HP Omnigo 100LX / 120LX hard reset
Press the RESET button on the bottom of the device. Remove the main and backup battery for five minutes or more.
Soft Reset: SHIFT+ON+PgDn
System Reset: Immediately after turning on the machine press and hold the 'C' key for a second.
You'll be asked to initialize the RAM. Press 'Y' to initiate a Hard Reset, which erases all data in RAM.
If you press 'N' instead the machine will try to do a normal restart.
Resetting Your Palmtop
If your palmtop fails to respond to keystrokes or otherwise behaves unusually, you should do a system reset (also called rebooting the computer). Do not remove the batteries.
Caution A system reset erases the contents of system RAM (but not the RAM disk). Therefore, any data not already saved will be lost.
You perform a system reset by pressing CTRL+ALT+DEL (that is holding down CTRL and ALT and then pressing DEL).
If a system reset doesn't work, as a last resort you can attempt a hard reset by simultaneously pressing CTRL + ON + UP arrow (the gold arrow).
You will be asked whether or not you want to initialize the RAM disk, which erases its contents. If you type y (for yes) and press ( ENTER ), a hard reset will occur and all data is lost; If you type n (for no) and press (ENTER), a system reset is attempted.
CAUTION A hard reset erases the contents of system RAM and the RAM disk. All data on drive C (the RAM disk) will be lost. Also, settings changed via the Setup Utility (for example, battery charging) will revert to their default states.
