MacBook Air :: Battery Drains Extremely Fast In Sleep Mode / Battery Down To 16% From 29%
Jan 6, 2009I 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 :: Folding Drains Your Battery
Nov 24, 2009My two month old MacBook Pro has suddenly developed what seems to be a battery problem. Can someone check this to make sure of it's legitimacy, the Energy Saver Settings are set for better battery life. I had been getting 4-5 hours with tons of apps open doing Word Processing/Internet on medium screen settings. This is on the lowest screen setting, Adium, Safari, Mail (and Coconut) running.
View 6 Replies View RelatedMacBook Pro :: Battery Drains While Shutdown?
Feb 3, 2010I'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, 2010I 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.
I will check it out tonight just to make sure I was right re the charge before bed.
I calibrated it last week.
Any thoughts? both 15 and 17 should get the same battery time?

MacBook Pro :: Battery Drains One Percent Per Minute
Jul 31, 2009Ok 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

MacBook Air :: Battery Drains Too Fast When Sleeping?
Apr 30, 2012I 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?

MacBook Pro :: Video Game Drains Battery Even When On Charge
Sep 13, 2010I'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.
MacBook Pro :: Battery Drains Fast While Sleep Mode
Jun 29, 2009I 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.

Dec 5, 2014I 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.

MacBook :: Can't Keep Screen Backlight On
Dec 15, 2010I kept my macbook (late 2008) turned on overnight on lowest brightness and when I tried turning the brightness back on this morning, the backlight flashed on for less than a second and then turned off again. Somehow I managed to get it to work, but whenever I move my macbook even slightly the problem reoccurs. I've done some research on my problem and I suspect that it's hardware related (maybe the inverter or the inverter cable?), but maybe the LCD itself is broken? Does anyone else have any experience with this?
View 1 Replies View RelatedMacBook Pro :: LED Backlight On But No Picture?
Jan 22, 2009I have a 2.2 Santa Rosa 15" MBP, and an odd thing happened last night. I wasn't running any unusual applications, and had a few things open and was browsing in Firefox. All of a sudden my screen went black, and wouldn't come back up.
The computer is still running just fine, and it didn't go to sleep. The LED backlight is fine, as the Apple logo is lit up and if I change the brightness I can see the backlight changing (the "black" screen gets less "black", if that makes sense), however the actual display panel isn't projecting any picture at all.
I've restarted a dozen times, reset PRAM, and did the unplug battery and hold power button trick, all to no avail. There's no flicker of a picture or anything... it's as if the monitor is completely dead (aside from the backlight being fine).
If I plug in an external monitor, I can use the computer just fine. So it's not like the video card is dead all the way.
MacBook :: Backlight On Keyboards
Feb 8, 2009I know that the base 2.0GHz MacBooks do not feature the backlit keyboards of the higher-end models, but I was wondering if the actual backlight is physically in these lower-end models and just disabled in firmware or software? Or is it missing entirely?

MacBook :: Aluminum Backlight Went Out - Replace?
Dec 8, 2010The backlight on my MacBook went out suddenly today, no idea why. Is there some way to replace it without having to replace the entire display assembly? It is very difficult to get the assembly apart, but I will be on break from school and will have plenty of free time to fix it if it will save me a few hundred bucks. So is it possible to replace the backlight only, or is it a part of the lcd panel?

View 7 Replies View RelatedMacBook :: Screen Won't Turn On / Backlight
Dec 26, 2010I have a 2008 White body model Macbook with 2 gigs of ram and 2.1 core duo processor. My problem is that the screen won't turn on...when I start up my computer it lights up for a second, but turns off before the apple sign shows up. If I look really close I can see everything. Oddly enough, if I press the brightness button so to decrease the brightness to the very last bar and then hit the f2 button to turn up the brightness by one, the light will turn on for a few seconds, if i continually go back and forth, I can sort of use it enough to do something with it (thank god because I had all my work for school on it). I have included a link with this thread so you can see what I mean.
