Bonsoir,

Voilà depuis quelques jours je ne peux plus l'éteindre c'est G3 qui tourne qui tourne sous 10.3.9.
Menu pomme éteindre et là pas de réaction
par contre suspendre l'activité fonctionne.
est-ce grave docteur ?:confused:
quelqu'un a une idée pour résoudre çà
merci de votre aide
 
reset de SMC. Voir sur le site Apple en fonction de la machine
 
Reset CUDA/MPU

C'est marqué pour les ordinateurs à processeur Intel, mais je pense que la technique fonctionne aussi pour les G3... À Vérifier.

Edit: Autant pour moi, merci daffyb
 
bonjour,

c'est un imac couleur indigo 450Mhz...
google est ton ami... un peu de recherche n'aurait pas fait de mal :hein:
The PMU Chip
The PMU (Power Management Unit) is a microcontroller chip that controls all power functions for the computer. The PMU is a computer within a computer. It has memory, software, firmware, I/O, two crystals, and a CPU. Its function is to: •Tell the computer to turn on, turn off, sleep, wake, idle, etc.•Manage system resets from various commands.•Maintain parameter RAM (PRAM).•Manage the real-time clock.
Important:
Be
very
careful when handling the main logic board. Remove the battery when handling the logic board so the PMU is not affected. The PMU is
very
sensitive and touching the circuitry on the logic board can cause the PMU to crash. If the PMU crashes, the battery life goes from about five years to about two days if the PMU is not reset. Refer to the next topic, “Resetting the PMU on the Logic Board” for the procedure. Many system problems can be resolved by resetting the PMU chip. The PMU reset button is located on the right side of the board, refer to the logic board dia-gram below.
Resetting the PMU on the Logic Board
Resetting the PMU (Power Management Unit) on the logic board can resolve many system problems. Whenever you have a unit that fails to power up, you should follow this procedure before replacing any modules. 1.Disconnect the power cord and check the battery in the bat-tery holder (BT1). The battery should read 3.3 to 3.7 volts. If the battery is bad, replace the battery, wait ten seconds, and then reset the PMU (refer to the next step). If the bat-tery is good, go to the next step.2.Press the PMU reset switch (S1) once on the logic board and then proceed to step 3. Do
NOT
press the PMU reset switch a second time because it could crash the PMU chip.3.WAIT ten seconds before connecting the power cord and pow-ering the computer on. If the computer powers on, go to the next step. If the computer does not power on, there is some-thing else wrong with the computer, refer to the symptom/cure chart, “No Power” in this chapter.4.Run MacTest Pro and return the computer to the customer.
Note:
This entire procedure resets the computer’s PRAM. Be sure to reset the computer’s time, date and other system parameter settings before returning the computer to the customer

je vous remercie tous de votre aide, tout est rentré dans l'ordre:up:
sur les conseils d'un internaute d'un site d'entraide mac j'ai viré ces deux fichiers com.apple.loginwindow.plist et loginwindow.plist, et çà fonctionne à nouveau.
merci encore
Bonne journée
