Alright, here's what I'm gonna do.

1) Connect the power supply to the new, non-working 14.1/292.

2) Remove the 32 MB RAM card from my current, working 13.3/250.

3) Install this RAM card in the new PB and power it on.

If it boots, in goes the 128 MB RAM card, hard drive, battery, and CD-ROM.

If it doesn't boot, out comes the 32 MB RAM card, processor, and display to be installed in my working 13.3/250.

Good?
