Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off.

From a cold startup my Macbook pro 13 fan runs continuously at high speed.
View 1 Replies View RelatedI purchased my PowerMac G5 in 2003 and no problems till now. My problem is that on startup, the display first shows gray screen with a globe in a white box flashing in the center of the screen. This continues for about 90 seconds --- then the globe in box icon changes to a small file folder icon with alternating face/question mark flashing in the file folder. At about the same time, the fan speeds up dramatically. The fan continues to run at this high speed for about 90 additional seconds, then the fan returns to normal speed, and the startup continues normally to the blue screen. Once startup is complete, computer runs okay. The whole process takes about 4 minutes.

I purchased a used ibook from owc in January and have had it back to them twice for repairs. Lately, it stopped booting up again and they told me to use [URL] to take the mobo out and ship it to Arizona to have the solder refloated. I did and got it back, put it together and it would boot up, only to run for 15 minutes and shut down. Thinking I missed something, I dissasembled it today and reassembled it. Now it turns on with a blank screen, the fan runs on high, and it will go no further. I tried to reset the power manager, reset the p-ram, the hard drive is only a few months old and my brain is getting fried with frustration.

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.)
View 1 Replies View RelatedMacBook Pro 2.16 Intel Core2Duo with 2 GB 667MHz SDRAM runs very quietly when being used. When left with lid closed overnight but still logged in, each AM the the fan is running loudly at high speed and the case is hot. As soon as I open it and it starts up, the fan quiets down and the case is cool in a few minutes. The temps range (when open and quiet) from 90-125 F for various components and the fan speeds are about 2000 RPM. Why should it run hot when closed and asleep.

I'm using iStat and it says that my CPU runs at temps around high 70s, low 80 degrees Celsius for about 10-15 minutes at a time (also says the same for Airport card). It usually takes a while for it to cool down. I always place my laptop on flat surfaces. It does this even during light internet surfing minus flash or any other multimedia...now WITH multimedia use, it reaches the 80s no problem and I just quit the process cuz I don't want my laptop to explode one day.
I just wanted to know if this was average and what temps everyone else is usually running at?
I'm afraid that if it runs at these high of temps for a long time each time like that, then it may do some damage somewhere...
Just wondering if anyone has ever encountered this or if any experts out there know of the issue.I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.

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"?
View 6 Replies View RelatedI have an early 2008 Black MacBook with 4GB of RAM and the stock 160GB hard drive. Sometimes, when I have only Mail and Safari open and am just browsing emails, the fan starts to run full speed, and the internal temperature reaches 180. This often happens when the Mac is actually idle and only displaying the screen saver! The room I'm in is rarely over 75 when this occurs. I don't really have any intensive login services, just a GMail notifier and things like Suitcase and iTunes Manager.

View 1 Replies View Related purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?
Fan runs on high all the time except when put to sleep or off? Vents are clear no blockage.

I have a G5 (Power PC, g5, Dual 1.8 GHZ with 1.25 GB SDRAM, and Mac OS X 10.4.10-phew!) and I recently: added more USB ports using a PCI card, and purchased a non-Apple 22" widescreen display.
Prior to adding USB ports, I was using a hub that ran off its own power source, and used a Samsung 19" monitor.
My situation now: everything starts up fine, but ultimately the fan will kick in at SUPER HIGH and won't stop. I can put my Mac to sleep--which stops the fan noise--but then it won't wake up.
I have run the Apple Hardware test and everything checks out OK. I've also reset the SMU according to directions from this forum; AND I've vacuumed out all the dust bunnies.
The fan runs so loud and so high it sounds like it's an airplane that's about to take off.
Short of bringing in my Mac to a technician, can you recommend anything? My Mac has been glitch free up until now.

my new white macbook runs slower on battery that when it is plugged in. The most noticeable thing is that the applications folder loads slower and is laggy to scroll in.
Unchecking put harddrive to sleep when possible did not fix the problem.
Any ideas or is it supposed to run slower to save battery?
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.
View 1 Replies View RelatedLately my MacBook is making a lot of noise. I was at school working in Google Docs when suddenly a lot of noise came out of my MacBook and I think it's the fans.
When I for example watch a YouTube video the noise starts and I'v never had that before. Also when I run my Minecraft server and Minecraft at the same time it starts spinning at 6175 RPM. I know those are resource heavy tasks but I've never had that before.
I installed smcFan to monitor my fans and the degrees (C°) goes from 49° to 91° when I open Minecraft. Early 2011 MacBook 15" on Lion 10.7.3

View 3 Replies View RelatedSo my Macbook Pro has been working wonderfully, until recently when it runs out of battery it goes into sleep mode but when I plug in the power cord it does not do the restoring from how it was before (i don't know what its called, but its when the screen goes grey and the white bars go across until i can get back in) it does not show me anything so I have to press the power button and even then it does not show me that screen it just reboots (i don't hold it in but just press it normally like when booting it up) Then when it is booted the date and time are reset and the Wi-fi does not work. I have to reset the clock and it then works fine.

As stated on subject, the fan in my PBG4 runs at max speed from the laptop starts. I have tried to reset NVRAM, PRAM, PMU, but no luck. The laptop is not hot at all.
View 2 Replies View RelatedI 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?

View 7 Replies View RelatedOur iMac is 18 months old and three times in the last few months the fan has switched on at full speed as soon as I press the power button. If I disconnect the computer from the power source and turn it upside down before reconnecting and starting it up, the fan will then work normally. Has anyone else had this problem? I guess the answer is to take it to a service centre, but I thought I would see if there is a simple resolution to the problem first.

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.
