What do you think my chances are of using the electronics in the standard battery to control 6 cells (ie. turn it into an extended battery)? Alternatively, what are the chances that the electronics in a PA2441U (a standard pack for the Portege 300) are compatible with the charging electronics on the Libby? The connector is the same, the size is the same and both laptops are from the same era ... the only difference is the connector on the Portege is offset to the left (or right?) by about 1cm so the pack won't actually slide into the libby (but some dremel work or replacing the back of the Portege pack with the back of a dead Libby standard battery will fix that ;-). - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
