Tried removing battery, holding power button for 10 seconds, removing RAM, etc. - Benjamin Golub

No chime. - Benjamin Golub

Resetting the PRAM/NVRAM didn't work. It's like the Macbook is asleep. I'm going to try running the battery down. - Benjamin Golub

It's upgrade time! Are you a 13", 15" or 17" sorta guy? O_o - Adrian

Definitely sounds like the motherboard is kaput. - Adrian

Target disk mode doesn't work either. - Benjamin Golub

The worst part is I erased the sparsebundle that Time Machine was stored on in an attempt to get Time Machine working again (it hasn't backed up for like a week). That did work this morning; but the backup didn't finish before the machine got into this state :( - Benjamin Golub

It's a late 2008 Macbook Pro. Trying the SMC thing. - Benjamin Golub

SMC reset is the modern "zapping the PRAM"? - Big Joe Silenced

SMC reset didn't work. - Benjamin Golub

Is it connected to any external devices? Even a USB keyboard or mouse? - Kevin (aka ThreadKilla)

Nope. - Benjamin Golub

Yeah; appointment scheduled for this evening :( - Benjamin Golub

Apparently it's a common issue with the nvidia chipset on the logic board. They are fixing it for free! - Benjamin Golub

Oh sweet! I was going to ask if you had tried hooking it up to an external monitor. I have a 2008 MBP whose display died a similar death but it works great if you have an external display. - Akiva

External monitor didn't work. The thing isn't posting at all. - Benjamin Golub

Wow. Much worse than my situation. Although I've discovered that it's rather difficult to get people interested in buying a laptop that only works with an external monitor... - Akiva

Hi! I have the same problem... How's your macbook? Is it working? - Dana Mae
