powerbook keeps going to sleep

[Danny.hajicek]

That's pretty much it: open terminal and copy and paste these commands exactly one line at a time:

cd /
sudo mkdir kext.backup
sudo mv /System/Library/Extensions/ApplePMU.kext /kext.backup/
sudo rm /System/Library/Extensions.kextcache /System/Library/Extensions.mkext

...and reboot.

This creates a folder called kext.backup, moves a folder called ApplePMU.kext to this new folder so it will no longer be in the kernel, then removes the kernel extension cache so the operating system will check through extensions again.

To put power management back in:

cd /
sudo mv /kext.backup/ApplePMU.kext /System/Library/Extensions/
sudo rm /System/Library/Extensions.kextcache /System/Library/Extensions.mkext
sudo rm -Rf kext.backup

...and reboot

Same thing, but in reverse. Be warned, lots of things don't work right without power management. Most notably, you will have to hold the power button after you shutdown to get the computer to actually turn off.

Also, I, personally, wouldn't tell apple I did this. It doesn't harm anything, but they don't like people tweaking in the system.

Hello

Ok, so I turn off power management via terminal. Reboot via the restart command in the finder then hold down the power button to actualyl turn off the computer and then again to turn it back on.

Now it should stop going to sleep so that I can back up my data.

Then I turn on power management via terminal again and then reboot as per normal.

Have I got it right?

thanks!

Also, do I need to worry about the IOICLM7.ktext??

 

[Danny.hajicek]

Pretty much. The restart will work the first time, because power management will be functioning until the computer boots after you've disabled it. It's the second restart after power management is disabled that might not work quite right.

 

[Danny.hajicek]

You don't need to worry about IOI2CLM7x. That's the software workaround for this hardware problem. You are going to convince apple to replace the defective trackpad sensor in the top case ;-) Those of us without a warranty left aren't so lucky.

Hi all,

If you have an external drive take it with you to the AppleStore...

...explain the problem, about not being able to back up because of sleep issues.

Then ask them to stick your PowerBook in to Target Disk mode, then copy all the data from the PowerBook to your external drive.

Then let them run ASD and see if you have a defective sensor, if you only have 6 days left get to the Apple Store !

Ric

(Welcome Danny !)

 

[Danny.hajicek]

Thanks for the welcome. That is a good plan, I forgot about target disk mode.

For the record, I ran the hardware test on my laptop (which definitely has a defective sensor) and all hardware passed the test

Hi there Danny,

did you run the Apple Hardware Disk...

Apple Engineers have access to 'different' diagnostics software that will pick up the defective sensors.

Why the AHD doesn't, I don't know !

I have run both AHD and ASD (Apple Service Diagnostics) on a suspect PowerBook and only ASD picks it up !

Ahhhh, that's not really fair of them to keep that from the users

Hello,

Ok, I am going to bring all my stuff down to the apple store tonight.

Thanks a lot guys!!

I really like this forum

I know !

If you sign up for the AppleCare Technician Training, (quite a few $$$) then you get access to it !

It isn't just one 'disk' there are versions for every different Mac...

;-)

Hi All,

I've sent my computer in to the apple shop. I asked them to switch my computer into target disk mode, but they said that they could not do this because I did not have another computer to transfer my data to...?? So I copied the files I really needed to my external hard disk myself (the computer stayed awake for the whole time!) and then sent it in for repairs. They promised me that they would call me if they needed to go into the harddisk and that they probably would not have to....

Just out of curiosity, have any of you apple users found the staff at apple stores somewhat unfriendly? I have been to the apple store here several times and have always encountered unfriendly and unhelpful staff. Some of the other users here agree about the staff being unfriendly and I am wondering if it is a world-wide phenomenon.

I'll keep you guys posted on my mac and its sleep issues... I am so glad I got it in just before the first year warranty was up!

Hey iryskel

Just out of curiosity, which Apple Store do you go to?

 

[iryskel]

umm.. I hope I did not offend anyone re: the unfriendly staff at apple stores... Also, not ALL of them are awful, a few are nice, but generally they seem unfriendly/unhelpful.... or maybe I have just keep catching them at really bad times.

anyway... have a good day!!

 

[iryskel]

would it affect my computer that is at the apple store right now? haha....

the apple store in singapore...

 

[searay345]

Oh no, I am not offended. I was just cirious. I am a specialist at one of them and I know my store is really friendly.

 

[iryskel]

that's great! pity it's not the store i go to though! heh.....

It works for me, no problems with sleeping at all so far.
