He is 14 so keep that in mind when he gives his expert opinion.

Does that mean my opinion isn't valued because i'm 17? Although what CATS said was bollocks, see my previous post.

Jest because I'm 14 (15 on the 30th) I can't help people with problems on there Mac or explain what I'm talking about (even if they don't get it)? This is the very reason I left the lounge...

I don't want to share my birthday!

I just ran the upgrade earlier today. My MB is running a bit cooler according to CoreDuoTemp, so that's nice, but I actually just experienced my first random shutdown now. I had been working on it, closed it to put it to sleep, brought it home in its case per usual, and when I opened it up, it was off. Upon restart, I got a message saying something like it had "restarted" due to a sudden OS shutdown. I thought this update was supposed to help with these sorts of problems, not cause them... anyone else having trouble? I had noticed recently that when my battery starts running low, my MB will shut off sometimes with no warning, but I figured that to be a battery-related issue. This time it was fully charged, so that shouldn't have played into it.

eightbit · Oct 29, 2006, 06:14 PM

that's a different problem than the random shutdown. you have to wait for the computer to completely turn off before shutting the lid. if you don't, it'll get stuck in this quasi-sleep mode, things will get hot, and you'll not be able to turn on the system correctly the next time.

edit: just realized that you said you closed it to put it to sleep. that shouldn't have caused that problem. are you sure you didn't try to turn it off first?

jesrae · Oct 29, 2006, 06:26 PM

Very sure. I very rarely shut down my computer and never in that sort of situation. I just close it. It definitely was asleep or at least should have been, and then when I started it back up gave me a message that it had shut down due to an error.

Edit: It was hot to the touch when I took it out of the case, so something screwy might have been going on, but by then it was off.

yusung · Oct 29, 2006, 06:48 PM

It takes the MacBook slightly longer to go to sleep than earlier machines since it is writing the memory to disk (the "safe sleep"). You can see this by noting the delay between closing the lid and the pulsating light.

However, if you move the MacBook during this time period (at least enough to set off the sudden motion sensor) a Kernal Panic may occur. The end result will be something similar to what you are describing.

That might be a kernel panic. It might be the firmware acting strangely in your system.

acoustix · 11:32 PM

I have been wondering about one thing regarding this update and the shutdown problem; if the problem was strictly a hardware/heatsink issue (and hence the suspicions about this firmware quick fix), then why did some people only begin to become effected after installing 10.4.8 or after installing the first firmware update, in effect "triggering" it with software/firmware? Is it also possible that certain overheating problems could be re-distributed/rerouted/eliminated with a firmware fix? Maybe people (software engineers) who actually know something about the topic could comment....

It doesn't... just had a Random Shutdown.

BUT, it does seem to lessen the frequency. For the last almost 3 days, I've been sleeping and waking my computer with high frequency. In the past, I rarely survive waking up once, let alone multiple times. So, I almost thought it was solved.

Then I was just sitting here trying to book a flight... and now I need to make another visit to the Apple Store and give them a second try at the hardware fix.

Very disappointing!

No but it helps put some of your gobbledygook into perspective.

I thought I just saw you in the lounge?

Tarcat · Oct 30, 2006, 04:36 PM

I have yet to have the problem since upgrading.

Powerbook lover · Oct 30, 2006, 07:43 PM

I sent my mac in to get it repaired for the RSS and they only updated the firmware. I still haven't experience the RSS but my fan is now constantly on. The battery charge only last an hour because of this. Please help!

frankthetank966 · Oct 30, 2006, 07:47 PM

Increasing the volume (which is unlikely because you cant increase volume of speakers with an update it has to do with wiring), cooling down the comp. and lowering fan noise are all great things. But the one I really care about is it being able to "prevent" unexpected shutdowns. If it does that I will be very happy.

Powerbook lover · Oct 30, 2006, 08:03 PM

Okay. I think I might have fixed the fan speed issue by resetting the PRAM.

volume has to do with wiring? It think it depends on the amount of power and the maximum volume setting which can be adjusted with software.

the speakers are not going to get better do to a firmware update. they would onlygetbetter if they were replaced.

Sorry but mine are MUCH louder after this update so someone must have snuck in my house and replaced them.

Run this: CoolBook 1.0 - MacUpdate

If you want, this will end all your heat problems and let your MacBook get a longer life.

chadseld · Nov 1, 2006, 06:56 PM

I'm just bummed that the update seems to have turned off speed-step. My MB runs about 5C hotter at idle than before. I don't run on battery power much, but I expect there is a small reduction in battery life associated with the change. I wonder if there will be a third firmware update which turns speed-step back on?

CoreDuoTemp tells me that it still works on mine. Are you using that?

acoustix · Nov 2, 2006, 12:55 AM

I'm done with CoreDuoTemp as everytime I start up it says: "Speedit not installed-please open Speedit installer"-it has never given accurate temps for longer than two minutes anyways.
"Fan Control" gives the proper temperature, along wth the fan access.

Install Speedit, it worked for me just fine.

I have installed Speedit; many times. It won't stay installed and keeps asking me to re-install it every time I reboot. I read somewhere on-line that this was a known issue. Also like I said the readings have never been close to accurate, always saying "19C", etc.

Yeah, using core duo temp, it reports that my CPU never drops under 2GHz for any reason. I don't suppose it's a huge deal, but it is still a bit of a bummer.

Dark Helmet · Nov 2, 2006, 01:28 PM

iStat nano works great for temperature readings.

hookem2oo7 · Nov 2, 2006, 01:31 PM

iStat nano and pro don't see any temp sensors in my macbook

You have to install Speedit first. I was puzzled by that for a while.

After this upgrade, my Word opens almost as fast as universal apps. Photoshop and Illustrator are a little faster, but still pretty doggy. But after I was done playing a bit of Quake 4, both of my CPUs were at 118 F, right now, it is at 59 F.

I think the speed increase is either your imagination or due to some other factor. Also, there is only one temperature sensor.

unfortunately, the speedit site is down for maintenance and I can't find a mirror anywhere

scoot · Nov 2, 2006, 09:58 PM

I installed the update shortly after it appeared. I had been experiencing random shutdowns intermittently since the previous firmware update.

So far, it's been up for 5+ days, with pretty heavy use (which I'd been avoiding) and frequent sleep/wake cycles. Over the last day or so, temps have been at the 80C level, with no shutdown, fans running.

I forgot *why* it was running hot. I'd started dual "yes >/dev/null" processes 30 hours ago. They're still running. Whoops.

It was the restart...lol

Yeah thanks, I'm stupid, I know.
