PowerPC :: Lithium Battery In Ti Powerbook
Sep 15, 2006
I've been having with my 500MHz Ti Powerbook. It has been acting very temperamental during startup where it will not startup at all, the fan will come on but no screen, or it will chime twice (and it's a weird sounding chime) and not startup, or it will freeze after logging in or during the log in stage. I got it to boot up once, but since then... it's dead. It will not startup. A friend tells me it's the internal lithium (PRAM?) battery that needs to be replaced

Kind of a silly question but I was looking to buy a battery replacement for my macbook pro. See signiture. My macbook pro uses a lithium ion battery. I noticed that eBay sells the same battery but in a lithium polymer type. Would it work in my computer? What is the difference really anyway? Should I assume that the lithium ion gets 300 cycles and the lithium polymer gets 1000 cycles. I know thats with the new uMBP but what about the aluminum MBP?

I am leaving for a week long trip and many parts of it will not be able to run the computer off of the powercord, which is a problem because I get about 40mins of wordprocessing use out of it when I run the battery alone. Can someone explain what the significance of these levels are for my Powerbook G4 15'' (Alm) 1.25GHz, namely the cycle count and full charge/remaining capacity?

So I just picked up a powerbook g4 12" 1.5 for a notetaking/work/travel computer, and it's all good, but I had a quick question about the superdrive- aside from needing to reinstall leopard, I don't think I ever need it. this may be a stupid question, but if I take out the superdrive, will that give me more battery life and make the computer lighter?

My Powerbook G4 is only 2 1/2 years old, and yet my battery only lasts for a short time. I've read various consumer reports that laptop batteries these days (regardless of computer brand) only last 2-3 years, so this disappointingly seems to be the norm.A replacement battery from Apple costs quite a bit, so I can't help but think that if I replace the battery cells inside the battery casing myself I could save a bundle. This and this site shows how, but so far I haven't found anything specific concerning the Powerbook G4 battery. Does anyone here have more info on the subject?
By the way, what's the best way to "reset" the battery? My Mac seems to be uncertain of how much power the battery actually has (it might show 45 minutes left, then suddenly turn off) -or maybe this is just a sign of a worn out battery.

Some days ago i finally added a Powerbook g4 to my Mac collection and since then ive been trying to fix this computer without any results. The Powerbook had the battery dead at first and i had to replace it with a new one i had. Now the problem/weird thing is that the computer detects the battery but it doesnt charge. It has about 18% of the charge and when i try to boot up all i hear is like a fan sound and nothing more, no boot up sound and no image on the screen.
If i boot up using the power cable thats when i see the 18% of the battery icon, but as soon as i take out the power cord, the image goes black although the computer still makes sounds as if it was on. Does it have any solution? PS: ive tried to reset the PMU,changed the pRam for a new one, reset the Nvram.

I have and old, but powerful, powerbook g4 667 (gigabit ethernet) with leopard 10.5.2 and runs well, but the battery is crazy:
Capacidad de plena carga (mAh):26564 (full capacity charge)
It's possible to fix? I read that reseting power management, but doesn't seems to work. It's is possible that leopard is causing this? the battery problems begin when install leopard.

My Powerbook G4 only turns on if the battery charger is plugged in, and if I unplug it, the computer shuts off. On the menu bar, it says charging. I know the battery has to be full. This just started happening last night. Also, I just had the hard drive replaced and I've only had it back for a couple weeks.

My Powerbook will not power on. I have followed some instructions on disconnecting the PRAM battery and that did not work, any ideas? I just stopped coming on without any explination.

I have a Powerbook G4 1.67GB with 2GB ram.
I am constantly having problems with the laptop shutting down when it is just on battery. It doesn't do this if I am plugged into power.
It does this on a random basis whatever program I am running but generally at 80%. I currently have Leopard as the operating system.

I have a 1.33ghz 12inch Powerbook with 768mb of RAM, my battery lasts for about 20 minutes, I am on my 4th ac adapter (and it is already broken again, I so get why they made them magnetic in future laptops). I am running Tiger... everything works just fine except the embarrassing battery life and unpredictable charging (b/c of the semi-broken power adapter).

I have a 1.67 GHz Powerbook G4. This morning it was fine. When I got home from work, it decided that it suddenly no longer wants to stay on when not plugged in. The battery is showing a full charge. The light on the plug is green. But the second I unplug the cord from the laptop, the entire thing shuts down.

My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

My 12 inch powerbook does not start up. Instead it loads to Darwin. I have an install disk from a 15 inch powerbook G4 and I would like to know if using this would work on my 12 inch powerbook G4?

I just purchased a 2005 Powerbook G4 12" and ordered a new battery. Unfortunately, when I stick a coin into the battery release latch on the underside of the computer, it just keeps turning around without ever releasing the battery. Therefore I'm guessing it's broken, and the battery is stuck in there. What do I do now? Can I take it to a Genius bar?

I am hoping someone can give me some advice. I have a G4 Powerbook that I've had since 2003 (yes I know in computing terms that's ancient-but we were getting along fine...!) 15 inch, 1.25GHz/512/80/SD. Replacement battery about 18mths ago, no other problems.
On Wednesday evening it completely froze and I had to press and hold the power button to turn it off. And that was it, nothing more, no whirring, no noise-It just won't do anything. Have tried resetting the PMU-several times, ac cable and battery are fine.

I have a Powerbook G4 1.5 w/ 1GB of RAM and the stock 80GB HD. I've run this puppy pretty hard for a couple of years now, and it's lately started to lag a bit - perfectly natural. I was considering buying a new notebook but I've decided to wait until after Leopard comes. So my question is:
1) How do I determine the max RAM I can put in this machine?
2) Are there are specific specs I need to be concerned with when swapping out the Hard Drive? Any type, size limitations, speed limitations, etc.
I'd love a little input as to how I find out this info. I think instead of taking the notebook plunge now, I'm going to put a nice new hard drive in this one and possibly bump up the RAM a little more if it will take it.

So is the is Powerbook G4 802.11g or b? it is the 1.25GHz model. Also, one thing I don't understand regarding the airport extreme or any airport for that matter: isn't the maximum speed going to be completely determined by how much the cable provider, Comcast, pumps out?
If this is the case, how do I determine what my transfers and speeds are looking like specifically for Comcast? And, how would an airport extreme improve upon this or any other performance aspect in this regard?

Powerbook G4 (Ti-book) 667 mhz, 512 mb RAM. I finally after YEARS upgraded my OS (10.4.10), yay me! Just bought Adobe CS3 (for the new IMAC we have yet to buy), but I would like to install it on my Powerbook. SO, it it time to bump up to 1GB RAM. I was told it was tricky, and I should take it in to the apple store to install, but then I took a look under the keyboard, and it looks pretty simple. i have installed new RAM on a G5 tower, and this looks way easier. So, I am planning on buying the RAM either online or at FRY's, then installing it. BUT, I know I have to be careful of what type of RAM to buy. I found what I think will be good at [URL] but I will have to buy 2 (512's) as mine currently has 2 (256). I guess I just want to make sure I am not going about this the wrong way before I drop about $200 for RAM upgrade...

I just bought a used 12" powerbook G4 1.5ghz and I want to add some ram to max it at 1.25Gb. Did anyone try to use ddr400 instead of ddr333 on powerbooks? In theory it will run at 333 like in any pc, but is this flawless in powerbooks? Because ddr333 is expensive nowadays.

I know the powerbook is rather archaic now, but I'm trying to get a new Macbook and don't want to throw my old powerbook away. So.. I have a friend who wants to buy my old G4 Powerbook with 60GB capacity, 512 MB memory, 1.33 GHz cpu speed. It's extremely worn in, meaning, it won't last more than 20 minutes off the power cord, but someone could always replace that. So what would be a fair price to charge someone to take it off my hands?

I bought a powerbook G4. The ram is 512 mb but i want to upgrade that. Is it possible to place two 1gb cards in each slot. That i have a total of 2gb ram? Me was told that the max of the powerbook G4 is 1 gb. Is that true? And when it is true, is it smart to buy a total of 1gb for the powerbook g4? Or doesn't make that any difference?

I believe the hdd is dead so I need to find a replacement but I've no idea which cause there are 93487534231 kinds. Only thing I can really find via googling is that it has to be a 2.5" ATA but there are several different kinds of ATA hdds... so confusing. I was thinking this? [URL]

Just replaced the logicboard on a 01' Powerbook G4 Titanium Onyx and I'm getting the no video/beeping sound after the chimes upon power up.
3 beeps
3 lights (1 long + 3 quick flashes)
I don't THINK it's the RAM though, I thought these cards were good before the computer fried. I've swapped the two 256MB cards with each other, also plugged just one RAM card in both slots one at a time--still no turn on and I get the 3 beeps. Unfortunately I don't have any extra 144-pin 133 Mhz SDRAM chips laying around or i'd just test them. It seems unlikely that both RAM cards would be broken, in addition to the logicboard frying, unless the two events happened simultaneously. Previous install had the 667 Mhz upgraded processor and when I took the logic board out it was fried on the bottom with lots of corrosion/leakage on a good 5% of the surface area. Anyways, I replaced it with a 550 Mhz board. Could the beeping be from installing the different processor or is it more likely that I simultaneously fried both RAM chips plus the motherboard?

Do you guys think it would be worth it to spend the $50 to upgrade from 1.5GB ram to 2 GB ram in this machine with Tiger on it?

I am kind of new to the MAC world... I once had the really old ibook with the handle a long time ago..and I never got a new Mac due to some problems I faced!
But now, I want to go back to MAC because many things were developed and I missed using a Mac! So, now I am confused between the Powerbook12 inch or the White Macbook 2Ghz ? I really love the size of the Macbook but I am worried about the intel processor...?

This is ridiculous. After I went out and got a new screwdriver to install my 1GB stick of RAM, which I got off of Newegg, it is now not recognized by my computer. So now I'm running with 256MBs of RAM. Beautiful, thank you Apple.
[URL]
This is what I ordered...Crucial Technology 1GB 200-Pin DDR SO-DIMM DDR 333 (PC 2700) Notebook Memory - OEM
I thoroughly made sure this was the right RAM, and even people with my same type of computer have said it works on their posting thing.. 1.5 GHz PowerBook G4 15". Anyone know how I can get this to work?

My PowerBook 12" 1.5G has 100% CPU usage when playing back the new TV program from iTunes store. And sometimes it even choke.
While I have no virus scanning software, some programs running such as Opera, iTunes, Entourage and have about 20% CPU usage when idle.
Why is it so slow on a PowerBook while you can actually play that video on an iPod? Is it the iPod too powerful or it is just because apple did not optimize enough for older Macs (pushing people to new hardware)?
I have just ordered a new iMac but I am not happy about my PowerBook which is just one year old.
