No experience with this brand and model but I'm wondering if the new
batteries have more cells hence a higher mAH rating.  More cells means
either more current to charge them up (the built-in charger might not be
able to handle that high a load) or take longer to charge but result in
a too-low charging load (so the charger thinks the battery is dead and
will not attempt to charge for safety reasons).  New battery packs often
come delivered uncharged.  If the built-in charger cannot or won't
charge those new batteries then they come dead and stay dead.  Some
laptops will not boot if the battery pack is dead or removed even when
the A/C cord is connected.

According to what online specs that I could find on this brand and
model, it comes with a 6-cell battery pack.  Do the new battery packs
have 6 cells and are rated around 4400 mAH?  Or do they have more cells
and a higher mAH rating?  The built-in charger may not be able to handle
a 9-cell battery pack rated for 7800 mAH.

Doesn't look like anyone knew in the Toshiba forums where you asked at
http://www.forums.toshiba.com/t5/Batteries-and-Power/S70-B-Won-t-Power-up-with-Replacement-Battery/td-p/684795.
Did you try asking Toshiba support (http://support.toshiba.com/contact)?
