A restaurant owner who lives close by my shop brought this laptop for repair. He explained that the main problem was the output audio jack. The sound keeps disconnecting when he connects it to an active external speakers.

I love Lenovo computers, there are not complicated and they are very easy to take apart.

I connected it to external active speakers in my shop for testing and I could not hear any sound coming out until I pressed inward the output audio jack.

It was clear to me that that female jack inside the laptop was either loose or broken.

To get to the female audio jack inside I had to take the laptop apart and as I said, it was easy.

All the screws holding the keyboard and the other parts of the laptop were off and the inside of the laptop started to show up.

In the process of taking the laptop apart, I came across this issue. The fan was dirty and it had to be cleaned and lubricated.

Once this was done, I processed with dismantling of the laptop.

Finally, I got to the main issue of the fault. The audio female jack was broken.

I had to improvise since I do not have this kind of part in my shop. I talked to customer and informed him, that I will do a temporary but solid fix to the problem. The reason I did that because of the customer urgent need for this laptop. I checked every hardware store around and I could not find the same part and because it was Friday, half of the hardware shops were already closed.

The crack on the audio jack was not that bad. I applied carefully a little bit of heat and joined the two broken pieces together. Once it was done, I added a layer of super glue on the top where the crack was. To finish off the repair, I mixed two materials together to form some kind of epoxy and I applied it to the top of it.

A very strong epoxy was formed here and when applying it to the broken female audio plug, it was fixed and it was strong.

As you can see, this was the final result. As I put the laptop back together and connected it to an active speaker system, it played without disconnecting.

I informed the customer to try it out and at the mean time, I will order the part and install it later one. As I was informed by the customer, the repaired part is still holding and the customers of that restaurant are enjoying the food and the good music that is coming out of this laptop.

Mission accomplished.
