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.

IBook g4 only sleeps on battery power. Other than putting never sleep in the energy saver what else can be done?

iBook g4 only sleeps on battery power. Other than putting never sleep in the energy saver what else can be done?

Do you mean it will only go to sleep when running from the battery? Or do you mean it won't do anything except sleep when running from the battery?
You could try resetting the PMU. The PMU has control over the Sleep function, so resetting it may help.

T61p freezes randomly when on Battery Power

I recently got my new T61p and i'm absolutely loving it. However, randomly (and only when the laptop is not plugged in to AC power) the system will hang on certain tasks, usually web surfing since thats what I'm usually doing, and I'll have to do a hard reboot. Consequently, internet explorer and mozilla firefox tend to freeze sometimes when I'm on battery power. When I'm plugged into AC power everything runs perfectly.
According to this website http://www.utheguru.com/lenovo-ibm-t41-random-crash, this guy had similar problems with his t41. I have all the latest versions of power management and updated all drivers and patched vista. Any ideas on what to do? I don't want to uninstall power management b/c its so useful
edit: I use the 'Energy Star' profile for my power setting
another edit: Apparently it is to do with the Intel turbo memory. i'll try the solutions in this post and give u my progress: http://forum.thinkpads.com/viewtopic.php?t=51908

I got my T61p last Friday. I'm having the same issues after applying all patches and driver updates. I can run fine on AC power, but as soon as I unplug the machine, the screen goes blank and I have to do a hard reboot. I have not been using Turbo Memory. For a few days it worked just fine, but then the problem started up again yesterday. I think it has something to do with the GPU.

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.

T42 Freezes Up when on Battery Power

I have a five year old T42 running on XP. When I'm on AC power there is no problem but when I switch to battery power the computer will boot but freezes up within a few minutes. When I re-boot the disc check comes on but freezes up before it completes. I have changed batteries but that does not help. Any suggestions?

I got my T61p last Friday. I'm having the same issues after applying all patches and driver updates. I can run fine on AC power, but as soon as I unplug the machine, the screen goes blank and I have to do a hard reboot. I have not been using Turbo Memory.

Q505-832 Freezes up when on battery power

My Q505-832 is running W7 home premium. When running on battery power the computer completely locks up. This happens after different amounts of time. It may lock up right after a boot. It may run for 15 minutes. All drivers are up to date with those on Toshiba's site. The computer runs fine while plugged in. The problem happens when the battery is fully charged. To be clear the computer doesn't die. The screen and everything stays on but I can't do anything. No mouse, no Alt-Tab, no Ctrl-Alt-Delete. All I can do is hold the power button down until it shuts off.

Hi padi,
Thats really strange issue...
Some more details about your notebook would be interesting. Are you running preinstalled Windows version or have you installed another OS?
Theoretically it could be a software/driver issue or hardware malfunction. At first I would reinstall Windows using Toshiba recovery disk.

New battery/power supply problems

i bought my ibook on ebay, put in some upgrades and am pretty happy with it. One thing keeps making me extrememly angry. Randomly, without warning, the power supply cuts out. When I look at the port, the light's still on. This wouldn't be so bad because usually the battery would kick in. However, mine came without a battery. So, everytime my power supply cuts, the computer shuts off. What's the problem?

Mike,Check your Energy Saver options (Apple Menu > System Preferences > Energy Saver > Options Tab > 'Schedule' make sure this isn't set to turn off your iBook.
I'd also try resetting the Power Management Unit. (Click this link and follow the instructions).
At least your clamshell's a good deal lighter! (Doesn't it tip back too easily without the weight under the front?).
The problem with running a machine like this is that the Clamshell has no internal battery (unlike every other Mac ever!) this means that you really do need the main battery for correct operation of the system. You'll be forever re-setting date/time etc so it may be worth inv a main battery - even if it's a really cheap one that only gives you 10 minutes run time - it will guard against this type of problem.

Battery power alone can be used to track Android phones

Now our phones can be tracked without GPS can you believe it ?
BBC News - Battery power alone can be used to track Android phones

     I'm trying to do the same thing, and have had limited success with an app called Control Plane. Please understand that I am pretty computer illiterate so this may not be the best way, or even a good way to accomplish this.   http://www.controlplaneapp.com/
     It allows you to automatically toggle bluetooth(and many other aspects) on or off under certain contexts. I tried setting it up to detect the display connection but sometimes it would detect the display, and sometimes it wouldn't. So I set it up to detect the specific power adapter for the display. So when I plug the monitor power adapter in it switches to the context i labeled "monitor" and I set an action to toggle bluetooth on under this context, when I unplug the power adapter it switches to a context I've named "battery" and turns the bluetooth off.
     Automatically turning the bluetooth on is specific to only connecting the monitor power adapter, when other power adapters are connected it does not turn bluetooth on. But it is limited in the fact that if I have bluetooth on in instances other than the monitor connection, and then disconnect any power adapter, it will automatically turn the bluetooth off.
     Also if my computer is in clamshell mode, and therefore asleep, when I plug the monitor+power adapter in it doesn't automatically turn on bluetooth, and I cannot use my bluetooth keyboard or trackpad to wake the computer. This forces me to open the computer momentarily to allow it to wake up and control panel to turn on bluetooth for me.
     Since my main issue was that I didn't want bluetooth on constantly to save battery life, this works for me, but it is not ideal. Ideally connecting the monitor to the computer in clamshell mode would wake it from sleep, but as of now I can't figure out how to make it do that. If you have any suggestions on how to make this process more efficient please let me know. Hope this helped.

DV5020US On Battery Power

I have a four year old laptop, model DV5020. I've used it heavily, and got a new battery 2 years ago right before the warrenty expired. Anyways, there's always been one problem with the notebook which I have never found an answer.
I have cool'n'quiet turned on, and it works. When I'm on AC, my clock is at 1800MHz, when I'm on battery it switches between 800MHz and 1800MHz depending on the load. Great! I can get 2 hours of battery life.
But, when I'm on battery, sometimes the CPU utilization pegs at 100% and the speed stays at 800MHz. If I turn off cool'n'quiet, my CPU will still ocassionally peg 100%, but I'm at 1800MHz so its not so bad. This ONLY happens on battery power.
So my question is why? I though maybe a rogue process. But I run Windows XP and Linux on it. This happens on both, exactly as described above. So it's not a rogue process. I've looked to quantify what is using all of my CPU time during these weird periods where my CPU peg, and this is what I've found.
There is no process that is using 100% cpu, or even close. Instead, every process is showing increased CPU utilization. The normally 5%, will go to 40%. The 2 and 3% will go to 10-20%, then 0% grow to 5 or 10%. It's almost as if my system is slowing to a halt.
So with this realization, I believe it's completely a hardware issue. It happens whether or not cool'n'quiet is on, independent of whatever OS is running, and only on battery power. Does anyone have any idea?

Hi p,
Sounds like a battery going bad. You can try an SMC Reset: http://support.apple.com/kb/HT3964, but don't count on it working. Look in System Profiler > Hardware > Power and see what it says for battery conditon and number of cycles.

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.

T43p - Mouse pointer freezes after changing the battery to a new one

Hello,
I have bought a new battery for my IBM Thinkpad T43p. In the description of the new battery I have seen that this battery is compatible with T43 series. Battery details are: DC 10.8V 5200mAh/56Wh. Replace: 08K8214.
My problem is:
I have ordered a new battery for my Thinkpad T43p but when I turned off the notebook and replace the old battery with the new one the notebook became strange. I use Windows XP Prof on this computer and when the login screen appeared and during I was typing my user name and password the mouse pointer was freezed and I had to turn off the computer. It was happened within approx 1 minute after the Login screen appeared. The symptom was the same with or without plugged in AC charger. I have tried several times and the same behavior was happened. When I changed back the old battery the computer became normal again without any freezing. The fan was working properly in both cases. The symptom is the same if I change the battery during AC charging and using Windows.
I don't have an idea about the reason of it. Can you help me with ideas?
Thanks in advance,
Slider

Pull the battery out and run the machine on AC only. Does it freeze now?
If it doesn't, the "new" battery needs to be replaced.
Good luck.
Cheers,
George

2008 MacBook freezing only when battery is attached

My 2008 black MacBook freezes when the battery is attached. If it is removed and ran on only AC power that machine works just fine. I have two of the exact same MacBooks (black, 2008) and have tried swapping batteries. According to system profiler they both are just fine. It seems to happen even if the machine isnt moved. The freezing is a hard freeze, that is, i cannot move my mouse or type and everything is just still. I have heard that some kind of ribbon wire could be the problem and people have said that putting a piece of paper on/around it can temporarily solve the problem. I am unsure of how to do this and am not even totally sure if this is whats wrong. Does anyone know of anywhere i can find good instructions for this? Will apple fix the problem? for free?
I have tried reseting the PRAM and SMC, both do not work. I have also erased the hard drive and reinstalled a fresh copy of snow leopard (i lost installation disc 2 of my original OS X cds, so apple told me to buy a new copy...over the phone that is). At any rate, the installation worked just fine and nothing has been installed or modified since. I really would like to fix this ASAP because I intend to give it to my girlfriend for our anniversary in a few days.
Please let me know if you have any input
thanks

First, try this:
1. Shut down your MB
2. Have ONLY the battery in it.
3. Power your MB up & immediately take it into Safe Mode (after the startup chime, hold down one of the Shift keys until the login screens shows up. Let go of Shift. Log in. Let it finish booting. At the Desktop, do a few ordinary things on your MB (not all programs will function in SafeMode though).
4. Report back here whether your MB freezes on battery-only power while it's in Safe Mode.
Second, download & install the iStat Menu utility.
After installing it, make notes of the MB's internal temperatures, particularly the 3 battery sensor temperatures when A) It's powered by only the adapter and then after a cooling down period, B) It's powered by only the battery. The Battery Temperature reading in iStat should show right around 85-90 degrees.
Here's a screenshot of my own iStat, with the mouse arrow pointing at my MB's current battery temperature:
Also, need some answers to these Q's:
1. What model is your MB?
Apple.com: "How to identify MacBook models"
EveryMac.com: "Lookup Mac Specs By Serial Number, Order, Model & EMC Number, Model ID"
2. What version of OSX are you running in your MB?
3. Did the frequency of the battery-only freezup problem develp slowly over time, freezing only every once in a while until now your MB freezes quite often, or did the problem just show up overnite -- yesterday, fine; today, freezing with only the battery in it?
4. Did you do anything major as far as changes to your MB are concerned, or did anything happen to it? (dropped, keyboard spill, etc)
This is an important one:
5. If you were to start your Macbook up in the morning on battery only after it being shut down all night, and the MB is being used normally, how long in minutes does it take, on average, for the first freezeup to occur?
6. When it is powered by battery only, and absolutely nothing has been done on it for quite a while after it's been turned on, & it's just sitting there with the screen open & the screensaver is running or the display is in sleep, does it freeze up?
7. Compare the temperatures of the bottom of your MB between 15-20 minutes of Power Adapter only use, and 15-20 minutes of Battery only use, with a cooling down period in between the two tests. Is there a huge difference in the two temperatures, or not much difference?
We'll get it.......
But I & other helpers who read your post just need more info from you before anyone can go any further with this.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.

This is from Apple.
2 to 3 hours seems very low.
what is teh standard or advertised spec for a 15 inch Macbook Pro with this battery.
I would like to know so that i can return it if this is not normal.
Its expensive so comments would be appreciated.

I say it depends on your model? average usage is about 3-4 hours depending on what you use and how you use it. Adobe Flash player eats a lot of battery power so if you are on a web page and has flash player, likely that it's eating up battery because of it's power thirsty.
Also check your systems activity monitor. It could be possible that one of your program/apps did not close right and may be still running. So check for that and end the process if necessary.
If you have a backlight keyboard, in a broad daylight, it's not necessary to have it on.
I also suggest that you use it plugged in most of the time, and it's not going to hurt or damage the battery if you have it plugged in all the time. Only use on battery if you are going to places that has no access to the outlet. If you are at home, then keep it plugged in. Just keep in mind to fully drain the battery until it your MBP turns off on it's own. This is the calibration process so that you have the most accurate battery readings.
The standard for 2011 MBP is 7 hours on battery. Before that model is 10 hours, but i don't believe that previous models will last 10 hours. Last week I calibrated my battery readings from fully charged and it took 9 hours to completely drain out the battery (I have a 2011 model),
If you think it's not normal and that your battery doesn't meet your expectation then set up an appointment with the genius bar and have them test the battery. They will determine whether it is faulty or not.

Freezes on startup screen with new Battery

laptop works fine with old Battery just battery will no longer hold a charge installed a new Battery freezes on startup screen ran battery test ok got a 2nd new Battery using the numbers off the old one same thing followed hp noteboook pcs testing and calibrating the battery everytime the first part says battery ok the 2nd part says na. reinstall old battery laptop works fine

Thank you for visiting the HP Support Forums and Welcome. I have read about your Compaq-Presario and having an issue with the New battery. Here is a link to test and calibrate the battery.
Plug the power adapter directly into a functioning wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue.
If that does not help try the Microsoft ACPI-Compliant Control Method Battery is basically the driver that communicates between the computer and the battery. There is a chance that it is corrupted. It is reading the battery level wrong, so the computer thinks the battery level is higher then what is actually is, so when it runs out of juice it shuts down.
Step 1. Go to Device Manager
Step 2. Select Batteries
Step 3. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there
Step 4. Click Uninstall
Step 5. At the prompt put a check in the box to remove the current driver
Step 6. Shutdown the computer
Step 7: Remove the battery for minute and then put it back in
When the computer comes back up it should automatically find the driver.
Step 8. Go to Device Manager
Step 9. Select Batteries
Step 10. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there
Step 11. Click "Search automatically for updated driver software"
Do the same thing with Microsoft ACPI-Compliant Embedded Controller.
Hope this helps.
Thanks.
