Why won't my MacBook boot up.

I have a 15 inch non unibody MacBook pro that won’t turn on. It originally turned on when I got it last year no problem. Then it started to take longer and before harder to turn it on. I recently took it out of storage to turn it on and can’t get anything out of it. Last time i had to do something with the ram when it was plugged in to turn it in. Is it the pram battery?

Yes its possible your pram battery failed, also make sure your ram you put in was compatible( 667mhz ddr2 pc 5300 or 667 MHz DDR2 SDRAM). Try a pram reset or smc to see if it comes back on.

Hope it works,
