Align the replacement t6 power battery with the battery bay and press until it clicks into place, then secure any latches. Reconnect the AC adapter and charge the new battery fully before first use to calibrate charge reporting.

Usošanas ieteikumi

For optimal battery life, avoid deep discharges and store the battery at around 40–60% charge if not used for extended periods. Use the original charger or a compatible HP adapter and keep laptop firmware and power management drivers up to date.
