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

Hi, please try first by unplug charger and then remove battery, after about 10 minutes, insert battery again and plug it charger, only the battery charging indicator should light on, if the status of other indicators keeps in the same way, maybe the motherboard is faulty and needs to be replaced, in such case, don't worry about your data, it can be recovered since hard disk can be taken apart from your computer to be connected to another one to access your data.

all old laptops, 101. asked here 100s of times,1000s, and answered as much,in IN DEPTH,
the pc will run for eternity on AC power no battery main
you do know that right> so do that first.
the fan is working, that is a good sign. sign of power may be ok.

1: the screen never shows text, like it did for 10 years.?
2: take out that old bad shorted main battery , does it run on AC now?
yes, no. (yes do the HP long reset, posted 1million times at HP and here,....both here and hp real forums.
(battery out, ac pack out, push power on, for 10 -30 seconds)
there 1,000,001 times.

3: no text?,got text? yes/ no. (if yes, does BIOS work) f10 prompted for 10 long years, still on the screen yes, then.,...read this.
http://h10032.www1.hp.com/ctg/Manual/c00820092

no text means the screen back laps are burned out or the AC pack is bad (or 20 other reasons seen in the link below)
(this is the most cheap fix of all)
4: the coin cell, RTC CMOS , is it 10 years old too.?
this kills the BIOS dead, so will be all things dead if BIOS is chaos.
BIOS uses the RTC ram to save settings, so.........coin must be good, 2.9v and more ok. less bad.
5: i stop here and show a link.

no beeps, no caps lock key blink codes..... RTM?
the pc here can be as old as 2007
if yes, then it can have CCFL, backlamps that love to fail now or sooner.
see this.

I have had a CQ60 Compaq for a year and a half. last night, it shut itself off and will not turn back on. I have tried the obvious-unplugging cord, removing battery and plugging cord in... nothing works!...


old CQ60s. (had?) have,
staples has real techs? really?
no they are just guessing, for a fact , if they did not do tests.
then they are (guessing or ignorant hacks)
first off CQ60s have a full model number like CQ60-100
never post lacking that, and the OS name like XP, or all answers will wrong.

so big battery out.
new power pack added for $8 new.
power on, fan must blow air, if not blow, clean first.
never seen any 10 year old PC or laptop not be packed in lent
causing overheating so easy.
the fan is first, then make sure the CD eject works
the what is next, the dead coin cell RTC/CMOS battery inside all this old are BAD< how can it be good this old ,it cant (unserviced PCs')
then with that replace and at 2.9v to 3.3v. you see
screens work you see text now. from MR BIOS
MR BIOS always works if the CCFL are not dead.

ever heard of CCFL , they ended just after the great year 2010
and LED was born,
But CCFL black lamps all fail, this old.
all do. as do HDD, Coin cells and all those old huge batteries.
leave the battery out now, big one. until the PC works again.
then get the screens working (hit F10(ESC) to enter setup)BIOS.
seen that hit message for 10 years, right, sure.
the goal on all PCs it to get that HIT text. there.

lets do you a list.
  • big batteries out. NOW , keep those DOGS out !!!
  • AC pack out. (disconnect)
  • hold power button for 10 to 30sec. and release (HP hard reset this is HP magic test on every hp page.....!!!)
  • AC pack new back on PC. laptop
  • power on, fan must blow, if not say so... now. (stop and ask )
  • Power on fan is ok , screen is 100% black no text.
  • got beep codes? or Caps lock led blinking codes?
  • BIOS is dead, hammering the ESC or F10 key as it prompted you for 10 long years, but is BIOS dead now. (no HIT)
  • new coin cell is next per your manual , ask. called by HP the RTC coin cell, search RTC in the service manuals of all HP PC. (real time clock) and if dead BIOS GOES DEAD.
  • Next, the flash light trick if the fan works and no text we do the flash light test, OMG the back lamp is dead !!!
  • http://www.pcdied.com/monitors.html#flashlighttest
  • the blackscreens of ***** page.
  • http://www.pcdied.com/black-screen.html#Laptop
  • did i cover it all?, seems yes, but tell more get more answers.

If you have a desktop computer but listing it as a laptop with a problem you will get the wrong information back to repair the unit so you need to take this out and resubmit it as the proper unit before anyone can give you the correct information!

dont they all , eventually. all do a fact. but why ? so leave that old battery out, run on AC for ever if you wish and for SURE TESTING. they love to fail and overload the PC. so with AC good power pack no main battery does the power turn on? y/n does the fan run (above is yes) does the cd tray eject does the bios message show on the screen, it must "hit f10 to setup?" means BIOS page. does it, or is the screen back totally no text EVER. even hitting the F10 key or the key it told you to hit for 10 years. that is called fan running and not packed up. the black screen of *****. we have no idea what YOU can do, your skills your tools, ? how can any person know that. if not black screens of deathh then say so and say what you saw fully this time. http://pcdied.com/black-screen.html its a nx9020 (2004, 13 long hard years old.!!!) not 9020, the nx matters . big time top black screens fan ok are? COIN cell dead. CMOS RTC battery coin main battery shorted, nah its parked on shelf. CCFL lamps it PC are dead. as all are this old do the flash light trick yet, fan blowing.

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.

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
