BAD Capactive button

2013-03-31, 20:15 PM

My capacitive button on my C315 when bad and the screen keeps turning off.

I have to keep "touching" the on/off screen button to make it com eon for 4 seconds then off again.

NOONE at LENOVO can get me a part number for a new board and I have wasted over a month trying.

Who can help me!!

Welcome To Lenovo Community


We are really sorry to hear about the issue you are facing,  

Please try disconnecting all cable from the unit , Now press the power button for 30-40 sec then release , perform this action 4 -5 times , now connect AC adaptor  to check  by powering on and booting the system. If system is working fine,


In case issue remains same please contact local Lenovo support to have system verified





Do give this a try and let us know  




Hope This Helps
