lately I have noticed that even though I close the lid on my macbook pro, the battery continues to drain and it is very hard to wake it. I have to restart it several times to get to to open properbly.

I had my MBA rev B turned of for 3-4 weeks and when I turned it on today it was at 40% power. Is that normal that it to loose that much battery when turned off, are you seeing the same number? I know when in sleep mode that there is a pretty high loss even over night but turned off I thought it was minimal.
Seems higher than my previous Mac laptops.
I'm wondering, what is better for prolonging your macbook pro's battery life, is it
1. drain the battery, recharge it fully, plug out the source, drain it, and recharge it again
or
2. keep charging it whenever you have a power source and never drain it?
I've always been doing #2 because I use the laptop a lot and home and it would just be a hassle to keep switching the power source on and off.
But then I heard that it's bad if you overcharge your battery, so once in awhile I try to do #1. Last night, though, my friend told me it's bad for your battery if you drain it all the time.
So which is, in fact, good or bad for your mbp?
I recall reading that if I keep my MBP plugged to the wall all the time ( I do), I should drain the battery to about 50% every 2-3 days, to keep the battery's juices flowing.
Personally I don't have the patience to do this all the time. Is this step really that important?
What are your thoughts?
My MacBook shuts down when the battery drains all the way down. I'm pretty sure back in the days of PPC lappies, they went to sleep before the battery died. Is it supposed to shut down, or is something goofed?

View 24 Replies View RelatedWith mine, when I drain it completely, it just shuts down, i.e. it doesnt go to sleep mode as there is no pulsating light on the front right corner. Once I start charging, however, and I can again switch it on, it resumes where I left off, so the computer has saved the contents of the memory onto the hard disk. On my SR MBP it was different, it would actually go to sleep mode when the batteries were almost completely drained.

All i did was some web browsing and about half an hour of video chatting on ichat. My brightness is at halfway.
is this normal drain? the specs say 10 hours, but when i first got it it lived for about 6 hours, which was plenty for me.
i've noticed recently that my battery has been acting funny, i'm thinking it may be because of my heavy audio work with garage band and reason.
the app coconut battery says my battery capacity is at 94% so I'm not sure what the problem is.
I've had this laptop for about 3 months, and i've properly calibrated it twice.
I have a 2010 13" MBP that will shut itself off instead of going to sleep when the battery is drained. I tried recalibrating and resetting the SMC, as well as disabling hibernate, but the same thing happens. The computer is barely a month old. Anybody else with a 13" experiencing this? I posted this issue on the Apple forums and someone replied stating that they heard Apple is looking into it, but usually occurs with i5 and i7 machines.

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!
I looked around and I find varying opinions. My laptop is mostly at home. Should I keep it plugged in when its full or should I let it drain? Please explain too.
Also, coconutBattery says I've used five cycles even though none of those were complete cycles. Is it just problems with the software or does it really count as a complete cycle?
I’m hoping someone can help me troubleshoot some strange behaviour of my Macbook Pro4.1. It’s an early 2008 2.4Ghz Core 2 Duo. I’ve had this running perfectly for the past 2 months with an Apple 65W Magsafe Adaptor, although I recently got an 85w version so I’ve started using that for a bit. I recently read somewhere that it’s good to allow the battery run completely flat once a month or so, so I unplugged the adaptor last week and ran it off the battery for the afternoon. When it was almost done (10% charge left) I went for a shower and came back to find the Macbook powered down. I plugged in the Adaptor back in but I couldn’t get it to start. Â
I have to say at this point, that my 85w adaptor sometimes needs a wiggle at the magsafe end to get it to work. Despite this though I couldnât get the green power LED to light or the Macbook to boot up. I then tried my 65W adaptor, which is perfect, and although the LED lights up (first green and then amber) the macbook just doesnt power up with it. I tried the 85w one again the following day after leaving the macbook disconnected and battery removed overnight, and was pleased to find that it finally booted. Amazingly, despite having no power at all for the whole night it came back with all my applications running, safari tabs and the documents open! Anyway, I noticed from the menu bar that the battery was not charging and I couldnt seem to get it to charge. I ran it all day and the system profile showed that the Battery was about half full and had a ˜normal condition with about 187 charge cycles. However I cant run the Macbook off the battery. When the power cuts out from the 85w adaptor the whole macbook shuts down. The battery isn’t doing anything, even after charging all day and being half charged. What’s more neither of my 65w adaptors can start the macbook no matter how many times I try them. Only my 85w one can boot it, but it’s defective so very rarely seems to work. The 65W ones worked perfectly before,so I don’t know what’s changed.Â
I read the Apple guide to resetting the SMC and have now followed the procedure several times, but it hasn’t helped. I cannot boot the Mac any more. Does this Macbook come with an 85w adaptor or 65w? I’m confused because the 65w ones always worked until now. Also, the battery itself is only 60w. I’m going to purchase another 85w Adaptor, in the meantime any advice would be very welcome.
So when I charge my macbook pro retina display too a 100% and then when I come back the next day and turn it on the battery has drained by itself by like 7%. Sometimes they are even drastic changes like 15-20%? I have just bought this macbook and is only a week and a half old? What should I do?

I have a sleep problem with my MacBook (9400M White). I recently resolved a problem where it wouldn't go to sleep by itself if left inactive on battery power (regardless of energy settings) by resetting the SMC and PRAM/NVRAM but now something else has popped up. Now, whenever I cycle my battery down to past the low battery warning popup, it just eventually completely dies. Shouldn't it go to sleep first? That's what my old iBook G4 would do. I doubt it's something related to the SMC or PRAM/NVRAM since I just reset those. What else can I do? I'm pretty sure my MacBook should still have enough juice go to sleep.
View 8 Replies View RelatedIs it better, during normal usage, for example at home, where you could either charge your MacBook Pro or let the battery drain until it is used up (5%, ...).
Some people say that letting the battery cycle is the best option, yet other people, including my friend who had lost many many cycles even though he had attempted precautions (Dim screen brightness until one block remained, wireless off, bluetooth off) had said that having your laptop plugged in as muchas possible is the best option, as there would be no cycle change.
When I close the lid on my MacBook Pro (Late 2008), the battery drains almost completely over a night or so! Very odd. Anyone else dealing with this? I reset the PRAM already.

Before some days I noticed that Snow Leopard installed its update 10.6.4.
Well no big problem but I have a sense that the time remaining without using AC adapter has slightly fell. Before, using only firefox for example I could see about 6 hours remaining (some minutes after powering on my mac). Now it hardly shows about 4+.
Has any other noticed that?
I Have an October 2008 Macbook Unibody 13.3 and after installing Lion the CPU fan stays permanently on and the battery drains in 2 hours. What can I do to fix this?

Last night I had a weird experience with my mid-2011 MacBook Pro; I went out to dinner and came back to find the cat had kicked the power cord out, draining the battery. I've had this happen before and wasn't too worried; it's always just restarted after I plugged it back in. This time, however, I plugged it in (getting, perplexingly, a green light on the cord) and nothing happened except for the sleep light slowly flashing; it didn't respond to any pressing on the power button, and the sleep light disappeared if I unplugged the cord. The battery test button on the side got one flashing light (meaning, I believe, a dead battery), which also didn't work if the computer was unplugged.
I left it plugged in while I hunted for info on the problem and about an hour later had just decided that I was going to have to take it in to the Genius Bar when it suddenly booted up. The cord light turned orange and it proceeded to fully recharge over the next two hours. Is this normal behavior after a battery drain? Should I be concerned? Is it worth taking the computer in to get the battery checked, or some other element of the comp? (some of the things I looked at were talking about the logic board, which is not a happy thought) iStat Pro claims the battery is at 41% health, 111 cycles, which I would think would mean it has some life in it yet.

I keep seeing different anecdotes about people having lagging issues with the Intel HD graphics card. Is it really that bad? It would be a real pain to have to keep it on the nVidia card all the time, even when unplugged. I'm afraid that it will really drain the battery a lot faster than having the Intel on. Anyone have any estimates of this? It's one of the more worrying things about the Pro.
View 24 Replies View RelatedAfter discovering that the Tweetie app I use turns on the discrete GPU, I've been looking at alternatives to maximize battery life. A lot of twitter clients use Adobe Air, which also seems to get a bad rep, but is that because it drains battery life too, or because it's just buggy otherwise? So far I've been using twhirl without any obvious issues, and I'm testing out the battery usage with that running. I have to admit, I didn't notice any significant battery drain when Tweetie was running, so maybe I'm just overreacting here. If I remember right I got a little over 6 hours, and installed Tweetie about two hours after I turned my MacBook on then. I'd actually prefer twhirl since I use that on the desktop and I'm just used to it, but not if Adobe Air is going to cause problems on my shiny new MacBook.

View 4 Replies View RelatedI did some google searches, but could not find anything that was exactly my issue. I have a 2008 MBP unibody. If the MBP is on battery only and I close the lid, the notebook shuts down completely. This is even when the battery is fully charged. However if while plugged in and I do the same, the computer "sleeps" as advertised. I have reset both the SMC and PRAM to no avail. The main thing that bothers me is it seems like when this happens on battery, its almost as if the computer is getting a hard shut down. The machine acts as if the battery was pulled while the lid was closed and this is obviously not good for the hardware or sofware.

I just bought a new MacBook Pro with a solid state (flash memory) disk. The battery life is good while I'm using it, but if I leave it with the cover off for a few days (asleep, I assume), it'll be mostly discharged when I open it up. I assume this isn't normal - it shouldn't be losing that much charge when closed and hibernating. I don't have "wake for ethernet access" checked, if that makes a difference. What's going on - why won't it hibernate?
View 9 Replies View RelatedI have an 13" MBP that I ordered new in April, 2012. It is running Lion. I have an external monitor that is capable of 1440x900 resolution. I have an external keyboard and trackpad hooked up, and I like to close my MBP up and stick it in a BookArc. I want to be able to have the internal display disabled and to have the MBP only allow me to put windows on the external display, so long as the lid is closed. I also want to be sure that I am taking advantage of the resolutions available on my external monitor, which are higher than those supported by the internal display (specifically 1440x900).Â
This doesn't seem to work because I either have to allow the MBP to continue to draw my desktop across both screens (internal and external), OR use the "mirror displays" mode, which restricts my resolution of my external monitor. This means I either forgoe the additional resolution benefits of my external monitor, or I end up with windows that fall off-the-cliff, so to speak, because they are drawn in the portion of the desktop that would be shown on my internal display (which is closed).Â
I've read the community support pages on using the MBP with an external monitor, most relevantly, this page. It simply recommends using the "mirror displays" option. However, this option, as I mentioned above, doesn't allow me to make use of the additional resolution, and my external display looks bad. how to keep the 13" MBP in closed clamshell position, with the internal display disabled, and use my external monitor at resolutions higher than those allowed by the 13" MBP but which are available to my external monitor when not in "mirror displays" mode?
