英文方法有更多种，但是根据机器的不同有些方法是大家没有的
Found this on PDA Avenue, and thought it would be beneficial to post here as well:
1.Soft Reset
A soft reset tells your handheld to stop what it's doing and start over again. All records and entries stored in your
handheld are retained with a soft reset. After a soft reset, the Welcome screen appears, followed by the General Preferences
screen.
Use the reset tip tool (see below), or the tip of an unfolded paper clip (or similar object without a sharp tip), to gently
press the reset button inside the hole on the back panel of your handheld.
Reset Tip Tool: On most PalmOS handhelds, the stylus that comes with your handheld has a reset tip inside. To use it, unscrew
the barrel from the stylus quill.
2.Double-Soft Reset
If your device doesn't seem to want to power up after a soft reset, and you've checked the other obvious solutions (fresh
batteries, power button, contrast wheel, contrast button) you may want to try the 'Double-Soft Reset'. Simply perform a soft
reset as directed above, but press the reset button twice in quick succession.
3.Warm Reset
A warm reset bypasses any system extensions (such as HackMaster hacks, OS patches, Alarm settings, etc) that are loaded on
your handheld. Sometimes a damaged third-party application will try to respond to a reset but will fail and cause the
handheld to 'hang'. Using a warm reset, you can start the handheld, then delete the damaged application before it has a
chance to try to run again. After deleting the application, follow with a soft reset to start up the handheld normally.
To perform a warm reset:
Press and hold the upper half of the scroll button on your handheld.
Using the reset tip tool (or a similar object without a sharp tip), gently press the reset button inside the hole on the back
panel of your handheld.
When the Palm Computing Platform logo appears on the screen, release the scroll button.
If you're not sure which application is damaged, you can use a tool like ResetEmu in conjunction with a warm reset to help
pinpoint the offending application.
4.Hard reset:
A Hard reset deletes all applications and databases in RAM. It then recreates the default (empty) standard databases
belonging to the applications in ROM. The PDA is left as it was when you bought it.
How to perform a Hard Reset:
1.Hold down the power power button on the front panel of your handheld.
2.While holding down the power button, use the reset tip of your stylus or an unfolded paperclip, to gently press and release
the reset button.
3. Wait for the Palm logo to appear and release the power button.
4. When a message appears warning that you are about to erase all data stored on your handheld, press the upper scroll button
(or whatever the corresponding equivelant is) to complete the hard reset.
You should be able to restore everything by doing a Hotsync. So do this first.
5.Extended Hard Reset
An Extended Hard Reset will completely erase your handheld, and will also bypass the creation of some default databases.
This differs from a normal hard reset, which will automatically create the databases for the built-in applications, and will
insert some specimen records into those databases: numbers for Accessories and Technical Support will be created in your
Address database, a registration reminder will be created in your ToDo database, and several helpful memos will be created in
your Memo database.
In addition, a normal hard reset will also create a Network database with some default Network profiles for your Network
panel in Prefs, and a file of several default MIDI alarm sounds will be created.
If you have the Notepad application, a normal hard reset ensures a sample note will appear on your NotePad, and if you have
the Mail application, an email message from 'Mail Help' will be automatically inserted in your handheld Inbox.
An Extended Hard Reset will ensure that all of these startup files are not created.
If you decide to perform an Extended Hard Reset and install one or more third-party applications that expect to see the
built-in databases present, you may encounter an error. For this reason, it's suggested that after an Extended Hard Reset,
you run each of the built-in applications (Datebook, Address, ToDo, Memo, and if installed, NotePad and Mail) at least once
to ensure empty built-in databases are created.
After an Extended Hard Reset, you will not be able to select alternate alarm sounds for Datebook alarms, but the default
alarm sound will still be heard for appointments with alarms set.
To perform an Extended Hard Reset:
Hold down the power button on the front panel of the handheld.
While holding down the power button, use the reset tip tool (or similar object without a sharp tip), to gently press the
reset button inside the hole on the back panel of your handheld.
Release the reset button.
When the logo screen appears on the screen, release the power button.
When the message appears on the handheld screen warning that you are about to erase all the data stored on your handheld,
press and hold the upper half of the scroll button on the front panel of the handheld.
While still holding down the scroll button, press, in any order, the Datebook button, the Address button, the ToDo button,
and the Note/Memo button.
Release the scroll button, to to complete the hard reset and display the Digitizer screen.
Pressing some but not all the buttons while holding the scroll key will result in a normal soft reset. Pressing no buttons
while holding the scroll key will result in a normal hard reset.
6.FlashPro Reset
On machines that have FlashPro (a third-party enhancement that provides user-access to free Flash memory) it is possible that
moving a corrupted application into Flash will prevent the unit from responding to any of the three normal resets.
The makers of FlashPro have provided for an additional reset procedure that will reformat your Flash memory.
Never perform a FlashPro reset unless a hard reset does not solve your problem.
To do a FlashPro reset:
Hold down the memo/note button on the front panel of the handheld.
While holding down the memo/note button, use the reset tip tool (or similar object without a sharp tip), to gently press the
reset button inside the hole on the back panel of your handheld.
Release the reset button.
When the logo screen appears on the screen, release the memo/note button.
When the 'FlashPro' message 'Hit the ToDo button to reformat flash' appears on the handheld, press the ToDo button on the
front panel of the handheld to perform the reformat.
Applications and databases you stored in Flash will be removed, and you will need to reinstall them.
7.JackFlash Reset
On machines that have JackFlash (a third-party enhancement that provides user-access to free Flash memory) it is possible
that moving a corrupted application into Flash will prevent the unit from responding to any of the three normal resets.
The makers of JackFlash have provided for an additional reset procedure that will temporarily hide applications you have
moved into your Flash memory.
To do a JackFlash reset:
Use the reset tip tool (or similar object without a sharp tip), to gently press the reset button inside the hole on the back
panel of your handheld.
Release the reset button.
Immediately AFTER step 2, press and hold down the Memo button. If you do this correctly, the Alarm will sound.
Once the alarm sounds, release the Memo button. This should allow the Palm handheld to reset correctly, but the contents of
Flash will not be visible until you run JackFlash or perform a hard reset.
Run JackFlash and then move the items that were placed into Flash back into RAM.
This procedure does not remove any data from Flash; it hides the contents of Flash from the handheld. You can still use
JackFlash to access any valuable data.
8.Debug Reset
Sometimes while upgrading the Palm OS, there will be a connection interruption or other problem that will render your Palm
completely unusable, due to an incomplete operating system.
The debug reset will open up your serial port to allow an OS install utility to write a replacement OS directly to Flash.
A debug reset should be done when OS upgrade instructions call for it.
To do a debug reset:
Press and hold the lower half of the scroll button on your handheld.
Using the reset tip tool (or a similar object without a sharp tip), gently press the reset button inside the hole on the back
panel of your handheld.
When the Palm Computing Platform logo appears on the screen, release the scroll button
9.Battery Disconnect Reset
Treo 600 only
A battery disconnect reset is a last resort step you can take to cut battery power, wipe all data, and regress a Treo 600 to
its factory-fresh state. It only works on a Treo 600 smartphone.
To perform a battery disconnect reset:
1. Disconnect your Treo 600 from the AC charger.
2. Hold down the K and Backspace keys simultaneously. (Note: for French AZERTY keyboard, press K and M; for other language
overlays, please refer to the customer support for your region)
3. While continuing to hold down the K and Backspace keys, press the RESET button inside the hole on the back panel of
your device (where's the reset hole?).
4. Finding it hard to do? Good. We made this type of reset very awkward to perform, so that it would not happen by
accident when your Treo 600 is jostling around in a pocket or bag. Sorry for the inconvenience. You might want to ask a
friend to lend a hand if you find it too difficult to do by yourself.
5. Continue holding down K and Backspace. The screen will flash white briefly, and then go black. Release K and Backspace
after this happens. Your Treo will appear to be "dead" and the screen will not turn on. If you see any activity — such as
the screen turning back on — the reset was performed incorrectly; try again
6. To revive your Treo 600, connect it to the AC charger and plug the charger into a socket. The screen will stay blank
for several seconds (as long as half a minute), then it will turn on. The LED will glow solid red, indicating charging.
7. Finally, follow the steps for recovering after a hard reset (a battery disconnect reset is an extended type of hard
reset).
10.Zero Out Reset
Zero Out Reset
Tungsten T5; Treo 650 only
A zero out reset will regress a device that has non-volatile memory to its factory-fresh state. When done correctly, it
completely rewrites your device's internal memory with zeros and ones, ensuring that any data is expunged. It should be used
only if you want all information completely obliterated (example: you're selling your handheld, or you're sending it in for
repair, and want to protect your privacy).
Tungsten E2 note: a hard reset (above) produces the same results as a zero out reset - completely rewrites data on internal
memory. No need to perform the steps below.
Warning: A zero out reset will erase everything on your device. All your data will be removed, and formats, preferences and
other settings are restored to their factory default settings. Don't perform a zero out reset unless you want to eradicate
everyting.
HotSync note: If you wish to continue using your handheld after a zero out reset, please be aware that some third-party
applications change the way your handheld backs up data. Other third-party applications do not back up data. If you have
third-party software on your device, please contact the developer to learn what components are backed up during a HotSync
operation, and if HotSync conduits are altered. Any data not backed up will be permanently deleted.
There are two ways to perform a zero out reset.
