Re: will not come on at all

I have the same problem. I think these devices have a fault where they can not power up if they are emptied all the way. I had the same thing happen during warranty period and I sent the device to servis. They said nothing was wrong, but now the same thing happened and I have tried everything to get it back to life and no success... I guess I would somehow have to charge the battery outside the iPAQ as it will not charge

Re: will not come on at all

After a hard reset you must do a soft reset to enable the battery.

Tmobile dash isn't turning on

  1. Verify that the OEM Charger and Battery are being used.
    • Only the AC charger, Car charger, or USB data cable that came with or was created for the device should be used; others can damage the device and/or battery.
  2. Is the device warm?
    • When using the device for prolonged periods of time, such as when you're talking on the phone, charging the battery or browsing the web, the device may become warm. In most cases, this condition is normal and therefore should not be interpreted as a problem with the device.The device has a protection feature that if the device becomes too warm (due to use of GPS while charging, BT while charging, using the device as a wireless modem, etc), the auto protection feature will be triggered and the charging process will be stopped. Once the device cools down, the device will then begin charging again.
  3. Check the USB Port on the device for any bent or misshapen PIN's.
    • If some are found, that is the most likely cause and this is considered physical damage not covered under the Warranty.
  4. Remove the battery and inspect the contacts.
    • Remove any debris/residue found on the device or battery contacts with a soft, dry cloth.
  5. Look closely at the battery contacts on the phone to see if they are bent out of shape.
    • If they are bent, the device will need to be exchanged.
  6. Try charging the device (try different power sources as well as chargers):
    • Plug in USB to device and PC; is the LED indicating that the device is charging?
      • Note: If the device isn't charging while connected via USB to a PC, go to Start>Settings>More>Power>Power Management and make sure that "When device is turned on, do not charge the device when connected to the PC" is set to OFF.
    • Plug in AC Charger to device and outlet; is the LED indicating that the device is charging?
      • LED indicators: Charging is indicated by a solid Amber light on the upper Left side of the face of the device.
        • Note: If the battery is completely dead, the light will be a solid RED for a few seconds while it is charging; once the device has enough power to turn on, the light will turn to Amber.
  7. Try another Power Source.
    • Try a different outlet to rule out that as the issue.
  8. Try another battery in the device.
    • If another battery doesn't work, perform a Hard Reset.
      • If the device powers up after Hard Reset, test the unit for a few days. If issue returns, device can be considered for an exchange.
      • If device shows charging with one (AC Charger or USB) and not the other, issue is with the accessory. Replace accessory.
      • If device will only power up when attached to charger (AC or USB) it is likely the battery needs to be replaced.
Device won't hold a Charge
The life of the battery between charging sessions will vary depending on which features of the unit are being used.
  1. Verify the you are using:
    • OEM AC Charger
    • OEM USB Data Cable
    • OEM Battery
  2. Fully charge the battery using the OEM AC Charger
    • USB and car chargers are trickle chargers meant to get the user through until they can get to their AC Charger.
  3. If the device is not lasting the advertised Talk time, with minimal use, try another OEM battery in the device.
  4. If the battery life still is not meeting the advertised Talk time (with minimal use), the device will need to be repair/replacement.
Device won't Power on
  1. Attempt to charge the device.
    • If the battery is dead, the device will need to charge for a few minutes and then should power on once this happens.
  2. Attempt to power the device on by pressing the Power Button for 3-5 seconds.
    • If the device doesn't power in, perform a Soft Reset using the stylus.
  3. If the device still doesn't power on, perform a Hard Reset.
  4. Try another battery.
  5. If the device still will not power on, it can then be considered for repair/replacement.
Handset Powers off

  1. Make sure that the device is actually powering off and not just going into hibernate mode by pressing the power button once.
    • If the screen comes back on, the device is not powering down.
  2. If possible, check the battery level by going to Start>Settings>More>Power>Power Management.
    • The charge should be no lower than 10%; if it is, charge the device and retest.
  3. Try another battery in the device.
    • If the device stays powered on with a different battery, the issue is with the accessory not the unit.
  4. If the device still powers off with another battery, Hard Reset the device and retest.
    • If the issue remains after the Hard Reset, the device it can then be considered for repair/replacement.

My phone won't start on!

Nokia sometimes has a glitch where if the battery is too low it will not start properly again. Let it charge for some time when turned off - a couple hours, so it has enough battery power then remove the battery for 5-10 minutes, put the battery back in and try start it. What this does is re-sets the phone so it can start again. Also if there are problems during use that solution usually fixes it as well. What is happening is due to a low battery it tries to resume where it left off and cannot load itself properly to do so. Letting it go completely dead with no battery for a few minutes lets it drop it's old info and reload it's info to work again.

I have an htc ozone, what is the proper way to charge it for maximum battery life? seems to drain out shortly after an all night full charge. Thanks.

I just got my Ozone a few days ago. What you should always do with an electronic device is charge it fully before turning it on. Then using it until it dies completely with no battery. Then fully charge it again for maximum battery life.

You can go to Start, Settings, More, Power, Power Management. Change the different things to make it save on power. Also a big help is Start, System tools, Task Manager and delete everything that is being used. That just turns it off in the background, it doesn't delete the program.

Does not turn on

There are some known issues with the included charging equipment. Personally, I ordered a relatively inexpensive charger from that works wonderfully. All you really need is a device that turns a standard wall plug into a USB charger. You can then plug your base that the ipaq stands on into that and it should begin charging. The old battery is probably dead (mine was), but try to charge it anyway.

Note: The actual cord that came with my charger DID NOT WORK. It is sitting in a box somewhere, and if its the same thing I had (it probably is), then you just need the wall-to-USB converter.

This is what I bought:

It is only $10. Again, the cord didnt work for me. Maybe it will for you, but if you manage to find just that converter for less money, more power to you!

T-mobile dash wont turn on

In my experience when getting a phone wet your only choice is to let it sit. It could take a few days or a month but soon or later they usually fire back up.

My hp rx1950 won't turn on after a while

There could be a piece of software running that is locking up the device. You might want to check for updates to your PDA and any software you have installed on it. If that doesn't work try doing a hard reset, which will erase everything, then reinstall one application per day to see if the problem pops up after one of the applications is installed. If that doesn't work, it could be hardware issue, if there is an extra storage device in it pull it out and see what it does. You will have to troubleshoot. Try different things and see what the result is, eventually you'll be able to narrow it down.
