MacBook Pro :: Is It True That Sleep Consume Less Power Than Boot?
May 21, 2012
I have 3 questions here to ask:
1. Some say that sleep consume less power than boot, but some say it isn't. Which is true? and how it can be?
2. Is it true that charging your macbook pro until 100% then unplug it will make cycle count go faster than using AC power all day and ONLY using battery when we couldn't find AC outlet will make it slower?
3. i found that some macbook user leave their macbook charged all the time and some macbook user prefer use battery all the time. Which way is better?

When downloading via wireless network at a high speed, my PB 12" will consume a lot of CPU power. For instance, 1MB/s, almost 90% CPU.

I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.Unfortunately my cats like to touch the keyboard, thus waking up my Mac.Is it possible to wake the mac only by pressing the power button?

My 2011 macbook pro does not go into sleep mode with the power cord on. The sleep light goes on, but does not go into "pulse" mode and the fans continue to run as well as the hard disk keeps running.
The issue started a few weeks back. I have tried switching off the internet sharing and other possible settings that might hinder the MBP going into sleep mode when the power cord is in. I have even down loaded PleaseSleep but that does not seem to function either.
Seems like a minor issue, but if the MBP does not enter into sleep mode correctly I am afraid the built-up heat might damage disks, rams or screen.

I have recently discovered that my MacBook Pro (2009) with OSX Lion does not go to sleep when the power cord is connected. It does not matter if I close the lid or select sleep from the Apple menu. All that happens is that the screen is powered off, the SIL is solid and I can hear the HDD/fan. I have not changed any of my power settings recently and it has not been a problem previously. If I disconnect the power cord the MB goes to sleep as supposed to (the SIL led starts flashing).
Doing some research I have found other users with somewhat the same issues when VMWare Fusion is installed. I have done some further testing and it seems that if I disable the virtual machine's Network Adapter and quit VMWare Fusion the MB goes into sleeping mode when the lid is closed even with the power cord connected. Enabling the Network Adapter again prevents the MB to go into sleeping mode when the power cord is connected. This even applies when the VMWare application is shutted down.
My guess is that the Network Adapter somehow prevents the MB to go into sleeping mode. The workaround is of course toggling the Network Adapter on and off but the virtual machine has to be running in order to do so. Not being that familiar with network settings on a Mac is there any other way to get around the problem?

I am looking for a ups for my macpro so wanted to ask you guys how much energy the macpro consumes? I asked at the apple store and a tech guy told me the minimum a macpro (stock configuration) uses is 250watts and the maximum 350watts, can I trust these numbers?
I have the stock configuration with a geforce 8800 and added 4 more hard drives and another 8800, so I am guessing I will need an ups around 600 watts?

I ran out of hard drive space. 7 gigs left out of 85. So I wiped and reinstalled, to try to speed things up, get rid of any fragmentation, etc. I have yet to install Photoshop, and I think I may have a few .plist files left to transfer over, but right now, with ALL of my data back on it, I have 35 gigs free. That's 28 more then I did before.

I can use Carbon Copy or Superduper to clone OS X disks but having not used them will either of these programs allow me to clone from my new 13 MBP with 500GB HDD to 256 GB SSD i.e. Compress the original disk volume like Acronis True Images on Windows?

My macbook has developed a problem where when the lid is shut and the power is connected it wakes up from sleep and then goes back to sleep and repeats this process every 30-60 seconds.
What's weird is it doesn't wake from sleep and get stuck in this loop when�the lid is open and the power is connected and I select sleep from the Apple menu�when the lid is shut and the power is NOT connected and is running from the battery
I recently updated my mac to Snow Leopard and put in a new HDD and since doing so the problem has been occurring.

I added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.

So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3.
The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.
I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests.
At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower).

After talking to AppleCare, my understanding is that FileVault works by storing the entire home directory as an encrypted disk image. Fair enough, this makes sense.
However, I'm going to configure my Mac Pro with an SSD as the boot disk, and plan to move my home directory off to the non-boot disk. With FileVault enabled, this raises a couple concerns for the SSD Boot disk.

This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

Is there anyway to get the power button on the Cinema Displays (aluminum ones) to sleep a MacBook Pro? I have it set up in System Preferences to sleep the computer, but when you tap the button the Sleep, Shutdown, or Restart dialogue pops up (same one you get if you press the power button on the laptop).

My MacBook Pro 13" (Mid 2010) doesn't go to sleep, when I close the lid or when I try to activate sleep under the Apple menu. I haven't changed nothing in the system preferences. I already tried the following: unplugged all USB devices plugged and unplugged external display closed all applications (except of Finder of course) resetted all energy saving preferences deactivated bluetooth checked share options (everything is deactivated)
Then I unplugged it from the power supply and after I closed the lid, it went to sleep. Then plugged in power supply again and sleep didn't work.

Yesterday, I had some issues with my MacBook Pro, the keyboard and trackpad were unresponsive (I tried a USB Keyboard/Mouse, didn't fix the problem), it took 10+ minutes to boot up, and it refused to wake from sleep. So I did some hunting, found out if I removed the FireWire kexts, then that would solve the issue. I removed the kexts, and rebooted it, and everything works perfectly fine, with one exception. Both FireWire ports are undetected and inoperable. Would a OS reinstall fix this, or is it some deeper issue that may require a logicboard/hardware component replacement?

my old 2x2Ghz PM G5 (late2004) doesn't launch the boot sequence:
- when pushing power button, the blue led turn ON as long as I keep it pushed. If not pushed, it light off but yet the fan are running.
- no chime
- the fans turn on normally and the hard drive start a little to make noise once powered up.
- no video on display, the screen is black.
- the keyboard is not recognized anywhere I plug it.
- after a minute or two of non activity, the fans start to blow full speed (guess its a security measure for saving processor)
I ve done the reset of PMU several time (unplug the power cord then push the button at bottom of mother board)As i dont have access to keyboard, I can't start on Target mode to check if the HD is failing all.I ve removed all RAM extensions and left only one pair in slot 1 (J0), and changed the pair to avoid a faulty RAM.I only have a redlight on motherboard if I don t put back the glass panel.I ve check the voltage of the lithium battery, and yet its the original, the voltmeter says its 3,6V...

Just found this on diglloyd's site: his solution to the SSD slowdown with usage (because of our lack of TRIM support) is to:
1) clone your SSD (back-up)
2) copy a single 100%-size file on it (like copy a 73GB file onto a 80GB SSD)
3) erase that file
4) clone it back in
Is it really that simple? [URL:....]
