Battery Life; rundown data (approx.): w Recharge time (Display off): 4hrs (Standard Li-Ion), 5hs (Lrge Li-Ion) w Recharge time (Display on): 5.3hrs (Standard Li-Ion), 6.7 hrs (Large Li-Ion) Note: If unit has 1 standard LiIon and 1 large LiIon: 4 hrs +5 hrs = 9 hrs. w Low battery signals: 2-minute low battery warning. Unit will shut down if battery warning ignored to ensure data retention. Power w Instant on: Maintains OmniBook in ready-to-work state for days or weeks on a full charge; when turned on it returns instantly to previous state. No waiting for restoring from disk. Accomplished by the use of self refreshed DRAM technology. Note:
The OmniBook 5500 utilizes the same technology as the OmniBook 5000 and 600 to achieve the instant on feature. w Smart Battery: The OmniBook 5500 uses "Smart" battery technology. The battery itself contains an ASIC (Application Specific Integrated Circuit) that is able to continuously test and track the status of the battery. The OmniBook BIOS can then receive high-quality information about the battery condition directly from the hardware and not interrupt the CPU. The condition can be checked using two methods that receive information from the BIOS (CONFIGURATION [fn][f2], Windows Control Panel Power). w Energy S.T.A.R. compliant w AC Adapter:
100 to 240 Vac adapter (50 to 60 Hz) input; 12 Vdc, 2.5 A output. Same adapter as the OB600 (F1044B). Use only an HP F1044B AC adapter (the type shipped with the OmniBook). Using any other adapter could damage the OmniBook and void the warranty. Always plug it into a grounded outlet. w Power management options: Advanced; Standard; Off; Custom. w The OmniBook 5500 includes a "fake" off mode while docked. This enables the user to turn off the OB5500 while docked and not loose any connectivity (such as to a network). Basically, this mode shuts down the display only and maintains all power to ports and the CPU.
w A fully charged NiMH battery in storage will loose 20% of its charge per month in storage. External battery charger w Designed for desktop use. Powered by the F1044B adapter w Charges two additional batteries w Size: 15.5 x 13.3 x 5.2 cm (estimated), no weight estimate at this date w HP part number: HP # F1338A HP # F1193A Standard LiIon battery pack HP # F1064 - same as OmniBook 600 and 5000 Automobile adapter 14 Battery Type Run Mode Suspend to RAM Large LiIon 3 - 5 hrs 14 days
