Question about Palm Z22 Handheld
Every time I try to access the "memo" screen, my Palm goes blank and gets stuck until I do a soft re-set. What's going on? Should I try a hard re-set?
I believe that this problem relates to the BlackScreenOFDeath or BSoD - which is caused by a low or weak battery allowing the CONTROL Logic circuits to get into an invalid state where the ON/OFF/SLEEP/CHARGE/ FUNCTION transistors are niether on nor off. I would recommend getting a new battery as soon as possible. Doing a SOFT RESET "may" get you temporarily going again. DO NOT do a HARD RESET !. I have posted many discussions on the Z22 that you may find helpful, on my tiny website,
One other possibility, is to take apart the Z22, and wipe the buttons and traces with a soft damp cloth to remove oils, water, and possible spilt liquids from the touch/snap/button/discs areas. Even the tiniest trace of conductive liquids will short out the logic circuits, causing "unknown: states on the control circuits.
My answer on the BLack ScreenofDeath, is as follows:
The Z22 suffers from 3 problems. One of these is the Black Screen of *****. 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 *****. 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 :
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! )...

I would do a hard reset...but after you are sure have backed up your data, as it will wipe back to factory settings....
