MacBook Air :: Battery Drains Extremely Fast In Sleep Mode / Battery Down To 16% From 29%

Jan 6, 2009

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!

MacBook Pro :: Battery Drains Fast While Sleep Mode

Jun 29, 2009

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.

MacBook Air :: Mid 2013 - Battery Drains Entirely During Sleep

Sep 7, 2014

Mid-2013 MBA.  Computer does not seem to sleep when the lid is closed.  Battery drains completely.  SMC update has been run.  OSX 10.9.4.    No peripherals attached, Bluetooth is off, network sharing is off.  In Console I see at least three "Sleep failure" messages...they all begin with 0x00000000 but then have different codes.  They are 0x21006c00, 0x1f006fc00, and 0x1f006500.

MacBook Pro :: The Battery Turn Off While In Sleep Mode?

Jan 7, 2011

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).

MacBook Pro :: No Sleep Mode When Runs Out Of Battery?

Jun 2, 2010

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.

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?

MacBook Pro :: How To Activate Sleep Mode At 5 Percent Battery Automatically

Mar 28, 2012

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]

MacBook Pro :: No Sleep Mode At Low Battery - Data Loss And Time Reset

Mar 13, 2012

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%...

MacBook Pro :: Battery Drains While Shutdown?

Feb 3, 2010

I've got a 17" Macbook Pro from May of 2007 that is serving me well now in my last year of college. The battery health began to deteriorate last year so I replaced it with a new one from Apple (a hefty $120).

Recently, the past two times that I have left for class (with my MBP fully charged) it has drained while shutdown (completely turned off NOT just "asleep"). When I say it drains, I mean it has roughly 2-5% of its battery life left giving me about 20 minutes of power until I get back home for the day.

Here's the kicker: the battery is in good condition with plenty of cycles left (see system profile for power below.)

Any thoughts? Try a new battery? Could it be the charger? What system components, if any, run during a complete shutdown and could these be malfunctioning?

MacBook Pro :: MBP Battery Drains While Sleeping?

Jun 13, 2010

I returned my 17 i7 MBP for a 15 i7, I have been torn between the 2. My question is the 15 battery seems to drain alot while sleeping. last night I was around maybe 40% and went to bed and now its 0%. coconut battery says 100% health. The 17 did not drain that much over night.

MacBook Pro :: Battery Drains One Percent Per Minute

Jul 31, 2009

Ok so to start off, my Macbook Pro is around 3 years old. With my original battery having been through 350+ cycles, I had to buy a replacement. So I did some research and found that the Fastmac battery was my best bet for a long-lasting, reliable battery. I would say that Ive had the Fastmac battery for a bout 6-7 months without any problems whatsoever. However, recently Ive been noticing the drastic change in battery life. I installed Coconut Battery yesterday and discovered that my current battery capacity is 2266mAh with the original capacity being 5800mAh and 213 cycles. I also should note that the battery drains 1% a minute with no programs running (besides the Activity Monitor, which showed no strange behavior). Now luckily for me, My Fastmac battery is under a 1 year warranty, however I just wanna verify that it is a fault with my battery and not anything on my Macbook's side causing the battery to drain so quick. The last thing I want is to receive my replacement and then have to go through the same process 6 months later.

Also here is the Battery Information from the System Profiler.
Battery Information:
Battery Installed:Yes
First low level warning:No
Full Charge Capacity (mAh):2266
Remaining Capacity (mAh):1414
Amperage (mA):-1449
Voltage (mV):11421
Cycle Count:213

MacBook Air :: Battery Drains Too Fast When Sleeping?

Apr 30, 2012

I purchased a Macbook Air 2011 in December. It came with Lion preinstalled and it is up-to-date. Sometimes I experience excessive battery drains when the computer is asleep (lid closed), i.e. 40%-50% battery charge gone overnight.

This is not an expected behavior. The battery seems to perform well when the system is running, i.e. it last for 5-6 or more hours, so I think the problem is with the sleep mode. How can I diagnose sleep problems? Is this due to WiFi or running programs?

OS X :: MBP Reboots After Dead Battery In Sleep Mode

Jan 21, 2010

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.

MacBook Pro :: Video Game Drains Battery Even When On Charge

Sep 13, 2010

I've been playing Starcraft 2. I played first in Leopard but the performance was no good unless graphics were set to low. Even then, it was only just playable. So I switched to XP. Gameplay on medium graphics is great in XP. I've noticed that even though my Macbbok Pro is plugged in to the wall, it drains the battery. Last night I played so long that the computer shut down after the battery ran out of juice.

Specs: Macbook Pro 2.4, 256MB 9600GT, 2GB of ram (I have 4GB coming in the mail.) Leopard fully updated. Windows XP fully updated. I am plugged into the wall, not a surge protector.

Software :: System Not Exiting Sleep Mode / Kicks Back Into Sleep Mode

Dec 29, 2009

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.

OS X Yosemite :: Battery Drains Faster After Upgrading

Dec 5, 2014

I have bought MBA last month only. I could see the battery back up will be for 13 hours if I charge completely. Few days back I have updated OS to 10.10.1. Battery back up has been fallen down to just 3 hours after complete charging. I will either use safari to browse or see some videos. I have checked the condition of the Battery. Its showing Normal. No apps are using significant energy as well.  Also it significantly increases the heat which I have never seen while using Mavericks. What should I do to get back my 13 hours battery back up.

Mac Mini :: System Keeps Going To Sleep Mode / Preferences Are Set To Never Sleep

Aug 10, 2009

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.
