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?
View 5 RepliesApple 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.

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?

View 3 Replies View RelatedI 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.
View 7 Replies View RelatedWhat 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.

View 7 Replies View RelatedI 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?
Point 4. Says the computer will automatically go to sleep and then point 5. Says I should turn of the computer. Isn't it the same of the computer stays in the sleep mode?

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.

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?

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).

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.
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.
View 1 Replies View RelatedI have had my MacBook Pro now for a little over 2 yrs and I was very frustrated I could not change any print options in any application. I know that the Triangle button expands print options screen but when I do, I have only two print choices. It gave me Standard or Page Attributes in Office and any other App it is Standard and Last used settings. I can't print in Draft, Best or other setting because it does not even give them as a choice. I have two high end color photo printers, Canon i9900 and Epson Photo series and an old HP830 series. Any app I tried to print from and the same thing. I tried to capture the options on the choices but it would not grab that part of the image but here is my screen shot. I searched many forums and I still get the same answer so something else is not letting me change things so I figured best to ask since I am a 20 year win user now switched to Mac. Well right after I posted this question, my wife found the answer. I never though to check the application NAME in the print setting screen. Example, in the screenshot I am using Preview. I never thought to hit the up/down arrow next to the Preview label and wouldn't you know, that is were the quality and several other settings were. I felt pretty stupid that it took 2 years to figure this out but if I posted the answer maybe someone else will not have to take as long as I did to change their print quality!
View 1 Replies View RelatedI 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 have removed the (New) Battery and checked the voltage and it reads 3.6 Volts, I haven't checked this under load though, so presuming that the battery is OK, what else could cause this.. a failing System Board?
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?

For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!
