ASUS X45VD notebook is not powered on for repair

Machine model: ASUS X45VD

Malfunction: Notebook no booting

Maintenance process: connect the machine of the same trade, saying it is no booting, and unplug the battery.switch finds auto power off when the current reaches 1.0A water damage was found on the motherboard after disassembling.

This motherboard is an onboard 4G, and the customer has added a two-G memory. There is a particle water damage in the onboard memory, and Capacitor and corrode signs on it. First, I dug Capacitor, and then measured the ground value of memory Capacitor.

After conveniently measuring the Inductor, the standby value of 3/5V is very low.

However, I think it should be no problem if the current can run to 1.0A Let’s put it on first to see if there are any other problems. The memory water damage must be broken. I remember when I was in the field, the teacher said that ASUS could shield the onboard and only use the external device. So the onboard was shielded, inserted into the memory to test whether there were other problems, and Boardview searched DIMM_SEL.

Originally, the position of the resistor was 2/4/6. I moved No.4 to No.1, No.6 to No.3, then switch tried and the current ran to 0.8A (it turned out to be 1.0A auto power off, and then it was the same as pulling out the stand-alone one). Then, I went to a memory, and the current ran to 1.0A or auto power off. Is it incompatible to change the integrated BIOS to stand-alone BIOS? After brushing BIOS auto power off, customers don’t repair the onboard in a hurry, so just use it independently!

This is the position of the modified resistor, and three rows of resistors side by side above EC is the position where the on-board memory is switched.
