In this guide I will show how to disassemble a Sony Vaio VPCS111FM in order to fix broken power button.
Also, this laptop has another model number on the bottom: Model PCG-51211L.
Here’s what happened. The power button got pushed into the case and stopped working. It wasn’t possible to turn on the laptop at all.
In order to figure out what’s going on I had to disassemble the case and take a closer look at the power button.
