DESPERATE for help!
My husband and I were working on a desktop HP a1210n, adding memory, and in order to do that we had to install a "critical" BIOS update 3.07-3.15 from HP website. We did that. It said everything was fine, installed beautifully, blah blah blah - restart and ... NOTHING. No post no boot. just the fan runs. We have tried pulling out and putting in battery power cord, etc. We are doing this for a client, and our reputation is obviously at stake here. Even called HP which we knew would be worthless, and was. Any ideas?
