Diagnostic card code after powering on the motherboard
After the motherboard is powered on, the diagnostic card code does not move. The 00 or FF side indicates that the motherboard CPU is not working. Next, we need to cut off the power and remove the CPU fan for a good CPU. Hold the CPU by hand (the best use between the finger and the CPU) The hot things are separated to avoid burns.) Press and hold the power supply slightly. If the diagnosis is still unresponsive and the motherboard is still not working, then the CPU base is discharged and the next step is to determine if the CPU circuit is faulty.
First of all, we should know the trend of the CPU power supply circuit of this motherboard. Under normal circumstances, the CPU power supply circuit layout is reasonable and will not be in other places around the CPU, so we also need to know that the CPU is red 5V power supply and then connected with a black meter pen. Red 5V interface, red pen connected to the CPU auxiliary power supply four-corner interface (multimeter modulation buzzer can be) when the multimeter will make a short call to indicate that the circuit is no problem.
Then put the black test pen on the CPU auxiliary interface pin, and the red test pen slides on the U chip next to the CPU. If there is a short call, it will stop immediately. At this time, the pin on the chip is the CPU5V power supply pin (this U chip is the power supply). Management chip) Next, two pairs of FETs next to the side CPU (effect transistor cannot be short-circuited with a multimeter twice. If it is found that the three pins are energized to each other, the effect transistor is broken or damaged and replaced) Next, measure several capacitor resistors in the CPU socket. If the power is on, the CPU power supply circuit is no problem. The CPU circuit is often damaged (two pairs of effect transistors, power management chip, capacitor).
3. The overall detection of the motherboard, plug in the diagnostic card, first add the CPU, then add the memory, plus the discrete graphics card, the display code starts from OO or FF, once 01, C1, 24, 25, 26, etc.
