17in MBP Freezes on Battery Power?

I have a 17 inch core-duo MacBook Pro running Mac OS X 10.4.9. Within the last couple of weeks (maybe since I updated to 10.4.9, can't really remember), I have been having an issue where whenever I take the computer off AC power and use it just on battery it randomly freezes after ten minutes or so. It doesn't seem to correlate to any specific task but it freezes to the point that apple control power button will not restart it so I have to hold down the power button until it shuts off..
The screen and clock go completely paused however iTunes music will still continue to play..
Does anyone have any thoughts on how to solve this via software? I already did an archive and install of the OS and am still having the same problems. I checked and repaired permissions/etc as well. I am not sure if this is related to hardware or software?
Any help would be appreciated!!!
Thanks again!

The first thing you can try is resetting the PRAM which is outlined here:
http://docs.info.apple.com/article.html?artnum=2238
If this doesn't help then try resetting the SMC:
http://docs.info.apple.com/article.html?artnum=303319
Read the info before resetting the SMC as it will return your MacBookPro to it's default settings.
If after all this you still get freezes you will have to call Applecare and they will probably ask you to perform the same tasks again.

[SOLVED] Thinkpad T510, freezes on battery power

My Thinkpad T510 will freeze after anything from a few seconds to a few minutes after boot. I cannot do anything except hard power off the laptop. Sometimes it freezes at the login screen, sometimes at the desktop. So far it hasn't frozen on boot. I'm using Gnome 3 and GDM. Laptop-mode which is enabled on battery and AC power. I'm using the nvidia graphics card with proprietary drivers.
I actually had a similar problem to this before, where it would freeze on battery power but much less often, usually anything from 10 minutes to hours after boot. It seemed like that problem had been fixed, but it has come back much, much worse.
I wonder if the updated Nvidia 302 drivers are to blame, but I have no idea how I might go about finding out.

EDIT: I found the laptop will still freeze once it had reached low battery power. To fix it properly, I backed up and then replaced the entire contents of /usr/lib/pm-utils/power.d/wireless with
#!/bin/sh
/sbin/iwconfig wlan0 power off
I ran the laptop down to critical battery level and had no freeze.
After hours of trawling Google, I *think* I've found a solution. At least it's been running for a good half hour now without freezing.
To fix, open up /usr/lib/pm-utils/power.d/wireless
Find the section -
case $1 in
true) wireless_powersave on ;;
false) wireless_powersave off ;;
*) exit $NA ;;
esac
and change it to -
case $1 in
true) wireless_powersave off ;;
false) wireless_powersave off ;;
*) exit $NA ;;
esac

Sudden shutdown of MBP while on battery power

I have started experiencing sudden shutdowns after being on battery power for 15 minutes. So far this has occurred while using Safari and Photoshop CS3. When I have checked the system log file, it has indicated "Previous shutdown cause: -103"
I have searched the web for this code and not found it yet - does anyone have an idea as to what this could refer to or what the issue might me? this is a 2008 MBP (purchased in August, 2008)

Those figures actually look fine, ze red baron.
At a maximum capacity of 5315mAh it is still at around 95% of original maximum capacity. Very different from what I expected when I wrote my earlier post!
It is possible that the figures are somewhat misleading if you haven't calibrated it in recent times, though. See http://support.apple.com/kb/HT1490 for the process.
You should also reset the SMC - see http://support.apple.com/kb/HT3964.
Remove and replace the battery, too.
I am wondering, though, if the battery is as good as the figures currently indicate, whether something else may be involved here. Has it ONLY shut down when using the programs you refer to, or is happening generally, regardless of what is running?

MBP Freezes after disconnecting power

After upgrading to Leopard whenever my computer is sleeping or closed and the power cord is disconnected the computer just crashes. When I try and wake it up all I get is a black screen with the rainbow colored spinning thing in the place of the mouse. The computer will just sit like this until the battery runs out or I restart it. Has anyone else had this problem or know what the issue might be?

Powerbook crashing on battery power after repair

I just performed a repair of my PB (replacing a screen hinge). It's okay, except that now it freezes on battery power.
The pattern is very strange: if I reboot with the battery, it makes it all the way to the login screen and freezes when I try to type.
If I unplug it while it is already booted then the screen dims (I have it set to do that on battery power) and then freezes a second or so later.
All activity ceases, the cursor becomes unresposive. It's not that the computer is not getting power: the screen stays lit, for example (and of course, it can boot all the way to login screen on battery power; it also can operate for quite a while in single user mode on battery power; I tried it long enough to fsck the disk).
The specific symptoms of the the problem are just so bizarre that I'd suspect a software problem if I hadn't just done this big repair. (By the way, I've repaired the disk (no problems) and, even though I think it's useless, I repaired permissions too, just for good measure; neither had any effect.)
Does anyone have any clue what I could have done to precipitate such a weird problem? Could there be some screw that is over- or under-tightened? A connector that is loose? Should I just take the thing apart again and put it back together again?

Well, the problem is solved, though the mystery remains. I carefully took the computer apart again and tested it after every piece was removed. It failed every time. Finally there was not enough left to actually boot. Then I reassembled it and, behold, it works!
I removed the keyboard, modem, airport card, fan connector, and PCMCIA cage and still had a crashing system. (I'd also removed and reconnected the battery cable, and moved the DIMMs around.)
So then I just finished the job. I disconnected the following from the logic board: hard drive, DVD drive, display, speakers/mic, power button (yeah, yeah, there's a few more I could have removed and kept a bootable system, but I was starting to get bored). Then I removed the logic board, looked at it stupidly, put it back, and reconnected all those connectors.
Then it worked. (So I put back all the other stuff, and it still works.)
So presumably one of those connectors was lose, or else the logic board was somehow incorrectly mounted.
I still don't really understand how a loose connector or incorrectly mounted logic board would lead to the symptoms I was seeing, so if anyone has a hypothesis, I'd love to hear about it.

Please help: My MBP freezes when not connected to a power supply.

When I am working on my MBP (specs below) without it connected to the power supply, it will freeze every once in a while. I have no option but to hold down the power button to do a hard restart – and then it takes a good five minutes to boot back up.
Does anyone know what the problem might be? It NEVER freezes when it is connected to power.
BTW – the MBP freezes randomly, *sometimes the battery will be near full, sometimes only half full,* so I don't think it has to do with the amount of power left in the battery.
Thanks in advance for any replies.

there is definitely a problem Apple must solve, i have this issue too.

MBP running out of battery power before sleeping - Help!

Hi
My MacBook Pro has been running out of battery power before the memory-saving sleep mode kicks in, so it dies with a little click of the HD. It's not a hibernation state as when I reattach the power supply it boots up a new session.
I've noticed this since upgrading to Snow Leopard last year, but put it down to an old battery that had 45% charge and wasn't powering the MBP properly. I now have a replacement A1175 5600mAh battery which is giving me 2-3hrs usage (which I'm pleased at), but now it still dies before sleeping!
I have tried to cycle the new battery, but can't. I have reset the SMC several times, with no effect.
I used to cycle the battery every week or two, running it down until it would no longer wake from sleep, recharge overnight etc, but now I can't do this because it will die before sleeping!
I've read quite a few articles over the net about this issue, but there seems like no cure. It's really annoying me now as I frequently work on the move and a dying MBP could potentially be disastrous.
Can anyone shed some light on this issue? Is there something I haven't tried yet? I think it's a late '06 MBP.

If you are not getting a warning, then there is something amiss with your battery. If a SMC reset and calibration does not fix the problem, then you may need to make an appointment at the genius bar and arrange to have your battery tested.
My old battery started doing the same thing--shutting down without warning. I replaced it, and the replacement battery started doing the exact same thing. I then returned the replacement, and the next replacement battery behaves in a normal fashion.
My first battery was worn out. My second battery was defective. My third battery is good.
Your battery should still be under warranty. Go back to where you got it and show them what it is doing and see if you can get a replacement.
Good luck!

MBP (13-inch, early 2011) goes into hibernation instead of safe sleep upon closing the lid (only when using battery power)

MBP details
13-inch MacBook Pro, early 2011 (model identifier: MacBookPro8,1)
Running Yosemite, OS X 10.10.1 (however, problem started while using Mavericks)
2.5 GHz Intel Core i5
4 GB memory
Symptoms
* the MBP goes into hibernation instead of sleep upon closing the lid on battery power (i.e., when AC adapter is NOT connected)
-- problem does not occur when AC adapter is connected
* putting the computer to sleep by other means does not induce the problem; these other means include:
-- [i] option+command+Power,
-- [ii] Apple Icon --> Sleep,
-- [iii] in Terminal: pmset sleepnow
* the battery is NOT getting drained at all; if I close the lid on 87%, the battery is still at about 87% when I get the MBP back up and running
To be as clear as possible:
(1) MBP is on and in use (power source: battery); battery is at X%
(2) the lid is then closed
(3) the battery indicator light glows bright for about 10 seconds, then shuts off, and with it so does the MBP (all fans and sounds cease)
(4) opening the lid and pressing any key on the keyboard does nothing (the computer is not sleeping)
(5) to turn the MBP back on, I must hit the power button once; this brings up and the gray screen and loading bar indicative of returning from hibernation
(6) log in; battery is still at X%
Attempted Solutions / Fixes
There are Apple Discussions addressing similar MBP issues, many of which at least have work-arounds, if not full-blown solutions. However, I have tried many of the proposed work-arounds and solutions; nothing has solved my problem. Such attempted solutions include:
* made sure EFI/SMC firmware was up to date
* updated all software
* logged in as a different user
* booted in Safe Mode
* reset the PRAM
* repaired disk permissions using Disk Utility
* repaired additional disk permissions in recovery mode (a la this chron.com advice)
* ran the Apple Hardware Test multiple times (short test while plugged in, short test on battery, extended test while plugged in, extended test on battery)
* booted from an external known-good OS on USB drive
* reseated the RAM
* used MemTest to test the RAM's health (it was good)
* tested my battery's health with the app Battery Health (it is healthy!)
* booted my computer with one stick of the MBP's original RAM at a time (figured "why not?")
* booted my computer using other sticks of RAM
* checked my power management settings using PMSET in the terminal (e.g., pmset -g); tried various hibernation modes (e.g., sudo pmset -a hibernationmode X, where X=0,1,3, etc)
* searched/grepped through my power management logs and Console messages to look for googleable items (e.g., pmset -g log | grep WORD, where WORD=failure, sleep, etc); still have not found help online
* brought the MBP to a Mac Genius
-- he ran some further tests, but found nothing;
-- he re-installed my OS as a hopeful-hail-mary-just-maybe-last-ditch effort; the problem persisted!
-- we both agreed that we had ruled out a software cause
-- he offered me to leave my MBP to get fixed for a flat fee of $300.00 (which after a couple weeks of trying to figure this out is starting to sound more and more reasonable)
Given that it is likely not a software issue, what hardware might it be? By booting from an OS on an external drive, I think I've ruled out a bad hard drive or hard drive cable. Also, given that inducing sleep in any way other than closing the MBP's lid does not cause the problem, it seems there might be a wire (or something) in the hinge section of the MBP that gets moved when the lid is closed possibly causing some kind of short circuit...or something.
If someone with more experience interpreting Console messages, for example, can help, I'd be happy to provide some logs, or any additional information.
Thank you for your time and consideration.

Ok, this is a crazy-simple, quasi-embarrassing fix, but I'll post it anyway just in case anyone is having a similar problem (for example, this guy: Changes to pmset being ignored).
Some time around late last August / early September (2014) this issue began happening for me (specifically, issue = closing lid while on battery power induces hibernation / shut down instead of sleep --- independent of hibernation mode). Maybe it was when I upgraded to Yosemite (not sure what the exact date of that was). As detailed in my original post, I frantically tried everything I could think of... At that time, however, I had quite a few presentations and posters to create and present at meetings and conferences, so I held off fixing it for a couple of months and returned to it this past week, where I tried a few more things listed above, but again to no avail...
This morning, I simply tried fudging around with all my power management settings again (via pmset in Terminal). The simplicity of the fix surprised me. But now that I understand it, I know it is likely the same fix for other threads I've read, such as the one above:
(TLDR in bold)
(1) Take note of your power management settings (Terminal: pmset -g custom)
(2) Is the "standby" flag set to 0? If so, set it to 1. Wa-la! Done.
This fix is crazy and embarrassing b/c I was so close to it for so long. I tried changing my hibernation modes multiple times (sudo pmset -a hibernatemode X, where X=0,1,3,25,etc). I read about manipulating other PMSET settings that helped other people with newer MBPs, like "autopoweroff" and "autopoweroffdelay" --- settings that I do not have on the MBP early 2011 (check your settings: pmset -g cap). And most amazingly of all, I even messed with the "standbydelay" setting, trying to make it so long that my computer should never go into hibernation... Yet, from what I can tell by looking over my notes, I never simply set "standby" from 0 to 1.
There are interesting questions that arise due to this fix. For example, why did this problem persist on clean installs of OS Yosemite? Is "standby" being set to 0 the Yosemite default? I'm not sure. If it is, then Kappy was right: this was normal behavior... It just wasn't always the normal behavior...at least not for my MBP. Normal behavior (hibernatemode 3) used to be (and now is again) that the MBP goes into safe sleep, and then only after an allotted amount of time will it go into full-blown hibernation.
NOTE: the "standby" and "standbydelay" PMSET settings are not available in some earlier MBP models (e.g., my brother has a 2010 and does not have these settings); so if you're having a similar problem with an earlier model, this fix might not be of any help to you.

Laptop freezes while on battery power.

I have Arch 64 bit install on a Thinkpad T510. While the laptop is plugged into power, it is rock solid and can run for days without a crash.
The laptop freezes up quite often when it is running on battery power. After anything from 15 minutes to an hour, it will probably freeze. I cannot switch to a tty, I just have to do a hard reset.

I'm not sure if tracker could be causing the problem, or if it is something else.
I have the discrete graphics card enabled - NVIDIA Corporation GT218 [NVS 3100M]

It might not necessarily be caused by loss of power, but maybe if the battery power dips? Or if the battery gets too hot and something overheats, then that could cause freezing. I'm only going by what I've found on google.
Anyway, I found another thread (not sure why I didn't see it before) that suggests that it might be caused by bluetooth (bluez specifically) https://bbs.archlinux.org/viewtopic.php?id=115814, but it seems like that was more of a locking up problem than freezing completely. I've remove bluez and disabled bluetooth for now anyway (unfortunately can't remove it completely because I'm on Gnome Shell) and I'll run on battery for a good while and see if things freeze again.
EDIT: also followed this - https://wiki.archlinux.org/index.php/HDAPS in case the problem was caused by the hard drive being moved about.

T43 Freezes only on New Battery Power

HI Gurus, I have a T43 1871 FU1 Model which is working fine so far. Recently my Original Battery is seems to be very weak, i thought to purchase a new battery. First tried with Lenovo, i heard that there are no battery replacements available for these models. Then i purchased an AGPTEK (Sanyo) Battery from Amazon.
Battery Details: Status : No Activity / Remaining Percentage : 100% / Remaining Capacity : 47.20Wh / Full Charge Capacity : 47.52Wh / Current: 0.00 A / Voltage : 12.39V / Wattage : - / Temperature : 22 c / Cycle Count : 1 / Manufacture Name : SANYO / Manufacture Date : 2010-09-19 / FRU Part Number : IBM-COMPATIBLE /Device Chemistry: Li-Ion / Design Capacity : 47.52Wh /Design Voltage : 10.80V
Problem: With AC Power system works perfectly fine. The Moment when i remove the power from AC and try to work with battery power "SYSTEM FREEZES" IMMEDIATELY.I tried to change batteries 3 times from the vendor.
I also updated the latest Bios - 1.29(70ET69WW) and tried with all other Power Scheme. I tried to search entire forums. With my Old Battery system works fine too. Also tried to diagnostics with Lenovo Toolbox, where test device functionality- Passed.
I appreciate any help to resolve my problem. Thank you

Hi and welcome to the forum!
As you can also see, the culprit is the aftermarket battery. These batteries are no good in my stance, and shouldn't be used. If I were you, I would return it and get a genuine from eBay or try to find one from the Marketplace of ThinkPads forum.
Hope this helps.

Does updating multiple apps on my MBP use a lot of battery power?

Tonight my MBP battery % dropped AFTER I updated seven iTunes apps, most being bug fixes. It went from 85% to 73% after the updates were completed. Earlier I was using my Beats Pill with NO drop. I had already put the Beats Pill off by the time I did the updates.
Do updates use THAT much battery power?

Do you mean Mac app store apps? Running Mavericks on a 2011 Macbook Pro should handle it fine, but it can depends on the type and size of the seven apps. It also depends on you wi-fi connection and your screen/keyboard brightness. Wi-fi updates can use a lot of battery because it's time consuming, especially if they're large files.

Ti 500 freezes while using battery power

My ti 500 freezes during start up whenever I start it up using the battery. If i start it up plugged in it works just fine, it will freeze once i go to battery power. I have replaced the battery device that plugs into the logic board. but the problem is still there. I recently replaced the screen taken from another ti 500. Any ideas what might be wrong? Any help would be great. thanks.-wam

I've had this happen with an old G3 Wallstreet 233 Powerbook some years back (hoping my memory is accurate) - - I think it had to do with the battery capacity wearing down with charge cycles - - I'm guessing your battery is at least 2.5-3 years old.
You might try calibrating your battery (battery-only full discharge to shut-down, then powering up on AC to full charge), I've heard some folks get more battery capacity, at least for a while. Good luck!

MBP temperature when on battery power

Is it normal that my MBP runs so hot when on battery power that I cannot even use it on my lap? It seems like most of the heat is coming from the area below the top 3 rows of keys (if that makes sense) and not the battery itself.

Yes, the case is a heat-sink; Apple call them "notebooks" not "laptops" and warn against having them against your skin.
"Do not leave the bottom of your MacBook Pro in contact with your lap or any surface of your body for extended periods. Prolonged contact with your body could cause discomfort and potentially a burn"
MacBookPro_UsersGuide page 107
Actually, you don't want heat near the battery itself as that's not good for li-ion, that should feel relatively cool?

MBP 15" video card problems while on battery power

I have a MBP 15" that I got about 3 weeks ago. I noticed that when I put it on battery power the video display becomes broken up laterally. I can drag the window or app window out of view then back into view and its ok. But if I start scrolling again, the text, image, video or whatever is on screen becomes distorted.
could this be a bad video card? should I try to get it replaced?
Any insights?
thanks!

I'm having the same issue--it looks like a tearing or smearing of lines of text, mainly in Safari, though I have seen it in Mail. I haven't noticed it related to running on AC or battery, but it may be...I had an older MacBook Pro (core duo) running 10.5.2 that was fine and recently upgraded to a 2.4 Core 2 Duo and this problem has popped up.
This issue looks suspiciously like a problem I was having on a Mac Pro with the ATI1900 card--it was brushed off for ages as a "heat problem" or the like with the card, and then miraculously after months of waiting a firmware update came out that completely cleared up the problem...

MBP Retina "wake for wifi network access" while on battery power?

I have USB printer connected to Airport Express, and i can print from iPhone using "Printopia" while MBP on, but cannot print when the lid is close (sleep mode) & unplugged, so is there any way to activated "wake for wifi network access" while on battery power? Thanx...

Hi,
I am coming from the MacBook faction, but there were similar posts in there, regarding at least your picture#2, the vertical colored lines.
The consensus was (and I cannot write from own experience here, just relaying the message) that this has something to do with system parameters. To rewrite these parameters, one has to set a different screen resolution than the current one and save the settings and then go back to the old resolution again and save the settings as well. We were told, this would prevent the colored vertical line issue, at least for the MacBook.
Worth a try, it is easy enough to do.
Regards,
Woelund
