Re: HP OLED_EN Signal Missing 13-AW2007TU -DAX3ACMBAF0
Hi, on the CN3401 connector, check if you have the voltages on it.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Dell Latitude E5450 LA-A901P no BIOS voltage
So far we know with a charge of 100K ohms you have 3.3V on the pin 3 of UZ8 without the chip installed. With the original or an equivalent, you have zero volt on pin 3. My theory is the chip UE2 can't handle the current from the UZ8 and go directly to zero volt. With the EM5209 still on the board, cut the trace from the pin 3 and connect it to pin 2 so you will isolate pin 3 from UE2. You should have 3.3V on pin 14 of UZ8 and see what happens from this.
