I recently bought an Alienware M11X R2 with a core i7 about a month ago.
Within the last week, I've been having issues with turning the computer on- the power button doesn't actually turn the computer on, even though it's at full battery, unless i manually plug the laptop into the power adapter.
Even when plugged into the adapter, it takes a good 5 presses on the power button to actually get the computer to light up.

Can anyone shed some light on my problem? I called Alienware and they said to take out the battery, hold the power button in for 45 seconds, then put the battery back in. This option did not work... Are there any other solutions I could try?

I work for dell, and it sounds either like ure access panel's button is dead, or that the cable plugged into it is loose.. do any of the other buttons beside it work, cant remember exakt layout of the buttons on that model, althougj ive fixed that series plenty of times hehe :-P

Hmm, well once powered ON, all the buttons work fine. It's just starting the computer up that is giving me problems.
I basically can't turn it on without having the wall power adapter plugged into the computer. Without the adapter, the computer is basically useless.

This exact same thing is happening to me. I can't believe this.
If you have any more info on the situation or resolution, please post. Thank you.

.
Does the same problem with the power button occur if instead of powering off, you put the computer to sleep? For example, does it have problems from power-off, but works every time when you press the button to "wake it up" from sleep mode? How about from hibernate mode?

If it operates differently depending on which mode it is in when you press the power button, then it could be a power management problem.

One thing I'd also try in any case, is to set ALL power management subsystems to OFF: hardware and software. Disable it in BIOS and on any and every "power control", "power management", "energy saver", etc setting available in the OS (e.g. Start>>ControlPanel>>PowerOptions>>PowerSchemes) Disable hard drive spin-down, display turn-off, etc. The power management feature of Windows has been squirrely ever since it was introduced and in my opinion has remained so and caused a lot of wasted time for some people. (note: write down your settings (and how you got to their menu panels) in case you want to go back to them if this doesn't solve your problem OR you simply want to restore them to the way they were.) If that does fix your problem, you can try re-enabling the ones you want one at a time until the problem returns (if it does...like I said, power management is squirrely on some systems/devices and simply disabling and re-enabling could "fix" such a problem).
