A few days ago, laptop came power on but no display. Caplocks led blinks one time and continuously. I found CMOS battery is 0V and replaced with good one. And i notice that CMOS battey is drain very fast. When I replaced 3.3V New CMOS battery and a few minutes later it has 2.9V. I found RTC_RST# is about 2.3V (low). I think C367 is leak. So i Remove C367 and laptop run normally. Boot in windows and tested all fine.

After two days, laptop is no display again. Caplocks led blinks one time and continuously again. I try to find the fault but not success. And now laptop cannot switch on. Press power button and no response. Before press power key, Q19 Pin 3 (RTC_RST#) is 2.0V and Pin 2 EC_RTC_RST is 0V. After pressing the power key, Q19 Pin 3 (RTC_RST#) is 2.5V for a second and then 0V. Pin 2 EC_RTC_RST is 3.2V.

I also try to measure the current flows of RTC battery connector using DC Power Supply and Multimeter. Amphere consumption is about 0.030 mAmp. How can i find the fault?

check u9 - 32kHz?

I replace U9 with new one from this site. (https://www.aliexpress.com/item/3287627 ... web201603_)

For now, laptop sometimes switch on and sometimes not. When it's switch on, all voltages on all coil are ok, but no display (picture).
