On the the IPAQ 6515 and others, there is a USB Power option that you must enable to 'slow' or 'fast' charge from USB connection.

Hard reset and charging problems


do the hard reset again .. hold the power button down while operating the reset in the back .. keep the power button down for a few seconds .. that should bring up a display "delete all" .. you can choose to do so .. that will be a hard reset .. now if the battery is dead and the charger is not working then nothing will work for you .. you might have a bad charger .. often the end that plugs into the unit develops a broken wire inside the cable ..
the m515 wont charge from the sync cable (shame) it needs the external power adapter .. make sure the connections on the charger and palm are clean .. the power adapter is 5 volts and i think about 1 amp .. )(center pos) if you want to try another adapter .. the tip is rather standard ... also you can get a universal power adapter from radio shack that will work on just about anything .. you just plug in a suitable tip .. the tip for your palm is an "A19" .. the power adapter is "IGO" wall adapter 23-1401 model PSM08VADJ ... that seems to work nicely and it plugs directly in to the palm .. so you can work with it plugged in .. when the charger is working there should be a lightning bolt thru the battery symbol .. it sounds like you already know that .. if the battery has gone open then it may not indicate a charge .. but the unit should still work while on the charger if that is actually working ....

Ipaq H3835 PDA - won't hold charge??


If you purchase a new battery, they usually come with directions and special tools to change the battery. I had the same issue with 2 of mine when I got them at a used electronics store. IF it is the battery that is not working, then replacing it is easy, and you can get a replacement at your local Battery-Plus store.

In my case, one was fixed by a new battery, the other was not, and I actually had to press pretty hard in the cradle to get the second one to work. It never worked out of the cradle, so I gave that one to a neighbor kid to tear apart and see if he could get it working. (I got them for $15, so no big loss.)

Does not turn on


There are some known issues with the included charging equipment. Personally, I ordered a relatively inexpensive charger from Amazon.com that works wonderfully. All you really need is a device that turns a standard wall plug into a USB charger. You can then plug your base that the ipaq stands on into that and it should begin charging. The old battery is probably dead (mine was), but try to charge it anyway.

Note: The actual cord that came with my charger DID NOT WORK. It is sitting in a box somewhere, and if its the same thing I had (it probably is), then you just need the wall-to-USB converter.


This is what I bought:

It is only $10. Again, the cord didnt work for me. Maybe it will for you, but if you manage to find just that converter for less money, more power to you!

I got the same problem. I even tried to plug the battery to the second battery charging slot, still couldn't get it back to life. But the Ipaq screen lights on with progress bar progress for about 5 seconds, then dead again. I even doubted the battery was toasted.
I gave it a final shot:
1. Remove the battery, and then put it back.
2. While the screen lights on, within 2 seconds, cold reset the unit by press the hole with stylus and push the power button at top in the same time.
In my case, the progress bar will keep going until I see the tap screen instruction and everything back to normal. But it reminds me that the removable battery is totally discharged. So I put it in cradle and I am able to synch it with my PC. Everything seems o.k. while it sits in the cradle, except the charging light won't turn red.
When I remove it from the cradle, it still lights on, battery shows 99% which is healthy. but when I turned it off, it won't start anymore. I have to repeat the above steps to revive it. Sometimes I have to remove the battery and wait for a while and then put it back, so that the screen can light on to give me chance to cold reset.
Conclusion: Maybe need a new battery. I will check Ebay to get one.
Please post if you have other solutions.

I had a similar experience. My device would not charge via the usb charger so I connected it to my wall charger and it charged successfully.

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.
