Re: 5550 not powering on
Was the battery a exact replacement to the one you removed?
also do you have the power adaptor for it put the old battery back in and see if it will run off the adaptor with the old battery plugged in and then you know the issue is with the new battery and not the unit itself.

I Also Had The Same Problem. Now I Fixed It. Go To Power In Settings. Click On The Advanced Tab. Uncheck The Box Which Says "Turn Off The Device If Not Used For" Box. This Will Solve The Problem. It Solved Mine. Thereafter Once, My Backlight Did Not Switch On. Fix This By Going Into Backlight Settings And Uncheck The Box Which Says "Turn Off The Backlight If Not Used For" Box. This Will Solve It. Then Soft Reset The Device To Change Settings. To Soft Reset, Find A Small Hole In The Left Hand Side Of The Device. Put Your Stylus In And PRESS ONLY ONCE. If You Keep It Pressed, Your Device Will Hard Reset. Don't Do That. Just Press ONCE.
Performing a Full Reset
A full reset is sometimes referred to as a ?hard reset.? Perform a full reset when you want to clear all settings, programs, and data from RAM.
A full reset deactivates the battery. The power button does not function until the battery is reactivated.
CAUTION: If you perform a full reset, your iPAQ Pocket PC returns to its default settings and loses all information that is not recorded
To perform a full reset:
1. Press and hold Application Buttons 1 (Calendar) and 4 (iTask) on the front of the unit and, at the same time, use the stylus to press the Reset button on the bottom of your iPAQ Pocket PC.
2. Hold all buttons until the displayed

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.
1. In the interest of not costing you extra money, wait a few days to see if anyone has any last-ditch ideas.
2. Your battery is probably completely dead. Try purchasing a new one (Amazon.com is good).
DO NOT THROW AWAY THE OLD BATTERY!!! If the new battery still does not work, the old one has probably been shorted by the charger, but it might not have been, and you will now have two working batteries.
3. If that doesn't work, then like I said, you probably have a short in your charger. Refer to
For the solution.
You can try these solutions in either order, but this is the order i suggest.
When you charge up your iPaq, do you use the cradle, or do you use the AC-adapter with the little iPaq power converter that came with the iPaq?
Try both, and see if it charges up your pda.
Try and borrow an iPaq car-charger and see if it charges up that way (the ones that do not need the iPaq power converter).
If you are lucky enough to power up the iPaq even for 2 minutes, enable USB fast charging in the SETTING -> BATTERY. Your USB-data-cable or cradle will then be able to charge it up that way...
