What is the difference between hot boot and cold boot?

Q: Does the PDA have a "hot boot" and a "cold boot" like a desktop computer?

Answer: Warm Reset (Hot power on): usually you can see the "reset" on the back of the handheld computer, press the "reset" key once, the handheld computer is running hot boot. After hot boot, it is usually required to run the screen locator, so be sure to perform the screen locator before restarting.

Cold Reset: Press the Power on the key (please refer to the operating instructions) at the same time, then press the "reset" key, and then put off the "reset" key and then put off the power to open the key, the screen will appear system information, continuous point pressure power on the key, the system will run hardware tests, including LED, IrDA, Speaker, mic and so on. Typically this action also provides operating mode for OS upgrades. Please note that all previously entered data will be lost after the cold boot, so keep the backup data on the computer before running.
