LITHIUM ION BATTERY

Lithium ion Battery

Your Lithium ion battery is durable and long lasting but should not be exposed to extreme temperatures, high voltages, chemicals or other hazards.

Warm Swapping

Your C Series notebook comes equipped with a bridge battery. A bridge battery allows a charged Lithium ion battery to be exchanged for a discharged one by "warm-swapping".

To warm-swap, have a charged battery ready to install, put your notebook in Suspend mode, remove the low battery and quickly insert the charged battery. The bridge battery capacity is not large, and can vary with the condition of your notebook, so you will have 3 minutes at the most to make the change.

Batteries can, of course, also be "cold-swapped", i.e. with the notebook powered off and the AC adapter disconnected. In this case there is no time limit.
