So, I have a t440p that refuses to do anything. Upon powering it up, the keyboard lights come on, the fan spins for a second or two, the speakers hiss, and then the fan spins down. I've tried everything, reseating ram, resetting the bios, taking out everything except the cpu, and it still behaves the same regardless. Plugging in the charger makes the laptop turn on without pressing the power button, leaving it on makes the cpu go warm as if power is still being routed thru its internals.
Upon further investigation, the dvd drive seems to be spinning up, the caddy opens when I press the button on the faceplate, which leads me to suspect the power rails are present. What's more annoying is that I don't get any beeps at all. So is the mobo dead or what am I missing here?
Thanks in advance for any and all replies.
