The Power adapter of the 180 is not the same as the 165c and 180c. The 180 adapter was rated at 2 amps where the 165c/180c were rated 3 amps. Reference: http://support.apple.com/kb/TA32393?viewlocale=en_US Yes you can use a powerbook 165c/180c with your PB 180 but that isn't the original one that came with the laptop. >> You might be tempted to try to start the Mac Portable without a >> rebuild battery.

Booting the Mac Portable draws over 3 Amps to spinup the HDD. The older the hard drive gets, the more power it pulls to start ( = "stiction" ), especially those in the Mac Portable as they are notorious for failing. Don't forget that memory cards also take power... I have tested my own M5120 and M5127 this morning: the M5120 takes 3.1 Amps to start, the M5126 about 3.4 Amps With some luck the 3 Amps will take it but the power circuit of the Mac Portables were not designed to be started with a heavy power supply only through the DC socket. If you want to start it safely and don't have a rebuild main battery: use of Lab PSU, set it to 6 volts and 4 amps current and feed the power through the connectors of the main battery, with the battery cover closed.
