MacBook Pro :: Leave In Sleep Mode Lose About 5-8% Of The Battery?
Jan 15, 2010
I own a late 2009 MBP that I use with an external monitor as my work computer each day. At the end of the work day I generally unplug the network cable, Apple Cinema Display, and then just put it to sleep by closing the lid. Some days I use it later after I get home, others I don't. If I leave it in Sleep mode I generally lose about 5-8% of the battery by the next morning.
I'm just wondering if I'd be better off shutting it down completely each night. Any pros/cons? Battery considerations?

Lately I've noticed that whenever I put my Mac to sleep, I lose a few megabytes. At first I didn't think anything about it. Until one day I let sleep for a while I was doing something, and came back to, and saw that I had lost about 300 megabytes. While it was in sleep, no applications were running and nothing was downloading. My mac is Macbook pro, 3 years old, 120 gigabyte, 2 gb of ram, 2.33 Ghz Intel Core duo, Model Identifier: 2,2, and Serial Number:W86481HGW0H Right now it's running leopard. I'm about to upgrade to Snow Leopard. So why would it lose this hard drive space when it's in sleep mode? By the way, I bought it used one year ago. So I've only had it a year. I haven't downloaded anything from any untrustworthy websites. I only download things from trusted sources(i.e. itunes.) Please help. Right now my only solution is to keep a close eye on it, and make sure that it does not go to sleep!

I have a early 2009 17" uMBP upgraded to Snow Leopard. Prior to closing the lid to activate sleep mode, is it advisable to leave an application and/or web page in place?
I just recently, in the past week, have been doing this . . . And I was wondering if there might be any adverse effects with this practice.

I get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!
For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!

I have a MacbookPro mid 2009 and have some problems with my battery. This morning I noticed that the battery was empty through it was supposed to be in sleep mode during the night. My battery has 97 cycles and has 99% of its original capacity. What could be the cause of this problem ?

I'm going to purchase a macbook pro at some point, probably when the new announcement happens, but my question is: while the laptop is in sleep mode, does the battery turn off? Like, does it still consume energy while in sleep mode?
Probably a dumb question, but I know nothing about laptops.Never had a laptop before (currently using a imac g5 from 2006).

So my Macbook Pro has been working wonderfully, until recently when it runs out of battery it goes into sleep mode but when I plug in the power cord it does not do the restoring from how it was before (i don't know what its called, but its when the screen goes grey and the white bars go across until i can get back in) it does not show me anything so I have to press the power button and even then it does not show me that screen it just reboots (i don't hold it in but just press it normally like when booting it up) Then when it is booted the date and time are reset and the Wi-fi does not work. I have to reset the clock and it then works fine.

I use first-gen unibody 15 inch Macbook Pro. I rarely shutdown and leave it sleep. However, sleeping somehow drains battery quite much. For example, after one day of sleep, my battery goes from 100% to about 60%. My previous Santa Rosa macbook pro never did this. My current setting is sleep and hibernate. I checked it in SmartSleep.

I would like to my macbook pro to be turned off at 5% Battery power, as it doesn't turn of correctly at 0%. I'm having this issue for some years now, and want to get rid of it. Which plist needs to be changed for this? Or is there a Terminal-Command that's providing this? I don't want to buy a new battery yet, cause the one I have is quite fine still. I already reset the SMC and the Parameters. Is the battery status relevant, when resetting the SMC? Here's what has been going on so far: [URL]

When I run my macbook pros Battery down, there comes the low battery warning. After a while the system just goes down without suspending anything to my harddisk. When I restart my computer it does a normal start and after logging in I'm experiencing a lot messages due to the reset time. I correct my system-time and restart my mac and the system is back to normal.
Usually I'd say: Replace your CMOS-Battery (I know I have an EFI-Firmware), but where is it?. Or in other words: Is there a "System"-Battery, that would prevent my mac from forgetting the time?
Since I'm not running down my battery to 0 very often I only experience this issue from time to time and never took time to do anything about it.
iStats battery-Status says: Health:83%, Cycles:333, charge 50%...

So, back in the day, when my MacBook Pro's battery would die while asleep or on and you plug it back in, the laptop would essentially revive itself from your last used state. Its like waking from sleep, but takes longer because the computer has backup the memory state to the hard drive.
Its seems my MacBook Pro no longer does this. When the battery dies and I turn it on, it reboots. I am not sure if it is related, but I have modified my MacBook Pro by removing the optical drive and replacing it with an 80GB Intel SSD to compliment the 500GB 7200rpm Seagate. The SSD is the boot disk and is in the DVD Drive's old spot.

Is it OK to leave the MB on sleep. On my previous Laptop I never shut it down unless it was necessary, im talking the computer never shutdown for like 2 or 3 weeks of use. Not continuous use, I use the laptop 3,4 maybe 5 times a day and its kinda hard for me to wait for the boot up, i usually just close it (sleep) and go away. Can I damage my MB doing that?

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.
The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.
How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

Is it harmful to my macbook to leave the lid open in sleep over-night for iAlarm? I know it seems slightly naive, but is sleep different when the lid is closed versus open?

I just got my mac about a week ago. I'm currently arguing with my grandmother over whether it's better to leave the MBP plugged into the adapter all the time or let it drain the battery.

For the past month I think I've kept my macbook plugged into the wall. And the battery meter now says 95% but it says fully charged and the green light is on? Is keeping it plugged in hurting my overall charge?

My friend has a late uMB and his magsafe port is very very lose. Coincidentally, his battery stopped charging around 10 days after. His computer always runs on AC power and it says the battery isnt charging but it gains around 4% every hour. He thinks its because the lose port, but I think something else is wrong. Anyone have any ideas?

I recently was able to upgrade from a MacBook Pro Mid-2010 to a new MacBook Pro Mid-2012. I've only been using the laptop a few days, but it seems like the battery goes down from 100% very quickly. For example, right now I've only been using the computer for half an hour and the battery has gone from 100% to 71%. I haven't been watching movies, etc., just browsing the web.

I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

I sometimes forgotten to unplug the device before closing the lid. Such as when I'm in a hurry and close the lid of the MBP, only then realize that my iPhone is still attached.
I don't want to put unnecessary stress on the harddrive by it going to sleep, waking up, then sleep again just because that unplugging an USB device woke it up. I notice that this does not happend on my Windows laptop.

Whenever I close the lid to my MacBook it'll go to sleep by turning off the harddisk and the light is blinking. But when I go to pick it up or even move it the Superdrive makes a noise as if its searching for a disk and the apple on the lid/monitor blinks on and off. Basically the computer never really stays in sleep mode.

This is the second time this has happened. I shut my macbook expecting it to go to sleep. I then put it in its booq sleeve and put it in my back pack. About 40 minutes late I pull it out of the case and it is WAY hot and the fan is going like crazy. I open it up and I cant do anything, I think because it is over heated. What is the deal?
