The Z22 suffers from 3 problems. One of these is the Black Screen of Death. I got a used Z22, and over the years discovered this problem. The small battery was a perfect fit of power and size when manufactured, decades ago, but, time alone has deteriorated the capacity, so that a "NEW" , sealed-in-the-box Z22 today, has a weak, dying battery that needs replacing. These are $10 free shipping from China. The BSoD seems to be caused by a dip in power from the battery to the LOGIC CIRCUITS that control the ON/OFF/SLEEP/CHARGE, etc states of the Z22. If the logic gets out of sync, the unit is in an INVALID state, will not charge, nor respond to the LOGIC buttons on the front - these buttons are NOT the standard ON/OFF buttons from the past that mechanically connected or diss-connected power. All the buttons on the Z22 are touch snap disks that are connected to transistors, to flip logic states. THUS, is the power in any of the transistors gets low, the transistor is neither ON nor OFF, and the control circuits are in a messed-up state. Or another way of looking at it, the ON button is a logic gate on a transistor network, and the only way to activate the "ON" logic state, is with full power to the circuits! -- the power on the Z22 is ALWAYS ON. . . The screen may turn off, and the chips may go into "sleep" mode, but the Z22 is always on. SO if there as a weak battery, you may get the random Black Screen of Death. The GOOD news, is the the DATA and programs that you purchased are incredibly SAFE, as long as you do NOT do the HARD RESET (which someone suggested ! (NOT ) ). I have ripped apart the Z22 dozens of times, and subjected it to freezing and heating and all sorts of horrible things, the data has always been 100% reliable, -- stored in permanent memory. There is a quick way to get rid of the BSoD - you have to open the unit and cut one of the two battery wires, wait 2 minutes to kill the logic circuit power, then re-connect. I added a switch on the Z22, just for this purpose. I would recommend, if you get the Z22 re-powered, to get a new battery as soon as possible. This should clear the BSoD for a while. See my tiny website :

http://kidbots.com/WEBADD/Z22_PALM_PILOT/Z22_PALM_PILOT.htm

There are many photographs and step by step procedures to try to get the data off the device, maintain the Z22, get parts, and use the Z22 with the new 64 Bit Windows computers. The BEST way to use the Z22 would be to get an old Widows 32 bit laptop (ie WinXP), and simply connect the Z22 in a standard way using the software that it was designed for... The new patches to 64 bit machines, are very limited, and many previous features do not work.

So the bottom line - all your data, information, and programs are safe. You simply have to reset the LOGIC CIRCUITS (this has nothing to do with the PALM Z22 SOFT and HARD Resets !) - it has to do with disconnecting the power from the battery, or waiting until the battery is COMPLETELY DEAD ! (which can take a long time! )...

Good luck

My Plam Zire 21 handheld has worked fine; suddenly it will not turn on, or at least the screen remains dark. I have tried re-charging the battery, and resetting the device, but to no avail. Any other...


It is possible that the battery has lost it's skill. If you can plug it in, either by usb to a computer or through the power supply, and the screen shows it is a goner.

The link below is for the palm zire m150 if your interested in replacing the battery yourself. The zire 21 is similar to that model so it's pretty much universal.

Is there a way I can revert my Palm Treo 650 back to original factory settings


Factory Reset for Treo 700p and 680 smartphones
If you've set a password on your smartphone, any hard reset will automatically become a Factory Reset. With this method, you'll enter a password and then perform a hard reset.
On your smartphone, launch the Security application.
2.If the Password box says "Unassigned," tap the box and create a password for your smartphone.
3.Once the password has been set, disconnect your smartphone from the AC charger and take off the battery cover. Do not remove the battery yet.
4.Hold down Power/End .
5.While holding down Power/End , remove the battery. Then insert it again.
6.While still holding Power/End , the screen will show the Palm logo and a progress bar. Then the circular Palm Powered logo will appear. Release the power button when you see the Palm Powered logo.
Keep holding the Power button during this screen. When you see this screen, you can release the Power button.
7.A message will appear warning that you are about to erase all the data stored on your smartphone. Press UP.
8.If you performed this reset correctly, the screen will go blank after several minutes, and you will not be able to turn on your device. The charging LED will not light up. (any other activity - such as the Palm OS logo and then the Applications launcher appearing - means the reset was performed incorrectly; try again) 9.Your device will appear "dead." To wake up your smartphone, perform a soft reset.

I have a Palm z22 that won't keep a charge. My


The Palm Z22 is, I have found out, a bullet-proof design in regards to reliably keeping your valuable "DATA" safe over time. The Engineers at PALM really did a good job of Data integrity compared to many other devices. HOWEVER -- there are 3 common problems with the growing AGE of the Z22, 2 are with the dying batteries, and 1 with the years of wear and tear on the touch screen. The battery is a typical square, thin, modern Lithium battery, wired in with two wires ( + positive, red, and - negative, black ) that can be
taken out and replaced if you take the unit apart. In a brand new, in-the-box package, the battery is dying simply from old age. If the Z22 was used heavily, the constant cycling from dead to fully charged wears out the battery even more. The Touchscreen is a thin layer of plastic stretched over a sheet of glass, with a tiny air gap in between. Over time, the top plastic layer deforms - with hot and cold, air pressure changes, and being pressed by wearing the unit in a pocket, purse, briefcase, or even in a drawer with pencils, pens, and staplers etc. It is very important to have a hard cover over the screen! Other than just having the battery loose its weak charge continually, there is a problem with the unit getting into a state of BLACK SCREEN - it does not charge and remains "apparently" dead, since the logic circuits are in an invalid state, and it can only be reset if the battery dies COMPLETELY to remove the power on the logic circuits.
I have covered the topics of the battery problems, the data problems, the screen problems, and the disassembly, maintenance, and security, and how to get data off the unit, particularly to the new Windows Operating Systems that were developed AFTER the Z22 was no longer made. This is at
kidbots.com/WEBADD/Z22_PALM_PILOT/Z22_PALM_PILOT.html
I have ripped apart the Z22 repeatedly, and posted pictures of the various steps to service these units. There are links to aftermarket software to transfer data, and examples of how to USE the Z22, for valid purposes. This should be a one-stop source for any information or troublehooting the Z22, for those who have the Z22 and want to keep it operating!
good luck

My Palm Z22 won't turn on. If I do a hard reset


It absolutely won't, you don't have to worry. I've done it several times, and I know I was really nervous at first, but it's fine.

Screen went black


That is a low battery warning icon. Check first the DC adapter/charger output. It might be not working so the battery is drained. Then the player will not turn on. The player will still turn on even the battery is dead when plugged into an outlet.
