Hello, my Asus x550za suddenly shut off and will not boot. No power, no lights. I’ve verified 19 volts coming through the AC adapter, power jack and power jack port. I noticed that one side of the CMOS battery holder came unsoldered from the motherboard and is hanging. Could this have caused the laptop to suddenly turn off and to not be able to boot?

Thanks.
