Black Screen After Boot up

My T420s (2 months old) recently has been giving me a black screen after boot up (no "Thinkpad" image is displayed during boot up).  System totally unresponsive -- I have to push on/off button multiple times.  Subsequent boot up usually OK.  Sometimes once I'm up and running, upon entering sleep mode, the machine will not wake up.


I have adjusted power management setting and and up-to-date on all drives.  HELP!!!

Re: Black Screen After Boot up

if this is constantly occurring this would mean something is wrong with the Thinkpad's hardware, since this laptop is fairly new, you should consider getting it fixed under warranty.
