No "Low Battery" warning on new (November 07) MacBook - Kernel Panic

thx J-a-x this will be great...are you sure that this is the error log after it crashed? can you verify it with the date + time you got kernel panic after low battery warning?

I guess its better if you can sent me your system profiler(or maybe also the panic log) file through email. So that the engineer can work the problem for exactly the same system+panic log combination.

send to:
onetobenl <at> yahoo.com

Because actually I have to send the file through "apple bug reporter" website from my account...

Thanks a lot J-a-x...

Hi,

This is really annoying thing. I also have the same problem with my new macbook. I had sent it back to Apple and had a second one, which had still the problem. I do not know why I have to waste my time in "testing" a product. We pay, and they should provide a product we could use. This is annoying issue when I use MacBook. So, I decided to get refund by sending it back, and I will wait until this is resolved somehow. During that time, I will use my old powerbook.

Please, update anything about this.

Thank you!

Update: Today I really confident that with the new battery my MB is healed...I tried using my MB again, after "low battery" warning I thought it will go to "sleep" mode but it wont!!!

I got another kernel panic again....aarrgghhh....But this time my MB is going down pretty hard....I can hear from the way my HD spin...

I've sent my panic log + full system prof to apple hoping for a solution.

My MB is pretty new. Its 1 week old, so I only have 1 more week if I want to return it. IMHO this is not a small problem, it really need to be fix. I really can't work like this, because I have to be constantly looking at my battery percentage and have to running to power outlet to charge it. If I dont find power outlet & dont have time to save all my work then it will be lost...yeahh greattt....Its just not suppose to be like that...

My Solution: I've decided to call Apple and ask politely for refund. UPS will pick up my MB within 2 days...yeah this is pretty sad. I'll hold off for a few weeks with buying a MB or maybe have to consider buying a MBA for my wife. She just got another job and have to returned her old company laptop. Right now she didnt get a laptop from her new company because of confidential reason. So I might open a new thread asking for advice about what to do... =)

I'll still update this thread if I get any reply or new solution/update from apple engineer.

webman2k: Hai webman2k you're the one who started this thread. Is it possible if you can edit the topic title and add a words like -"No Low Battery" or after "Low Battery" warning ..... Kernel Panic/Shut down-.....? It will be more clear to people that having the same problem.

Of course only if you want to change it...thats ok if you dont want to

Is there anybody who have installed Mac OS X 10.4 Tiger in a new MacBook (less than a month old)? I was one that could NOT use a new MacBook (less than a month old) and got refund. I am wondering if there is anybody who does not have any "No safe sleep on a low battery" problem with Tiger on a new MacBook. If there is even a few people like that, I will buy a new MacBook and install Tiger.

I know this is weird, but I need a MacBook soon for my work. I guess Tiger is still good. I think that the only feature of Leopard that I would like is TimeMachine that is for automatic backup. I think that I can live without that and have some other backup system in Unix command.

Please, ... could you(?) respond if there is no "No safe sleep on a low battery" problem with Tiger on a new MacBook?

Thank you,

First thing I did was plug it in to charge as I started configuring software. Once it was fully charged, I pulled the plug, and began using it on battery. My plan was to calibrate the battery, by running it all the way until it forced a sleep, then shutting down and plugging it in again, as Apple recommends.

Problem is, I never got the "Low Battery" warning, or even the sleep warning. At around 10 minutes of power left, I simply got a kernel panic. A few seconds later, the laptop just switched off.

I plugged in again for a few minutes, then ran it down again to see if I could reproduce the error, and I did get the low battery warning.

The next time the battery ran down, it gave me the kernel panic.

Is this happening to anyone else? Is it a new MacBook problem, or a leopard power management problem? I'm having no other issues at all with the MacBook or Leopard. Any help would be appreciated.

Thanks!

Calibrating the battery is bad for the battery, unless its running horrible. For a brand new laptop you should not do that! For a 2 year one its ok it it causing trouble. You pretty much messed the laptop and battery up. Bring it back for a new one and don't screw it up!

Read through this thread and I think you'll find your answer, we've been discussing this for a while now. Obviously other people are having this problem or else we wouldn't have posted 90 messages about it in this thread!

I got Apple to swap my battery for a new one and it's been working fine ever since. That doesn't seem to work for everybody though.

By the way, Apple says,
"Repeat the calibration process every two months or so to keep the battery fully functioning. If you use your MacBook or MacBook Pro infrequently, it’s best to recalibrate the battery at least once a month. If you purchased additional batteries, repeat the calibration process with those batteries as well."
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh2339.html
So I don't think its such a bad thing to calibrate a new battery.

Ok...I got an email from the engineer.

So the engineer concluded, after I sent my kernel panic log, that this is not a bug but rather unit-specific error.

Its a machine check panics, indicating hardware error and my MacBook needs to be serviced by an authorized Apple dealer.

Ok so at least I made a correct decision by asking for refund...

Interesting. I hope that's not the case with my machine. Mine started working fine with a new battery but I haven't let it run down recently to check for a kernel panic. I did test it 3 times though when I got my new battery. My tests were generally with low power consumption (browsing the web, email etc). I wonder if the amount of power consumption effects the crash. Ie: would my machine crash again if I ran the battery down while watching a DVD...

My early 2007 machine, still running 10.4.11, has been exhibiting this behavior since it was a couple months old. So I don't think it's a Leopard issue.

Yep - another vote here for the 'No Battery Warning Light - Just Shut Down With About 20mins. of Juice Showing'.

As the battery and MacBook are perfect in every other respect, I always thought it was a Leopard issue and was keen to see if anyone had cured the problem by downloading 10.5.2?

My advice from Apple support was:

Reset the PRAM (insert yawn smiley)
Re-install the system software (insert the can't be bothered smiley)

There's masses of people with this problem.

I've upgraded to 10.5.2 & had the random shutdown at 18% twice today.... After having it several times in the past week or 3 under 10.5.1.

I'm not happy, but at least I'm not alone.........

Same problem here. No warning and then it shuts down suddenly.
So, what's the solution for that (other than replacing the battery)?
I have Battery Update 1.2 on a Intel Core Duo and 10.4.11.

Thanks
