Question about HP iPAQ HX2490 Pocket PC
I have just stumbled across your site, whilst searching for assistance regarding my current problem with a new ipaq 210 (Enterprise 214 here in the uk).
Please can you help...
The ipaq won't now start from the mains - it will only start using the internal battery, and seems to work normally then. I use a mains charger, that is clearly charging the ipaq ok, as I have tested it going from from 98% to a full charge (orange light turns green on the ipaq). So the cable is fine. It must be something to do with the ipaq itself.
Note that I only recently tested the alarm clock (turning the ipaq on automatically). But I haven't done anything substantial with the ipaq, just tested videos, used an sd card, synched with my PC a few times, and installed calligrapher (I have been mostly writing notes to get it used to my handwriting). Occasionally I stop all programs to clear the memory.
Can you advise initially? - then I can fill you in on anything you might want to know.
I have found a few forum chats about this starting problem issue - one respondent suggested he do a hard reset, but isn't that a bit extreme? However, I may have to try it (if you don't have an easier solution).
Worst HP site on earth, but welcome!
never post email on any forum that be bad bad news.
why do that, erase that, want 1billion SPAM in one day
wow. that is scary, no?
your A/C walls mains,power pack is no good
it runs on battery
in most cased. only real tests, tell real truth'
but you have no meters, or know how to dismantile

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.

If you are not using the original chargers it could be the type of charging cable. Not all cables that fit will charge the device correctly.

I have to agree with DirtyHarry1, it sounds like the battery could be weak. On my iPAQ when the battery is done charging the charging light changes from orange to green, I'm not sure if yours will do that. I'd try leaving it charging on the cradle for about 24 hours to see if that improves the life any.

It's a problem with either the memory board or the button board. With my h5550, the bottom buttons started to stop working and eventualy the PPC stoped charging all together. You can find parts for it online. If all the buttons are working fine, then it's most likely the motherboard. Otherwise it should be the button board.

I had some similar experiences with these ipaq's when I was working in a specialised service center. I'll try to give some help or tips through the internet, altrough if i could have seen or diagnosticate these pda's myself it would have been more easier. First of all these problems have 2 main causes. Most of the pda's comply with one of them, it is very rare that a pda will develop this problem by having both causes.
The first cause is the hardware one. A component called the main voltage convertor is broken. It's a small chip that uses the voltage given by the main battery to convert it's value to various tensions required by some of the components on the pda's main board. If some sub-parts of this chip fails to work, the result will appear as the problem you face, In this case there isn't much to do. Most service centers will replace the whole mainboard because that particular chip is very hard to find as a replacement and difficult to desolder from the board.
The second cause could be a major firmware / ROM memory corruption. These things can happen out from nowhere. In my time working for service centers I've tried to isolate a pattern for this problem but without much succes. However it seems that most of these problem tend to appear durring charging cicles due to power spikes or drops on the main AC voltage supplied to the charger. This is only a supposition, I'm not sure yet on this cause. What to do here? Well this problems are fixable but first of all you must be sure that this is a software problem, not a hardware one. So let's diagnosticate some things.
Try to charge the pda. Ignore any lights or beeps or whatever your pda is showing on the screen. As long as the charger is connected the charging process is based on the most primary charging circuits on the pda's motherboard. If the pda is not charging or cannot hold any charge (when you unplug it the screen fades away or it simply doesn't do anything else) maybe that circuit is broken (this is a a sign of serious hardware problems ) or maybe the battery is to old/weak. Batteries don't die out of nowhere, if you remember your pda to work and have some 2-3 hours of standby time it's imposible that now, suddently the battery has drained out so much that even if charged it can't hold out at least 30 min.
So we will assume that you charged the pda for at least 2-3 hours and you see some sign that the battery is working. The next step is crucial. TRY TO PUT THE PDA IN BOOTLOADER MODE. You will achieve this by pressing (and keep them pressed!) the following buttons : power, the far left and right buttons near the control pad (joystick or whatever some people call it) and reset button. You may need another person to help you press these buttons. the order should be the following (first power, then the 2 keys, then reset button for as long as it takes to enter bootloader mode). YOU SHOULD SEE A WHITE SCREEN WITH THE HP LOGO.
If your pda fails to do that, there is nothing more you can do to restore it in a DIY fashion. Probably the bootloader is corrupted or you have a hardware fault. Only a specialised HP service center can help you now. In most cases this will end up with a motherboard replacement.
If your pda does that, then there is a chance to fix it. We will need to probe the bootloader for direct data acces. This is needed for having the ROM memory (and operating system) rewritten. A small program called Mtty will be required to access the bootloader via an usb link.
Please make this tests first and then reply with your results. If anyone of you is in situation #2 there may be a chance.
