Question about HP iPAQ HX4700 Pocket PC

3 Answers

HX4700 will not power up

My HX4700 will not power up. It will also not charge when the unit is on the cradle. When I did a warm and cold reset it would come up to to HP screen but would go no further. I have 3 cradles and tried the machine in every one. The unit does not blink charge when it is put on the cradle nor will not power on. I bought a new battery and does the same thing. I have tried checking the battery clips to make sure they are tight. I have a separate charger for the bateries so I know the battery is fully charged. What could it be? Thanks

    I tried the following fix on my Ipaq HX4700 and it worked. Reflashing the rom woke up my dead ipaq. The computer will be able to sync the ipaq when it is put in flash mode. My Ipaq would not read or sync with my computer unless I put it into flash mode. The rom flash is a bit tricky and it took me several attempts to get it to work but it is fixed. Worth a try on a dead Ipaq. see below

    How to Recover your iPAQ after a botched ROM Update

    --------------------------------------------------------------------------------

    If a user is attempting to update the BIOS or FIRMWARE of their iPAQ and the power goes out, or they accidentally turn-off their iPAQ, when then attempt to restart the iPAQ, it will only get to a white-screen, where it then sits forever.
    Bboth soft and hard-resets do not appear to clear the trouble in most cases.

    Hopefully you will never need to use this step-by-step process.
    I have confirmed with Nathan at HP Technical Support that this is their approved recovery process:

    1.) Go to the Master Index of BIOS, FIRMWARE, & DRIVER Updates,
    2.) Select the appropriate hyperlink for your model.
    3.) Download the most recent BIOS version SoftPAQ (SP) for your Model of iPAQ.
    4.) Press the POWER + iTASK + CONTACTS + RESET buttons at the same time so as to enter the FLASH Mode
    5.) Make sure your USB connection to the Cradle is hooked-up.
    6.) Place your iPAQ in the USB Cradle.
    7.) Stop the MS ActiveSync session on your HOST PC: CTRL-ALT-DELETE > TASK MANAGER > PROCESSES.
    8.) Hilight WESCOMM.EXE and select "End Process" button.
    9.) Run the file you downloaded from HP in step 3.
    10.) The iPAQ should now begin Flashing the iPAQ's ROM BIOS.

    This should work for most every iPAQ model, however, we cannot guarantee this will succeed at restoring your iPAQ to a usable state.

I have repaired many of the Hx4700s that appear to be dead by shorting across the "battery locked" switch. It is located on the lower right corner of the board when viewed from the back with the cover off. The switch just shorts to ground when the battery is locked in place. By flowing a small bit of solder over the two connections on the back of the switch, the iPAQ will return to life and there is no ill effect of bypassing this switch. In my opinion the switch is to fragile and poorly placed.

Hi I'm a pc repair technician, and my ipaq hx4700 has gone exactly the same way. I've been looking round for some kind of technical manual to see if there is any history of internal components going down through heavy use or even manual abuse. Mine stopped after I knocked it whilst working on something. Normally if I see similar symptoms on a pc I'd be looking at internal component failure, more often than not the motherboard itself. I worked on that theory and have looked at prices for an ipaq motherboard. In all honesty the costs for the part and replacement are more than buying a new pda. Sorry for the bad news, but thats the only option I've found all the best

Hx4700 wont work after failed update on ROM v1.10


Try hard reset: pressing and holding the calendar and iTask buttons and doing a soft reset for 2 seconds.

Hard resetting a WM 5 HX 4700 is to press and hold the Contacts and Mail buttons and then doing a soft reset. The boot screen will popup with a message “To perform a clean reset, which will clear all data in memory, press the [Calendar] button”

If that fails, try upgrading to wm 6 or wm 6.1 then downgrading afterwards.

I've upgraded from wm2003SE to wm6.1 alkor rc2.2 rom.

Cannot power on...


How to correct iPAQ 5450, 5455, 5550, 5555 battery charging problems / dead unit syndrome.

The iPAQ 54xx or 55xx will not power on if the batteries charge is lower than 3.2 Volts, if your battery charge falls below the 3.2 volts level your unit will not turn on, you need to plug the iPAQ into a cradle or AC charge adaptor. Note the charging light on the iPAQ will not flash at all (normally flashes orange) until the battery charge has reached a minimum charge level of 3.2 volts. You then need to perform a normal reset, then the unit should switch on normally.

HP Procedure is as follows:

To charge and reset the iPAQ Pocket PC h5400:

i) Connect the iPAQ Pocket PC h5400 to an A/C power supply.
ii) Charge the battery to the minimum level of 3.2 Volts. This will take 5 to 30 minutes depending on the current charge level.
iii) Perform a normal reset.
iv) Power on the iPAQ Pocket PC h5400

It is recommended that you keep the iPAQ Pocket PC connected to the Universal Cradle or Cable when it is not in use.

Battery too cold


Was it stored in a place that has extreme temperatures? If so, some hardware might have become damaged. Try to let the battery warm up some and then try again. I would also try a hard reset if at all possible and if that still doesn't work probably call up HP and see about a repair.
