The simple steps of repair the Laptop heat sink / fan

A few months ago My Inspiron 6400 battery heat sink / fan went bad

. Unfortunately it was out of Dell 1 Year warranty. I called up Dell Tech support for some help, a customer sevice manager reply me with $ 1650 cost and 2 week to repair it. $ 160 is rather too expensive than my expectations. So I decide to repari it by myself.

First I spend 1 hours browsing Ebay to buy the heat sink / fan for my Inspiron 6400 (It is the same as Dell inspiron E1505 battery ). It cost me 50.39 . Let me start my heat sink/fan DIY. I briefly read some artcile about how to disassemble the Dell laptop. I compute the workload of the replace the heat sink/fan part . Obviously I can done it in 3 hours.

So I droped all the thing away, as I should to remove and replace 50 screws and even all the components of the CPU fan.

The photo above (from http://www.power-depot.co.uk) is a picture of my Dell 6400 battery. This was taken after removing the cooling unit on top. The next two photos are of all the components I had to remove.

Let's see, this photo shows the LCD, the HDD, the EMP shield, the new thermal cooling unit, and an upside down keyboard. The button panel should be hidden in there somewhere too.

Well, I reassembled the thing back together, I put some thermal paste on the stump. Almost all compounds on previous thermal heat unit were lost, so I thought I'd better do fix it.

After an hour I took whole things better, I booted the machine and it worked (which surprised me). Then I was prompted to turned if off for fear of overheating ( this happends on my last Dell inspiro 1501 battery), so I did have time to test it since it was ok.

At the moment I am in the process of setting up a dual boot of Windows and Ubuntu. And my Dell inspiron 6400 battery was back to work.
