Gateway urges customers to inspect their laptop battery to see if it checks out. If the pack is labeled by part numbers: 6500760 or 6500761 with "made by SMP" on underside of the battery pack, you've got yourself a potential live one. Stop using the battery immediately and contact Gateway to receive a free replacement battery.
The biggest problem for the recalls, as always, is actually getting everyone that purchased a unit notified. Interesting that it took them four years to discover these units.
