Laptop CPU swap blackscreen

[TheSouthernBear]

I own a Gateway NV55S03u and it started to be slow. I noticed that it could do an upgrade to the CPU. So, I got an A8-3500m to replace the old A4 3300m. It all went fine and then I went to start it. It turned on but I got no video. No BIOS. Nothing. Just black. Before I did the swap, I did a BIOS update to the latest one. I tried to reset CMOS. Nothing worked. When it comes to compatibility, Gateway and Acer both used this motherboard with the A8. So good chances mine would too. All I need is some ideas.

There is nothing you can do unless you happened to have bent a pin of messed up a connector during the change and can fix that. If the CPU won't boot the system on the latest BIOS, it won't work in that system.

Okay then. I'll put the old one back in and see if it is the CPU or a connector. Then hope for the best.
