PowerPC :: 190cs - Made Start Up Sound A Few Times But Never Starts Up

I got a Powerbook 190 from my grandfather. He didn't give me the cord to plug it in with. He gave me the cord that has the big box, that connects to the computer. It was missing the cord that goes from the box to the wall. I read that it said to ONLY use an apple cord.My step dad said "that's not how electricity works." and gave me a regular, random computer cord. I was unsure, but plugged him in anyway.

He worked perfectly for one night. No problem at all. Booted up right away. I played on him for a few hours. It was time to go to bed.

He hasn't woken up since. He's made the start up sound a few times, but never starts up. I've pushed the reset button on the back a thousand times. At least what I THINK is the reset button. They just say under the video out port, but I don't know what that looks like. What I'm pressing is a small, very flat, wide (but still very small) rectangle of a button. Nothing. I've held it down for 40 seconds, 4 or 5 times. I've taken the battery out, and then held the reset button. Nothing. I've tried everything I know to do, for about a month now.

I left him alone for a few weeks. I plugged him in today, and it made the start up sound, and then nothing.

Can I save him? How? Should I try an apple-specific computer cord? Do I need a new battery? If I did, wouldn't it start up with the battery out, but still plugged into the wall? Fried motherboard?

I even found a freaking airport card that'll work with it, and an external floppy disk for my new mac, so I can transfer files from one to the other. I was so excited about him. And my dreams were crushed.
