Mid 2007 MacBook won't start

The MacBook was working fine until I changed the SuperDrive, now it won't switch on. The MagSafe still shows full charge and battery shows full charge. Tried resetting SMC & PRAM to no avail.

Any help will be appreciated

Their is only one connector you have to remove when replacing optical drive that can stop the MacBook from powering on. It's the cable that drops down from the top case and plugs into the logic board. I'd whip off the top case and try reseating it.

Thanks I'll give it a go.

Reseated the top cover plug... No change.

Took it apart, dusted & vacuumed it, reassembled, now works ??!!??
