Re: Charging

If it's completely dead USB probably can't do it at all. There's a voltage threshhold, and USB only puts out about half the voltage needed to get over it. USB usually won't manage when thenbattery's below 30%. Try connecting the iPaq directly to the AC adapter.

IPaq rx3115 working like PC not Pocket PC, need to plugin always


You need to purchase a new removable battery for your RX
The removable batts usually only last about a year (like cell phone batteries).
Although it is showing 100% charge, the battery is not storing enough power to run the ipaq

The rx series uses 2 batteries, one is the removable one u can see/access when u remove the back cover. The other batt is a small round batt which stores the basic info for your system (so you don't lose your data when u swap out the removable battery).

This small (backup) batt is similar to the cmos battery on a laptop or pc.
You cannot easily replace this, as the unit needs to be disassembled to access this batt.
If you are tech-y (and brave), the replacement button batteries are sold on ebay for $9-12

Normally, if your removable batt is bad, you could still use your unit plugged in, and could
remove from AC power without losing data. Not the case if your replaceable batt is exhausted.
When both batteries are bad, you lose everything when u remove unit from AC power.

My workaround without having to disassemble unit:
Purchase and fully charge new removable batt (They have huge capacity ones available for like $15 - better than the original !).
Load up all your programs & settings the way you like.
Perform full backup to SD card (& also on PC via active sync - to be safe)
Now the only time you should lose your data (like hard reset) is if you allow the battery
to completely drain, in which case you can restore your backup.
If you purchase 2 removable batts, you can easily swapout without losing data if you
use the usb charge cable & leave ipaq plugged in while you change battery

Hope this helps

Main Battery Power


It cannot switched the batteries. The backup one is a small internal battery just to keep the CMOS with data. That's it.

If you main battery is not charging or when unplugged won't power on, the is likely the main battery is defective, or the charging circuitry of it is failing.

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.

Drained batteries, not powering up, next step?


For me I prefer charging the iPAQ using the usual cable, not the USB as I had some troubles with that It makes the battery drain faster. So Use a usual charging transformer.

My iPAQ will not charge or turn on ...


Can you get the iPaq hooked up directly to AC power? There's apparently a charging threshhold for badly depleted batteries that the USB port cannot get over.

Battery not charging on rx3115


Be sure the charger is connected to AC power. USB charging won't work when a battery's really dead. And it may take up to 24 hours, I've read, to get it recharged.
