HP Probook 4545s Richland support

[Licentia]

Hi, I have a Probook 4545s and two A10-5750M processors that won't work in the laptop even with the latest bios, F.68.  The laptop seems to run but nothing is displayed on the screen with it installed.  However, it runs fine with the A10-4600M.  Does any one have or can anyone make a bios modification to enable Richland support for this model?

Have you a hardware programmer?

I have a Willem programmer, but no parallel port on my laptop or desktop computer.

You need cheap CH341A & SOIC8 test clip. Try to find it on ebay or aliexpress

Come back when you can read BIOS chip by it.
