MacBook :: X Over Battery Icon And The Fan Is Running Even Though No Heavy Duty Performance?
May 20, 2012
Earlier today, maybe around 3PM, I was using my laptop, and it was charging and it was maybe around 60% battety life when out of no where it just shut off and even the light on my charger went out. When I turned it back on, the fan was running and there was an X over the battery icon. I've tried turning it off and on, and leaving it alone for a few hours, to see if it would resolve the problem but it didn't. It is currently 9:52PM, I'm still experiencing these problems and I'm using the exact laptop to type this, but I don't know how much battery life is left.

MacBook, Mac OS X (10.6.8)

I'm looking at both the i5 and i7 15" MBPs and I'm trying to find out how well each system would handle COD. I'm sure the i7 model would do much better since it has twice the VRAM. Has anyone here played either game on their MBP and if so, what type of FPS were you seeing?

I am not sure if it only my macbook, but I notice a slight performance drop when I run on the battery v the AC. I notice that my application load slower, folders open slower and expose and spaces response is also slow as well.

The battery icon on my macbook pro has a 'X' on top of it. The machine turns off as soon as i remove the power cable from the mac. It turns on only when i remove the battery and again put it back on. Once i do this, the battery shows 100%. After i leave it connected to the power for an hour or so, the 'X' appears again!! My macbook is not under warranty.
Its a 15 inch, Late 2008 model running on OS X 10.9.4.

I was running some networking performance tests the other day for some research project. Essentially I have 7 computers on a LAN that is not connected to the Internet - all computers are connecting wirelessly. I have one computer function as a server and it multicasts pings to the other 6 computers at a constant rate (e.g. sends a packet every 2 seconds).I noticed some odd behavior - 4 computers received the packets in about the right time intervals (every 2 seconds), but 2 would get packets at intervals of roughly .92 seconds and 1.12 seconds consistently. I realized that these 2 computers were running on battery and not plugged in. Plugging in all computers got all the computers receiving packets at the same time.

Apple Macbook Air late 2010, has been giving me poor battery performance even after replacing the battery under warranty. I am unable to find a solution, even the local apple service provider seems confused. Should I go for a replacement?My Macbook Air runs on the OSX 10.7.3 with all updates as on date. I use only softwares such as Microsoft Office for mac, Safari, Mail, iChat, iTunes regularly.

Has anyone tried running multiple virtual machines on these guys yet? I'm looking to run base installs of different OS's for my InfoSec classes. I'm really just testing different security configurations nothing fancy.
I'm looking at the 11.6/1.4/4gb of ram. Most of the time I'm only running 2 Virtual machines, just want to know if it can handle them.
I've seen some people have got win7 to run which is cool but the second os running is critical in this scenario.

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!

I just turned on my 13" MBP and got this message. Apparently, this is supposed to come up when there is only like 5% charge left. My battery indicator at the top of the screen said there was 22% charge left. Also, according to IStat, my battery's health has already dropped down to 97% after only about 2 weeks and 5 cycles. Is this normal? I'm going to try recallibrating my battery by fully charging it and then letting it fully drain. Is there a good chance that this solves this problem?

i remember in Leopard you were able to select different profiles in the battery menu on the menubar. There was an option for high performace and power saver, etc. In snow leopard this is not an option, is there anyway I can bring those settings back? Or is snow leopard automatically adjusting processor power?

Just wondering what the norm is in terms of where my battery levels should be. When I first received my MBA 2 weeks ago, the full charge mAh capacity was around 7100. Now after 6 cycles, the full charge max mAh is 6678.
Is this normal for the max to drop so much after only 6 cycles? Just wondering what others are experiencing in terms of battery performance.

I have a MacBook (late 2007) and I've noticed that my internet crawls when I'm using the laptops battery power. I can be downloading a file at 200 kB/s under A/C power, and as soon as it goes on to the battery it'll drop to 10 kB/s. I'm assuming some kind of power saving is being activated, but this has only happened recently. Around the same time this started happening, I updated my computer to 10.5.8 and I also turned in my computer to the Apple store to have the palm rests replaced for having cracked under the weight of the lcd. Would this problem be caused by either the update or the repair, and if not, what could be causing it?

I just switched my old 120Gb drive with a 320gb one (FUJITSU MJA2320BH G2 -- speed should be the same as my old one), and I'm noticing a drop in battery performance of about 20%. Is this just a coincidence?

I just ordered my first mac a few days ago online, and seeing that almost everyone takes advantage of the suposed 10h battery of the 13', I wonder if it gets slower when you are using the battery.
my current notebook (compal FL90) is considerably (much) slower when it is not powered to the grid especially if I'm running photoshop for casual editing.

increasing the amount of RAM in a MacBook Pro (latest model unibody 15" i7 processor). If I increase the amount of RAM in this laptop from 4Gb to16 Gb, should that in and of itself result in a decrease in battery performance? This is assuming no increase in number of active programs, etc. A friend of mine was told by an Apple employee that just increasing the total RAM in a laptop would result in the battery draining more quickly. I am no computer genius, but that does not sound right to me? After all, why should the battery work harder if the excess RAM is not being used at the time.

What effect will the macbook have, if i fully charge and discharge the battery on a daily basis. I will leave it running on battery power when i leave for the day, and let the battery drain/discharge fully through the night.I will hook it back up in the morning to have it fully charged, may be 30 - 60 mins after it being fully charged, i will pull the power out and run the laptop the whole day on battery.

I know that Flash uses more battery power. However is that only when you are actually using a window that needs Flash. Does just installing it decrease your battery performance in any way? I am running into lots of sites that require Flash and I would like to install it but not at the risk of severely limiting my battery usage when not actually using it.

I am planning to buy a new 13" MBP but I am kind of concerned on the battery performance.
Specs:
a) 2.26 GHz CPU
b) Upgrade RAM to 4GB
c) Upgrade HD to 500GB 5400 WD
d) Brightness at 70% / with keyboard backlight / Bluetooth OFF
Questions: (Can you give me an estimate on the following)
1) How long will the battery last if I play Facebook games nonstop (poker / mafia wars / cafe world / etc.)
2) How long will the battery last if I play Sims3 nonstop?
3) How long will the battery last if I watch a DVD movie nonstop? (from the drive)
4) How long will the battery last if I type documents nonstop?
BTW, can this MBP 13" play sims3 in the default normal settings?

calibrating my battery for the first time this morning. i just opened my macbook pro to see that the time left icon jumps every minute. it goes from 8:50 to 12:38 to 6:54 to 11:37 to 7:40! and now it went from 8:45 to 9:19! the percentage remaining is consistent and correct but the time left is way out of whack! sorry for the slang! now it went from 9:19 to 9:11 then 8:47. i have the screen at the lowest brightness, no backlit keyboard, nothing else running except firefox. i wasnt aware that i was supposed to calibrate my battery and its been about 3 months since i bought this. now its at 8:37 now 8:18. this is quite

Planning on Purchasing one of the New Aluminum MacBook Pro's. I would like to know what are the best ways to have your battery last longer and hold the normal charge? Also on the Battery Section on [URL] it says it not good to have your computer charging all the time but then people on the forums say it's better to keep it plugged in! What is it? What should I do? Listen to Forum users or Apple). Also what is a good setting for the Screen Lightiness? Is HalfWay see able? What about 75 percent notches. Will lowering the battery brightness save battery?

I've been looking for some info on the older 2007 MacBook Pro battery specs and stats, etc., but have been somewhat unsuccessful. Lately my MBP has been draining the battery at a much quicker pace than normal. This machine is only a year old now (however CoconutBattery says the battery is 16 months old). Still, the battery capacity shouldn't have diminished too significantly. Before I restored the Mac and installed the Windows 7 Beta, I could average 3-4 hours on a full charge. Normally, I would keep WiFi + Bluetooth enabled, an external monitor attached, several USB peripherals plugged in, and the main display would be set to maximum brightness. 3-4 hours was pretty nice considering the amount of power the machine could have been using.
After I partitioned my hard drive, the battery life was cut in half on the OS X side. Windows 7 power management was even worse. I figured that there may have been extra disk activity causing this problem. After I finished toying with Redmond's new OS, I removed the Windows partition and moved on from there. I know after I removed the partition, I was getting excellent battery life initially. Once that short period ended, it went downhill from there. The battery meter has become surprisingly accurate as of late; in a minute or so, you can easily watch the percentages drop 1-2%, which appears abnormal. I can manage 3 hours on a single charge at best, but I usually get less. I decided to take greater care in cycling the battery, in hopes of nursing it back to health, so to speak. It doesn't appear to be working so well. Enabling WiFi and other peripherals only drains more power, but turning them off again adds only 5 minutes. So when I'm using several devices at once, I'm lucky to get a little over 2 hours. Turning off menu items and background apps does nothing either.
It's been this way for several weeks now, and yet, iStat, System Profiler, and CoconutBattery all report seemingly acceptable and consistent battery info: 86% Battery health, around 180 charge cycles, and the capacity is around 4700mAh (out of the original 5500) for now. The computer believes all is well. Performance says otherwise. I'd like to think that physically the battery seems to be okay. I've cycled and calibrated it several times. I have read reviews that indicate that Santa Rosa MacBooks with new batteries have averaged similar runtimes to the ones I experience now, but I know mine has usually bested all of the reported tests. It just seems wrong for the average runtime to go from almost 4 hours to 2 when the battery is (supposed to be) maintaining the same health level. I have AppleCare if it needs to be replaced, since this drastic change in usage time is very noticeable and counterproductive for me, but it could just be the computer (or me for that matter). Is this behavior normal for a battery of this age? What should I look into? If this is normal behavior I can live with it, but I would prefer to get as much out of the one I have.

Starting this morning an X has appeared over my battery icon. When I click the icon is says no battery available. When I check the system profiler it says no battery installed. When I click the button on the battery all 6 lights turn on. I have read similar posts to this that say when they unplug the power supply the mac turns off in a few minutes, mine however will stay on the same amount of time as if the battery was charged. I'm surprised that this happened because I bought a new battery 3 months ago because the original one short circuited when my hard drive went last summer.
I had to have the power supply constantly plugged in if I was using the computer. I tried shutting down the computer, removing the battery and restarting and that worked. However when I shut down, unplugged the power supply and tried to restart, it did not turn on. I'm hoping there is a solution as I use my laptop on the road often and not being able to turn it on without the power supply is a real inconvenience.

I don't get this. My mom's white MacBook (Intel IGP model) showed an X across the battery like it doesn't work, so I bought her a new battery for it. However, I installed the new battery and it still shows an X but it actually does work. I figured it out by accident. I thought maybe I bought a bad battery. I tripped over the magsafe and the MB stayed on... confused, I am now here. Not finding much about this.
What causes OS X to display an X across the battery icon? Doesn't this usually mean the battery is ruined? When pushing the button on the bottom of the battery, it shows five LEDs as it's fully charged and working. I unplugged it several times, and the MB stays on.
It also reduces the screen brightness and seems to go into battery power saving settings when unplugged. So how do I get OS X to see the battery? It must be charging properly as it's not hot or bulging or anything at all.
The problem is simply that it's not showing the battery information at all as though there were no battery plugged into the MacBook. But it works as though it's plugged in and all is normal?

I have a late 2007 MBP 15inch 2.33Ghz Core 2 Duo. I have had since new and no problems. Over this last week I have had the same issue a couple of times. The MBP just switches itself off. The first time it did it, it was running on battery (I was using Aperture) and had 60% power available. It would refuse to re-start until I connected it to the mains and then it ran fine.
Then it did the same thing overnight at some point. I had left it connected to the mains (as I always do at home), had shut the lid to put it into sleep mode. When I came back it was switched off. No-one had touched it whilst I was away but yet it had just turned itself off.The only thing that I noticed was that when I started it up both times the little light on the magsafe connecter kept flashing between orange and green. However when the computer booted into OS X both times it showed a reasonable amount of power in the battery.
