MacBook Pro :: Automatic Graphics Chips Switching - Extended Battery Life
Apr 13, 2010
the new machines will switch between graphics chips. all very nice (at last), but my 15" MBP 2.8 doesn't and it's a real pain for me as I often go between apps than need the extra speed and then back to e.g. Word, and could really do with the extended battery life (I have the old style battery pack) any news if the older graphics systems can be worked to switch on the fly...i.e. without having to logout and shut down all the open apps, and work?
I have a late-2010 Macbook Pro 15" and have been having issues with gaming. Specifically, the games will freeze the system requiring a reboot. After reading further, I learned about the "Automatic Graphics Switching" mode under "Energy Saver" in the System Preferences screen. Upon disabling this setting, and locking the preferences, the games are still freezing.
I have not re-enabled this setting but when I check the settings again it is enabled. Seemingly, the OS is changing the "Automatic Graphics Switching" on its own.
I have a recurring problem where my screen (built in or external monitor/projector) will just go blank at random times. It is an unrecoverable situation and I have to do a hard power reset to get working again.
After testing several theories without success I struck upon one that showed promise. The blanking tended to occur when I was in Lion Fullscreen mode, or using a gesture to start expose - so I figured maybe it was a graphics switching issue.
So I went into System Preferences and disabled 'Automatic graphics switching'. I then ran trouble free for several days (I was typically crashing 1-2 times a day)
Then several days later it happened again and I thought I was back to square one. However, a colleague suggested I check the graphic switching setting to see if something had changed it back, and sure enough it was re-enabled.
Now I find myself in a constant battle with the system to keep disabling the 'Automatic graphics switrhing' in System Preferences.
I have tried setting it and locking it, but sooner or later it reverts. I need to know if it is possible to force it to stay disabled.

I have a MBP Classic (early 08) and I've noticed that the battery life seems to have dropped ever since I switched to SL. I should have conducted a more scientific experiment just before the switch, but I didn't, so I can't be sure. Is anyone else having a similar experience with Snow Leopard?
Just bought a new MBP Unibody and I'm loving it so far. My friend has the one with the single graphics card and he's claiming 6-7 hours of battery life on a single charge with the screen lit a little under half. I set mine the same way and I don't get as much battery life. I have the one with the dual video cards. Is that going to cause the battery to drain faster and if so, can I disable the second video card when I'm not doing intense graphics processing?
I have a unibody 15" macbook pro. I'll go into my energy saver. The "better battery life" box is checked. So I go ahead and check the "Better Performance" box. I log out, and log back in. I go to my graphics settings and the "Better Performance" box is checked, however it still says next to it - you must log out for the changes to take affect... funny since I just logged out. I tried doing an smc/pram/nvram reset... but nope
Just to prove the "better performance" isn't happening, I ran an xbench test before and after I logged out into the better performance modes. The graphics scores were pretty much exactly the same. Here's a post on the Apple forums w/ someone w/ the same problem.
This problem happens when I'm working between several applications at a time. I'm actively working in the current app when OSX automatically pulls me out and shows me something in a background app that suddenly requires attention, like a dialog box. Quite often I open or save files while working on something else, ususally in fullscreen mode. Moments later, I'm disruptively switched to a file that just opened in another application, or I'm told that something was saved, updated, installed, etc. This automatic switch interrupts my typing or commands in the app I was currently engaging, and has become a major problem.
Is there a way to keep OSX from pulling me out of my current application?
I generally keep 20 or so tabs open in my safari window. A month or so back, suddenly, each time I click over to a diffent tab the tab reloads. How do I stop this? And is this problem making my computer (fan or hard drive?) wind up for long periods of time? Sounds like a little jet engine about to overload.
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?
here we are with SnowLeopard 10.6.x and it still has no automatic shutting off laptop screen (Macbook Pro) when hooking up external monitor????Why do i have to close the lid, let my laptop go to sleep, wake it up, re-enter password, have my internet shut down and re-activate and all other processes just to shut down my MBP screen when hooked up to my cinema display???Hell even Windows Vista/ 7 does it automatically when i tested it via Bootcamp, requiring no closing of the lid or halting any processes or the internet.
I'm currently studying for the GRE, and here's my current setup.
Desktop #1: general computing
Desktop #2: vocabulary
Desktop #3: verbal
Desktop #4: math
1) I'll have a Chrome window open on #2 at a website to help me study vocabulary. However, when I'm at #1 and I click the Chrome icon in the dock to open a new browser to check email, it automatically takes me to desktop #2. While I can just check my email at #2, I want to keep that desktop exclusively for studying vocabulary. Is there any way to make MC treat each desktop as a separate desktop and NOT jump between desktops?
2) This seems to be a MS Office specific annoyance. I'll have a excel document open on #1 and #2. When I close the excel document on #1, MC automatically takes me to the document in #2, when I just wanted to close the #1 document and stay in #1.
3) A different scenario of the previous annoyance. There's an excel document open in #2 and I'm currently in #1. When I open an excel document MC...
- takes me to the ALREADY opened document in #2
- opens the document I wanted, but places it in #1
so that I'm in the wrong space AND not even looking at the document I just opened.
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.
The title is pretty simple, and self explanatory. Will the HD Graphics/330M combo, or the 9400M/9600M GT ever be able to switch back and forth in Windows? And regardless of if it's possible, what is the limitation, drivers, other software, or a physical hardware limitation? It would be a nice way to get more battery life out of Bootcamp.
MPBr, 15", Early 2013 with dual graphics (Intel HD Graphics and AMD Radeon)
Running Maverics 10.9.3
What is happening:
1. Machine doesn't switch to AMD graphics no matter whatever app is running. In activity monitor even if some apps say "Requires High Perf GPU", the graphics card being used is still "Integrated".
2. Connecting to an external display via thunderbolt or HDMI doesn't work (external display doesn't turn on) either as it required discrete graphics too.
3. After a reboot (at what time I believe machine tries to use discrete graphics card), the display is always blank. Even the Apple logo on back of lid is turned off. Only way to get the display back is to close the lid and open it after 10 ~ 15 seconds at which time it probably switch back to integrated and comes alive.
What I have tried:
1. Reset PRAM. 2. Reset SMC. 3. Tried gfxCardStatus [URL] to no avail. If I manually switch to discrete card, gfxCardStatus checkmark say it has switched, but it doesn't. 4. Tried booting into hardware diagnosis (pressing D while booting) but was unable to get the screen turned on to proceed.
Does anybody experience any delays with the auto graphics switching on the late 2010 MBPs? I mean serious delays? Mine seems to be very slow at making the switch. Say if I open a PDF that has a load of images in and start to scroll at high speed to scan the document, everything becomes very stuttery. Then, after a while (very random in how long it takes) everything starts to get smoother, when I assume the NVIDIA kicks in. I thought this was meant to be more-or-less instantaneous?
My primary concern is whether or not uMBP users will ever be able to switch the graphics cards without logging out every time? I remember hearing that it was a software issue, does that mean that it might be supported in Snow Leopard?
Obviously the new Macbook Pros do not require a reboot to switch between graphics cards while the previous generation, the one which had two graphics cards made by the same company, requires a login/logout. The case made for the necessity of this login/logout has been the need for the WindowServer process to be relaunched, and to overcome this, WindowServer would need to be rewritten. Obviously that didn't happen. Further, if random Nvidia insiders are to be believed, this wasn't done using Optimus technology by Nvidia, but rather by Apple... so. How do you suppose they pulled that off?
I just plugged in my Cinema Display to my MBP for the first time, and for a while couldn't figure out why the heck the computer wasn't recognizing it (though maybe I'd gotten a bad MDP/DVI adaptor).
Then I'd noticed I'd set it via gfxCardStatus to use Intel graphics only. I released it to Dynamic -- and voila! Display recognized. Interestingly, it now also will not accept being set back to Intel only with the monitor connected.
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.

I purchased a Macbook Pro 15" i7 last month, and since doing the migration (using the migration utility) from my old black macbook my graphics are stuck on the Nvidia graphics and is not switching to the Intel HD graphics. This is eating battery power like no tomorrow.
See the new Macbook Pro that I recently got has two graphics cards. One, the integrated, standard issue Intel HD4000 and the other one, a Nvidea GT650M. Personally, I was thrilled to learn this. However, my Macbook Pro seems to switch in between these two and I really don't want it to do that. I would rather just make the GT 650M the main graphics card and avoid using the integrated graphics.
"Does it harm the battery or reduce battery life, to use the AC adaptor for extended periods while the battery is fully charged?"Someone answered, "I would have to disagree with the others who say that it hurts your battery & reduces battery life by keeping your AC adapter plugged in with a full battery.I have done extensive research and asked many apple employees and have always come to the same conclusion. They all say to keep your laptop plugged into an power supply whenever possible. Only use your battery if you have to, in those times when you are not near a power supply.
