Recently I've been noticing that my MacBook Pro's battery has been draining really fast. It's draining about 5% every 7 minutes. The battery condition is normal and it only has about 290 cycles on it. My brightness is turned all the way down, bluetooth is off and the only application I have open is Google Chrome, and I'm only using it to do some light browsing. Does anyone have this same problem? I have a MacBook Pro (mid-2010) running the latest version of Lion?

-Processor Speed: 2.8 GHz
-Memory: 4 GB
-OS X Version 10.9.3Â
When starting up it must be connected to the charger and when i turn it on it makes the bing noise, goes to the apple screen with the wheel turning for a second and shuts off. I have to do this multiple times until it works. Another issue that I am having is that the battery is draining very quickly. I just had it replaced a couple months ago.

I bought my Macbook Pro 13 inch last year in August. The health is on 88% with 84 cycles. Original battery capacity 5450 maH, current battery capacity 4809 mAH (Coconut and Istat Nano). I just read in another thread that there are users who have higher health capacity with many more cycles! I took it to the Mac store in Bangkok two weeks ago since I believe that my battery drains quickly. They run a test and told me that my battery is healthy. Then they also downloaded some updates for my Mac and run disk repair under disk utility. The technician told me that these are heavy programs and if they battery drains very quickly there is something wrong.
But according to him this was not the case. I have a 500 gb hdd and the technician said that since this is a big hdd (he recommended 320 gb maximum for 13 inch macbookpro), it will use more battery usage. I don't use heavy programs, only internet (Facebook, gmail, very seldom watch movies, watch news papers), Itunes and sometimes Word. I do a lot of photo processing, but this I always do with my adaptor plugged in. I think I can only use around 3 hours. Sometimes 4 hours. Screen around 80% brightness. Keyboard lights, bluetooth turned off. Do you think that there is a problem with my battery? Oh and I do calibrate my laptop monthly.

I have recently started using iTunes to listen to music while surfing the web or using other non intensive programs such as Inkscape. It appears that iTunes decreases my battery life considerably more than any other program that I use, even if I have a song on pause. While using iTunes my fully charged battery will display 4 to 3.5 hours of life remaining. When I have iTunes closed my computer will display a battery life of 7 to 9 hours, often with usage times the exceed that. Has anyone had similar experiences with iTunes and poor battery life, or am I doing something wrong here?
P.S. I have already calibrated my battery.

The title says it all, basically my MBP's battery drains even if the computer is plugged. When I sat at my desk to use my MBP earlier today I noticed the battery was charging. That seemed very weired, I was sure it was at 98% last night. I decided to switch my computer off and let it charge all the way up.
When I turnt on my computer again i checked the battery and everything seemed normal, but after half an hour or so I noticed that my battery status icon had chaged from charged to not charging. I loaded up Coconut battery and the battery was slightly over 90%...and it's still draining out while tipyng... The AC socket is fine and I have an HDTV connected to the same power source. Needless to say the tv is working normally... I do not have an Apple shop nearby, the closest is over 200 km (approximately 140 miles) away.

This morning I set to work on my laptop as usual. I typically leave it plugged in while not moving around, and today was no exception. I h ave a 15" macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.
Anyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). The power adapter light was green. I then stood up and did some work for roughly 2 hours away from the laptop. When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). This is nothing out of the oridinary, and I do it all the time usually.
What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep)Â to find that my battery had been almost completely drained. The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. The power source was still displayed as the power adapter.
I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before.
Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.

The last couple of days my battery has been draining extremely quickly, at full charge it indicates that I will get about 2 hours battery life when previously I was getting 6 to 7 depending on what I was doing. Also, I have noticed that the fan is running almost constantly and at high. I'm running os x lion and this is a late 2011 model MBP 13".Â

After installing the update for Mac OS (10.7.4) my battery starts too drain too fast. As usual after 100% charge my laptop showing me time near 5 or 6 hours. Of course I understand that this number is relevant, but i always get this numbers when using not so heavy apps (Safari, Mail, Pages, Twitter and iTunes), but now i can see only 2 or 3 hours. After long searches i found the problem. My MacBook Pro 15 inch have problem with graphic-card changing, it always changes to AMD Radeon card when I start Twitter or Reader! I think that Twtitter is not so heavy app that must use diskrete grpahic-card. And because I always run Twitter in background my MacBook Pro's battery drains in a few hours.

It shows a battery capacity of 5393 mAh out of 5770 mAh with a condition of "normal" at 93% health. The issue is that the battery has been draining MUCH faster than usual. Yeah I know it depends on what I'm doing/Youtube/Flash blah blah blah. I get it. What usually took 6-8 hours of normal time to drain is now taking 2 hours, max. I reset the PRAM, etc --- not much different. Now, here's the BIG issue. I have NEVER been able to recalibrate my battery because after it hits 10-15%, the computer just shuts off. It never goes into sleep. This has happened every single time. Has this ever happened to anyone before? The Apple Store is ways away, and I don't want to waste time going if they're just going to tell me my battery is "normal" since I haven't hit my 80% health indicator.

Several weeks ago I upgraded my mother's MacBook to Lion. I had also intended to buy lion for myself but my iMac's hard drive died.Since Lion was installed the MacBook's battery life has been very, very poor - even booting up can cost 5%. A lot of people gave been discussing this. I have googled this issue and emailed Apple, but there seems to be no solution on the horizon. So I am going to reinstall Snow Leopard on the MacBook.  I had intended to contact Apple to see if a refund would be possible. However, just yesterday I replaced the hard drive in my iMac and it is working fine now. So I was wondering since I paid for the Lion OS, is okay for me to install it on my iMac rather than attempt to get a refund. Is that legal? And would it work? Would the fact that it was bought using my mother's AppleID (my money though ;)) mean that if I install it on my iMac it will make my computer my morher's computer - meaning my morher's login and details will overwrite mine?Â

I installed the hard drive with no problem and have experienced greater performance, no clicking nor vibration, and no freezeup or rainbow wheel. I also did a clean install of Snow Leopard. I did a PRAM reset at the beginning and calibrated my battery. However, now I noticed my battery is draining FAST, only lasting 2 hours. I looked a little online and discovered I may still need to reset the SMC (shift-control-option + power key), which I will do shortly. The battery lasted 6-7 hours before with my old hdd and is at 96% capacity.

My MacBook shuts down when the battery drains all the way down. I'm pretty sure back in the days of PPC lappies, they went to sleep before the battery died. Is it supposed to shut down, or is something goofed?

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?

I bought a MacBook Pro September 2007, the last months I have experienced a sudden shutdown of it without any low battery warning. After browsing around the forums I found a app called Coconut Battery which I installed. This is what it showed me: What I can do to get my battery performance better? Do I have to invest in a new battery? And aren't the prices on those extreme?

My 17 inch Mac pro laptop just shut down and I can't get it to turn on again. This has happen multiple times over the last six months. Looked through the forum and tried removing the battery and resetting the SMC control to no avail. I was having issues also with the screen a month ago but that resolved by itself. When I took it into the genius bar for screen problems I was told I'd probably need a new CPU board because the vram may be going bad and they just don't fix that problem. Have held off because of a potential $500 repair and awaiting ivy bridge technology. How I can restart my portable. Right now you turn on the machine and the front light stays on for 2 sec and you hear the machine click off?

I've been having an issue with my Macbook Pro, it keeps turning off while on battery power while I am playing a game (Starcraft II) despite having sufficent charge remaining. It won't turn back on until I plug it back in. Usually when I turn it back on the time and date are reset and the password to my wifi has to be rentered. The most recent time this happened after I plugged it back in the battery still had 79% charge remaining. I've tried recalibrating the battery and resetting the SMC both which did not solve the problem. The system report states that the battery's condition is normal and I ran a hardware test which also came back normal.

I've update my hdd from my macbook pro 13" mid 2010 to an ssd. I've done a fresh install and imported all my apps and settings from my old hdd. Since that time I have 2 problems: when my mbp goes out of battery it shut down instead of hibernating and when I turn it on my finder is indexing my home folder! I have hibernate mode set to 3 as normal.

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?

I have a MacBook, which runs OS X 10.4.11 with a 2GHz processor and 2BG 667 MHz DDR2 SDRAM memory (whatever that means). Anyway, I've recently got a T-Mobile USB Broadband stick (it's awful and I feel bad that my girlfriend bought it me, so don't ever buy one!) and I discovered yesterday, after much experimenting, that it was this that is running down my hard drive space considerably. I deleted around 10Gb of user support that I didn't need, and within a day it was gone. When I'm not using it, the space on the HD remains the same. I'm not downloading anything and have hardly streamed anything other than a few Spotify songs. My question is, where is the space going and can I get it back? I downloaded OmniDiskSweeper, and there is a log file of 10Gb. The log file is called 'console.log.5' and in the folder called '501' in the 'Console' folder. Can this be deleted without consequences?

I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!
