Product description:
While we are repairing the computer (more of the main board).If it is suspected that the fault is caused by the cpu, the maintenance tool must be used for the cpu's false load.If we suspect cpu failure, we can't test it on a real cpu to the main board cpu socket, because it's easy to burn the cpu, after all, maintenance is risky.Moreover, it is in the absence of an accurate breakdown.Then you can replace the real cpu with a cpu overload to perform fault testing.
It's mainly used to measure whether the cpu's points and voltages are normal,It's normal before you get to the real cpu,The working principle is to connect the vid 0-vid 4 of the cpu,Control power supply ic's vid 0-vid 4 high and low level to realize output size management of cpu power supply
First, prepare a digital multimeter-it's all about it (on how to use digital multimeters)
-measuring the normal core voltage on the false load.
-reset on false load (reset)#(is it normal?
-measuring whether the clock on the false load is normal.(Oscilloscope is used to measure whether the clock on the false load is wave-free and the wave is normal)
-measuring the normal voltage of the pg signal on the false load.
-to measure whether the 1v reference voltage on the false load is normal.
-to determine whether there are three waves in the bottom c of the core supply on the main board (see if there are three waves in the bottom c using the oscilloscope).Reference to core power supply)
