system unable to wakeup from sleep after new BIOS firmware

HP Recommended
elitebook 745 g2
Microsoft Windows 7 (64-bit)

Hi Team

 

After new BIOS update 1.44 ( latest) >> my Win 7 is unable to wakeup from sleep. 

When I try wakeup with power button, notebook  seems waking up ( according FAN noise ), but display is still black....

 

Before I got probably BIOS v. = < 1.10   ( this was my first FW update after 2 years  of this notebook)

 

I tried  also downgrade BIOS back to older version, but  then I am facing with another issue, that all BIOS older then 1.44 is getting  below error >>  BIOS image did not pass validation,..

only latest BIOS is working.

 

I tried also update AMD graphic driver to latest version, but not solved "sleep/wakeup "issue.

 

Do you have any idea please ?

 

Thank you
