I have 2 question first is when do the powerbook G4 15in 1.67ghz fans turn on like what temperture.
My second question is my PB G4 doesnt charge we replaced the battery about a year ago and replaced the charging adapter and that power brick but its say it doesnt charge and give a battery symbal with a plug on it in the right hand corner. please help me figure out this problem thank you
The Service Manual has no info about what temp turns on the fan.
Here's what is says about the battery chargnig.
Battery won't charge
1. Make sure that power adapter connector is fully inserted.
2. Remove any connected peripherals.
3. Try known-good power outlet. Green or amber light should glow at power adapter
connector.
4. Try known-good power adapter and power cord.
Note:
Verify that power adapter connector glows amber or green. If the power
adapter light is green, turn over the computer and press the battery button. One to
five lights glow to show the battery’s level of charge. One blinking light indicates that
the battery does not have sufficient charge to turn on.
5. Remove battery and reseat it.
6. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
7. Update to Mac OS 10.2.4, or boot from external device with 10.2.4.
8. Replace DC-to-DC board.
9. Replace logic board.
Battery won't charge completely
1. If battery reaches 96 percent and doesn’t charge further, this is normal operation.
Refer to Knowledge Base article 88344 "PowerBook G4, iBook: Battery Does Not
Show Full Charge in Mac OS X".
2. If battery charges to 95 percent or less and stops charging before reaching 100
percent, replace DC-to-DC board.
Press the small button on the battery assembly. Do any of the 5 green indicators illuminate?
Cheers, Tom 😉
The only observation I have is that my 1Ghz PowerBook's fans kick in between 135F and 140F based on the utility Temperature Monitor. You can get that utility at no cost here:

It puts a readout in the menubar and you can watch it and note at what point you head the fans kick in.
