Dell G15 motherboard LA-K453P can sometimes boot up and
sometimes not. After receiving the machine, it can't boot up most of the time. After checking the information, I found that the small resistor of the crystal array next to the graphics card of this computer will be poorly soldered, causing the graphics card to not be recognized. Unfortunately, my fault is not like this, but I still disassembled the machine to check the resistor RG71 and found that it was indeed poorly soldered. I simply repaired
the resistor. After repairing it, it can boot up normally every time
