MacBook Air :: Fans Does Not Work And Stays At 0 RPM
Apr 24, 2008
My MBA is 1.6/80. The fan does not work suddenly and stays at 0 rpm (istat pro, smcfancontrol), no matter how many times I've restarted it. I've been using coolbook to adjust voltage and smcfancontrol to adjust the max fan speed, but do not think it is really the culprit as there are other reported cases online. I've run the hardware test and there was an error shown: "4MOT/1/40000002:Exhaust-0". Also it shows in the activity monitor the UserEventAgent(117) is not responding.
The weather in the UK now is around 13 and the temp of my MBA is hovering between 62-70 C (istat-pro) in-door all the time, just surfing the net! I've been loving this machine up till the moment the fan stopped. It is really frustrating as this is my first intel mac, and the fact that i'm relying on it for preparing notes for the approaching exams makes it even worse. I really doubt its reliability at the moment.

I'm nervous to install the Firmware update 1.3. As I've heard from a lot of people the update has crashed their mac. I know it has to do with the fans and temp. My Mac book pro is running at 135 F at 2000rpm is this ok? Is it too overheated. Should I install the firmware I'm so nervous to install it just in case it breaks. Here's the rest of my specs...

the other day i wake up and open my macbook pro and immediately heard the fan making noises ive never heard it make before. i checked istat pro. the fans were going at 2000rpm. this is when i started to get concerned since i would never hear the fans at that speed before. the difference was day and night. it sounds like the one or both of the fans are hitting something. i always hear the noise when i start up or wake up from sleep and after a while (30 minutes to an hour) it usually goes away but has come back once without me turning off or putting the computer to sleep. its a refurbished less than a little more than a month ago. im hoping its just some dirt that made it through keyboard and will eventually go away because i dont want to send my machine in to get manhandled by apple repair. has anyone had something like this happen before?

My CPU fans for proc.A are near-constantly capped at 300rpm(system minimum), no matter how damn fast the B-fans spin to compensate.I have: Kept it clean inside. Kept CPU settings on Highest, as usual, but tried Reduced/Auto Repaired permissions Reset the PRAM Reset the PMU Booted into single-user mode Reinstalled Leopard
Obtained & ran Service Diagnostic CD and passed all tests Re-calibrated the CPU's only to notice the speeds now hover around 400rpm now What more can I possibly try? I don't believe a re-seating of CPU's is in order. They work great. All my fans & temperature sensors passed their diagnostics tests, too.I am very irritated by the noise of 2/4 fans overcompensating and getting very loud, from 2000rm-4000rpm, and hey, my Mac is screwed up, and I really need to fix this.

I have an imac 7,1 - intel core 2 duo, 2,4GHz, that is 20" from mid 2007 with an HARD DISC: Western digital : WD3200AAJS - (320GB) that died.so I bought a NEW HDD: Western digital: WD10EARX - (1TB): Caviar green series I changed step by step the HDD and reconnected everything and all went well, until I re-started the iMac. After approx. 2-3 min the HDD Fan began to increase in speed and since then I have tried everything that I found on the net and nothing worked to slow down the fans.
That is the external temp sensor is set in the same way as it was on the old HDD. I reset the SMC and the PRAM several times, actually oppened and checked all cable conections three times. I installed the SMC fan control - no difference, the HDD fan control demo version - no difference. THUS the problem is that the FANS do not stop working as if the comp is on fire.

iMac (20-inch Mid 2007)

I'm using my Itunes on my OS X (Late 2008 Macbook pro 15 inch) and everything is fine and then I am done. I click restart. Everything happens normally it shuts down and so forth but doesn't restart and just stays off. I click the button to turn my mac on again and I hear that start up noise but 1 second later I hear the shut down noise that it makes. And the little button that u click to open your mac when its shut lights up barely and then turns off.
I have no idea what might have caused this and have tried a couple of things like taking out the battery and the adapter and clicking the turn off button for 5 seconds. But no dice. My battery is at full power so it can't be that it just needs to recharge. I really need to use my laptop for work Monday and its Saturday...

Whenever I close the lid to my MacBook it'll go to sleep by turning off the harddisk and the light is blinking. But when I go to pick it up or even move it the Superdrive makes a noise as if its searching for a disk and the apple on the lid/monitor blinks on and off. Basically the computer never really stays in sleep mode.

Im really sorry if this is a silly question. I was playing football manager, then had to dash off somewhere for 15 mins, by the time i got back the screen was black, i just assumed it was on standby, i pressed space bar to carry on playing and NOTHING happened.. i pressed the on|off button and nothing happened.. i pressed and held the button to switch it off.. nothing happened..
It is still running now, but nothing is activating it, i pressed the caps lock button to see if the keyboard was operating and it didnt light up as normal.Im just letting the battery drain on it to see if it does anything on the reboot.. i dont know what else to do.. please advise!!!I only purchased it on Fri.. so its 2 days old i really hope it isnt broken already, there must be a simple answer for this? I look forward to reading any advice,

I've set my energy saver preferences to put the display to sleep after 10 mins and the computer to sleep after 15 minutes of inactivity. The display sleeps but the computer always stays on, whether on battery or A/C. What's the problem here?

I have an MBP about 2 yrs. old. This morning when booting up, the computer made the chime sound and appeared to turn on but the screen stayed completely dark. I tilted it around and tried to see if the backlight was just dead, but there appears to be absolutely nothing on the screen. Furthermore, the little light that normally pulses while the computer is sleeping is on, though not pulsing, anyone know what's going on?

Loaded pics up for the 1st time from my 7d into Aperture 1.5 and left my computer on, woke up and it wouldn't come out of sleep. I did a hard shutdown holding down the power button and the screen just stays black and I never hear the chime, light on power button is solid white. Since I'm on vacation with my wife and infant daughter I don't have time to mess around troubleshooting but see it may be a failed logic board? Do they just fail randomly or what? My aunt that I'm staying with turned off a surge protector a light was plugged into, I was using her power charger for her MacBook Pro and only this morning found out it was plugged directly into the outlet below the surge protector was on that she flipped off.
Could that have created a surge on the other plug or something? She does this all the time with her MacBook Pro plugged in and its never created a problem, I'm writing this post from her computer right now! (Only brought the Mac out because my iPad wouldn't load the photos for some reason, don't know if it has something to do with the HD video or because I also had photos from my Canon 50d on there or if that has something to do with my Mac's problem?) I've attempted an SMC restart and it does the same thing? I'm now extremely stressed thinking I may have lost all my pics that I haven't backed up in months of my infant daughter. When I start it up I hear an initial sound of a hardrive spin or fan but then its basically silent.

I can hear the chime going off, but the display turns on you cannot see through naked eye, you have flash light onto to the screen to see very little, can you tell me why this is happening and how to fix this issue. Secondly, can you tell me how to fix this issue, my keyboard and trackpad doesn't work. Is it the problem of flex cable of both the keyboard and trackpad or is the related to software

I've changed the icon for my "documents" folder, but the change did not take effect on my "documents" icon in my dock. I removed it from the dock, and dragged the "documents" folder with the new icon into the dock, but it just shows a generic blue folder. I logged off, and logged back in, but I still only see a generic blue folder.

I noticed after the Java update the other day that my Air no longer revs up to 6200RPM when using MLB Gameday. The temperature now stays cool and the fans at ~2500RPM.

My 2007 MacBook is starting up and making all the right noises but the screen stays black - looking on different forums it seems likely it is either the back light or the inverter that need fixing but in the meantime there is some things on there I need - I have an IMac as well and I have tried to connect the too so that I can view the macbook on the imac - I used a firewire cable and held down the t key on the macbook (but obviously couldn't see if it had worked) I then turned on the Imac and held the option key down but it only give me the IMac HD to start from and not the Macbook

I have been trying to upgrade to OS X Mavericks. I went to the AppStore searched it, it came up and I clicked download. Then it asked for my apple id which i put in as usual, then it says downloading and the mavericks icon goes down in my dock bar. The problem is I have waited five hours and the progress bar hasn't moved at all. I don't have anything open but the mavericks downloader on my computer and I have tried restarting and pausing the download. A total of 20 hours for waiting for it to download. I have also typed codes into terminal, but this did not work.

I have a 2008 Macbook and when the power is plugged in, the light is green, however my battery will not charge, and it even says at the top "battery is not charging" If I remove the power cord from the computer it will still run off the remaining % of the battery, but If I reconnect the cord it lights up green and I never see the amber charging color. I traded out my battery as well as a different cord and still the same results. My battery will charge up on a friends macbook, but not on my own. I want to take it to the apple store but I'm at school and there is no store near me.
