Make sure that your device supports the Wifi encryption you are using. As an example, the H4150 only supports 64 or 128 bit WEP encryption.

It should be possible to update the ROM to the english version.

You can download the update utility here:
The support site also contains installation instructions. Please be 100% sure that this is the correct update for your model before doing anything as an incorrect ROM flash can damage or permanently prevent your iPAQ from working.

Hi there,

I suggest to you to buy a new battery for you HP iPAQ H4150 Pocket PC and see if that charger will charge it up. If the new battery does charge then the problem was with the old battery.

If it doesn't charge up on the new battery then, your problem lies with the battery charger. You should check that the voltage of the battery charger is compatible to charge the voltage of the battery.

Hope I have been of assistance to you,

Cheers :)

You will need to ensure that the Wireless Security settings on your router are set to at least 802.11 b/g and not just 802.11g, as the h4150 is a 802.11b device.

There is also a ROM update to 1.10 and a WLAN driver update to 2.0.53A available from HP as well for this device. http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=349044&prodTypeId=215348&prodSeriesId=349042&swLang=8&taskId=135&swEnvOID=1087

Sound like you may be having issues with both battery and some apps running. Try a soft reset to see if it correct this issue.

Make sure you have the iPAQ connected to the AC power and in its cradle. With the stylus, press lightly the Reset button on the side of the iPAQ. This will reset your unit without deleting any apps. It will cause any app running to stop and shut down. Once reset, you should be able to use your unit without further issues.

Just in case, you can do a full reset which will put your iPAQ back to default state. This will delete any information that is not stored on the iPAQ base storage file.

Press the power button and reset button at the same time. Release the power button first, then the reset button.. This will reset the unit and power on. Post your results.

Good Luck

you might have a problem with you ROM image.

try downloading the rom image form hp.com and upload it (flash it) to your device using the RUU.exe file, activesync connection and a usb sync & charge cable.

Simple Solution:

Perform a hard reset and then attempt to login repeatedly (10x).

You will then be prompted if you wish to reset the pin entirely.

Good luck,
