Re: have to press on/off button many times before computer starts
The times that it doesn't work (e.g., the first 14 of your 15 times today) is there _any_ noticeable reaction of the laptop from the button pushes?
If you reboot your computer using 'restart', does it ever not start back up?
If you reboot your computer using 'shutdown', wait 15 seconds, and turn it back on, is it more or less likely to respond to the first button push than if you wait, say, 15 minutes or an hour?
How old is the laptop, how much do you eat/drink/pet your cat while using it, and how hard do you tend to push buttons?
If you're having absolutely zero other problems, I'd start by looking at the physical button itself, myself.
