Won't boot past red screen, battery replaced

I have 2 3850's that won't boot past the red screen. I replaced the battery and it is still stuck on that screen. I can't turn it off either. Both of these pda's had the batteries die. Any ideas at all on how to bring them back to life?

Re: won't boot past red screen, battery replaced

Hey, when you say red screen does this mean it says compaq on it? If it does then you need to do as follows:
Press the two lower buttons (one is defult set to Calendar shortcut, the other to iTask) and the power button simultaneously while soft reseting the ipaq. It should start up. If not contact me, as I might of got the buttons wrong, at
I hope it helps

It is stuck on low battery screen and charging light won't come on.

Hi imrydn!

You can try these steps:

1. Connect the reader to the AC Adapter (If available). If not, then connect the Reader via USB to the computer

2. Hit the reset button for 3 seconds at the bottom

3. The red steady light should come on, if not, try the reset again while the unit is connected

4. Allow the reader to charge for 40 Minutes (on PC make sure the computer does not go into sleep mode.

5. Disconnect the reader and see if operational.

My phine dosent get past the main screen

Try a HARD RESET. This will wipe everything clean and you will loose all the data. Start by removing and reinstaling the battery. Then hold the POWER(red) + HOME buttons down to turn the phone on. YOu should see a triangle with a ! in the middle. Then open the slider and enter ALT+L. Then press ALT+W. Hopefullly this will make the phone work. If not then try to flash the phone. If it did not work, then you have other problems

Have you tried a Master Reset?

Hold the red power (end call) button, take the battery out, replace the battery. You will be prompted if want to reset the phone with Up for yes, and Down for no. This is how to completely wipe the phone to the state it was when you first bought it. Please make sure to have any custom applications and data on the device (other then data that comes from outlook) backed up. When you resync it to outlook, your contacts, emails, calendar etc will come back.

If after a master reset, the phone does not power on, then you will need to get it replaced, as this is a definate sign that the mainboard inside the motherboard is bad.

Red LED light means a major problem at the charging of the battery.

You have several options to repair it:

1. Leave several hours the PDA with not battery and unplugged from the AC power adapter, then put the battery and leave charging it.

It's more likely that the red light will appears again, but leave plugged it. Sometimes will start charging and blinking with orange color after 30 minutes or so. After that, it will work normally.

2. Use other good working battery to test it.

3. If the above two steps fail, then there is a good chance that the mainboard has a problem, and needs to be fixed or replaced.

Have you tried the classic "hard boot"?

Do you have a WAN or LAN radio configuration?
Has the device worked for you in the past ... and no will not?

Until you answer my questions and I get back to you you might try pulling the battery out for 10 min or so... see if it reboots when you reinstall it
