I take it the charger is good so time to check that warranty. Many are still in warranty in that model line.
I've been having an issue with my laptop powering on, the power light stays lit for aprox 10-15 seconds and then turns off, nothing boots (screen black, no sound from fans etc).
I've tried removing the battery and removing the kinetic energy i believe (I've been reading around forums). I've tried booting with and without battery being installed and i've also removed the hard-drive.
Does anyone else have any other suggestions, i've read that removing the RAM could help, but it seems to be securely fastened in behind something.
