Erosannin Report post Posted May 19, 2016 I recently changed the processor from an A8-4500M (Trinity) to an A10-5750M (Richland) and as per internet, it should perfectly work, The laptop turns on but the monitor (which is new) stays black and nothing moves. Some people say that I might need a Bios upgrade in it. I went on the HP website and they released a new bios March 1st 2016. I want your opinion on this as the processor outputs some heat which means that it's somehow working. Share this post Link to post Share on other sites
