No It just lits up and turns off. I dont think it is a pattern.

Try removing one stick of ram if you have two and test one stick at a time in each of the two ram slots. Then test the second stick of ram in both ram slots this will tell you if you have bad ram or a bad ram slot. if it still doesn't work you need to consider getting out a multi meter and tearing open your computer and testing the circuit board starting at the power outlet and working into the board

I have a T430 with the same issue. LEDs (power Fn F3 ) are blinks one but the laptop does not turn on.

I triedtoclean the connections, remove the batteries....no change.

Once i removed the RAM and the unit booted up.

So the issue is the following : it works with no RAM, but it does not work with installed RAM.

The problem is the same with the old and a brand new RAM also.

Any idea?
