Not turning on after safe mode
1) turned on macbook 2008 unibody, it was in safe mode. Keyboard was acting up and not letting me type username/password (delete button was not working and it was really sluggish
2) selected restart
3) will not power on now. Charging light goes from green to orange within a couple seconds of hitting power button
4) tried removing battery with cable connected - light is green but still will not power on
5) held power button for 10 seconds and all held shift/option/command power button and no luck
How can I get this laptop to turn on?
