HP CQ notebook is more intelligent, detecting the fan speed, detects the hardware temperature, and detects which hardware is not installed, and may reduce the failure rate of the motherboard, but also brought side effects.
HP CQ32 laptop motherboard with detection function, if the cooling fan is broken, do not turn, the motherboard will call the alarm when it is turned on, can’t enter the system, only change the fan, if you change the fan, don’t install the fan in place, Just let the fan try the test to turn around the heat sink, and it is not. Although the fan is turning, the motherboard will call the police, and the hardware is not in place, and the system cannot be allowed. Perhaps this intelligent monitoring will ensure that the motherboard is heat-dissipating effect, not in the case where the fan is not turned, or the graphics chip is burned. Of course, the fan is broken, it will make people mistakenly broken, and the hardware needs to be changed, and people who will be repaired by the laptop knocked the bamboo bar. In addition, HP CQ32 laptop motherboard has a temperature control chip, automatically shuts down when the CPU and display chip are too high to protect the normal operation of the hardware. However, the temperature control is too sensitive, and it will cause inconvenience to the user, and even false positives.
HP CQ42 laptop has a temperature control chip, as long as the user uses computer operation, the temperature is too high, the temperature control chip will work, sometimes generate a false positive, and the report temperature is too high, and the CPU and display chip The temperature is still not coming, how can there be too high temperature? Although the cooling fan is turning, the heat sink can also be scattered, but the report temperature is too high, can not boot, once entering the system, will drop the electricity, or the report temperature is too high, sometimes it doesn’t enter the system at all, the motherboard is also A problem. The temperature-controlled chip is too intelligent, or the smart temperature monitoring is lost, which has become a bad chip, affecting the performance of other hardware. When repairing, the temperature-controlled chip near the graphics card and CPU (generally near the small octagonal chip) can not make the motherboard will no longer false the temperature is too high, and can also enter the system smoothly. If you are troubles, or if you are afraid of the motherboard, you can buy a second-hand motherboard directly. Perhaps the temperature-controlled chip of the second-hand motherboard has been removed, or the temperature of the limit is not used, and it will not trigger the temperature control chip error, or maybe the second-hand motherboard temperature control chip has no aging, or more intelligent, of course There will be no failure.
Use the HP CQ notebook series must not be able to pay extreme use, this notebook uses the first generation I3, I5, I7 series CPU, plus AMD’s discrete graphics card, and the amount of heat is high. HP believes that the temperature control chip is required, and the hardware installation needs to be detected. It is necessary to detect the speed of the fan, otherwise it will burn the hardware to get lost. Unexpectedly, the more smart detection is, the more helping the unusual, perhaps covering the hardware technology is not mature, and the heat is high.
