Power Book battery

Did anyone experience the heat generated by the Mac book Pro when its being connected to the power source? ...Is that normal? , further the battery does not get charged properly I think as the back up is hardly 45 Min..Please help me..

Hi Sunny65,
If you're running the machine with extensive CPU/GPU load while the unit is charging there's going to be some excessive heat. I've noticed that if I try to charge my MacBook Pro while I'm playing a game it gets hotter than normal and the power brick gets very hot (also more than usual). I've come to expect this as normal as the combination of energy depletion and recharge is probably causing the warmer than usual sensation.
Are you noticing the unit running hotter than normal even when idle and just connected off power? Is the battery charging during this time?
I've also seen situations where an older battery that's depleted will cause the unit to run much hotter than normal when it's connected to power. The battery cells are not absorbing the energy from the charge and as a result is transferred into heat for dissipation purposes.
What's your battery health information? Apple Logo > About This Mac > More Info > Click Power on the left hand column
Copy and paste the battery information.

My 5 year old Mac book won't turn on. It seems to be holding a charge. In the past 3 months I've replaced the power source, battery, & had a full diagnostic run on it.

Tanks dominic23, do you think that the dead battery can affect the macbook performance? I do alot of video work, and since the battery died i cannot do a smooth preview of my videos in premiere cs6, seems like a memory problem but it worked fine before the battery issue.

Power Book 100

Here's the question.
I have an old powerbook 100 without a power supply. I found a universal power supply, you know the type selectable voltage and reversible polarity.
What I don't know is what the polarity of the connector socket on the back of the power book is.
Does anyone know if it is Centre Pin + or Centre Pin -
There is also a two position switch to the right of the DC socket and I don't understand the symbols I can't make out if it is a selector switch between battery and mains or a polarity reversal switch ?
Can any one help
I would like to try and see if it boots but don't want to risk blowing the computer or my digital PSU

More notes on the PB 100 here:
http://docs.info.apple.com/article.html?artnum=16168
points worth noting ( direct quotes from that page:
Note: "This adapter was replaced by model M4662."
"The fourth AC adapter, 17 W, came with PowerBook 150 computers, and works with PowerBook 100 or 150 computers.
Warning: Using an AC adapter that produces more than 19 W with a PowerBook 100 or 150 computer will damage the computer's logic board."
The irony is that the M5140 for the PB 100 was repalced by the same power supply that replaced the 24W for the 180c but the warning seemingly contradicts the replacement note.
This also gives some good background info. Still looking for the 100 power supply.
This link:

leads to an outdated PB100 panel link. Time to hit google.

Power Book vs. Mac Book Pro for Computer Science Student

I am a Computer Science Masters student that is looking into switching completely off of Windows machines in my home in the next 2 to 4 years. I’ve never used Macs before, but I’m tired of feeling like my hands are tied with Windows and I’ve been impressed with the G4 Power Books some of my peers have. I’ve actually been so impressed that I decided I want to start my switch from Windows to Mac with the purchase of a new Mac powered laptop for school.
I plan on using this laptop for the following tasks: writing papers, writing/compiling/debugging programs including an independent study project on OpenGL Computer Graphics, photo editing and some webpage design. Also some game playing and movie watching when I’m traveling.
So my question is this, do you think a 12" Power Book or a Mac Book Pro would serve me better? I am on a budget so if I get the MBP I wouldn’t have a lot of money left over after buying it for additional software, but if I purchase a PB I’m afraid it won’t be "up to snuff" or that the Power PC chip will stop being supported by future software. Are these fears unfounded? I do know there is a student discount and I’ve already taken that into account in regards to pricing.
Thank you in advance for any advice you can provide me.

I'm not a compsci student, but I think I can give you some insight on what to expect...
The G4 will handle a lot of what you throw at it, depending on how much RAM and how many things. I'm still running the stock 512MB and have found little-to-no need to upgrade at this time. I even went so far as to try a 1GB PC2700 SODIMM from my HP ZV6000 and it didn't change anything, so I'm good for now. Over the years, I've been impressed w/ the performance and efficiency with the G4 design and architecture, so I doubt there will be anything that it can't do based on what you're describing.
Gaming may be another story, although with the latest rev. of the 12" PB, I am impressed and mildly surprised at the performance w/ gaming. I play Call of Duty and Doom 3 on occasion and both run great. Just remember to put your processor performance on "Highest" as to turn off the processor throttling (much like Cool 'n' Quiet on AMD architecture). I played Doom 3 last night w/ medium quality @ 1024x768 and it ran quite well... Call of Duty will fly even on battery (ie. reduced processor speed) or AC... I've yet to try Call of Duty 2 but I hear it's going to be a monster w/ system requirements.
Writing Papers -- You can do this with anything...but if you're referring to the comfortable aspect, I think you'll love the keyboard personally. Typing on my big HP and on my 12" PB, it's night/day. The HP has a good keyboard, but it's not something I can 'fly' on...and by fly I mean 80-90WPM w/ little to no mistakes. I notice I make fewer mistakes on the PB keyboard because the keys seem to be 'grouped' together better and it's got a nice feel when you're slamming the keys down while you're in thought on a particular subject.
I also use Office X (or 10)...have had no need to upgrade since it works very well for what I do. I've never used Appleworks...
Future Software? -- Two words -- Universal Binaries...they will be around for many moons to come, and then some. Apple supported 68k for almost 11yrs (if I'm not mistaken) and software developers have already committed to Universal Binaries (aka. UB, or Fat Binaries) because of the sheer install base of PowerPC. The Intel transition will probably be in the 'teething' stage for another 2yrs before it's the standard Apple base across the board, and by then it will still only be a percentage of the PPC install base. Rest assured--your PPC Mac will be working long after you even upgrade (4-6yrs down the line).
The only thing I recommend is AppleCare, and not because I get anything from Apple over it. I've used it on my Rev. B (1.0Ghz) 12" PB and it paid for itself in the last year I had it. It covers everything that isn't accidental, so if you have issues w/ the LCD or Logic Board (aka. MLB), it'll pay for everything and shipping (both ways). It's also worldwide, so if you're on a trip to the UK and have problems w/ it, you can stop by any one of a handful of Apple Stores (Regent Street is awesome, I'm told) and they can fix it for you. There's also hundreds (if not thousands) of Apple Authorized Service Providers worldwide, and from what I'm told, they prefer Apple over many manufacturers because they are 'no hassle' when it comes to warranty claims. In other words, AppleCare may be the only investment that you may never use, but if you do, it'll pay for itself.
Computer Graphics, well, I don't do graphics but I can say that almost everything Adobe makes runs and runs well on Mac hardware.. I think you'll love the Quartz engine too...it's really quick compared to Direct X (I notice this in gaming, but what do I know...).
Good luck to you in whatever you decide...

Power book funeral??????

For the last few weeks my Power Book has been crashing. Lately it froze and crashed doing everything but internet and email so I ran the Tech Tool and ran the Apple diagnostic disk with the results below.
Tech Tool-Volume Structure Failed (Error:-92)-Repair
Apple disk Utility
Invalid B tree node size
Invalis B tree node size
The volume needs to be repaired
Volume check failed
Can anyone please interpret these dismal sounding warning for me please?

The flashing ? folder merely means it has no system folder it can see. A bad directory can cause this problem*:
http://www.macmaps.com/directoryfaq.html
The bad directory may also be the result of an automatic shutdown not happening properly like you described, so it is hard to know which came first, the chicken or the egg.
It is also hard to know if the result of the bad directory has also rendered the power management preferences damaged, or if the power manager itself or battery is damaged.

How do I find a previously passcode to link a wireless keyboard (Model A101urs6) to a Mac Power Book G4 running 10.5.8. The keyboard was linked at one point in the past, but then not used. When I am trying to hook it up now, it requires the passcode.

AT commands for 17" Power Book G4 internal modem.

1. How does one issue AT commants to the internal modem in a 17" Power Mac G4?
2. Are they the "standard" AT commands promulgated by Ma Bell? If not could you point me to a list of AT commands used by the Power Book G4 internal modem?
3. Thanks!

You can modify the modem script you use to send additional AT commands to the modem. The Apple modem uses the basic Motorola command set. You can find the manual here.

I have a power book g4 can i upgrade my current os 10.4.11 to 10.6

I would like to up grade my power book g4 from its current os 10.4.11 to 10.6.8. Is this possible

PowerPC systems can only upgrade as high as Leopard (10.5). Leopard disks run as high as $200 online.
SL requires Intel processor.

Hi, I have a Power Book G4 Tiger 10.4.11 and my problem concerns iTunes 9.2.1(5). I have changed my Apple ID and password recently. Since that, I am told when I try to buy something in iTunes Store that my "session has expired". Where does this come from?

Power book G5 flashing ? mark with file icon !

My power book G5 is showing a flashing ? mark in the middle of a file icon, it doesn't want to respond to any disk's or function keys, please help.

I might add, here is an image of the machines known as the PowerMac G5:
A very similar Mac which is not a G5, is called a Mac Pro:
Note the extra drive bay on top for the Mac Pros.
iMacs came in both G5 and Intel models and are both white in appearance. To tell the difference between those two, you need to read the EMC model on the foot, and use Apple's article here:
http://support.apple.com/kb/HT1463?viewlocale=en_US
Powerbooks and iBooks are both clearly indicated what machine processor they are under the screen. If your 4 or 3 key is broke, feel free to use Roman numerals:
III is 3
IV is 4
It is very important you state which Mac model you have, so we can tell you what article can better identify your Mac so we can troubleshoot your problem further.

My external monitor works but I can't get my screen to work on my power book anymore

Can not get my screen on power book G4 to work but my external monitor works fine. Did I press something and turn it off?

The both screens always worked fine but now the power book doesn't show anything on the screen. I didn't drop it or even move it. Where is the brightness button? Could I have hit it by mistake?
Thanks so much for your help.
F2 is the up-brightness button, F1 is the down-brightness button, usually, on PowerBooks. If for some reason the F1 button got held down for a couple of seconds, the display would go completely dark.
That being said, if the backlight does not come up (easily determined by seeing if the Apple outline on the cover is lit up) then the most likely suspect would be the inverter board, or the connection to the inverter board. If this is a Titanium PG G4, the inverter board is easy and relatively inexpensive to replace. For the Aluminum models, I don't know if that is quite so true.

UPGARDING PROBLEMS!!! NO CD Drive on a Power Book Fire Wire

First Of All Hello Everyone:
Here's my problem, a friend of mine ask me for help with he's power book Fire-wire the machine has (768 MB on RAM and 15 GB on HD),To upgrade his OS 9.2 to OS X, but (Here's the real problem) it has no cd or dvd drive, (Actually no cd drive at all), so i can't upgrade it to OSX. I Have tried with an external Iomega CD Drive (Predator Model) but it tells me it can't startup with an external cd drive, or simply doesn't recognize the external device when tried to startup the computer with the "C" key held down.
(It recognize the external cd when it's already stated up in OS 9.2)

Ikaro,
You cannot successfully drag-copy OSX like the 'Classic' OS.
If you could beg/borrow a FW CD-RW, you can boot the OSX CD and install via the burner.
Boot to the FW CD-RW in this manner: Load the OSX CD in the burner, then start up or restart while pressing the 'option' key, then select the OSX CD in the Startup Manager window.
Since you have a 10GB FW HD, you could connect it to another Mac (the host) that has FireWire ports and install OSX on the FW HD. The host should be able to start up to the new install on the FW HD so it can restart to the FW HD and finish up the install. If the host computer cannot boot to the FW HD, just let it restart to the internal HD, copy over CCC (see below), then properly unmount the FW HD. I believe you still should be able to boot the Pismo to the FW HD although I cannot be positive.
Now just connect the FW HD to your Powerbook (FireWire) a.k.a. Pismo, boot to the HD, and use Carbon Copy Cloner to clone a bootable copy to the Pismo's internal HD.
You will first have to download Carbon Copy Cloner from VersionTracker and place it on the host's HD. After finishing installing OSX on the FW HD, drag-copy CCC onto the FW HD. When preparing to CCC to the Pismo's internal HD, make sure you select "make bootable" in CCC's preferences.
