Power Battery types: Removable 14.4-Vdc rechargeable NiMH (same as OmniBook 4000) and new Lithium Ion battery [LiIon (OmniBook 5000 only)]. Both battery types do not require complete discharge before recharging. There is no "memory" effect that reduces battery life. Battery Life; rundown data (approx.): Note: The LiIon battery will not work on the OmniBook 4000 -- the recharging circuitry will not accept it. The LiIon battery is double-keyed and will not plug in to the OB4000. Recharge time: NiMh: 2 hr 45 min LiIon: 4 hrs Note: If unit has 1 LiIon and 1 NiMh: 4 hrs + 2 Hr 45 min = 6 hrs 45 min. If unit has 2 LiIon: 4 hrs + 4 hrs = 8 hrs.
User can utilize any combo of LiIon and NiMh batteries in the OB5000. Low battery signals: 2-minute low battery warning. Unit will shut down if battery warning ignored to ensure data retention. Instant on: Maintains OmniBook in ready-to-work state for 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 5000 utilizes the same technology as the OmniBook 600 to achieve the instant on feature. Smart Battery: The OmniBook 5000 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 OmniBook 5000 no longer has to rely on software to determine the condition of the battery. The condition can be checked using two methods that receive information from the BIOS (CONFIGURATION [fn][f2], Windows Control Panel Power).
