Apple has released new EFI firmware for the 15" and 17" MBPs.

Apparently only rev A MBPs need it. My rev B is not showing it in SU.

More information here: Apple - Support - Downloads - MacBook Pro EFI Firmware Update 1.2

Experiences? Apple claims it solves wake-from-sleep issues. Never had those, so I wouldn't know if they fixed em.

Does it really eliminate the whine?

just downloaded it and it helped with some of my issues. can someone straighten out the Rev A/B/C deal?

i thought rev A was the first batch which were in 1.83/2.0, then rev B was 2.0/2.16, and rev C is the C2D's....

I ran it last night on my RevA MBP, update went smoothly and nothing changed that I could see. Played with it for a few minutes then started BOINC. Checked this morning and BOINC was running fine and the Book was still cool, Fan Control Pref Pane works womders. Mine has never moo'd or whined, still silent except for the fans - I have them set for 3500rpm minimum and a steep ramp so the case stays cool ...

Just FYI, sometimes firmware updates do not show up in SU. You should confirm if your firmware is up to date manually.
However, I tried installing this release and it wasn't required on my rev. B.

I'm afraid it did nothing for the whine in my 1.83 Rev. A - except that now the whine heard while on battery is distinctly different from the one heard on AC. The AC whine is the high pitch squeal I'm all to acustomed to, while on battery it has more of a "high pitch rushing wind" sound - I don't now what else to call it. Not quite sure where MacNN got their information.

I have exactly the same story as Timetheus. An early 1.83GHz MBP, the new firmware just changed the sound of the whine, but did not eliminate or minimize it at all.

About the whine after firmware update: still present on my Rev A 2.0 but the frequency might be a bit lower, which makes it slightly less noticeable. But it could also be my imagination.
(Still only while on battery, never had it while on AC.)
Moderation is a fatal thing. Nothing succeeds like excess.

Rev A MBPs are the Core Duos, Rev B MBPs are the ones with C2D. There isn't a Rev C yet.

onlykaria: It's a 3rd party utility called Fan Control (Fan Control 1.1 - MacUpdate)

Personally, I prefer smcFanControl (smcFanControl 1.2.2 - MacUpdate)

To you guys with the whine issue, why don't you get the MLB changed? Apple has publicly announced that this is a problem that should be fixed.

my fan is constantly running. as well. not that it's that loud but it's really annoying, as my mbp was previously silent. i'm going to try a few things, then call apple if they dont work. i will report my findings.

for those who still have the whine: call apple or go to a store, they will easily take in the computer and change the logic board which eliminates the sound. i had to do it twice, but now my machine couldn't be quieter, at least before the firmware update.

I was having sleep issues on my MBP. It wouldn't sleep if I closed the lid, and when I did put it to sleep, it would take like literally 2 minutes to go. Then it would wake up 2 seconds later, draining the battery til I came back. After the firmware update, it's snappier and if I close the lid, it'll sleep.

However, I noticed something the other day (not sure if it was before or after the update) but when I plugged my MBP into my external monitor, it would go through this sleep/wake cycle constantly. Wake up for a minute, sleep for a minute, wake up for a minute, sleep for a minute. I have only seen it once but again, I don't remember if it was before or after the update.

My logic board was replaced shortly after purchase so I can't comment on any whining noises. I don't hear anything.

As a precaution I uninstalled FanControl prior to updating to the latest EFI firmware. A few people on the Apple discussion forum claimed that FanContol caused their firmware update process to fail on the powerup step. While I can't confirm this, it was easy enough to uninstall so I took the conservative approach. In theory I suppose FanContol might have put the system in a state the firmware update logic wasn't tested for. I also verified/repaired permissions before doing the update (again, being paranoid and conservative).

One thing I noticed is that the firmware update instructions were incorrect. After you run the firmware update and power down the computer you are supposed to press and hold the power button until (according to Apple's instructions) the power indicator light flashes. In fact on my system it was the SLEEP indicator light that flashed quickly.

Once the firmware update completed I re-installed FanControl and everything seems fine. I then also installed BootCamp 1.1.2 drivers in Windows XP with no errors.

For the record, I've never had one of Apple's software updates fail on me or give me strange results.

This can happen when you're not plugged into AC power. Closed-lid mode only works properly when the MBP is plugged into AC power.

15"RevA MBP2.0/1GB/100GB-7200rpm

MBP ran very hot, right out of the box, 2/28/06. smcFanControl was the first fix I tried. It only changes the idle speed of the fans(They always run, albeit slow if the load is low). When I found Fan Control Pref Pane, I tried it, and stuck with it. I like that I can not only change the idle speed, but the speedup ramp also. I happily trade a little noise for a cool lap.

I ran the firmware update with Fan Control installed - no probs, no noticeable changes to my MBP.

I don't understand why don't you guys with the wine problem, send your MPB to the repair center. When you call, simply reference to this knowledgebase article: MacBook Pro with noise under the keyboard
and they will replace your logisc board

that is the power indicator light...Is there another light on the MBP that I'm not seeing that indicates power?

I don't update firmware unless I need the fix they are releasing it for.

I tried that before. The caveat is that apple said that for only 15 inches. Not the 17 inchers.

Did you try taking it to the store and having the "genious" take a look at it?
