Automatic Brightness Issue

Does the ambient light sensor on the hx4700 only adjust a certain small percentage depending on light conditions. Mine only adjusts a very small amount up or down. Is this normal?

Re: Automatic Brightness Issue

The automatic brightness feature is useless to me because of two reasons. First, it is too dark to start with. Second, it does not respond as fast as I like to see. I end up using only two default settings- Battery or AC mode.

Mytouch 3g slide screen doesnt light up


I have the same model but 4g. I often notice the same problem, but once i step out of the full sun/bright lights, i notice that it is infact dimly lit. This can be adjusted by opening settings > display > brightness > turn off automatic brightness and set the level to at least %50.

now, if your screen is literally too dim to see, try this : Press the power button quickly, now unlock the screen by sliding your finger from the bottom center up to the top center and releasing, all in one fluid motion. This is the default screen-lock gesture and the brightness, if this is indeed the issue, should go up one notch upon unlock. From there, follow the above procedure to turn up the brightness.

hope that helps

Hp ipaq hx4700 hp invent is on but unit will not power up


I had the same problem which showed the exact screen you're describing and was able to sort it by downloading the ROM update from the HP site - they show it only available for US but works fine on UK machines as well. It takes a short while to install but has restored mine back to normal again. (only problem was incompatability with windows vista - works fine with XP)

Sidkeick 3 backlight


Have you tried checking the Battery and Display settings from the main screen Settings menu? There is an option to enable or disable the backlight, as well as set the brightness.

There is also a setting called "Use ambient light sensor", which sets the backlight and keyboard light to only turn on if it is dark when you are using it.

Just disable the settings where it says to turn off the backlight & PDA power after certain minutes and set your standby time (in power battery setting) to 0, then leave your PDA on until it fully drains (usually a week or two).

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.

Date & Time of calendar


Sounds like your PC is not set to adjust for daylight savings.... the ipaq automatically adjusts for daylight savings but the PC does not. On your PC double click on clock, click on Time Zone tab and then on that screen you will see the box that needs to be checked. also check that both PC and IPAQ are set to same time-zones.

Series Back Light


It is possible that by holding the power button down too long, that you turned off the backlight. When you hold down the power button, a menu eventually comes up with "Backlight Off" highlighted. The easiest way to undo this, is to simply do a soft reset. Or, you can hold down the power button again, and "Backlight On" will be highlighted (if there's enough ambient light you can see this message); just tap it, and the backlight will come on again. Also check out your backlight settings by tapping: [Start][Settings]tab[System][Backlight] the tab [Battery Power] should be highlighted; adjust as desired. Next tap the tab [External Power]; adjust as desired. Finally, tap the tab [Brightness] and make sure the sliders are high enough.
