Hello all, turned on my t430s started doing some basic work. Less than 5 minutes after turning it on, I heard a pop and laptop shut off. No power or any lights with the a.c. plugged in or the battery. I pulled the battery and psu and held the power button for 10 seconds then retried to start the laptop with both plugged in. Still nothing. PSU on the voltmeter showed 20.1v DC, so that looks to be in spec with the 20v label. Battery was 86% and charging at the time. Any ideas besides a fried laptop?
