My MacBook wouldn't run

Hi,

Since yesterday this problem appear suddenly after I decide to pull off the battery of my MacBook when it run.

...why I do this ? I always turn off my MacBook "normaly", but in this case, I was surprise by the "automatic run" of the laptop, without I activate any command in the battery menu 😮 !!! Plus, my MacBook wouldn't turn off, the keyboards did'nt respond; I just can use the trackpad to use the mouse and try to stop it !

That's why I do this, friends.

After, when I replace the battery the MacBook wouldn't run; I check the charge of the battery, 3 of 5 leds are lit.

Try to reset SMC, doesn't change anything.

When I plugg the battery charger, there's no light, and it doesn't change when I pull off the battery.

So, I need your help to go further and restart my MacBook 🙂

It's an "old" MacBook Intel, with OS X 10.5.8 (waiting for Snow Leopard delivery), 2 Go ram, 130 Mo HD...and it's my "music producer" 😍
