My bluetooth keyboard and trackpad were not talking nicely with my laptop. The sales guy at the computer store said it sounded like it was time to replace my laptop but I wasn't ready to spend 1500 bucks to do that. The computer worked fine, it just would communicate with the bluetooth keyboard and trackpad at my desk. After doing some research, I learned that the antenna in the laptop could need replacing. I ordered the parts and received them after a couple days.
The repair went very well. I followed the instructions online step by step. They were very detailed and very good. I have never taken the back of a computer before much less started unscrewing and unplugging things. I followed the steps, then reversed them for putting things back and all went perfect.
If you are sure you have the right tools, buy the ones suggested in the instructions. I had to stop the repair and run to the hardware store to purchase a precision screwdriver set.
