hilfe! mein nagelneuer g5 dualpro startet nicht mehr. wenn ich auf den startknopf drücke heulen nur einmal kurz die lüfter auf. kein bing oder irgendwas. kann das an einer leeren batterie liegen?

Neuer G5 leere Batterie, sowas sollte es wohl nicht sein

Schon mal kontrolliert, ob Alle Karten und RAM-Riegel ordentlich sitzen?

heiko

vielen dank werds mal ausprobieren.

<br>Auf dem Motherboard des G5 ist ein kleiner schwarzer Knopf, der resettet so ziemlich alles. Drück den mal. Da kannst du nix verkehrt machen!
<br>
<br>Ich schau grad mal wo der sitzt ....

Resetting the PMU on the Logic Board
<br>The PMU (Power Management Unit) is a microcontroller chip that controls all power
<br>functions for this computer. The PMU is a computer within a computer. Its function is to:
<br>• tell the computer to turn on, turn off, sleep, wake, idle, etc.
<br>• manage system resets from various commands.
<br>• maintain parameter RAM (PRAM).
<br>• manage the real-time clock.
<br>Important: Be very careful when handling the logic board. The PMU is very sensitive and
<br>touching the circuitry on the logic board can cause the PMU to crash. If the PMU crashes
<br>and is not reset, the battery life goes from about five years to about two days.
<br>Note: For the location of the PMU reset button, see “Logic Board Diagram” in the Views
<br>chapter.
<br>Many system problems can be resolved by resetting the PMU chip. When you have a
<br>computer that fails to power up, follow this procedure before replacing any modules:
<br>1. Disconnect the power cord and check the battery in the battery holder. The battery
<br>should read 3.3 to 3.7 volts. If the battery is bad, replace it, wait ten seconds, and then
<br>proceed to step 2. If the battery is good, go directly to step 2.
<br>2. Press the PMU reset button once and then proceed to step 3. Do not press the PMU
<br>reset button a second time because it could crash the PMU chip.
<br>3. Wait ten seconds before connecting the power cord and powering on the computer. If
<br>the computer does not power on, there is something else wrong with it; refer to the
<br>“System” section of “Symptom Charts” in this chapter.
<br>Note: The above procedure resets the computer’s PRAM. After resetting the PMU, be
<br>sure to reset the time, date, and other system parameter settings.

<br>Hoffe das hilft dir weiter!!
