15" PB Won't run on battery only?
I just bought a new battery from Apple after running the PB on AC only for 2-3 months. The battery was at 30% and reached full charge overnight. The PowerBook works fine while plugged in. Battery charges and it sleeps/wakes normally. As soon as I disconnect the power supply the machine freezes - the screen goes blank and no keyboard response. To get it to boot up I have to remove the battery. If I try to boot it with just the battery the fans run at full speed for about a minute then it powers off.
I have tried the resetting PRAM NVRAM etc
Could the new battery be bad ??
Any suggestions gratefully received!!
Is this a good question?
