Today, I was browsing the web on my T430, with no peripherals connected besides the 90w AC adapter, when the screen went black, the fans shut off and the power button blinked at me twice. I sat there in shock for a moment and then tried powering it back on. The power indicator will come on and I'll hear the fan spin up, but within a half second the indicator is back off and the fan loses power. I tried removing the battery and using the AC adapter alone, using the battery alone, removing all power and holding the power button, but none of that has worked.
The configuration is as it came from the factory, except 1) I didn't have the DVD drive installed and 2) I have 2x8GB Crucial RAM sticks in there, for 16GB over the original 4GB. I will try reseating the RAM next to see if that works, once I can get near a screwdriver. I'm currently traveling and this is a bad time for a crash like this to happen
The system has the NVIDIA Quadro graphics option and a HD+ screen, if that makes a difference.
Hoping for your wisdom,
Danny
