The bearing is not locked. Thanks for looking at the video (a lot of people don't do that!). So I appreciate your advice and assistance. It was good to watch those two videos becasue I didn't know if my fan, when spun manually, was normal or not. Mine only spins about four or five turns when I give it a whirl with my finger, so, I'm pretty sure the lubrication is gone. Even though it's working at the moment, I expect it to stop working soon, so, I plan on taking it apart and lubing it. The one video said lube only lasts a month, which is too little time for so much effort (disassembly and reassembly being a PITA). So, I'm looking for what lubricant to use. This article suggests sewing machine oil: http://lifehacker.com/5761236/temporarily-fix-dying-laptop-fans-by-lubricating-them The comments in that article suggest white lithium grease. |

Thanks for the drawing. These fans are interesting as they're super simple. I'm pretty sure my fan lost its lubrication, which means I pretty much need to lube it manually, which means I need to disassemble more. Nobody says you can permanently fix a dying fan, but, most say you can get some more life out of it, or, at least use it while a new fan is on order. Plus, if I disassemble it, I might be able to find a part number for the fan itself, since the heat sink is what's costing so much money ($75) and nothing goes wrong with a heat sink. Looking up the lubricants to use, I found this, which resurrects the age-old question of using a thin oil such as sewing machine oil versus a thin grease such as a dab of white lithium grease. http://superuser.com/questions/1007968/what-lubricants-can-be-safely-added-to-a-laptop-fan The comments in that article say that laptop fans are typically designed to work without lubricant, which I find odd. |

She said it sounded like a sharp crack, like a "bottle breaking". Just to give back to the team with a current update ........ http://i.cubeupload.com/YGQ9cM.jpg 1. I shipped the boards off to "Circuit Board Medics" at 800-547-2049 2. They told me over the phone my F28 (aka F11) is almost certainly a blown MMU. 3. They didn't know it at the time, but my MMU has multiple charcoal spots! 4. So, they're right. http://i.cubeupload.com/k1m0mV.jpg 5. Nonetheless, I sent them *both* the MMU and the CCU. 6. This is so that they can test them both (just in case). http://i.cubeupload.com/RfF0Bv.jpg 7. Current charges are $130 + $15 Fed Ex out + $15 shipping & handling back. 8. That's $160 for them to rebuild the MMU, with a 1-year warranty. http://i.cubeupload.com/k7Hwkl.jpg 9. Other options were to buy a new ($200 to $300) or used ($100 to $200) MMU. 10. Or a new washing machine ($600 to $800). http://i.cubeupload.com/ErHVuc.jpg |
