Problem Diagnosis/Remedy 
HP Jornada automatically 
shuts down/suspends. Power is too low to run the Pocket PC. 
When a critically low power condition is 
encountered, the HP Jornada initiates a 
safety shutdown. Connect to AC power and 
charge the battery.  
–or– 
Auto-suspend activated. To conserve 
power, the HP Jornada auto-suspends if it is 
idle for 1 minute immediately after power is 
turned on. It also auto-suspends if it is 
continuously idle for 3 minutes. 
–or– 
HP Jornada is locked up. Connect to 
external power, and reset your HP Jornada. 
(See the Resetting your HP Jornada 
section in this chapter.) (Caution: You may 
lose any unsaved data when resetting.)

running applications, or it 
runs slowly. HP Jornada is locked up. Connect to AC 
power, and reset. (See the Resetting your 
HP Jornada section in this chapter.) Note: 
Check to ensure that the device is not 
running low on power, and avoid running 
several applications at the same time. Use 
HP task switcher to close applications that 
are not in use.

Problem Diagnosis/Remedy 
HP Jornada does not turn 
on or display appears to be 
off, even though power is 
on. HP Jornada has run out of power. Charge 
the device by connecting to AC power
 
Backup file created with the 
HP backup application on 
another HP handheld device 
cannot be restored to the 
HP Jornada. Only PIM data can be migrated to HP 
Jornada 540 Series Pocket PCs. 
Because 
the HP Jornada 540 Series Pocket PC uses 
a newer operating system, it is 
recommended that you restore PIM data 
from an older device by using Microsoft 
ActiveSync or Microsoft Outlook rather than 
HP backup. Synchronize your older HP 
handheld device with Microsoft Outlook on 
your desktop PC, and then establish a new 
partnership to transfer data to your new HP 
Jornada. 
Difficult to install or run 
software from previous HP 
handheld on HP Jornada 
540 Series. Software that runs on previous HP handheld 
devices may not run on your HP Jornada 
540 Series Pocket PC.
 Because the HP 
Jornada 540 Series Pocket PC uses a 
newer operating system, software built for 
previous generation Windows CE for Palm-
sized PCs (such as HP Jornada 430/420) 
may not run on your HP Jornada 540 
Series. Check with the software vendor for 
an upgrade or newer version that will run on 
the HP Jornada 540 Series. 
Inaccurate response to 
stylus tap. The calibration of the touch screen may be 
off. 
Realign the touch screen by pressing 
and holding the On/Off button to open the 
Align Screen control panel. 
Can’t find or replace main or 
backup battery. The HP Jornada 540 Series is designed with 
an integral high-performance rechargeable  
Li-ion battery for operation and data 
retention. You need only connect to external 
power to charge the battery for 
uninterrupted usage and data retention.

Remote connections 
This section offers troubleshooting help for connecting your HP Jornada to 
other computers. For problems communicating with your desktop PC, see 
ActiveSync Help. 
Able to dial out, but unable to make proper 
connection 
Make sure the network to which you are trying to connect supports Point-to-
Point Protocol (PPP). Your Internet service provider or network administrator 
can verify this. 
Verify that the dialing location is correct. On the Start menu, tap Settings, and 
then tap Connections, Modem, Dialing to ensure the Location field reflects 
your current location. 
Modem connection is unreliable 
Make sure the modem is firmly seated and connected to your device and the 
telephone jack. 
Disable Call waiting. On the Start menu, tap Settings, and then tap the 
Connections tab. Tap the Modem icon, and then on the Dialing tab, select 
the Disable call waiting check box and enter the disable code specified by 
your telephone company. 
Unable to use infrared transfer between 
Windows-powered devices 
If you are unable to use infrared to transfer information between Windows-
powered devices, try the following: 
• Transfer only one file, or no more than 25 contact cards, at a time. 
• Position the infrared ports so that they line up and are less than 20 cm 
(8 inches) but more than 5 cm (2 inches) apart. 
• Make sure nothing is between the two infrared ports.  
• Adjust the room lighting. Some types of light interfere with infrared 
communication. Try moving to a different location or turning off some 
lights.

Network connection problems 
The following solutions may help if you encounter problems when using a 
network card for network connections. Additional troubleshooting information 
is available in Connections Help on the device and ActiveSync Help on the 
desktop PC. 
• Verify that your NIC is compatible with the HP Jornada 540 Series Pocket 
PC. 
• Verify that you have added necessary server information. On the Start 
menu, tap Settings. On the Connections tab, tap Network. Tap your 
installed adapter (usually your Ethernet cards name) and enter any 
necessary information. Most networks use DHCP, so you should not have 
to change these settings unless your network administrator instructs you 
to do so. 
• If Network Connection isnt listed as a connection method in the 
ActiveSync dialog box when starting synchronization, wait a few minutes 
and try again. Also, if synchronization does not start right away, the 
network is probably busy, and it may take a minute for your device to 
connect to the network. 
• Make sure that the proper drivers for your card are installed on the device. 
For more information, see the owner’s manual for the network card. 
• Verify with your network administrator that your user name and password 
are correct. 
• Verify with your network administrator that the network you are trying to 
connect to is available, or try to connect to it from another computer.  
• You may need to change the device name if you are trying to connect to a 
network and cannot because another device with the same name is 
already connected. To change the device name, on the Start menu, tap 
Settings. On the System tab, tap About, and then the Device ID tab. 
Cable and cradle connection problems 
The following solutions may help if you encounter problems when connecting 
to your desktop PC. Additional troubleshooting information is available in 
Connections Help on your HP Jornada and ActiveSync Help on your desktop 
PC. 
• Ensure the device is turned on. 
• If a modem or Ethernet card is inserted into your device, remove it. 
• Ensure that you do not have any other active connections. On the Start 
menu, tap Today. Tap 
 or  at the bottom of the screen and then 
tap Disconnect.  
						

							102 | HP Jornada 540 Series User’s Guide     
 
• Ensure the cable is securely plugged into the COM port or USB port on 
the back of your desktop PC. Use the cable that came with the device 
without any extra cables or extenders attached. 
• Plug the other end of the cable securely into the correct port on your 
device. If you are using a cradle, push your device securely into the 
cradle. 
Display problems 
If you are having trouble viewing data on your HP Jornada screen, follow 
these suggestions. 
Screen is blank 
Follow these steps if the screen remains dark or if the device does not 
respond when you briefly press the On/Off button: 
• Press the Notification button/LED to ensure that the display is on. 
• Adjust the display contrast and brightness. On some devices, the screen 
can be darkened or lightened until the device appears to be powered off. 
(Refer to Adjusting settings section in chapter 5). 
• Reset the device. After a reset, the screen remains blank for 
approximately 3 seconds after pressing On/Off buttons. 
• Charge the device by connecting to AC power. 
Screen is dark 
Prolonged exposure to direct sunlight may cause your device screen to 
temporarily darken. This is normal for LCD screens and is not permanent. 
Display is difficult to see in sunlight or in dark rooms 
Use HP settings to adjust contrast and brightness for optimal viewing. (Refer 
to the Adjusting settings section in chapter 5). In very bright light, select the 
Outdoor profile in HP settings. In very dark conditions, select the Low Power 
profile. In a dark room, you may also need to ensure that the backlight is on 
and/or position a lamp so that the light shines directly on the screen. 
Screen is hard to read 
If you are having a hard time viewing a document in Notes, try changing the 
size of the view. To do this, tap a zoom percentage on the Tools menu. In 
Pocket Word and Pocket Excel, on the View menu, tap Zoom and then select 
a zoom percentage. In Pocket Internet Explorer, on the View menu, tap Text 
Size and then select a size.
