Fans bumping not spinning not powering on
I replace the lower case, everything went smooth, but now when I hooked up the battery and hit power the fans just bump and do nothing... I hook up the power supply and the fans bump constantly. I get a green light on the power supply, the battery is at 3 lights but won't charge... I replaced the I/O board and the same issue. I reset the SMC and tested the jumper on the logic board for the power bypass... fans respond same. Is this a logic board problem now? Any help is appreciated.
Hey Ralph thanks for the idea... stripped the computer down again and checked the fram rib and double checked the screws as you suggested... got all the right one in the right place and not ripped down tight, didn't see any dents in the lower case to show the screws touching. Same issue persists.
Can't see it moving in a pic, but that green light is with a battery with only 3 lights. Thanks again.

Sorry for the delay in my answer. In my case I had done a full lower case replacement. My issue was bad ribbon cables, the ones connecting the I/O board to the logic board was not sitting flush. fixed that issue but the right fan still didn't spin, so I unhooked the DVD player and then the right fan spun and the machine booted up. If you are getting a green light on your charger with your battery dead then power is not getting past the I/O board. Wondering is something came lose when you pulled the top case off.
