I've got an Acer Aspire 5538-1096 that will not power on if the power button is mounted to the power panel. If I remove the power button from the panel and plug it in to the motherboard without the plastic piece, it powers up and runs just fine. But as soon as it is mounted, you can press the button as many times as you like and it will never power up. I'm pretty sure I've verified that there is nothing shorting when the panel is on, the button itself is definitely activating the switch ... I'm at a loss. I've even tried a second panel just to make sure and the second panel does the exact same thing.
Anyone have any ideas?
