MacBook Pro :: Fan Runs Constantly From Startup / Battery Life Getting Worse?
Oct 20, 2009
I've got an early 2008 Macbook Pro and, recently, I've noticed that the fan (fans?) begins running from the moment the computer is powered-up. iStat tells me that both fans are running at about 2000 rpms, though I only hear a slight whoosing noise from the left side. I don't remember the fan running constantly, and I have noticed that my battery life seems worse than normal recently. Is this normal, and something I just haven't noticed until recently?

Ever since I upgraded my Macbook Pro (mid 2009) dual core from Snow Leopard to Lion, the start up time has increased significantly, and the battery life seems to be lower than it has ever been. It has been several months since I upgraded so indexing is not an issue. What should I do, and how can I get back my missing battery life that Lion took away? And how can I make my reboot and startup time faster.

I calibrated my battery last week and I'm pretty sure I'm getting worse battery life after the fact. Has anyone had this experience? Can battery calibration hurt your battery?

Have noticed this recently, mainly since the 10.10.1 update.
It's a 2.66 Intel C2D with 8 gigs of OWC RAM and a 240GB Crucial SSD
I work mainly from home and have it at my desk. It's hooked up to an Apple Cinema HD Display 23"
All updates done to software, permissions repaired, PRAM flashed, etc
Turned down the transparency, turned off some items in spotlight search, still no change
Info:
MacBook Pro (13-inch Mid 2010), OS X Yosemite (10.10.1)

Black MacBook fan runs constantly. I found a thread here that looks helpful: [URL]. Following suggestions there I looked in Terminal at the top cpu processes for a rogue process that's overloading the cpu and keeping the fan running. What I see is a "COMMAND" called "DriverSPd" with a PID of 157* that often runs the cpu past 90%. Do you know what Driver SPd is? Can I kill it (without killing my MacBook?)

Just wondering if anyone has ever encountered this or if any experts out there know of the issue.I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.

i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.

I calibrated my MacBook Pro battery and then noticed that the battery life seemed slightly shorter after that. I calibrated it according to this: [URL]
Just wondering if I have done anything wrong...
One more question... What do they mean by "At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep." Does it mean that I have to use the computer until it just shuts down or should I shut it down once the "Low Battery" warning pops up?

As the title says, my Macbook Air running freaking amazingly hot ever since the latest Mac Update. Any ideas, I can't find anything in the Activity monitor that could be causing my Macbook to be running so hot.

I have a 13" 2.4 GHZ white macbook that I bought in march of 2008. About 4 months ago I all of the sudden started having problems with battery life. It was very abrupt. I used to be able to take my macbook and sit through 3 classes or more with no trouble in regards to batter life. Then suddenly the battery would drain within a few hours. It has remained that way since.
I've spent the last month or so looking around forums and other places to try and find someone with a similar problem and possible solutions. As a result I've discovered that my situation seams to be somewhat unique.
Using cocoanut battery I tested my battery's capacity and it remains at a solid 98%. How can my battery still be at 98% capacity and have such a short battery life? I also seam to be losing charge while my macbook is closed. How and why does that happen? If I leave my macbook closed for a day or two it can lose up to 25% charge just sitting there!
I've tried loads of things including turning off unnecessary things such as sharing and bluetooth and calibrating my battery, all with no avail.
What is going on?? My battery is too old to be eligable for a recal and I'm not paying $30 just to have a phone conversation with a "Genius". If anyone has any idea what's going on and any possible advice, I would greatly appreciate it.

I am getting a very short battery life out of my "New" A1261 battery - we're talking 2.5 hours tops. I've recycled it a few times, but this is no where near the "7" hours that is quoted.

I have one of the black macbooks with c2d, a GMA950 graphics card, and 2 gig of ram. When I run Windows XP in Fusion, the fan runs almost constantly - even without any windows applications running (antivirus is running). This bothers me.
It's getting time for me to consider a new laptop. Does anyone have any experience with the GeForce 9400M or 9600GT video card laptops? I'm wondering if my experience will be different with either video card.

I've had this MBP for just over 8 months now, I'd intially purchased one in november, but the audio out used to give a crackle sound so they replaced the laptop. Moving on to the point - in the last week or so, I've noticed the MBP suddenly seems to get very hot and the fans turn on and thus suddenly becomes very noisy. I was using it on the bed so could appreciate that I may have been blocking the vents, but I've had it on a stand the past couple of days and it still seems to do it for no particular reason. The charger usually always gets ridiculously hot, but the MBP used to stay relatively cool, now the MBP gets hot independently of whether its being charged or not. Moreover, my battery life has gone from what used to last 4 hours, to around 2.25.
Cocunut battery gave the following stats:
Current Battery capacity: 4483mAh
Load Cycles: 222
Age: 8 months

I have just bought a MacBook. I have downloaded the Battery Health Monitor and it says obviously that my current capacity is at 100%, with 5,791 mAh. I would like to know how many hours does this value correspond to, because it has certainly not been the highly announced 10 hours battery life

my new white macbook runs slower on battery that when it is plugged in. The most noticeable thing is that the applications folder loads slower and is laggy to scroll in.
Unchecking put harddrive to sleep when possible did not fix the problem.
Any ideas or is it supposed to run slower to save battery?

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.

Anyway, sometimes I'll leave my MacBook Air on without the power adaptor attached, and the battery will drain.That's all fine and dandy.The problem is, is that instead of going to sleep LIKE IT SHOULD, it will completely turn off, and everything I had up (web pages, anything and everything) will be GONE when it starts back up.

I am interested in getting a refurbished Macbook Air. I was looking at the following two models:
Macbook Air Rev B., 1.86 GHz, 2GB RAM, 128 GB SSD for $1349 OR
Macbook Air Rev C., 2.13 GHz, 2GB RAM, 128 GB SSD for $1549
Other than the processor difference of 0.27 GHz, and based on reading the technical specs of each system, I don't see any difference between the two machines. The one piece of information that I couldn't find was the advertised battery life for the Rev. B unit. The Rev. C unit is supposedly rated for 5 hours of wireless productivity. Is the same battery used in the Rev B also or is the battery of lower WHr?
My needs are pretty simple - I would like to get the Air as a small and portable, easy to carry machine for rounds and writing up patient notes, consult notes, etc. It will not be my primary machine, but hopefully a worthy road-warrior. I will be using Windows for the clinical electronic medical record application, but other than that, all other use will be on Mac OS X. Based on this, would you recommend going with the Rev B or Rev C. Money is tight, and this will be a gift from one of my mentors, but I do want to get the biggest bang for the buck. If the only difference between the two machines is processor speed, I can't justify spending 200$ extra just for a 0.27 GHz gain.

I have a 2007 White Macbook 2.4 Intel Core 2 Duo Laptop. I purchased it in June 2007 and this is my current battery health. Check the picture below, It's pretty amazing and I don't know how I did it. I'm on my computer almost everyday. Any idead on what I did to get such great battery life after three years? I know people with newer MacBook Pros that have terrible battery life after a year and a half.

I bought a 1st Gen Macbook Air in March of this year and I recently have noticed that my battery is not lasting as long as it should, so I checked iStat and it said that my battery life is at 86%. I also have a 12 inch powerbook G4 that still has the same battery it came with and the battery life is also 86% and it is more than five years old. Is this normal for the Macbook Air or should I take it into Apple?

I have a quick question about the battery in early 2008 MBP. The laptop is 13 months old, with 273 load cycles, and it is already down to 72% of original capacity. I've read that it should still have 80% at 300 cycles. Is this normal, or is the battery dying faster than it should? I don't suppose there's anything I can do short of buying a new battery right??

Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off.

I got my MacBook Pro on the 1st of September and I'm a bit worried about the battery life. At the moment the screen brightness is one bar and bluetooth is off, which is how I normally have it and the battery life time estimate keeps changing quite a lot. 5 minutes ago it said 5:11 left, and since then it's changed to 7:30, 7:58 and now it's saying 6:50 and is now on 95% and 8:03. I'm not doing anything differently and I don't know why it's doing this.
