Mac Pro :: Control Cpu Speed And Voltage Under Osx?
Feb 21, 2008i am new to mac and coming from linux. got my mac pro about 3 weeks ago and i am wondering if there is something similar to powernowd or cpufreqd under osx to control the cpu speed and voltage of the 8 core monster. i mean there must be some power saving features in osx for the macbook series i guess and i want to know if there is something similar for the pro series.i am not sure if i better asked this questions in the osx forum but its somehow mac pro related. so are there any power saving features cpu speed or vcore related for the desktop mac series in osx right now?or is it maybe not supported yet because the hardware is so new?
View 5 Replies View RelatedMacBook Pro :: Does Battery Run Out Stress Voltage Regulator?
Jul 20, 2010I've now seen 2 machines have a logic board failure from letting the battery run dry (which shuts the computer down). I suspect the voltage regulator based on what I've seen and reading up on what the board level repair guys are finding. My question is does letting the battery run out stress the voltage regulator and is this situation to be avoided at all cost?

View 2 Replies View RelatedMacBook Pro :: Clinging Sound From System / Low Voltage Current When Touch Aluminum Unibody
Oct 6, 2010I finally put my hands on a brand new MacBook Pro 15" (base model) with Hi-Def Glossy Screen...I'm playing with it since a couple of days and I wonder if it is somehow defective...I've already passed through the following thread but I haven't found the answers I'm looking for....URL
I've also searched trough the forum, found a couple of related threads but no conclusive answers were given, so that's why I'm posting my doubts and asking for you to comment or give your personal experiences or advices...
1) Power dazzle (sorry I don't know how to better express it)
When I plug the cable to recharge the battery and the battery gets finally completely recharged, I feel a sort of low voltage through my hands when I touch the aluminum unibody... I was used to feel the same thing on the touchpad of my former pc when its logic board started to break... (that's why I'm so worried about this potential issue)Is it normal? Do you experience the same thing? Is it to notify the battery is fully charged? I don't think so: a pop-up message would be much more effective...
2) Clinging sound
When I use the MBP in a quiet room, I often hear a clinging sound from the touchpad... I suspect it is the HDD's head that moves to perform an operation... or is it something completely different? In any case, it is very annoying: when I hear it, I immediately start to search myself for any tab of a zipper that may produce it...Again, is it normal? Does your MBP is the same? Does it annoy you? Am I simply paranoid? Did you do something to effectively reduce it (SSD)?
3) Battery life
I tried to calibrate the battery properly, nevertheless I didn't experienced the advertized battery life... I think it depends on the fact I have the Hi-Def screen that is more power demanding than the default one...
Is this the effective reason? How long does your battery last? (I cannot post my value because I just discovered the option to show time besides battery icon...) Any suggestion to make the battery last longer? (I already use cable rather than wi-fi and Intel graphic card rather than Nvidia one)
4) If I move my finger tips on the bottom of the unibody enclosure, I can feel a small step between the enclosure and the cover (something less than 1/3 of a mm) in the area below the touchpad that progressively disappear toward the hinge area...
Does your cover integrate seamlessly into your unibody enclosure or not?Is it an indication of some sort of refurbished intervention or is it normal this way? How can I understand if it is a refurbished MBP or a brand new one? (It's been bought by my university, so I don't know exactly what has been ordered... there is something I have to look for to understand the case? A particular notice, booklet or something like that?)
