I went to fire up my old (2008) Macbook Pro yesterday and nothing happened. I haven’t used it for a few weeks, but it ran fine up before. Here are the symptoms:

1) No response to power button

2) Battery showing 1 flashing LED when button on battery is pressed.

3) Charger shows solid green LED

I’ve tried a couple of different 85W chargers but that didn’t make a difference. I’ve reset the SMC, let it charge overnight, cleaned out the magsafe port, all to no avail.

Is there anything I forgot to try?
