How to Remove The Cover Of Power Adapter

By Jestine Yong on September 21, 2012

After sending out Beh's repair article on how to fix the cell phone charger there are quite a number of suggestion from fellow readers on how to properly remove the power adapter cover without destroying the cover. It is facinating to know that there are so many ways suggested and here are the ways:

1) By using a hammer and a knife

2) By using a sharp blade to open around the side

3) By using a 2 inches wide wood chisel and mallet

4) By using a big blade knife to slowly cut and have to circle it many time till it open itself (this will take time)

5) By using Gasoline/petrol (the cover will not melt but the glue holding does)

6) By using a small saw to saw open around the side

7) By placing it in a vice and hammer from outside

8 ) By using automobile "brake oil" and leave it for 15 minutes then open it with any blade knife

I'm not sure which one is the best way but I believe those who have contributed had really help those who have problem in opening the power adapter cover. If you still have other success way to open the cover please do give your comment and all of us are eager to hear from you. I'm sincerely thanking you all for the support of this blog thus making the repair line have life and always kicking!

Some technicians put the Power in the freezer for one hour, then open the cover with a hammer.

Hi Jestine
I have found that some locking system is made between top and bottom cover without any firm pasting. I had opened it by pushing a screw driver from wire side and try to open it and it opened easily without breaking any lock.

  Hi Gopal,
  
  This is true but most of it does not have any locking system thus making it hard to open .

  Hi Ibu,
  
  Thanks for the suggestion. There was a guy that I have met saying that it also depends on what type of glue they have used for the power adapter. Some cover can't be opened even with the petrol that's why the brake oil can do the trick. Do you mean everytime you use the petrol on those cover and it will be surely opened?

when I use the blade to cut around the power adaptor, usually it takes me about 5-10 minutes but the results is wonderful and you can glue it back nicely.

Hi jestine,

Bpth heat and petrol may deform the cover and components.my way is to make a cut mark round along the cealing with asmall hark saw.Then i use a sharp flat screw driver to make a hole at the cut and tswist bit by bit to open It opens faster .I file any deformed edge and return the vover with a glue after mplete repair.

HI JESTIN AND DAUD
my answer is negative i test another chrager with the braek fluid(break oil) as you said but does not effect any?!
so far the best way to open the cover of the charger is a sharp blade with force of a hammer and i found it on a big knife .
thanks

  Hi Beh.
  I used gas yesterday on a Motorola wall wart cell phone charger and it worked like a charm. I let the gas set for a few minutes, and then added a few more drops of gas and let it set for a few more minutes.

if petrol/gasoline can't melt the glue in first try, then try vinegar....

Good article, I'll try with some of the ways that were unknown for me like the brake oil and the other one: by using Gasoline/petrol.
Thanks

  Yeah, me also. On a fan I was working on, the problem that I found was an open thermal cut-off in-line fuse on the electric motor. A 115degC, 2amp. The 3 position fan speed control switch is a sealed unit just like the wall warts are.
  I wanted to take it apart to check it out and just see how it was constructed, although it checked good. I was using my Hot-Air rework station and started melting the plastic a little bit trying to heat up the glue!!
  They must be using some really tough glue. So I'm gonna try their suggestions with the gasoline and brake fluid in the next day or so.

  Thanks Najam.
  Next time I'll let the gas set longer and try to pull it apart with my fingers. I believe you are right.

  Hi Najan,
  
  Thanks for sharing, Petrol/Gasoline as a solvent is good idea, I will try it next time.
  There are some other and powerful solvents but they are dangerous as well.
