Default Anybody have a schematic for the SMPS for this laptop?

Anybody have a schematic for this simple SMPS?

AC to DC Adapter for the IBM Thinkpad T22
16V 3.36A

On the unit itself is
Battery Technology, Inc.
IB-PS365
09000000106991

from that I found:
Battery Technology, Inc.
16500 East Gale Avenue
City of Industry, CA 91745-1712
Tel: 626-336-6878
Fax: 626-336-5657
http://www.batterytech.com

but, they don't answer their phone, nor does their website 'find' any
refrence to this model?!
the 800 number from their own website comes up disontinued.

Anybody have a schematic? Especially interested in the input section
= AC mains up to the rectifiers and fusing.
