Doesn't turn on after disassembling for dust cleaning
It is not the first time I disassemble a computer. I have done it many times with my MacBook Pro.
But this time, I have done it for the first time on a Macbook A1181. I followed this guide to access the fan: MacBook Core Duo Fan Replacement
After reassembling the computer doesn't respond when I press the switch... :-(
I have checked the upper case cable (step 12) but it looks fine.
What should I do?
