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

I don't recall ever seeing a typical clear glass fuse that wasn't
permanently marked with numbers pressed into the end cap.

Some old pigtails were often fitted with pressed-on "over" caps (to which
the leads were resistance welded), and removing the caps would reveal the
numbers in the underlying cap on the glass.
Flush-cutting wire cutters, or even a utility knife will cut the pressed-on
cap, it's only plated brass.

If the numbers are covered with solder, wick off the solder to reveal the
numbers.

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.

City of Industry, CA 91745-1712
Tel: 626-336-6878
Fax: 626-336-5657

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.
