MacBook Pro :: Battery Gets Empty In Sleep Mode / Battery Having Less Capacity?
Nov 14, 2009
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 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 was calibrating my MacBook Pro's battery and when I was running the battery down, after the point where the "Low Battery" warning popped up, it ran for 9-10 minutes and the computer just shut down. Let me mention that my battery has no problem lasting for 7 hours. What could be the issue? Is this normal behaviour?
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.
The past few days whenever I select sleep mode on my MAC the next morning my battery is dead. The frist time this happened my battery was at 100% - last night it was at about 75% when I selected sleep mode. This morning the battery was completely dead?
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 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?
I just got a Mac Pro Octo 2.93. It has a 4870 card and 4 1tb drives. I also have a Sonnet E4P e-SATA card installed. Would a 780 Watt 1200 VA surge suppressor be enough?
The other question is about waking the computer up. My old G5 Quad (7800 GT card, E4P card, 2 500gb drives and 8gb RAM) would wake up and while the afore mentioned surge suppressor would beep, the room electrical breaker wouldn't be tripped. Using that same suppressor for the Mac Pro results in the breaker being tripped when the computer wakes up. Would getting a bigger suppressor help with this? In other words, does a unit with a bigger battery capacity allow the battery to take the extra load when the computer wakes up preventing the breaker from tripping?
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.
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.
My AppleCare expires on Monday September 6th, and I am wondering if my 87% capacity at 51 battery cycles suggests I should visit an Apple Store this weekend? The closest store is around 25 miles away, so if I would be wasting my time, I would rather not take the trip. My concern is mostly based on my warranty ending. This is a 2009 13" MBP.
I used an app on my MBP called Coconut battery. it said that my current battery capacity was 94% of what it was since I bought it. I assumed that means those 6% are never coming back and I should start using it more responsibly to make it last longer. I read a lot of forums on how to use your notebook effectively, when to plug it in, how much I should let it discharge etc. After 2 weeks of my new habits, I checked my battery life again and now it says 96%. Is it even possible for it to go back up?
I have MacBook Pro about 17 months old (bought new Summer 2008). According to Coconut Battery, my current battery capacity is 96% after 185 cycles (see below). This was taken just after I re-calibrated the battery last night. I usually work the laptop from the battery ... I rarely leave the laptop plugged in unless charging, and when fully charged I always unplug and run the battery down before plugging in again. So, is 96% battery capacity good or bad for a 17 month old MacBook with 185 charge cycles? Is the way I'm charging ok, or is it better to have the MacBook plugged in continuously and have less charge cycles (would this give me a better battery health %)?
Charge remaining (mAh): 4292 Fully charged: No Charging: No Full charge capacity (mAh): 4919 Oddly enough, I can't even reach 4 hours. 50% screen with web surfing/msword. SDD version.
Got a question about the battery in my wife's white Macbook. I just downloaded (and ran for the first time) Coconut Battery and it reports the following info:
Current Battery Charge: 5281 mAh Maximum Battery Charge: 5281 mAh
Current Battery Capacity: 5281 mAh Original Battery Capactiy: 5020 mAh
Battery-LoadCycles: 60 Age of your Mac: 8 months
Now, I'm no rocket scientist, and I'm definitely not complaining, but how in the world does my battery have More capacity now than it did when it was new? Is this an error in Coconut? System Profiler reports the same capacity and my research online seems to concur that 5020 mAh was the original capacity.
I've got a 4 month old Macbook Aluminum 2.4 ghz. I was getting great battery life for the first couple of months. But I'm now getting 3:10 with screen half light, and wifi on, bt off, doing a bit of downloading, etc. I've recalibrated the battery a number of times. According to activity monitor my cpu is hovering under 10% when I'm doing my battery test. This is at least 2 hours less than I was originally getting. Coconut Battery tells me that the original capacity was 4100, but its currently at 4052. Battery load-cycles are at 97 and it says the Mac is 5 months old. Should I take it in to the Apple store under AppleCare?
I bought my MacBook Pro 13.3" 5 months ago (according to Coconut Battery) and the battery-loadcycle is already at 51 and 89% battery capacity. Anyway I wanted to know, if I keep my Mac plugged in on the charger will the battery-loadcycles decrease?
I get ready for the next disappointment tomorrow (maybe no MBP update) and looking out for a MBP at eBay. I've found a good one (August 2009) 2.53 GHz, 4 GB RAM, 500GB HDD etc. for round about 900� (1.200$) (in Germany we pay 1533� for this model so round about 2088$). The guy sent me a screenshot of the battery capacity which is 87% (4762mAh) after 56 loadcycles. Is that acceptable? IMO it's a bit too low - what do you think? Maybe I'm going to buy a AppleCare Protection Plan afterwards ... would the battery be covered?
I've had my Macbook Pro for just over 2 years and recently bought one of the 2010 models. I'm about to sell my old one but when I downloaded Coconut Battery, I saw that my battery holds a lot less charge than it did when it was new: Have I been doing something wrong or is it just low because the laptop is 2 years old? If it's something I've been doing, I don't want to make the same mistake with my new one.
Is there any way to reset the original battery capacity? This is a new MacBook pro. I am using coconutBattery and it says my original capacity is only 1300mAh. My current capacity is 12718mAh.
Apple say MacBook Pro early 2011 should have 7+ hour capacity. Mine dries out in less than 2 hour. Beside: The computer gets very warm, cannot contact to a table without damage the table.
Info: MacBook Pro (15-inch Early 2011), Mac OS X (10.7.3)
I just logged on to my macbook and it said 96% fully charged. I got really worried and installed coconutbattery and it says my maximum capacity is 98%! I've only had my mac for 4 days!
Please post your battery capacity on your Gen 2 Air. Just received mine on Thursday. I have the following unfavorable results. Capacity: 4789 mAh 94% Life Original Capacity 5090 mAh Battery loadcycles 11 Age of my Mac 2 Weeks.... Am I correct in assuming that my capacity should be around 5200 mAh and that this is indeed a defective battery? Please share with me if I am incorrect, as web browsing after a full recycle is about 2.25 hours, without doing anything else.
As in thread, I noticed in CoconutBattery and in iStatNano widget that my battery is losing capacity, yesterday I had 96% now I see 94%, I've got my MacBook since May and it has 59 cycles yet.
I think that it shouldn't lose capacity now, ok, later but now is to fast, do you think so? Is there any solution to increase this capacity? I've got MB Unibody 2GHz, Late 2008, but I bought it in May 2009 "as new"..
