Apple says firmware update solves MacBook shutdowns

post #1 of 38
Thread Starter 
First on AI: Apple Computer on Thursday released a software update for its 13-inch Intel-based MacBooks that it claims will resolve an extremely frustrating issue where some of the notebooks would shut down randomly during use.

"The MacBook SMC Firmware Update v1.1 improves the MacBook's internal monitoring system and addresses issues with unexpected shutdowns," the Mac maker wrote in a support article on its website. "This update is recommended for all MacBook systems, including those that received warranty repair."

The Cupertino, Calif.-based company said MacBook owners may use the Software Update feature of Mac OS X or download the MacBook SMC Firmware Update v1.1 from its website.

"If your MacBook is running Mac OS X 10.4.6, you won't be able to see the SMC Update until you update to Mac OS X 10.4.8," Apple noted. "Once you have updated your system software, the SMC Update will appear as an option in Software Updates."

On the other hand, MacBooks running Mac OS X 10.4.7 will be able to download and install the SMC Update, so it is not essential that users update their system software. However, Apple always recommends updating to the latest version of the system software.

Seemingly stumped over the source of the shutdown issue until now, Apple in September began telling affected customers to contact its Apple Care support staff to arrange for their notebooks to receive hardware diagnostics and treatment.

In some instances, the company replaced the MacBook's processor heat sink and in others, the entire logic-board. However, several users who had sacrificed their relatively new notebooks to Apple's support depots for successive repairs continued to report shutdown issues.

The mounting frustration over the problem eventually came to a head earlier this month, as MacBook owners repeatedly plagued by the issue began organizing a class action lawsuit with the help of ClassAction.com.

Apple said customers who continue to experience trouble with their MacBook after applying the new firmware update, or those whose MacBook is in a state that will not allow new software installations, should contact AppleCare for further assistance.

Works for me. My problem was I had to restart 3-4 times from a cold shutdown. Never had a problem once I got going. Just restarted after letting the book cool off and WOW no problem. Knew if I waited long enough Apple would come up with something so I would't have to send it in.

You guys are kinda lucky on the not sending it in part, us MBP owners that had the whine had to send them in multiple times before Apple finally got the fix. Then we had to send it in again!

But it got fixed and that is what counts looking back.

About damn time, my gf was starting to get worried, which obviously puts pressure on me, being the one that switched her and all.

You could say that.

Twenty five years of marriage, and she STILL objects to my having a girlfriend!

Can you imagine?

I guess I should ask my daughter what she thinks.

Sure, why not? Some of my male friends also have boyfriends.

I've read in several places that the root cause of the shutdowns is due to a shorted temperature sensor. Seems the insulation for the wire running to the sensor is sometimes in contact with the processor heatsink and it melts under high temperature. If this is true then the only way this firmware fix is going to have any affect on this hardware problem is if Apple's new firmware is now ignoring the sensor if it detects a short. So instead of a shutdown, any MB experiencing this problem will now just continue to run with one sensor out of service. Better than a total unexpected shutdown I guess, but it would be better if the hardware were fixed.

I have not had problems with shutdown, but I have had other problems with my MacBook, granted they were all minor, but when I upgraded to the new firmware last night, it was like I had bought a brand new machine, the whole laptop runs better and I want to say it stays around 20-30 cooler, I never feel like the laptop gets too hot anymore.

This update was really a life saver for me. I upgraded to two gigs or ram yesterday and it helped but I still felt like something was missing and with this update I know do not have a problem running Mac OS X, Debian Linux with Parallels and Windows XP Pro with Parallels at the same time. This laptop just literally became my dream machine. The Ultimate machine in mobility and I can literally do what I want in what OS I want.

I have been on the road for the past two weeks. I started having the RSD problem about a week and a half before I left town, and I didn't want to travel without my computer, so I decided to wait until I returned. On this trip, I have been experiencing extreme problems to the point that this morning took 10 or 12 attempts plus with downtime waiting to boot my MacBook. I finally got it booted and downloaded the firmware upgrade and have been working without any problems for the last hour. fwiw, I could almost ensure that the MacBook would shutdown by starting up WinXP in Parallels, but now I have been running with it in the background.

Looks like Apple has found the fix. I had purchased my MacBook early in the summer and didn't have any problems until the 10.4.7 upgrade. Looks like Apple made have had some code that was incompatible between 10.4.7 and the earlier MacBook firmware. I hope this is the end of the problems so that I don't have to take the laptop back to the Apple Store.

I've just installed the firmware update on my Week 41 Macbook even though I have never had any problems whatsoever. I really doubt that a firmware update can solve the RSS issue though....one thing I did notice (and this has already been mentioned on the Apple Discussions forum) is that the volume level when playing audio is higher. That alone was worth the update.
post #25 of 38
I sent my Shitbook back for this problem, third repair in 4 months. Took them 5 days to run the firmware update. Definite mounting frustration. Apple guy tries to sell me Applecare. Better to just consider it a total loss if there are any problems.

my macbook has been perfect. should i still do update? people are saying there are other benifits. what are they? improved audio?
i hate to mess with success.

Other updates, or upgrades later on may require this firmware update.

Hi, new member here. I'm quite curious, as I have been given an iMac G5 with 20" screen. It's a gorgeous machine, but exhibits the random shutdown thing. Would there possibly be a fix for this, do you think? Could it be the processor sensor issue at work perhaps.

Anyway, going to try that now.

Cheers

I had no problems with my MacBook so far. Yesterday I installed the firmware update. Today I had at least four random shutdowns. What's the matter????

Hey, something different . . . its the PMU . . . Power Management Unit inside the machine. I had Applecare send us a new one; replaced on my own. Warranty covered the part, about $130 . . . if you *dig* around the Apple Support - Discussions, you will find the instructions (.pdf) on how to repace it. Good luck!

I had been having the rss problem for over 2 months. Didn't send it for repair because I didn't have a HD to back up my data...

Shutdown always occurred after sleep. Resetting the power management or whatever (by holding the power button down until the indicator flashes quickly) always fixed the problem... until the next time my MacBook went to sleep.

The firmware fixed the problem 100%.

exactly the same problem with me, but, um, to reset the pmu you have to take the battery out and hold the power button for 5-7 seconds

just trying to help, even though the problems been sloved.

Well, whatever i was doing by holding the button down until it flashed... worked. If I restarted without holding the button down, no dice. It would shut off in seconds.
