I researched if I could upgrade the apu in my laptop and found I could if the bios was updated to version f23. I had version f22. So I updated it and got an amd a10-5750m apu to replace my amd a8-4500m apu. I was assured it would be a compatible upgrade. Laptop won't boot, caps lock light continually flashes and I have a black screen. Tried putting in the original apu and same thing happens. I could use some help please, thank you
