Dammit!
I got the replacement battery I ordered today. And tonight, I carefully pried it open (well, not very carefully; poor li’l DeadSexy will forever bear the scars of my prying it open), got the hard drive out (the connector on it it teeny-tiny)…
And it’s the wrong battery. Too big. After studying the pictures, it became obvious. They sold me the wrong battery. Or something. I don’t know, maybe, possibly, I made a mistake.
At any rate I’ll have to send it back next week and exchange it for the right one. Stupid mail-order.
