T430s: Doesn't accept AC power, status leds aren't working
T430s: Doesn't accept AC power, status leds aren't working
Hi all,
I had to disassemble my T430s (due to an issue with CPU fan), and when I assembled it back, the microphone, camera and indicator leds seem all to be dead.
Seems very likely that the issue is with the LVDS cable (the led cable as shown in the hmm, I assume it's also responsible for the webcam and mic).
Visually it looks fine, and it is connected well. I barely touched it so I find it hard to believe I damaged the cable itself.
All other parts (including the monitor itself) are working fine.
And since I've posted this, I also noticed the laptop isn't charging at all from AC and won't run without a battery in. Well now it's a serious problem for me..
Any ideas on how to debug this? Are there any fuses that may have blown which would cause this?
Thanks

Is the DC sub board seated correctly? Does the thinklight turn on? That would be the dead give away.

How is the DC sub board supposed to be seated? I don't recall touching it at all.
Re: T430s: Doesn't accept AC power, status leds aren't working
If the thinklight isn't turning on then the DC sub board isn't fully connected. Or you somehow burnt out the DC sub board. Besides the DC plug, the data line for the webcam, and power for the thinklight come off that board.AlexTP wrote:The thinklight didn't turn on.tomatohat wrote:Is the DC sub board seated correctly?

That was it! Can't believe I missed something that obvious, I forgot to connect the board.tomatohat wrote:If the thinklight isn't turning on then the DC sub board isn't fully connected.

Thank you so much for the (very) quick response, you're a lifesaver!
Re: T430s: Doesn't accept AC power, status leds aren't working
I don't remember off the top of my head. But I think there's a physical switch on the DC sub-board that aligns to detect the ultradock insert/eject.AlexTP wrote:That was it! Can't believe I missed something that obvious, I forgot to connect the board.tomatohat wrote:
