MBP won't turn on or charge, working fine last night

I've got a 2009 MBP that has been working totally fine, I was using it last night and all was well. I closed the lid, went to bed, then came out this morning to a computer that wouldn't turn on. No light on the charging cable, no response from the power button, nothing. I then plugged my MBP into another charger from my wife's MBP-- nothing. Any help would be very much appreciated!
