I have a unibody macbook pro 15 inch, 2.8 Ghz, 4gb ram, 500Gb HDD. There are various display settings like 1440x900, 1344x840, 1280x800, 1024x768 and so on till 640x480 (descending order). Will the battery consumption vary at different display settings? If so, how much of a difference will it make?
View 3 RepliesRecently my battery seems to be draining faster than ever before. I'm not sure why. I haven't changed any "display" settings & it's on default settings for brightness settings, etc.

Getting fustrated with my Macbook Pro 15''. Could never get battery to last more than 5-6 hours. This is the MAX i can achieve, with great pains to enhance battery life.
Argh, what's wrong with my Macbook Pro?
Check out the amperage drain. At this rate the Macbook Pro wouldn't last more than 5 hours. This is with half brightness, only finder and Chrome open, and the battery recently calibrated.
The amperage drain increases to -1400+ when i have more tabs open, and a few other apps.
However there was this ONE RARE OCCASION, where my Macbook Pro would only drain between -700 to -800 amperage. This was in normal usage and the battery easily lasted closer to 8 hours. But somehow, i can never replicate this anymore!
we all know flash is a battery eater so to prevent this is install click to flash then it will indicate every pages that runs flash has this word "flash" on webpage which is good thing.now, i am a netflix subscriber and to watch movies you have to install microsoft silverlight..i dont have any choice to install it. if i open a webpage for example cnn.com yahoo.com etc.. how can i determine that those sites are using silverlight?i believe silverlight will cause battery consumption like flash right?
View 13 Replies View RelatedSo I have a late 2008 MBP and the battery is draining way faster than it should. Coconut battery says that my battery capacity is at 93% and it only has 73 cycles but the battery has only been lasting 3 hours at best with a full charge, but most typically, it only lasts 2 hours while using the 9400m GPU and at idle. I have reset the battery per apple's instructions 2 times now and I have reset the SMC multiple times. this is what the system profiler says about my power capacity and consumption:

This all happened out of nowhere one day, I used to get a solid 5 hours on each charge a month ago and now this.
Is there a difference in using mbp with a headphone or built-in speakers in terms of battery consumption?
View 2 Replies View RelatedTwo quick questions:
- Is it bad to have the keyboard backlight always on? Will it somehow burn out the little lights?
- How much less battery power will I lose if I have the backlight always on? (I use Labtick).
I was using my MBP when I noticed that the display (the built in one) looked a little washed out. To make sure my color profile was set to the correct one, I opened up the display panel in System Preferences. The moment I opened it, the display snapped back to its regular appearance. As far as I can tell, it goes into the washed out version after going to screensaver and coming back, and going into display prefs is the only way to restore it. Anyone seen this before or know how to keep it from doing this?
View 2 Replies View Relatedi 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?

View 2 Replies View RelatedI was wondering if anyone knows of other ways to control the computer to preserve battery life. I'm thinking mostly about underclocking the cpu. Does anyone know if this is possible and also if this would benefit the battery life? I'm on Aluminum Macbook OS X 10.5.8.
View 8 Replies View RelatedI have the screen as dim as it can get. All I'm on is Airport with nothing else really going on and my battery life is only about 3 hours.
It used to be somewhere like 7 hours when I did this.... any idea if something could be wrong?
Coconut says I have 96% capacity left...
A little while later I notice the MBP felt like it was running when I touched it. It was vibrating from the HD running. I didn't think much of this.
I just now tried to turn my MBP on and it wouldn't. I decide to plug it in. When it turned on it did so for about 2 seconds, turned off, then turned back on. It then took a long time to boot up. When it finally did boot, it told me that the clock was all out of whack and I noticed tons of my settings had been reverted to default. I then check the battery to see that it is charging but the level is at 1%! When I shut the MBP lid earlier to put it to sleep the battery was at least 50%.
Whenever my Macbook powers down to 0 battery life and reboots from a new charge, I loose all my software settings, including browser cache, adobe settings etc. It's really annoying. I have a brand new MacBook Pro 15" 2.2Ghz i7.I'm running OSX 10.6.8 on it (I reverted because I didn't like Lion).

A friend did something that changed the display on my Macbook Pro. The background is weird and distorted and seems to be out of focus. I want to restore factory settings but without the trouble of reinstalling all of the programs. Can it be done and if so, how? I will watch for a reply.

I have a Vizio 22" HD monitor and it works great at 1680x1024 but don't know how to get those settings into my Macbook.
I have it hooked up via Mini-DVI to HDMI and the color is great, just wish I could get better settings. Seems like I am stuck with 1280x1024 else they are all interlaced and look like *****.

With the new MBP-R, I find that I am changing display settings, depending on the program I am using. Is there an option to have the display settings on the menu bar (I can't find it) or a short cut key, or a 3rd party program that does that?

I have a rev. A MBA and it does two odd things. If I set the display to full brightness, then power down and back up, the display doesn't return to full brightness. I have to go into the display preferences pane and move the slider a fraction of an inch to return to full brightness. The "adjust brightness for ambient light" and "reduce brightness on this power source" are disabled, so that isn't it. Also, the MBA forgets the brightness setting for the keyboard when it is powered off and then on again. As best I can determine the keyboard brightness is set to a random level at power up. I've used MacBook Pros for years, so I don't think it's anything I'm doing.

View 4 Replies View RelatedI've connected up my external monitor, which is a bigger Samsung 1600x900 and and I'm having some issues.. I'm trying to get the MacBook to recognize the Samsung when I plug it in and automatically adjust the settings, so I don't have to muck around with the settings every-time. Is there anyway of doing this? oh and disabling the MacBook's display so it doesn't detect it as a second monitor?

I've noticed that my macbook pro has been using a lot of RAM. I haven't really witnessed a slowdown on my computer b/c of any sort of shortage of RAM but I was just curious if this was typical (since this is my first mac). I have 4 GB of RAM and I often find myself with around 1-1.5 GB of free + inactive RAM. I had a linux system with 3 GB RAM before and it used between 1-1.8 GB of RAM and it seems like this system is using around 2.5-3 GB (active + wired). However, various OS X laptops in the past have functioned really well in the past with 2 GB and even 1 GB of RAM right? Is OS X just putting more processes in my RAM to speed up my system because more RAM is available OR does snow leopard just have high memory consumption?
