Hi,
Whenever I disconnect the power cord of my MacBook, the OS shuts down within 2-5 seconds. The battery is installed and it has a 80% health and it has 185 charge cycles. I've been experiencing this strange behavior after two days of installing (Secrets Preference Pane). But I'm not sure if it was behind the problem. I even uninstalled Secrets preference pane but the problem still exist.
At first I though the battery is dead, but for some reason I tried running the laptop later on the battery power and it ran for whole 2+ hours until it was fully discharged. I then charged the battery fully and used it again and it was working like a charm. But later the problem returned and the MacBook shuts down whenever it is not connected to the power cord. If the battery was dead, then how come it runs without a problem sometimes? also the health indicator shows that the battery is 80% healthy and the charging cycles is not much and whenever the system shuts down, the indicator on the bottom of the battery shows that it is fully charged.
I don't know what is causing the problem, and why sometimes the problem arises and sometimes it goes away.
I am using a 2007 white MacBook with the original battery (provided with the laptop). I am running Mac OS 10.6.2.
I tried several solutions such as:
- Cleaning the battery and MacBook ports.
- Resetting the PRAM.
- Fully discharging the battery and then fully charging it.
But it seems that I am not able to resolve the problem. I would appreciate any provided help.
Thanks,
