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?
View 2 RepliesI 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 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?
View 8 Replies View RelatedI'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
View 2 Replies View RelatedMy 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.

I am running Tiger... everything works just fine except the embarrassing battery life and unpredictable charging (b/c of the semi-broken power adapter).

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.
View 6 Replies View Relatedi just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.
I calibrated my MacBook Pro battery and then noticed that the battery life seemed slightly shorter after that. I calibrated it according to this: [URL]
Just wondering if I have done anything wrong...
One more question... What do they mean by "At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep." Does it mean that I have to use the computer until it just shuts down or should I shut it down once the "Low Battery" warning pops up?

I have a 13" 2.4 GHZ white macbook that I bought in march of 2008. About 4 months ago I all of the sudden started having problems with battery life. It was very abrupt. I used to be able to take my macbook and sit through 3 classes or more with no trouble in regards to batter life. Then suddenly the battery would drain within a few hours. It has remained that way since.
I've spent the last month or so looking around forums and other places to try and find someone with a similar problem and possible solutions. As a result I've discovered that my situation seams to be somewhat unique.
Using cocoanut battery I tested my battery's capacity and it remains at a solid 98%. How can my battery still be at 98% capacity and have such a short battery life? I also seam to be losing charge while my macbook is closed. How and why does that happen? If I leave my macbook closed for a day or two it can lose up to 25% charge just sitting there!
I've tried loads of things including turning off unnecessary things such as sharing and bluetooth and calibrating my battery, all with no avail.
What is going on?? My battery is too old to be eligable for a recal and I'm not paying $30 just to have a phone conversation with a "Genius". If anyone has any idea what's going on and any possible advice, I would greatly appreciate it.
My two year old macbook pro battery life is getting shorter after recharging. I only get about 40 minutes on a full charge when it used to be 3 hrs. Is it time to replace the battery?

View 1 Replies View RelatedI've had this MBP for just over 8 months now, I'd intially purchased one in november, but the audio out used to give a crackle sound so they replaced the laptop. Moving on to the point - in the last week or so, I've noticed the MBP suddenly seems to get very hot and the fans turn on and thus suddenly becomes very noisy. I was using it on the bed so could appreciate that I may have been blocking the vents, but I've had it on a stand the past couple of days and it still seems to do it for no particular reason. The charger usually always gets ridiculously hot, but the MBP used to stay relatively cool, now the MBP gets hot independently of whether its being charged or not. Moreover, my battery life has gone from what used to last 4 hours, to around 2.25.
Cocunut battery gave the following stats:
Current Battery capacity: 4483mAh
Load Cycles: 222

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.
View 10 Replies View RelatedMy MacBook pro's battery life has really gone down hill. I bought a battery in September '09 and rarely used it. Recently I put it in because my original battery supposidly does not hold a charge. Now it only gets a hour when last week it got 4! What happened? What is wrong with my computer?

View 6 Replies View RelatedI am interested in getting a refurbished Macbook Air. I was looking at the following two models:
Macbook Air Rev B., 1.86 GHz, 2GB RAM, 128 GB SSD for $1349 OR
Macbook Air Rev C., 2.13 GHz, 2GB RAM, 128 GB SSD for $1549
Other than the processor difference of 0.27 GHz, and based on reading the technical specs of each system, I don't see any difference between the two machines. The one piece of information that I couldn't find was the advertised battery life for the Rev. B unit. The Rev. C unit is supposedly rated for 5 hours of wireless productivity. Is the same battery used in the Rev B also or is the battery of lower WHr?
My needs are pretty simple - I would like to get the Air as a small and portable, easy to carry machine for rounds and writing up patient notes, consult notes, etc. It will not be my primary machine, but hopefully a worthy road-warrior. I will be using Windows for the clinical electronic medical record application, but other than that, all other use will be on Mac OS X. Based on this, would you recommend going with the Rev B or Rev C. Money is tight, and this will be a gift from one of my mentors, but I do want to get the biggest bang for the buck. If the only difference between the two machines is processor speed, I can't justify spending 200$ extra just for a 0.27 GHz gain.
I have a 2007 White Macbook 2.4 Intel Core 2 Duo Laptop. I purchased it in June 2007 and this is my current battery health. Check the picture below, It's pretty amazing and I don't know how I did it. I'm on my computer almost everyday. Any idead on what I did to get such great battery life after three years? I know people with newer MacBook Pros that have terrible battery life after a year and a half.
View 1 Replies View RelatedI bought a 1st Gen Macbook Air in March of this year and I recently have noticed that my battery is not lasting as long as it should, so I checked iStat and it said that my battery life is at 86%. I also have a 12 inch powerbook G4 that still has the same battery it came with and the battery life is also 86% and it is more than five years old. Is this normal for the Macbook Air or should I take it into Apple?
View 10 Replies View RelatedI have a quick question about the battery in early 2008 MBP. The laptop is 13 months old, with 273 load cycles, and it is already down to 72% of original capacity. I've read that it should still have 80% at 300 cycles. Is this normal, or is the battery dying faster than it should? I don't suppose there's anything I can do short of buying a new battery right??
i Have a 15 inch unibody MBP (the one with the 4 hour battery) and since I got it, iv realised iv never gotten close to 4 hours on it, even just with web browsing.
I tried the battery calibration thing on apples website but that didnt help at all. On a full charge if I check the battery it says I have 2:45 left, sometimes 3. thats not even close to 4 hours.
also, I can NEVER finish a movie all the way through. If im watching a movie, my battery will usually die about an hour and thirty/fourty five minutes in and I always have to plug it in to finish. does anyone else have these problems? or is this just how its supposed to be because it kinda sucks
My mac is on the more battery life setting also, and was purchased late april 09
I have a late 2008 MBP 2.66, and I just started using my wireless router and was doing some simple web surfing/ email, when I noticed my full battery was only good for a little over 3 hrs! What the F!? I usually have it plugged in, this is the first time I have been using it (for a long period of time) wirelessly. It is a refurb which I bought in Oct. Any idea if I should have the battery replaced?
View 2 Replies View RelatedI got my MacBook Pro on the 1st of September and I'm a bit worried about the battery life. At the moment the screen brightness is one bar and bluetooth is off, which is how I normally have it and the battery life time estimate keeps changing quite a lot. 5 minutes ago it said 5:11 left, and since then it's changed to 7:30, 7:58 and now it's saying 6:50 and is now on 95% and 8:03. I'm not doing anything differently and I don't know why it's doing this.
View 3 Replies View RelatedWould be extremely interested in hearing about the battery life of the MacBook Air either the 13.3" or 11.6" from someone using it firsthand.
View 1 Replies View RelatedIm a little confused, is the Air Battery life that good? I've taken the following claims from the Apple website. MacBook Air - Get up to 5 hours of battery life on a single charge on the 11-inch model and up to 7 hours on the 13-inch model. 13" MacBook Pro - The new energy-efficient architecture in the 13-inch MacBook Pro gives you up to 10 hours of battery life on a single charge. I understand that Steve Jobs advised that they were using a better way to measure battery life for the Air that reflect real world usage better (WiFi Browsing I think?) so how does this compare to the MBP range? I guess the MBP battery claims were made using another older method, so any thoughts on how the Air's battery life compares to other PC's and Mac's?
