This unit is RoHS compliant, meaning it is manufactured without hazardous substances.
Shut down the computer, re-seat the battery connector, and ensure it is fully clicked into the port.
Check that the AC adapter is functioning correctly; try testing the charger on another device or using a different power outlet.
Before beginning installation, ensure the laptop is completely powered down and disconnected from the AC adapter. Open the laptop chassis according to the service manual for the Dell 7280. Remove the existing battery by unscrewing the mounting hardware and gently disconnecting the cable. Place the Origin Storage V4940 into the slot, secure it, and reconnect the power ribbon carefully. To maximize the life of the new battery, avoid exposing the laptop to extreme temperatures and perform a full charge-discharge cycle once every few months to calibrate the sensor electronics.
