No Battery powerup 15" 1.67GHz

Someone at work is having issues with their PowerBook, it will power up just fine while plugged in, but stopped recognizing the battery. First thing we did was swap in a new batery we had on hand. The notebook will recognize that there is a battery plugged in, but will not charge it and just keeps displaying "Calculating time until full" in teh status menu. The new battery works fine in other units and we have already one a PMU reset on the problem unit. Any sugegestions? Our best guesses are either the DC-In board or the motherboard itself.

Is the computer managing to give any information about the battery in system profiler? (apple -> about this mac -> more info button -> power (in the hardware section of the list))

How do you find out if your laptop is a 15" Titanium or Aluminum model?

As above please - Mine is dead, and prior to posting a question I need to verify which model I have so I can post in the correct section!
I have removed the battery on mine, the info on the battery states: "15-inch PowerBook G4 Rechargeable battery" and the info next to the Serial number on the inside of the battery compartment is: "1.67Ghz/512MB/80G/SuperDrive/BT/APX/Backlit KB".
Basically the laptop recently stopped working - just boots up to a blue screen, cannot start any programs etc. I think it may just be over loaded with memory, which brings me onto the question - I have an Imac with firewire connection, how do I go about booting using firewire and copying some stuff off my laptop to see if that will fix it?
Thanks!

1.67GHz G4 15-inch Battery

Just opened 2 brand new powerbooks and neither of them will charge. The reading is at 0% and the light is green.
tried resetting the power management unit. No change.
ANything else I could try/do?
Thanks in advance.

It's possible that the internal battery is dead. Often just leaving them plugged in for a long period helps get them started. First try for an hour then if that fails try for six, over night would be simplest.

PowerBook G4 15" 1.67gHz (Model A1138) won't turn on (it's not battery)

I just replaced the hard drive following instructions on ifixit.com (really great site by the way for anyone wanting step by step repairs). I did it all right, but at the moment of truth... Nothing. Power's plugged in. Green light's on. It's taking a charge. But computer won't turn on. Reset PMU already. Nothing. Wondering if I fried the board with static even though I didn't feel any ever and was cautious about touch metal before anything else (plus I wore a static bracelet). I did Vacuum the inside with a brush attachment very carefully so the vac never touched, but in hindsight maybe ******* move...
I will take it to a mac store but thought I could get a quick thought from someone first.
BY THE WAY: The drive is totally empty and I didn't put a OS DVD in the drive before I replaced. Figured I could turn it on and then hold C and stuff the disk in, but it won't go on to get there.

After power-on... Do you get a light when you press the caps lock?
I would also agree with "BGreg" check the Trackpad/Keyboard ribbon cable.
And make sure that the RAM is fully seated.
I doubt that ESD would cause the Mac to not boot, in this case as it sounds like you took all precautions. Everyone should practice good ESD safety as it is always a possibility. Now using a bristle brush with a vacuum, well that's a different story entirely and that can zap it in a heart beat.

How do you know if the battery is dead? Detailed history. Help needed!!

So here's the story.
Bought the PowerBook G4 1.67GHz used off a trusted friend. Worked fine for 3 months or whatever up till yesterday basically.
The charger was in, orange light, but the charger in the corner was going from "Charge" to "15%" and switching (and decreasing) every 3 seconds so it seemed it wasn't really charging it or picking up the signal.
Eventually the thing died, and I thought I'd leave it off and charge (even if it is slowly) so that it will eventually be back up. The screen lid push button was lit up/glowing, so it must've gone into auto sleep.
It wouldn't turn on after that, even around 4 hours later, so I tried pushing in the the charger in a different way just to check and realised if i pushed it one way it would go Green and stay, but if i pushed it another way it would go Orange and stay. Wierd. Was it fully charged or not? It wasn't I think.
Eventually somehow, It seems a bit of charge got to it and I managed to get the Sleep password screen up and entered it in, then quickly shut it down before it depleted whatever was left already.
After this, the charger still did the same Orange / Green thing.
I looked up the problem and found a lot of those PMU reset things, did all of them to no avail. I realised that apparently the actual laptop should be able to support itself and boot without a battery - so I tried that, took out the battery and tried booting a lot of times but nothing happened.
Could it be the logic board? I knew that one of the Memory slots in the PB was actually non functioning so I knew it could be something.. Also another known problem was that a piece of the stupid charger prong on the PB charger broke, inside the laptop, but it was like that for around 6 weeks and always charged still. If it was that I assume that the charger wouldn't pick up a light at all then.
The light is still green on the laptop charger ring, but the laptop does nothing at all I can't afford a new laptop lol. I will give my local Sydney city Apple centre a ring and see if they have alternate batteries / chargers I can try but since its around 2-3 years old, I don't think they'll be able to help.

Fixed!
Took it to the Apple Store. They tried getting the stuck piece out for 20 seconds but to no avail. They searched for a spare battery and found one with charge and it worked fine. Quoted $80AU for the DC In Board and $150AU for the labour to get it fitted and fixed.
Took it home, spent half an hour with two sewing pins and managed to hook it out.
Now going to buy a new charger tomorrow (3rd-Party or Apple brand if out of stock everywhere else) and will be able to take it interstate with me after New Years! Woot woot!
Genius Bar is a huge help. God bless Apple and their customer service team.

PowerBook G4 12" Damaged by Bad Battery?

I have a PowerBook G4 12" 1.5GHz with a bad battery that is about to be replaced by the Extension Program. Can the bad battery have damaged the computer while it was in use in the computer? In early 2005, I purchased a brand-new PowerBook G4 15" 1.67Ghz which turned out to have a bad battery, but because at that time the battery problem was either not yet known or not yet acknowledged by Apple, the battery was not only used in the 15", but when it was sent back from Apple after the first of three service attempts, the bad battery was not replaced and was sent back to me and I, not having been informed there was a battery problem of any kind, continued to use the computer until its hard drive then its logic board failed. Eventually, I found out about the exchange program by accident (and was officially informed by Apple one year later, in June 2006; ironically, the 15" had been replaced with one of the first MacBook Pros in March 2006). I include this history because I have always wondered if the bad battery damaged the 15"'s logic board. Now this 12", which I just bought, whose bad battery has been installed for years is having major issues: the screen freezes within the first 2 minutes of booting from disk, hard drive or network boot image (it has never booted to the desktop since I've owned it); it heats up under the hard drive/near the video chip; when TDM is attempted, the screen stays black altogether and the 12" never appears on the host's desktop. It will boot into Open Firmware but not in single user mode. There is some kind of white sticky substance present in small amounts around the pins thar lock the battery into the well. For the record, the 12" is otherwise in seeingly flawless condition with no dents or other signs of being dropped and inside it is clear no one has disassembled it or even removed the topcase. When the battery is removed and the AC power connected it still won't boot. Sorry this is so long.

The actual runtime of a battery depends on several factors, including what you are doing with your PowerBook. Information on stretching out your battery's runtime is available in this article. For a daily planner, try using iCal in the /Applications/ folder, or dTasks if iCal won't do what you want.

Is the 4.3 bright Verizon boot screen really a battery drainer?

The notion that Verizon's 4.3 startup logo screen puts a big drain on the S III battery, purportedly because it's so bright, is unsupported. Anyone easily can test this by writing down the current state of the battery charge percentage (be it 100% or 50%), power off, wait 30 seconds or so, power up allowing all homepage apps to fully display, open System Settings and scroll down to Battery, tap this settings option and read the battery charge percentage listed. If your simple test is the same as several tests that I've conducted, the post-powerup battery percentage will be exactly the same as the pre-powerdown battery percentage. The 4.3 logo screen is bright, but does not contribute to any battery drainage as confirmed by every test that I've conducted.

how big of a draw can it really be, it's only on for 10 sec, then continues to the home screen.

Constant Charge and Battery

Hi there! I'm a recently converted PC user and I know that with most PC laptops, it's a good idea to remove your battery if you keep your laptop connected to it's AC adapter all the time. Would this apply as well to the G4 Powerbook (15 inch, 1.67GHZ)?
Another question that could possibly tie in with the battery as well; my Powerbook will get very hot after a few hours of use. Is this normal for this model or should I have it looked at by the Apple Store? I'm not terribly concerned as far as an electrical hazard is concerned, I'm more worried about if it'll overheat and possibly fry my hardware. Again, I'm a recently converted PC user and I know these things can happen with a PC (knowing this from personal experience) but I really don't know if it applies with Macs.
Thank you!

Hi there! I'm a recently converted PC user and I know that with most PC laptops, it's a good idea to remove your battery if you keep your laptop connected to it's AC adapter all the time. Would this apply as well to the G4 Powerbook (15 inch, 1.67GHZ)?
In addition to Apple's guide to the use and maintenance of its Li-ion batteries, keep in mind that spontaneous oxidation (unavoidable) results in a gradual decrease of the battery's capacity. In addition to the issue of trickle charges eating away at the charge cycles, exposure to heat increases this rate of oxidation, which is why keeping your battery in your PowerBook isn't ideal for its longevity. When not in use for an extended period of time, it's best to store the battery in a cool place at 40-50% charge. Your battery is under the most stress at 0 and 100% of its charge capacity.
If you're a roadwarrior, I wouldn't bother with taking the battery out. However, if you're using your PowerBook primarily as a desktop replacement, I might consider it. For more information regarding batteries, their chemistry and their use, refer to BatteryUniversity.

Geekbench Air 2011 slow on battery?

I have sold my 2010 Macbook Air 11-in and just bought a custom 11-in 2011 Macbook Air (1.8Ghz, 128GB SSD, 4GB RAM). I tried running GeekBench 64-Bit on my machine and got similar results as my sister's late 2010 Macbook Pro 15-in (2.67GHz, 4GB RAM).
However my Geekbench score is only 1/3rd when on battery power whereas my sister's Macbook Pro score is unaffected while on battery.
Does this mean that there is only limited CPU power for the 2011 Macbook air while on battery?

Here are the XBench Test Results for:
* CPU
* Memory
* Disk
* Open GL
You can see that with the exception of the disk tests, everything else was 1/3rd slower on battery vs AC power.

TiPowerbook Battery problem...with a twist

Hi
I have seen the numerous posings about flagging batteries etc, but mine seems a little different. My parents recently bought a 15" Titanium PB 667mhz from a friend of mine, which needed a new battery. They purchased a new third party battery from ebay and all seemed fine. Recently however, the PB has taken to shutting down on its own accord. It will powerup and the battery is still showing sufficient charge. Sometimes it won't power up even thought the battery indicators are showing fully charged. They are running jaguar and it has a PCI slot network card.
Can anyone help me convince these new switchers that I haven't convinced them to buy a dud?!
Thanks in advance

Hi, the r. Have your parents performed the battery calibration routine described in this article? Have they reset the Power Manager in their Tibook? Have they read this article for general information on managing a Powerbook battery?
If neither of those steps leads to any improvement, the "new" battery is probably the dud. Return it to the Ebay vendor or its manufacturer under the warranty that I presume came with it, and get another. If a second battery behaves exactly the same way, then yes, the Powerbook is a dud.

Firewire and USB issue on PBG4 15" 1.67ghz - Help!!

On the firewire 400 port of my Powerbook G4 15" I run an M-audio Firewire 410 external audio interface. This has worked perfectly ever since I got my powerbook in December 2005.
On switching on my powerbook only days ago, I found that although my Powerbook recognises my Firewire 410 as being attached and powers it, it will not play any sound whatsoever.
I subsequently tried my Firewire 410 audio interface with my PC running XP, which again finds it but plays the audio with high digital distortion.
I believed this to be a problem with my audio interface and not my powerbook - but on one of the USB 2.0 ports, I have attached a 250GB Freecom Classic External HDD. Again, since i got my powerbook this has worked fine, but now my powerbook will only recognise it as a 'Cypress AT2LP RC42' device that cannot be installed.
The Hard drive also will not work on my PC and I have found from other forums that 'Cypress AT2LP RC42' means that your hard drive enclosure is not getting enough power.
Both of these devices stopped working within the same week, and are now useless. The only common thing between them is they were both connected to my powerbook G4 when they stopped working.
I reset my power management system by taking out the battery and adapter and holding the power button, i've verified my permissions and powerbook HD, and still nothing. I have no other choice but to imagine that my powerbook has damaged these devices, which are both powered through their respective ports.
I recently upgraded to 10.4.6 through the system update utility, but quite a few weeks ago now.
Can anyone shed light on this, or give me any indication how to solve this?
Powerbook G4 15" 1.67Ghz Mac OS X (10.4.6)

This seams to be related to Firewire port only, I just switched to using usb extention cord on the same drive and its omovign information happly on both USB ports....
So question is how does one check health of the Firewire port and associated driveres, which logs to monitor and what information is prudent?

Strange major problem with 975X PowerUp Intel MOBO

I’m suddenly having a strange major problem with a MSI 975X Platinum PowerUP Edition V2.1 MS-7246 Intel socket 775 motherboard. Previously, it had given me no problems at all.
It went like this:
Powered on system in the morning, booting from a cold start.
Hit DEL key to get into the BIOS.
Missed the window and the system booted into Windows normally.
Re-started the system from within Windows.
Hit DEL key to get into the BIOS and was successful the second time.
Hit the ENTER key on the first item “Standard CMOS Features”.
The DATE, TIME and other information was displayed on the next screen, but at this point, the BIOS screen became completely unresponsive to any keyboard input.
The only thing I could do at that point was to power off.
Subsequent power on boot-ups resulted in the system always freezing at the BIOS splash screen after the video card sign-on.
I have switched power supplies, hard drives, keyboards and video cards. I have disconnected everything except the video card, keyboard and one RAM module. I have switched the four RAM modules around and then reduced the RAM to one 256MB module in the proper slot. I even changed the battery on the MOBO, in case it had shorted out and removed and re-seated the BIOS chip. It still halts at the BIOS splash screen.
The BIOS chip can’t be completely dead, because I powered off and pushed the BIOS reset button on the MOBO to reset the BIOS to the factory defaults. When I re-booted, I could tell that it had actually reset to the factory defaults because I had previously set the BIOS to reboot the system on resumption of power and the factory default was to remain off until the power button was pushed, which was now the default.
I’m stumped! All I can think of is to get a new pre-programmed BIOS chip and see if that makes any difference, but I’m not sure this system is even worth the expense with no guarantee of success. Any suggestions on how I might get past the BIOS splash screen or do I for sure have a corrupt BIOS chip?

System specs as per the posting guidelines -
Board: MSI 975X Platinum PowerUP Edition V2.1 MS-7246 Intel socket 775
Bios: Version (can’t recall & can’t check since it won’t go past the BIOS splash screen)
VGA: ASUS EN7600GS nVidia GeForce 7600GS PCI-e 256MB DDR2 (also tried new XFX nVidia
Geforce 210 PCI-e 2.0 512MB DDR3)
PSU: Chiefmax 680W ATX (also tried new OCZ 700W ATX)
CPU: Intel 2.8GHz LGA-775 Core2 Duo Dual-Core Processor
MEM: 4 x Samsung 512MB 1Rx8 PC2-5300U (2GB total)
HDD: Seagate Barracuda 250GB SATA2 (also tried Seagate Barracuda 500GB SATA2)
COOLER: Intel OEM LGA 775 fan/heatsink C25897-001
OC: No
OS: Vista Home Premium 32-bit
I have been through the BIOS reset procedure several times and pretty much as outlined. As I said before, I could tell that it had taken a reset to the factory defaults, because the power on option had changed.

Random Battery capacity!

A few days ago, I notices that my battery had weird reactions. The charge indicators fluctuates, goes into the red, back well into the black, ...
Yesterday, I checked wit coconut battery. It gave me a capacity of 1740 mAh (39%)!! Five minutes later, it showed a capacity of 4407 mAh! When I recharged the battery this morning, it stopped at the "full" capacity 2149 mAh and is now back to 4400 mAh.
My battery has 16 cycles (has been exchanged recently with the exchange program). What is going on? Any help would be greatly appreciated!

Hallo there,
i have got the same problem with my battery.
i received a new battery -also as part of the battery exchange program in germany- in October 2006. Now, since two weeks or so, the battery-life is just 1 - 1,5 hour, depending on activity (1 hour, if running iTunes and streamripper simultaneously, for example). I checked the system profiler for battery-capacity and noticed the same weired thing: max. Capacity is 2400mAh, then it's 27xxmAh some hours after, then 35xxmAh, some minutes after that it is 29xxmAh, a day later again at 27xxmAh, and so on...
i calibrated the battery and did pmu-reset (2x). charging the battery is no problem, 20 cycles were done for now.
i called apple-support, but they told me, there is no more warranty for changed batteries and they can not send a new one to me. they gave me no other advice then buying one. did anyone solve this problem, or any suggestions on that? And what may be the defective part, battery or pmu?
My system is a powerbook (bought in juli 2005) g4 1.67GHz, 512MB RAM, osx 10.4.9
greetings from germany and looking forward to your help

Battery update Question

I couldn't find an answer to this in the installer info or on Apple's info site, but I installed the battery update for the powerbook 1.67ghz hi-res dual-layer back when it was released, and what I'm wondering is, do I need to do it again if I reinstall the OS? I'm thinking not, because it's upgrading the firmware in the battery itself as far as I know.
Anyone know for sure?

I still have the updater, and I know the OS doesn't install it for me. I'm just not sure if the updater needs to be run a second time. I'm doubtful I need to though, because the updater updates the firmware of the battery itself, and the battery remains unchanged after a reinstallation of the OS. I guess I'll try running the updater and it should(hopefully) tell me whether or not it needs to be done. I doubt a re-update would do harm anyway, it's not like I'm trying to install older firmware over new firmware.

Received Battery Replacement for New Hi-Res Powerbook

But it's the OLD 2-3 hour type with the old serial number format.
By the way, the guy who set up the return on the phone told me that all the new batteries are bad and they are going to have to replace them. So , this attempt to use new 5-hour batteries has failed. What the ****, Apple. This the second revision of the 15' with battery recalls.
I'm selling this and getting a 17"

Which serial numbers are new and which are old?
The apple store gave me a replacement battery off the retail shelf. It's serial# is 3K5301CFT7AA. Model A1078.
It has lasted about 2 hours from a full charge when new... which is very bad. Now that it's 2 days old, its holding a 1h 20 min charge.
If this is a 5 hour battery, then clearly they are all bad. If this is an old battery, then the powerbook itself is having problems.
