MacBook :: Advice On Macbook Running On Battery Only?
Mar 31, 2010
I've been offered a faulty Macbook (2ghz core 2 duo 120gig)I haven't seen it in the flesh yet, but the owner tells me it powers up on battery power, but will not charge one, nor run from the ac adapter.The owner bought a new battery and was able to run the Macbook while charge remained.I am a novice as far as Macs are concerned, but it sounds like a faulty ac adapter, or some issue with the mag port or internal electronics.Have any of you any advice on what this might be?I realise worst case senario it may need a logic board, so will be purchasing it with that in mind.
I recently bought a 15 inch Macbook pro (yes, excited since it replaced my 7 year old Pentium 3 desktop), and I am wondering what the proper way is to allow my battery to last as long as possible in the LONG RUN (in terms of changing the battery and it losing its capacity). For much of the time, I have access to a/c outlet, so should I just leave the it plugged in as much as possible? Or should I only plug it in when the battery is used up and take it out when the battery is full again?
I just turned on my 13" MBP and got this message. Apparently, this is supposed to come up when there is only like 5% charge left. My battery indicator at the top of the screen said there was 22% charge left. Also, according to IStat, my battery's health has already dropped down to 97% after only about 2 weeks and 5 cycles. Is this normal? I'm going to try recallibrating my battery by fully charging it and then letting it fully drain. Is there a good chance that this solves this problem?
my macbook pro not charging. the battery is running low on 20 percent i puted it on charging it says not charging and light in charger is green what the problem can be?
The battery icon on my macbook pro has a 'X' on top of it. The machine turns off as soon as i remove the power cable from the mac. It turns on only when i remove the battery and again put it back on. Once i do this, the battery shows 100%. After i leave it connected to the power for an hour or so, the 'X' appears again!! My macbook is not under warranty.
Its a 15 inch, Late 2008 model running on OS X 10.9.4.
I have a late 2007 MBP 15inch 2.33Ghz Core 2 Duo. I have had since new and no problems. Over this last week I have had the same issue a couple of times. The MBP just switches itself off. The first time it did it, it was running on battery (I was using Aperture) and had 60% power available. It would refuse to re-start until I connected it to the mains and then it ran fine.
Then it did the same thing overnight at some point. I had left it connected to the mains (as I always do at home), had shut the lid to put it into sleep mode. When I came back it was switched off. No-one had touched it whilst I was away but yet it had just turned itself off.The only thing that I noticed was that when I started it up both times the little light on the magsafe connecter kept flashing between orange and green. However when the computer booted into OS X both times it showed a reasonable amount of power in the battery.
if I'm going to be running windows 7 through bootcamp almost full time.. would it better to get the 15" with 9400m only since the other models I've heard default to 9600 under windows. I don't play games and want to have good battery life while using windows.. so does the 15" w/ 9400m only seem like the better option for this?
I have a MacBook (purchased in May) that has issues with the battery status. When the MagSafe Adapter is plugged in, it shows that the battery is charging, but when the MagSafe Adapter is unplugged from the computer, the computer does not recognize that it is running on battery power. (It still shows that it is running on A/C power.) I have already reset the System Management Controller, and it didn't work. What else can I do?
I just got the replacement battery from Ebay seller from China claiming it is the genuine battery. I am using it right now, when I plug the ac connector it doesn't turn red to show me that it is charging or something also the battery icon is showing an X but the battery is still running. I paid $60 for it.
My last battery popped, and on Monday, Apple store gave me a new one. The lady told me that it was best not to keep the power connected all the time. So I charged it to 100% and pulled the plug. It runs down incredibly fast. This morning it's been unplugged for almost an hour, doing just a bunch of web searches, and it's already down to 37%. This isn't normal, is it? I was able to watch a 2 hour movie on a full charge for my old battery. Does the charge get better over time?
What is the battery life like running on windows 7? I'm going to primarily use the an air under windows but will it really lower the battery life? Can't seem to find this info in any of the reviews so far.
I am not sure if it only my macbook, but I notice a slight performance drop when I run on the battery v the AC. I notice that my application load slower, folders open slower and expose and spaces response is also slow as well.
2010 MBP 15" i5 running 10.6.3. Time machine doesn't seem to care about the fact that the notebook is running on battery power. I keeps on performing backups. I've tried restarting, enabling and disabling Time Machine....nothing seems to work... Isn't time machine supposed to delay backups when the laptop is on battery power..?
The last couple of days my battery has been draining extremely quickly, at full charge it indicates that I will get about 2 hours battery life when previously I was getting 6 to 7 depending on what I was doing. Also, I have noticed that the fan is running almost constantly and at high. I'm running os x lion and this is a late 2011 model MBP 13".Â
I have a Lion-native early 2011 13-inch MacBook Pro aluminum unibody running 10.7.3.I was using it an hour and a half ago.I closed the lid, and when I came back to it an hour later, the battery had died.Plugging in to a charger did not wake it.I force shut it down by holding command+option+control+shift and the power button.Now, when I turn it on, I see the white screen for a half second, then it fades to black.The indicator light stays on and solid (not pulsating).I have tried:
- Resetting the PMU
- Resetting the PRAM (white screen for half second, then fades to black, each time)
- Booting to Single User (white, then fades to black)
- Booting to Recovery Mode (white, then fades to black)
I have tried to provide all the pertinent details as well as what I have tried.Please let me know if you need more information.
Info: MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)
I have Mac pro about two months old. I am having problem with my Mac pro When I remove the betray charger, system running very slow and when I cannot charger it will run normal.

I recently did a Lion clean install and since then im having this wierd issue..I already saw some cases that the kernel_task was eating too much cpu but that was random and caused by flash player.. mine is different.. it only happens when i have less than 5% battery and it stops when i connect the magsafe. I already tried PRAM reset.. already tried uninstall flash player but with no luck. What can i do ?Â
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. Â 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.Â
Just did the latest Mac software update a few days ago and noticed that my MBA runs hotter (fans are constantly screaming) and the battery life now is about 1:15 hours on a full charge versus 3:30 hours before. Anyone else experiencing the same issue?
I am looking into a new computer, I was full force ahead toward a mac until a friend told me a couple of concerns. He told me that he has heard about macs being kind of glitchy and somewhat touchy. Things like leaving it in the car for even short periods of time or banging it around in a laptop case will cause problems. I am not crazy rough with my computer, I mean hell, I made a Dell last me 5 years before having to get the another one, but I need something that can take the occasional mis-judgment. I also want some advice on what kind of specs I should have. I am looking at doing Grad school via distance education and need a computer that will provide the ease of doing things like a virtual class room with little to no problem and of course a good paper writing program.
I currently have a PowerBook G4 1.67GHz, 90GB HD, 1GB DDr SDRAM... it's ok, but is now getting slightly outdated. Converting takes FOREVER, programs are slow and often crash, I'm nearly out of hdd space and I can't use new application as some require Intel.
So with Apples announcement of the new 'updates' to the MacBooks and the MacBook Pros, I am really torn on which one to get. My initial thought was MBP but then MacRumors posted information about the Montevina Centrino 2 due in June, and then all the speculation started about the next MacBook and Pros Revisions.
It must have been this time a couple of years ago, and I bought my PowerBook, and then a few months down the line the transition to Intel began...
What do I go for? A MacBook (2.4GH White) or do I just go ahead and get a MacBook Pro (2.5GH 15")?
I really feel like I'm downgrading if I go for a MacBook.
When I got my first mac it shouldn't have been a PowerBook, I should have went for the iBook (is that what it was called?)
For the last 4 Months, all I've used my PB for is: writing with Word and Final Draft, iTunes (movie, music, tv shows), converting for itunes, e-mail, internet, and Adium (chatting). I'd like to start a website showcasing my University Media work.
This is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).
I have a quick question relating to MacBook gaming: My old HD was way too small, so I bought a 320GB to replace it. I'll be doing a clean install soon. I also have an old copy of XP that I got ages ago and never used. I'm hoping the activation key still works...
Anyway, back in the day, I used to play Quake II and III a lot, as well as some other games. I think I still have the disks somewhere. I really liked Quake II, and would like to go through it again. Plus, I'm sure there are some other vintage (QII was '97!) games I could play.
My MacBook is the first Core 2 Duo model, with 2 GB of RAM and, I guess, the 950 integrated graphics. The PC I used to use for QII was a P2 450 MHz with a Voodoo GPU, so I *think* it should be no sweat for the Macbook, even with the crappy integrated graphics.... Heck, it seems some netbooks will run these old games.
Anyone done this? I don't want to go through the hassle of partitioning and installing XP if it's pointless.
'm not particularly fond of some of the commercial macbook skins out there, so i'm interested in creating my own.
i'd like to create something similar to this:
clearly, there's some sort of custom/created skin (vinyl, perhaps?) on top of the actual macbook without covering the macintosh light. on top of that is a black incase cover.
any tips on creating something along these lines? methods/tools/supplies?
I will be purchasing my first Mac within the next few weeks, It is the 2.22ghz Intel Core 2 Duo version. My questions are as follows...
I will be playing a fair amount of games, and intend to use Windows on Boot Camp.
1. How do the games play on my system when using Bootcamp? GTA IV, Fallout Bio Shock etc 2. What Windows is best to install on Bootcamp? 3. Do you have to go through Mac OS access Bootcamp and then go onto Windows or is there an option to chose your OS upon booting the Laptop up 4. I intend to use an external HDD for time machine but also intend to use it for backing up Windows Stuff. Is there a magic or specific way of going about this?
I'm fairly new to Mac's and have had this 13" MBP since July of 2009. I've noticed that my laptop will display a black screen and will not respond until I hold the power button and then restart it. Last week I sent it to Apple repair which they had it for a week and could not duplicate the problem. So it was sent back to me un-repaired. I honestly feel as though there is something wrong because at first I thought it wasn't waking up from sleep mode. However since getting the laptop back on Friday I have be paying attention to what's going on.
Since I thought it was a sleep issue, I thought if I went into the System Preferences, Energy Saver and from there I changed both the Battery & Power Adapter settings to NEVER, to keep it from going into Sleep Mode. Well after a little while the laptop will go to the black screen like I've been experiencing but why is the screen going black if I don't have it set to ever going to sleep?
