Finally made it to an Apple Store only to find out that it might be my power adapter that's the problem and not my PowerBook after all. This was a big relief, because the new MacBook model that I was going to buy wasn't in stock. So all I had to do was buy a new power adapter and I'd be golden. Sweet.
Except they didn't have any of the "older" power adapters in stock... they just carry the new "magnetic" version. This is pretty f#@%ing stupid. With a laptop, the only thing you need to keep it going is a power adapter. It only seems logical that such a critical element would be well-stocked to keep PowerBook users running in a time of crisis, but no.
So now I am back to square one, which sucks ass.
With no PowerBook to work with, I've scored tickets to the first ever Pet Shop Boys concert in Seattle tonight. Somehow, in their 21 years, they've missed playing here. Hopefully the wait will have been worth it...
