white MacBook won't come out of sleep /hibernate

In last 2 weeks I was able to turn it on twice by just pressing the power button my last session was still in memory. browser was up

battery is fully charged, ac adapter plugged in.. i can hear the humming but nothing on screen and keyboard doesn't work. white light is solid. I have done all kinds of resets. Last time It came back on i changed the power setting to never to stop either hard drive or display but still it went back in sleep mode and pressing power buton does nothing. here is few lines from log i collected last time it decided to wake up.

You can also reset your power management. Remove the battery and unplug the charger. Then hold down the power button for 5 to 10 seconds. This resets power information and might be related to your sleep issue.

It is also possible that you have a bad battery/sleep cable assembly. This would give these symptoms as well.

Try resetting the PRAM (this resets the power management part of any Mac). turn off the computer, press the power button and as soon as you hear the startup noise press and hold Command + Option + P + R. The computer should turn on, light up and then turn off, KEEP HOLDING the keys until you hear the startup sound for the SECOND time. =)

Something has interrupted the MacBook in sleep mode. To fix this, press and hold the power button until the sleep light turns off then boot the MacBook up again.
