PowerPC :: Disable Date & Time On An IBook G4 800MHz?
Mar 14, 2008
I am working on a hardware hack with an iBook G4 800MHz where I can only power the iBook with the AC Adapter--NOT using the battery. When the compy is turned off and turned back on, I am getting this huge error message on the display that my time and date are wrong.
I gather there is no battery on the MB that sustains the internal clock--the compy uses the powerbook battery to keep the clock up to date?
Is there any way to set the system software to bypass or ignore the time and date? This computer is not connected to the internet, and time and date are irrelevant to my application.

My school has ~15 iBook G3's(600 MHZ, 128 MB RAM, OS X 10.2.8) that are suddenly unable to hold the date or time. They are plugged in constantly, batteries in, and are always on. I know that with the Pismos, there are PRAM batteries that you can replace, but if I read Apple's support pages right, there aren't any in the iBooks. How does this happen? How easy is the fix?

I have been viewing the forums for the past few months and have finally joined MacRumors as I have purchased an ibook G3 (first mac). I love it to death, it is so portable and even runs like a champ considering it is almost 4 years old. The ibook has a 800MHZ G3 processor along with maxed out ram at 640MB. Anyway I am planing on buying an TV before school starts up again and would like to encode my dvds to h.264. I was wondering if my computer can handle this task. BTW I would need to buy a dvd drive for my computer along with an external HDD. My other option is to buy a friends Powermac G4 with dual 1GHZ processors(he is selling it at $250) it already has a dvd drive and two 200GB HDD so that will save me ~ 150. As I am new to macs and would like to know if the Powermac will significantly make a difference in encoding times or should I just stick with my ibook and save the $100?

I've got a G4 iBook here that is really really slow. It's running Mac OS 10.3.9, has an 800Mhz G4 CPU, and 1.12GB of ram (Built in 128mb + 1GB upgrade).
Activity monitor shows over 800mb of ram free, and about 16000/0 page ins/outs.
The CPU is also about 80% idle.
Something is fishy. There is only 6GB of free hard drive space.. but I don't see how that could cause this nightmarishly slow performance. It takes 5 minutes to open a folder sometimes! Could it be bad ram? Malfunctioning hard drive? Does it sound like a hardware issue or software issue?
I also noticed that there were a few folders in the hard drive such as "Previous Systems" "Rescued files" and "Damaged files." I already trashed "Damaged files" because it was just a bunch of random crap that no one would need and it was taking up space.

I have a G4 iBook - 1.07Ghz, 768Mb RAM, Panther - that keeps giving me the swirling beachball of death depending on the date setting on preferences. If I set the date to 2004 the machine runs fine, but if the date is set to today or (I'm not sure of the exact date) after 2007-ish the thing keeps freezing.
Also, after the freezing troubles I installed Ubuntu and it ran perfect with the correct post 2007 date.

I'm running Leopard on my iBook G4, 1.33GHz. I am using it with an external keyboard, mouse, and monitor, but the "clamshell mode" is not supported on iBook G4s. I've tried Sleepless and InsomniaX, but they both don't work.

I am on Tiger 10.4.11 on Mac Book Pro Intel duo. All updates except for Parallels installed. Have run permissions repairs and preferential treatment. Tried to delete preferences for system ... Every time I try to uncheck the box marked or open the Date and Time preferences, it freezes and have to force quit.

My Powerbook G4 Titanium is running OSX Tiger and will not open the Date & Time preferences - instead it gives the error message 'System Preferences closed down unexpectedly' with an option to send info to Apple.
This is an issue because the date has reset to 1970 and when I start the mac the time is always 04:00. I tried leaving it connected to the wi-fi overnight to see if the time servers would do their thing, but no luck.

So I shut down my computer earlier today for the first time in weeks. I restarted it and then left for a few hours for dinner.
I come home and I look at the last time MobileMe Sync and Time Machine did their things. They say they did them at 7:45. I look at the clock on my cable box and on my iPhone, both say 6:45.
Weird that the MacBook's time is wrong. I go into Time Date settings. I see that when the MacBook does the "Auto locate where you are so that we can set the appropriate time zone, etc. the MacBook things I'm in Rexford, Idaho.
I haven't been to Idaho in about 25 years, and my MacBook has been sitting in Southern Kalifornia for the last one year since I bought it.I've tried to have the MacBook auto-locate again, and it keeps finding me us in Rexford, idaho.

I'm running OSX 10.5.8 on a G4 iBook. Somehow my Time & Date files got corrupted which prevented me from getting on to the internet. When I discovered the problem, I threw them away, thinking a restart would create them again. I was wrong.
Now my computer doesn't know what time or year it is, causing various problems. I don't have back-up 10.5 disks to extract the time & date package.Can I download a replacement anywhere?
Or can someone email the files to me? I don't know what they're called but, if you search time and date, there are only two (and please tell me what folders they're in too)

Starting yesterday, I cannot load Time & Date (either from System Prefs or from the menu bar). I get the beachball and I have to Force Quit System Prefs.
I tried Repairing Permissions and rebooting but it didn't help.I tried deleting .plist entries (as per a related thread on the Internet) and rebooting and that didn't work either.I tried logging off and logging in with another account and the problem is still there.I hope I can get some help because it's driving me nuts. I travel a lot and need to change my time zone. If you need a crash report from me, please tell me how to get it from Console bc I don't know where to look for it!
P.S. I am using old OSX 10.4.11

Just wondering if anyone's tried to run Mac OSX 10.5 on their 800mhz G4 and how the performance is (good/bad)? Obviously the cutoff is 867mhz.

Now, my poor little G4 was just standing there. After a lot of fumbling around, restores, it finally has regained life, running Tiger etc.
Now, I wanted to install Leopard, see for myself what I would prefer, and it would allow to tether wireless internet connection through my iPhone to the G4. But I need Leopard for that, Tiger is too old.
So, after Googling, I found out that if I put my Intel into Target Disk mode, I could use it as external DVD reader, seeing my G4's reader is dead as dead can be.

My brother has a second gen, 800Mhz eMac (the one that could be overclocked to 1.33Ghz - the earlier PC133 ram model). Since about 1.5 mths ago, when he powers it on, sometimes it will not power on, and other times it will give three beeps (diagnostic pages say bad RAM) and a flashing power/sleep light in unison with the beeps. Did this vintage suffer bad caps? I recall that it was only the 1.25Ghz model that had bad caps, but I could be wrong.

I have an eMac 800mhz and I'm having trouble discerning whether it's an "early" build which needs the original AP card or a later build. What exactly am I looking for in the system profiler to tip me off?

Purchased this notebook used, but very nicely cared for, excellent condition. I ran the Apple Hardware Test and everything passed including the logic board.
The battery has 500+cycles. The problem is laptop shuts down at 50% or less of battery. Clock is wrong at startup but is correct a few seconds later.
Runs forever and very nicely on ac power.

I'm feeding the headphone output of my G4 1.1 ibook to an amp. I need to prevent the built in mic from passing its audio to the output. However, there does not seem a way to do this in preferences-ie to switch off the mics without also turning off the output volume. Can the mics be disabled some other way?

My date and time resets each time my mac sleeps or is reset or if I open date and time options. It keeps sending emails of my old reminders from 2008/2009 from ical and my to-do list emails me its reminders. This happens every time I open my comp or even just open date and time options. I also get the ical reminder notification that pops up freezes on my screen.

Okay, so I am running OSX and Vista on Bootcamp. I have noticed that when I use Windows or just even restart OSX that my date and time changes. Today it changed to March 1, 2000. I am curious as to why this happens. My time zone is fine. I think it has something to do with the Vista configuration.

We got a refurbished Alu MB for an intern and the time is not displaying properly. If I check the "Set date & time automatically", the digital and analog clock is showing different times. See picture. Also, when I go in Time Zone, I set Eastern time, it will set it, but when I go back to preference, it sets back to GMT.
It's running 10.5.6 if that helps.

I have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.

My brother's iBook G4 (800Mhz, First Rev) has completely splattered itself and we're getting a new Macbook for him under insurance. My iBook G3 (White, 900Mhz G3..the last G3 Rev of the iBook) has a failing hard drive.
Now, could I swap out those two drives, at least to recover stuff? And is there a specific method of opening up the iBook G4 so that I don't break stuff (I've already messed with my G3..and ended up with a dozen extra screws ^_^
Mainly the aim is to salvage the hard drive and swap them out; replacing my faulty iBook G3 one with the iBook G4 one which is perfectly fine.

Right now I have a G3 iBook (900 MHz, 640 MB RAM, Combodrive, 40 GB HDD). I'm looking at a G4 iBook (1.2 GHz, 768 MB RAM, Superdrive, 60 GB HDD).
How much faster would the G4 be over my G3. I figure that after selling my G3, the G4 would only be another $200ish on top of it. Would this be worth it?
