Yoga C930 Zoom on Camera lost after Update

I have a new Yoga C930.  The camera doesn’t seem to work – I can select it on the apps menu, and the function opens OK but the camera is dark (black, nothing there).  Am I missing something?  How do I turn this on?  Is the camera maybe not installed?

W510 cannot power on after replacing thermal paste, loud "chirping" sounds coming from 135W adapter

Hi all,


As my W510 was already experiencing thermal issues prior to this, so I stepped in to replace the thermal paste with the thermal Grizzly Kryonaut on the Graphics Adapter and the CPU. I applied a thin layer although it was slightly uneven, then replaced the components.


When I tried re-booting, the computer got stuck at the bios screen and I powered it off.


It now refuses to power up, and I hear a rather loud chirping sound coming from the attached 135W adapter, as if the adapter is powering on and off repeatedly.


I have reseated the RAM and reset the CMOS but to no avail.


Have I created a short circuit somewhere? Is my unit really dead?


I would appreciate any assistance here. Thanks!
