• If you have a PCMCIA I/O card-that is, a card having an external connection, such as a modem or network card-remove it when you're not using it. Some I/O cards use significant power, even while they're inactive. To recharge the battery or run on ac power • Plug the power cord into the adapter, then into a grounded ac outlet. • Insert the adapter plug into the socket on the left side of the OmniBook. AC adapter CAUTION Power cord Charging light Use only an HPF1044B ac adapter (the type shipped with the HPOmniBook5000). Using any other adapter could damage the OmniBook and void your warranty. Always plug it into a grounded outlet. Note that the adapter plug has negative polarity-the inner contact is negative, and the outer is positive. You use the ac adapter to recharge the battery pack in the OmniBook. You can also use it to avoid draining the battery-so it will be at full capacity when you're away from your desk. (You can even use the ac adapter while the battery is removed.) It's a good idea to use the ac adapter during operations that take more power-for example, those involving external connections, such as using a floppy drive or serial port. You can also use the ac adapter if you don't want the OmniBook to turn off unexpectedly-when it's plugged in, the OmniBook won't turn off automatically. The charging light turns on while the ac adapter is plugged in. It shows the charging status. • Orange: Battery is less than 90% charged, ac adapter is connected. • Green: Battery is more than 90% charged, ac adapter is connected. OmniBook Operating and Recharging Times Description Typical Time Operating time, from 100% charge Nickel-metal-hydride Up to 2 1/2 hours maximum* Lithium-ion Recharging times, from 0% charge: Nickel-metal-hydride Lithium-ion Up to 3 1/2 hours maximum* Up to 3 hours Up to 4 hours * Actual time depends on the particular OmniBook model, type of battery, and actual usage-see "To save battery power". 14
