MacBook Pro :: Options To Quickly Discharge The Battery

Apr 22, 2010

I'm trying to calibrate the battery of my new MBP. I need to get the battery to fully discharge and sleep for five hours or more. What are some things I can do to get my battery to discharge more quickly? Do I need to tell the MBP to not go to sleep after 10 mins of non-use, or the battery might last through the night? Or is it just the display that sleeps? I'd like to be able to use my MBP in the morning, but I'd like to make sure I get at least the recommended 5 hours of dead battery.

How To Properly Charge / Discharge Macbook Air Battery

Jun 19, 2012

I want to know if leaving my Macbook Air charging 20/24 hours a day will decrease the battery's useful life? I like to use my external monitor and close the clamshell on the MBA, and the only way to do this is to connect the laptop's AC adapter. I also want to know if I should be discharging the battery completely once a week, as some Google searches have recommended? Basically, will the useful life diminish at a faster rate by not discharging the battery completely, and charging the battery constantly while the battery is at max capacity? I keep reading that with the newer lithium-ion batteries, it does not matter how the battery is charged, is this really true? I am concerned because the MBA battery cannot be easily replaced.

MacBook Pro :: Battery Maintenance (Full Recharge / Discharge)

Jan 1, 2009

I was wondering if doing a full charge and then a discharge is a good thing when a new mac or new battery is bought? Also should it just be a simple charge and discharge or does it have to be a full calibration? Also what is the best method in maintaining a healthy battery? Should I cycle at least once a week and do a calibration every few months? Or should one cycle per month be fine? Also is it alright if the battery is fully charged and I have the plug-adaptor plugged in to my MacBook Pro while using it? Finally, is it true that over night the plug or when not in use and not charging the plug should be outside of the MacBook Pro?

When starting up it must be connected to the charger and when i turn it on it makes the bing noise, goes to the apple screen with the wheel turning for a second and shuts off. I have to do this multiple times until it works. Another issue that I am having is that the battery is draining very quickly. I just had it replaced a couple months ago.

MacBook Pro :: Battery Healthy But Draining Quickly

Oct 23, 2010

I bought my Macbook Pro 13 inch last year in August. The health is on 88% with 84 cycles. Original battery capacity 5450 maH, current battery capacity 4809 mAH (Coconut and Istat Nano). I just read in another thread that there are users who have higher health capacity with many more cycles! I took it to the Mac store in Bangkok two weeks ago since I believe that my battery drains quickly. They run a test and told me that my battery is healthy. Then they also downloaded some updates for my Mac and run disk repair under disk utility. The technician told me that these are heavy programs and if they battery drains very quickly there is something wrong.

But according to him this was not the case. I have a 500 gb hdd and the technician said that since this is a big hdd (he recommended 320 gb maximum for 13 inch macbookpro), it will use more battery usage. I don't use heavy programs, only internet (Facebook, gmail, very seldom watch movies, watch news papers), Itunes and sometimes Word. I do a lot of photo processing, but this I always do with my adaptor plugged in. I think I can only use around 3 hours. Sometimes 4 hours. Screen around 80% brightness. Keyboard lights, bluetooth turned off. Do you think that there is a problem with my battery? Oh and I do calibrate my laptop monthly.

MacBook Pro :: Why Is Battery Dying So Quickly - It Has Only 94 Cycles

May 23, 2012

My MacBook Pro is 1 year old, almost to the day and my battery seems to be loosing all it's juice quite quickly these days. The battery cycle count is only 94. This morning I turned my computer on and I've only done emails. It's now about 4 hours since it's been on and I have 20% battery left. Bluetooth is turned off. Not doing anything any different than I used to. Seems to me the battery used to last 4 days for what I do with the computer. Now I charge it 2 or 3 times a day. I notice the underside of the laptop seems to get quite hot.

MacBook Pro :: Battery Power Drained Quickly And Unexpectedly

Feb 11, 2010

Earlier this morning, I was using battery power until the power drained quickly and unexpectedly. Once it shut down automatically, I could not turn it back on. It does not run on AC charge or battery. The mag-safe light is only a faint green, and I have reset my PMU. I'm hoping to not have to take it to Apple as it's warranty ran out about two months ago.

MacBook Pro :: Battery Seems To Lose Charge Quickly With New Mid-2012?

Jun 17, 2012

I recently was able to upgrade from a MacBook Pro Mid-2010 to a new MacBook Pro Mid-2012.  I've only been using the laptop a few days, but it seems like the battery goes down from 100% very quickly.  For example, right now I've only been using the computer for half an hour and the battery has gone from 100% to 71%.  I haven't been watching movies, etc., just browsing the web.

MacBook :: Dropped Battery Options With New Battery?

Dec 22, 2010

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.

MacBook Pro :: Mid-2010 17" MBP Options With Battery & Sleeping?

Jan 2, 2011

I recently purchased a 17" Mid-2010 MBP and put in 8GB and a OCZ Vertex 2 SSD drive. Ever since the upgrades and clean install of OS X, my system seems to not like to go to sleep when the battery gets low.Example, I was surfing the net earlier and the battery got down to 5% and I didn't get any type of warning that the battery was low. It went all the way down to 1% and then 0% and then just shut off instead of putting itself into sleep mode like it did before the harddrive and memory upgrade.

MacBook Air :: Temperature Fluctuates Quickly - Rev B?

Jun 16, 2009

I just ran a quicktime movie trailer and it immediately went to 81C. I have also noticed that the temp fluctuates very quickly, from 49C to 63C within 10 seconds when just surfing macrumors when I look at istat pro. So how hot does you MBA rev B get? Mine is a 1.86 SSD version and even though the enclosure doesn't get very hot stays in the low 30s I wonder if this is normal. temperature If I watch an episode of CSI Miami on cbs.com temp goes to 76C (176F) and fans go to 6200rpms. Enclosure still stays at 35C (95F). Is this what you get with the MBA rev B as well or is this something I should be concerned about and consider opening it to see the thermal paste and possibly re-apply?

MacBook Pro :: Screen Is Dimming And Brightening Quickly?

Aug 26, 2010

I just got a brand new MBP (6,2 and 10.6.4) but it's not my first. My previous MBP had the ambient light sensor that I could turn on and off via the system preferences (as mentioned in this thread) so suffice it to say, I know what it looks like when the screen dims and brightens. (I loved hovering my hands over the speakers. It was like magic to my PC friends.)

Now, I'm having an issue with my new MBP. I have my preferences set to adjust the brightness based on ambient light. And since the light sensor has moved to the microphone, it still does that just fine.

My problem is that I'm experiencing random flashes of the screen where it dims quite a bit rapidly but only for a short moment before returning to the original brightness. This occurs randomly in different light settings but most importantly when the light around me hasn't changed at all. And it has occured about once or twice a day for the last few days. I've even tried pressing my thumb over the light sensor really fast to see if it was the light sensor but try that and you'll see that it's actually really slow.

My other problem is that my screen is randomly resizing/zooming in on things. (I suspect this may be me doing some trackpad trick I'm unaware of but I've tried everything I can think of to replicate it and nothing works) Anyways, say I'm on my desktop and mousing over (with one finger) to open a folder or file. All of a sudden, all of the folders resize drastically. Or I'm in Firefox and a site loads. Then all of a sudden (*insert poltergeist*) the website zooms in or out. (like when you press cmd + or -) And it's always zooming in, never out.

Does anyone know what is going on with this? I don't know if the two things are related or if all of this is just really really stupid user error.

MacBook Pro :: Its Shutdown Quickly And There Is A White Screen Now

Jun 2, 2012

I went to a website yesterday, one that I go to every day, more than once. I was using Safari and saw a warning posted from the site owner about malware. It read this was happening with Chrome and Firefox. Everything was fine until I went back there maybe 15 minutes later and I got that warning page that he was talking about and now it was on Safari. You could click "ignore" or "continue" I think. I'm not sure cuz I don't remember. I thought it best to click out of the window. I opened a new window and a couple of weird things happened.  I was scrolling down the the "page down" key and it would not stop. Then the screen started slowly moving up to the top left and disappearing in the process. It was weird. I hit Safari and and it came back.  Then it seemed ok. I was as the library cuz I have no internet at home now. Then I went home and a little while later I was watching a download and all of a sudden it shut down quickly and the screen went white. The mouse was not "lit up", and I freaked - nothing worked - just a white screen. I did not know what was going on.

All I could think of to do was hold down the power button to turn it off. And I was afraid to do that - that it may never start up again. This morning I started it back up and the same thing happened. The start up sound lasted only a few seconds and then it was the white screen again. I looked at the battery underneath and all the battery lights were lit AND the power cord was plugged in. The light on the far left was blinking. I unplugged the power cord and the lights went off and then pushed in the button on the battery and all the lights went on for a few seconds like they are supposed to and then went off. My macbookpro was working fine and now it's not. It does not work at all. I'm using an older iBook and am at a local cafe wifi spot.

MacBook :: Sleep Light Flash Quickly On / Off At Startup?

Apr 20, 2009

Weeks back, had some blinds by my desk fall on my opened Macbook and strike right near the power button. No real physical damage, although the power button feels a tad stiffer when pressed. But since then, at start up, the sleep light will flash quickly off and on for a short burst, but then proceed with start up.

I've searched around the internets and seem to think that this might be a memory problem. But in most cases the computer won't start up at all. In my case the only indication I have of a problem is flashing sleep light at start up.
