I have an Acer laptop (2008 model) which doesn't boot when pressing the power button (since a few years). Interestingly after pressing the power button you've to close the lid and then gentally press the closed lid once/twice (top center of lid where back of the camera is positioned) and then it immediately boots :)

The power button is on the opposite side (at the bottom left of the lid) so it can't be getting a pressure when lid is pressed after closed.

You might want to fix that "gentally" because it is easy to misread, and the instruction becomes definitely not office-safe.
