MacBook Pro :: Keyboard Backlight Off And Fans Run At High Speed
Jun 20, 2014
My Early 2008 MacBookPro 2.40 ghz 4 gb Ram OSX Mavericks machine's keyboard backlight off and fans run at high speed; it seems an exact smc resetting problem.
So i tried the 2 ways of SMC restting procedure; both battery you can move and not, but nothings changed on the situation..
On the way for removable battery; nothing changed but on the way for umremovable battery way; keyboard backlight flashes and gone, but fans are at high speed not changed. So nothing changed.

Does it hurt the computer... If the computer is doing something (watching flash, playing a game) that turns on the fan full speed;Does this hurt the computer? There are a few games I like to play and they turn on the fan at full speed (computer gets hot too, on the bottom.)

I have a late 2007 macbook pro and recently the fans have been going at extremely high speeds without the MBP being hot at all. I have SMCFanControl and iStat Pro and both of them said my MBP's temperature was around 55C though the fans were going between 4000 and 6000 RPM, I also checked the activity monitor for high CPU usage but nothing high there. I turned my MBP off for 5 minutes with a fan blowing on it just incase it was hot but when I turned it back on the fans immediately jumped back up to 6000 RPM. They're back to normal now but I assume it will happen again. Anyone know what's wrong?

My Macbook Pro (13", early 2011, Core i5 @ 2.3) started to behave weird, its fan (only the exhaust one, since it's a 13" Macbook Pro with the Intel HD integrated graphics) is running at top speed (6200-6208 rpms) with no reason at all. No system processes consuming high CPU, just idling.There's a twist to this issue, though. It only does it when I open the lid more than 90 degrees. If I get it back the fan returns to normal functioning.What I did:checked the temperature sensor values, they are finechecked for crazy background tasks, there are none, CPU usage is at max 7%it does the same thing even in safe modereset PRAMreset SMCreinstalled OS X (Lion). Updated to 10.7.4searched every discussion I could find on this matter.
The difference between this issue and others I encountered along the way is the lid opening thing.Does anyone know if getting the lid past the 90 degree mark triggers anything?The other theory I have is that there's some dust blocking the intake and when the lid is opened wide, the air is somewhat obstructed by the bottom of it.

The other night, my MacBook Pro's fans started running at high speed when the computer was asleep. Loud enough to wake me up. And this just kept on going until I finally decided to turn the computer off. Is this normal? Is this anything to worry about?

I only started noticing my fan running a bit on the fast side this evening after installing the new Safari 4.0.5 update. I looked at iStat Menus for temp and CPU. And I was seeing about 190 degrees F for CPU temp with lid closed running ext display. Also there was a constant usage of the cpu (about 30% User and 20% System). There's not one particular process I can see in Activity Monitor that acting out of the ordinary and using a lot of CPU. Just stuff like coreservicesd, WindowServer, launchd that are shuffling around and using about 1-4% of CPU.I ran repair disk permissions and verify disk. Verify Disk found errors and said I need to repair my Macintosh HD, which I have now done successfully.

My iMac (intel core duo) after a hard drive replacement seems to be running the fans at a high rate of speed. Usually just a few minuets after startup. Before the upgrade they were almost silent and now they are very noticeable. I need to get taken care of or just a result of installing a larget hard drive?Â

I don't have any other flaws except for this. Why could this be?

Both of my fans are running at the max 6200 RPM and have been for well over an hour. My CPU is over 65% idle, and none of my processes are over 20%. My HD Temp is 38 degrees and my CPU temp is 72 degrees. I don't think my fans should be running this high considering the computer is doing so little work.

Last summer my MBP 2.3 GHz C2D was heating up so much, you barely could touch it. So I decided to give it a little hardware checkup. Finding the fans completely stuffed with dust
But after a while i recognized that the fans went on high rpms (around 6000) already at startup and did not lessen anymore. I do not have any high capacity processes running and the temperatures are not just not warm buth rather chilly, so no need for high fan speed. Now I want to solve this problem as well but seemingly nothing will work.

I am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?

It's the 2008 model MacBook Pro with the 9600m gt 512 card.
So, I just noticed that when I have my MacBook Pro in High Performance mode it emits an high pitched noise when the fans are running around 6.2k RPM and the CPU and GPU is around 63c. The noise follows the speed of fans, and at idle the noise is gone.
I have uploaded a video of it on youtube here: http://www.youtube.com/watch?v=HioRgTNpNRA

I've got this weird problem with my late 07 SR 17'' MBP, after I plug in the Magsafe charger the fans start spining and in like 3 minutes they reach 6000 rpm (both of them) and stay that way until it's finishing the charge. I did the same exact tasks with my laptop charged and plugged in, and the fans stay around 2000 rpm, as opposed to when it's charging staying at full speed.

I was just wondering if it's okay to run the MacBook with the max fan speed (6200RPM) at all times? It's really hot nowadays and my MacBook runs at about 60 degrees Celsius idle. If I run a few CPU intensive apps, the temperature usually rises to 70-80 degrees. This is with the fan running at max speed. So what I want to ask is, will it be okay to keep the fans running at max speed at all times? I'm going to get a notebook cooler soon so that should help with lowering the temperatures a little lower.

I've bought a brand new MPB 15'' about 2 days ago.Â
Every time I put it in sleep mode (by closing lid, or manually choose Sleep from menu) it goes to sleep (I check it by front indicator), but FANS STARTING TO ROTATE AT MAX SPEED (Sorry for CAPS)Â
I've already reseted the PRAM, reseted the SMC. Turn off any sharing. But that did not help.

I have a Macbook Pro (Newest gen.) and sometimes the keyboard backlight wont turn on. I suspect it to happen when I have had the Macbook on standby, but I don't know for sure if that is what does it.
Then i press the backlight-adjust buttons on the keyboard, this OSD-symbol turns up: http://peecee.dk/uploads/122010/Scre..._big_thumb.png

In regards to a 2010 13" macbook pro's illuminated keyboard.
1.) Is there a way you can make the keyboard's backlight become brighter in low light situations?
2.) Is there a way for the backlit keyboard to turn off in lit rooms and turn on in dark rooms?
For some reason the backlit keyboard becomes dimmer in low light situations. I'm finding it really irritating. I have a feeling this is the way it is suppose to be so that the keyboard doesn't blind you. Any programs to hack the light sensor?

I have tried a SMC reset 3 times, I have tried deleted the plist file and I have tried the finger over the isight lens and nothing is working. Â
The buttons work fine and it increases and decreases on the screen, it is just there is NO LIGHT whatsoever! Â
I don't know what else to do and don't want to send my laptop off to get fixed if it is just a simple thing I can do.Â

I was surfing the web when my keyboard backlight started to fade on and offat somewhat regular intervals. After about a mintue or two of this, the backlight just went off all together. Now, when I press the F5 or F6 key to brighten or dim the keyboard, the keyboard backlight does not respond. The usual screen pop-up that shows how bright or dim the keys are no longer increases or decreases but shows the symbol of O with a slash through (like the no smoking symbol).

My back up 1.6 ghz G5 power mac is misbehaving. I moved the system to another room and when I went to boot up, the only response I got was the fans running at normal speed - and then they started to slowly creep up to a very high speed. No hard drive activity, no monitor activity. I swapped out the memory for the original factory mem - same problem - reset the switch... nothing.

I have this Power Mac G5 and every now and then it'll freeze up, the fans will go full blast, and the screen will go black. It's not even when I put a heavy load on it.I usually just hold the power button down and do a hard shut down. Does anyone know why this G5 keeps doing this? Should I re-seat the ram and GPU?

Whenever i open an application both of the fans go to 6000+ rpm in a couple minutes give or take.Strangely web browsing doesn't cause this speed but if a youtube video is played it gets up there fast.Applications such as quicktime and logic gets up there no matter what is played.I have fan control and smcfancontrol, 40GB free, software updated, tried the reset thing (turn off, hold power button, boot), cleared printing operations.The only thing smcfancontrol does for me is it slows down the fans quicker whenever i close all my applications.
