XPS 15 9550 won't turn on after shutdown for several hours, can turn on only when plugging in the charger for at least a half day
Hello everyone,
It seems that my XPS 9550 has a motherboard issue. I have got this laptop for several months before this problem happen. At first, the power button needs to pressed twice before the computer can turn on. Pressing it once will only cause the button to light up and fans to start spinning for only seconds. Then, after about a week, the problem got worse. I have to static discharge the BIOS and charge the computer for about 12 to 24 hours to get it working again. The light indicator did show that the CMOS battery is dead several times, and I had the CMOS battery replaced, but still no luck. I have run the diagnostics many times, but everything seems perfect. And I can get into the OS once the computer powers on.

This post points out a similar problem, but I think it has nothing to do with the battery or most of the motherboard components.
Does anyone have encountered this before? Any advice will be appreciated.

I have charged the laptop for about 12 hours from last night. And when I turn it on this morning, the indicator LED in the middle of the bottom panel flashes 1 white following by 3 amber lights. This indicates a RTC power (CMOS battery) failure. Is there any chance I can repair this without replacing the whole motherboard?
