I was in poor lighting conditions (as per the photo) as the bulb under my workstation blew.  :(  I really didn't feel like re-applying my expensive thermal paste, so I took the fan assembly cover off and maneuvered the entire board where I wanted it.  It just felt easier at the time, rather than trying to find a better way, haha!

Slightly off topic, but how would one disassemble the actual LED screen itself.  I never managed to fix it when I had the laptop apart, but either the cable is damaged or the connector in the screen is bad as the backlight turns on and off when adjusting the angle of the monitor.  I'm taking a guess that the rubber bits that hold the monitor away from the top cover when closed are concealing screws, but I partially removed two and couldn't find any. Didn't look like they were designed to come off.

Is it just snapped together with plastic tabs?

I really wish I had found the video earlier.  I didn't want to risk snapping something off though.  Oh well!

You'd definitely want to be careful, there's probably potential for LCD damage if you press too hard.
