            3.3V ALW mosfet Area PU4503 & PU4502 im compused for this? and why if inject (already plug the Supply Adapter) turn off.
            have Supply out of 2V only @ 3.3v ALW- if i turn on the switch to power on. unit turn light indicator only on after off
            checking the voltage on 3.3V ALW. have. but this Part no. PU4501 is heating up....

                  check PU4501: pin 3: 3D3V_AUX_S5??? if <3v3. check RTC_RST#, SRTC_RST# . I think error rtc block in haswell(cpu). replace CPU

                    Which one is the collector cap. I have a laptop with same problem, there is 2.3v instead of 3.3 on power button. Thank you in advance.

                      Same case, PU4501 still heating up, was it the CPU?
