以往随身电脑电池性能实在令人不敢恭维,待机时间短且在电量耗尽时无法保护内存中的数据。而 Jornada568区别于以往的随身电脑,首创采用可拆卸电池,使它可以像手机一样随时更换,并且单块电池的使用时间长达14个小时。为得到快速的运行速度和节约费用,随身电脑往往把程序和文件存在 RAM中,但这样又极易因掉电造成数据的丢失。为保护 RAM 中数据,Jornada 568特设了一个3伏的纽扣式备用电池,它的电量能维持一天。但备用电池仅用于保护数据,不能支持 Jornada 568工作。Jornada 568显示器采用3.5英寸16位彩色反射式 TFT LCD,240×320像素。
In the past portable computer battery performance is flattered, short standby time and can not protect the memory data when the battery is exhausted. The Jornada568 different from the previous portable computer, the first use of removable battery, so that it can be changed at any time like a cell phone, and the use of a single battery up to 14 hours. In order to get fast operating speed and cost savings, portable computers tend to store programs and files in RAM, but they can easily lose data due to power loss. To protect the data in the RAM, the Jornada 568 features a 3-volt coin-cell battery backup that lasts for one day. However, the backup battery is used only for data protection and does not support Jornada 568 operation. Jornada 568 monitor with 3.5-inch 16-bit color reflective TFT LCD, 240 × 320 pixels.
