Laptop motherboard repair does not take the code

We refer here not to go yard, provided that CPURST # and CPUPWRGD have been normal. If CPURST # and CPUPWRGD not normal output, not in the scope of this lesson. Note that some machines if CPURST # pull-up resistor is not connected to the VCCP, the general need to install the CPU to normal output CPURST
