I have a Lenovo IdeaCentre K220 for a few years now. Several months ago, I was booting up the machine and accidently killed it during boot. Now, when I try to turn it on, nothing shows. I don't know what is wrong because I have tried different monitors, different cables, and an external graphics card! It still displays nothing. I've even reset the CMOS! But when I remove the RAM, it give's me the No RAM error code. Then, when I remove the CPU and have no RAM, it gives me nothing. It's very strange and even my Next Door Neighbor who is a Senior IT Architect didn't know what to do. He even did a 4 ft drop test and nothing came loose! So, can anyone help me here?
