The fan noise in my Inspiron N5010 has been driving me crazy, so I took it apart (carefully) to inspect and clean the fan if necessary.
Upon reassembling (of course), now it won't boot up. When pressing the power button, it blinks once as does the left of the three LEDs at the bottom left of the front panel. Nothing beyond that initial single blink. I have tried with and without the battery, held the power button for 45 sec without either, nothing seems to help.
I have checked and rechecked all of the ribbon cable connectors. The black "clamp" on the one from the power switch came off but I was able to reinstall it. QUESTION: the ribbon goes UNDERNEATH the four prongs, correct? It won't stay put unless installed that way.
After the fact I noticed that the mini-screwdriver I used to remove the various parts was magnetized. Not ideal, but would this cause such a problem?
Appreciate any guidance.
