Warning! Your Xda II can be hard reset after change battery
I experience hard reset after change battery twice, and also our member of www.pdamobiz.com were complain about Xda II can be hard reset so easy. Even change battery in 1-2 mins. So upset!
Fininally I can find the root cause, that's battery cover in the back.
So, today I take the photos to show that is the real cause. Anyone would like to try, don't forget to backup.
......
Any time that you want to change battery, of course you have to open the battery cover in the back. Then after take out the battery, just put the cover on the back. See picture:
Aha! do you know, the cover is metal, and electricity can passthrough it as same as electric wire. Battery backup of Xda II is also only like Big Capacitor, it's pole are still connect to the contacts.
If unfortunatly, the cover move down forward to the contact as picture.
See at Red Circle. Battery backup will discharge through the metal cover immediately. You just know nothing but after insert new battery you will find new screnn as:
Hard Reset!
So, if you don't want to be as this, do not put the cover or anything that conduct electricity over the back of XdaII while no batterty.

So this is only likely to happen if you short out the contacts 'cause you don't put a battery in when you close the lid!
To be honest that's not something I'd do anyway. Interesting, but not really suprising that this could happen. I guess that you, in effect, short out the internal battery.

like the rest of the xda casing the backpanel is not metal but
painted plastic
and even if it were metal then it would be alu which is a pretty lausy conductor

I didn't believe it but he is correct - I just tried it out myself!
The paint used on the plastic does actually conduct electricity (I know it's a different device but hold an XDAI while charging and then lightly touch a second charging unit and you'll get a slight shock!!)
Still it's probably not a problem for most people because most people only remove the battery to change the SIM card or replace the battery and as such wouldn't ever touch the connectors with the case!

It is not painting, it is a metallic film, it is possibly chromium.

hi all ,
the reason why your XDA is loosing all data when you put the battery cover back without the battery is because the cover pushes the red switch !!!
this is the backup battery switch so you are pushing it to off position ! so there will be no power to support the ROM .
XDA is designed in way that when you want to remove your battery you have to unlock the red switch which is the backup battery switch so you will turn it on to support the ROM.
when you take your battery you are not supposed to turn the switch off before you put the main battery back,so when you are placing the back cover there is no way to fit it in place if the switch in the on position so it is pushing on it back to the off position leaving the ROM without power.
Regards.

Hard reset when changing battery... there is more to it
Hi all!
I have read with a lot of interest all the couses you described for hard reset while changing battery, but there must be some more.
When I change batter I pay attention to:
1) the lid
2) the red switch position
They are fine, but still the machine hard reset... I believe the problem might be due to the fact that sometimes after a battery change the XDA does not feel the new battery after I switch the red switch back so it doesn't turn on I loose all the memory... any idea on how to avoid it or be sure that the XDA has good contact with the battery before switching the red and crossing fingers...

had a hard reset too
I had a battery-change hard reset too recently.
I'm 99% sure I didn't screw up on the lid or the red switch.
Scarry. I lost two weeks of stuff that wasn't fully backed up.
I change batteries on a regular basis...

Scarry is a lot of people don't bother to make a backup...
I could care less about a hard reset, i just restore my backup from SD-card and sync.

Jpiek,
for me hard reset is still a pain becouse afterwards due to a change in the datestamp the PPC duplicates or deletes contacts in the PPC... so I need to manage the post-back-up sinc and that takes around one hour... are your backups more convenient? What software do you use?
Thanks,
Chris

I just backup useing the standard Xbackup, then re-sync with my up-to-date Outlook on my PC...
Works just fine for me...

Is anything new about this problem of Hardreset?

Hi all :
Just a little question, ammar :
If actually the red switch connects the backup battery, what happens when the standard battery is gone ? How do the backup battery gets active if we don't act the red switch ??
Thanks

XDA II Won't turn on

I've just got back from work having lef my XDA II on O2 at home, and the thing won't turn on!
When I plut it into the charger, a faint red light comes on (where the green signal indicator usually is), However after a few minutes charging it should deffinitely turn on, yet it still does not.
Does anyone have a clue whats going on??
If the main battery and backup battery run out, shouldnt sticking it in the cradle charge it?
Any help much appreciated

Try removing the main battery for a while then try again.

I've had a few of such experience. It won't turn on. Even charging it from the power main, soft reset, take out main battery for a minute or half...
The only way to wake it up is to HARD RESET.
Strangely, I thought somehow the battery ran dry, but after one hard reset I noticed the main battery was at normal level, backup battery 100%. How frustrating. It happened a few times already.

8) I also found this problem. I use Spritebackup and schedule to backup everday at midnight. So, I can restore after have to do hard reset

What ROM version are you running on your XDA2?
I had the same problem on my MDAII and I was on 1.60.00WWE but an upgrade to 1.72.00WWE fixed the problem. That ROM also used to wipe my SD Memory!... Now I'm on 2.06.00WWE (Windows Mobile SE) and it's better than ever!!!
Good Luck!

I had the problems when I was on 1.60.00WWE. Since the very last hard reset (device not responsive to soft reset after a flight in February), I changed it to Sin's Merged ROM version 2 (WM2003SE). I wouldn't say it's better than ever, as I noticed the device is slower but it has been ok ...

I just joined the list because of this issue.
I have ROM Ver 1.72.00WWE and Radio Version 1.17.00.
I only upgraded both ROM and Radio in the past fortnight. It's only since the upgrade that I've had the problem of not being able to 'wake' the XDA and having to do a 'ahrd' reset. I have also another issue regarding the GPRS connection but I'll write a separate email on that.

XDA II Problems
Its nice to know other people have the same problems.....
I have had similar problems and either just remove the battery or do a soft reboot. As I travel a lot, I can't get to my desktop to back up. So I use a 1GIG SD card. But I have'nt lost any data yet.
One annoying problem I had was the damn thing kept switching on every time I picked it up or put in the hard case, or even just laid it down. It seems to have disappeared now. Has anyone else had the same problem? :roll:

so its fate!
check in this morning and mine is doing nothing, nada, zip
hmm soft reset nothing check the threads and this ones at the top!
used all day yesterday sitting on the charger overnight and bingo its dead...

Same problem
Have had intermittent problems with being able to turn on. Took battery out for a while and when it decides to work it automatically has performed a hard reset. Use daily for receiving jobs, recording serial numbers using BT scanner and then e-mailing. As well as being my phone and GPS. Have started taking my laptop with me just so I can restore data on the run.
What a pain!

XDA Problems
From the replies given it appears that the problem lie swith the battery. Has anyone raised this with the supplier? I was thinking of getting a spare one, but they are a bit pricey.

I honestly don't think it's the battery that's at fault. This is because I didn't have any problem with my XDA II until I upgraded the ROM and Radio recently. Secondly, it happens irrespective of whether the battery is fully charged, half charged ... whatever. IMHO, it's whatever was done in the upgrade!

When I got mine back from repair the battery was totally drained as well as the back up battery. would do nada, not switch on, nothing whatever I did.
A few minutes on the charger was not enough. You have to leave it in for about 14 hours once it's in that state for it to become live again.
Don't ask me why, but it needed at least 14hrs on that mains charger !

I too suffer this problem .... only since upgrading too.
Will try the Spritebackup method

guys i have a similar problem. my power button has broken and i turn on the device with the record button (i have remapped the buttons). Yesterday i turnd it on and the screen freezed on the today screen . I performed a soft reset, the screen went blank and it never turned on. Now the device is dead, soft reset won't work, it doesn't seem to charge (no light when i put it on the cradle) and i cannot perform a hard reset because i do not have a working power on/off button.
Is there anything i can do to turn it on?

Before the experts arrive, you could try removing your battery and simcard and leaving them out for a good 15 minutes they try again.
I broke the power on button off my last xda, my hubby soldered it back on

I've had the same problem since 10 days now. First time (friday), the phone just reset itself (hard reset) without reason... 4 times within 2 hours. When I came home i reloaded it for 12 hours and restored a backup. It worked fine from saterday until wednesday.
Then on wednesday it reset (hard reset) itself almost 10 times. Thats the first time i noticed a red light when I tried to recharge. The red light dissapeared after a couple of minutes and the phone would switch on again ... in hard reset mode. Again I left it charging a whole night and restored the backup the next morning. It worked fine again until ... yesterday (monday)... I dropped it (stupid me). It went completely dead. Even when recharging for 2 hours the light was still red. A new fully charged battery (my first thought) did not help a bit.
This morning I opened it up (its about 18 months old, so no more waranty) and i found nothing. When i closed it up... it did a hard reset !!! I changed nothing inside (I even found a little piece of metal afterworths that must have fallen out!). I suspect it was the fact that i removed the battery AND the SIM-card for more than 30min that did the trick. My phone is not SIM-locked (illegal in Belgium to sell sim-locked phones, good thing, but they are a lot more expensive here too). A brand new battery did not help.
Problem is ... when I send it in for repairs, it will be gone for about 4 weeks ! And the best they can do is give me a Sony Ericsson P900. I appreciate their effort, but carkit wont work, no GPS, etc... so i would rather try to solve the problem myself. I'll contact the repair center today and see what they suggest. I'll keep you posted

Cissen, how did you get on? Have you found an answer to your problem yet?
Edit: Mine crashed again yesterday and it showed the battery as being empty although I had fully charged it the day before.... so, I have now ordered a new battery.
They are pretty pricey for branded ones but I found this site yesterday so have ordered one from there - only 20 pounds including delivery so not wasted too much if they're crap
http://britishpound.ecyan.com/batteries-chargers/batteries---mobile-phones-and-pda---o2.shtml

I've got this problem too, when I first got it, it turned for about three seconds then turned off, so I thought it was a dead battery. but when I put the battery in there is no charging light, I have tried 2 different batteries that work fine in my other xda IIi. If I take the battery out and place in the charger a red light comes on.

Ei guys. this is a bit different from your experience. Anyone experienced by just changing battery it went hard reset? or just by changing sim card on the phone, removing the battery just for a second the phone went hard reset although I did checked the backup battery which is in 100%. Anyone?

have you checked that your backup battery, the one built into the phone is fully charged before you take out the battery. (check in your settings menu under power)
i have replaced mine from a totaly broken xda (picked it up on ebay) as mine had failed and would no longer hold a charge for more than a few seconds.
i also had major probs with a hi powered battery it kept failing for some reason, totaly losing charge in a mater of hours on standby and this kept hard resetting my phone. so i no longer use the larger batteries.

The backup battery is fully charged
After have taking off the main battery about five minutes and putting on a fully charged one the back up battery might shows the power percentages about 25%.But It almost takes me about 30 seconds to change a another new battery,it's not possible the backup power's problem. I change battery exactly the same way when I do it.That's just too weird it sometimes hard reset and sometimes just doesn't.

The backup battery is fully charged even after having take off the main battery for three minutes!so there is nothing to do with the backup power.
I change battery exactly the same way everytime.Why just sometimes it gets hard restted and sometimes it doesn't.It makes me wonder.
Is this eda ii a broken one?Maybe I should turn it back to the repaireman's house for a few weeks?you know how bad China's services are ,they never do things that customers need.

Thanks your heartkinded help anyway

Thanks the same way though your idea seems not where the problem at.

like i mentioned it could just be because one of your batteries has an intermitant fail, as i said i had the same problem with a hi capacity battery, it somtime hard reset my phone for no reason.
just try buying a couple of new batteries, or lable your batteries and see if its only on one of them that the HR occurs.

My 8125 resets itself

There have been many occasions where the phone would go into hibernate, then wouldn't come back on when i hit the button. So i would remove the battery, turn it back on and put in my passcode, but it would reset itself to the original factory date. What ,if anything, can i do to fix this problem?

Nothing. The time and date is powered by the battery, and if that either dies or is removed, the date and time reset to factory defaults.

You are right ashasaur!!!
The last time I saw a backup battery, was on a HP iPAQ jejejej the backup battery keeps the clock and date... but now.... I think your problem is the resets and no wakes up! so.... this must be a battery problem maybe is almost dead... try to buy a new one...

well this has happened twice today, I've seen on the net in other places that a rom update may also help this concern. Any ideas where I might start? Also when I checked the battery after the last time it read 82 % so I figured I was good, I took some contact cleaner and cleaned the battery contact points and the battery itself. I'll see later..
Thanks for the quick responses, I had thought there may have been a small watch type battery inside so thanks for clearing up that idea as well.
As an addendum to this the phone is now stuck on the cingular opening and it wont do anything unless I pull the battery and start allover, even when the wall charger is attached with the battery I can only get the charge indicator once. This stinks....

backup battery status still says 0%

I've even tried putting the phone on the cradle without the main battery to see if this would force a backup battery charge. The charging light stays red, and after a couple of hours, backup battery status still says 0% (so it's not a sensor issue), and if you remove main battery, it continues to be the same as a hardware reset.
On a positive note, xbackup seems to restore things quite well.
Can anyone else think of any good ideals?
The error message on boot-up emphasizes the problem
"To prevent possible data loss, replace or recharge your battery according to the owner's manual"
I find no such instructions in my owner's manual.
i have also purchased a new battery but still don know how to charge backup battrey

Could be the backup battery is dead my friend. You can google for the service manual to take the XDA apart. The battery is basically a large watch battery so a replacement should be quite cheap.
I had to replace the touch screen on mine, I wont lie taking the XDA apart is a bit of a pain. You will need a very very small screw driver and a torque (6 i think) screw driver.
Hope this helps

I had the impression that backup batteries stop'd working period when one went from ppc2003
