Well now it ends up in my hands. I tried the clock battery removal no luck. It shows a it shows the IBM splash screen then goes to a lock with the number 1 next to it and I think that means its a supervisor password. Could just be a HDD not sure. But I do know thinks to the security chip I'm locked out. Any help would be appreciated.

I replaced it and the CPU with a brand new Pentium M CPU. I hit the power button, fan on cpu spins briefly then stops, hard drive spins, dvd/cd drive boots, and power on indicator turns on. Nothing shows up on screen and it just sits there with the hard drive running. Any idea?
