Completely New ThinkPad T60 from 2006

It sat 17 Years sealed in the office. Unfortunately the both the CMOS battery and the main battery are completely dead.

Tried it with a fresh CMOS battery.

I checked the 65W charger. It has 20V. Tried a different charger. When pressing the button the voltage on the charger remains stable.

I tried it with ram and HDD disconnected. Sti the same result.

I tried to charge the battery over night. But being deep discharged for thatong it won't work for sure and it didn't.

Laptop usually do work without the battery on a charger.

It just doesn't power on :( I just can't imagine a machine like that being broken out of the box. It's such a shame a beautiful machine like this unused not working. Before I go out trying pointless things like buying a new battery I thought I might ask here.
