AC adapter versus DC-In board versus Logic board?
I have a 12" 1.33 GHz ibook G4 bought in 2006. My battery was not part of the battery recall program.
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1790
Remaining Capacity (mAh): 0
Amperage (mA): 0
Voltage (mV): 6192
Cycle Count: 0
AC Charger Information
AC charger (Watts): 65
1) I had the AC adapter replaced in 2008 after dropping it on the floor a couple of times.
2) The battery stopped holding charge sometime in 2010 and I've been relying on the AC adapter ever since.
3) The clock on my iBook has been switching to Jan 1st 1970 since 2008.
3) My laptop has been shutting down insidiously since the last two weeks regardless on what program I'm using. I don't hear the start-up chime anymore. The color on the power cord insertion switches from orange to green intermittently when the battery is secured. It's a constant green when I remove the battery but switches to orange around shutdown.
I am technologically challenged so I apologize for any unwanted information I may have revealed above. But, I'm assuming the battery is done for. After resetting the NVRAM and PMU, the clock stopped acting up. However, the problem returned once I unplugged and plugged the adapter.
I'm very determined to solve this issue. And I want to thank this forum in educating me! It's absolutely phenomenal! I'd appreciate any help in reviving this machine.
Your clock (along with other key user settings like screen resolution and printer) is "maintained" by a "backup battery" - except that model laptop has no backup battery, it used the "normal" battery. That explains your time/date "reset" when you had no battery in it, and why the "problem" (it's not really a problem is a software design to tell you lost all power) returned after the NVRAM & PMU reset.
The sudden shutdown could be due to myriad of issues. If you hear fans kick in before the crash, overheating. No fans, could be your HD (back up any important files now), or other failing component.
Repeated sudden shutdowns can screw up the master boot directory causing shutdown problems when data is attempted to be written to the HD. Boot from your install disk and run TOOLS Disk Utility:Repair Disk, and then as long as your there, Repair Permissions.
Yes your battery is dead... it's not normal for a used battery to report 0 cycles, and obviously it's no longer charging.
