Power button acer v3-731 laptop - Acer Computers & Internet

Just wanted to confirm a few things..
Did you do a hard power down by holding the power button down for 5 seconds or by just briefly pressing the power button (which would put the computer to Sleep).
I've found this laptop occasionally does not properly recover from Sleeping under Win8, that's why I ask.
Either way, do a hard power down by holding the power button for 5 seconds.
Unplug the laptop and find the battery disconnect pinhole switch underneath (indicated with a picture of a battery lifted up) and using a paperclip press and hold for 30 seconds.
Try powering on again, do you atleast get the Acer logo appearing when powering on?

To turn on the computer, simply press and release the power button below the
LCD screen. Please refer to "Quick Guide" for the location of the power button.

It sounds like a short in the button itself. If you have a soldering gun, take it apart and resolder the connection. This is typical for Acer laptops.
It's either the button itself or the jack where the power supply plugs in. It's not real difficult.

i would assume somebody has to open the Laptop and replace the powerbutton. If you want to pay to have somebody do it for you there is a third party Acer Repair Service. However, if you want to do it yourself, the part is available on ebay. Here's an Acer Repair guide. Maybe a tech savy friend can do it for you.
