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.

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
Does anyone know if it is safe to keep the charger cord attached while changing the battery? The goal, of course, is to prevent a hard reset. (Obviously, all data should be backed up to SD card first.)
Is there a post somewhere that outlines the recommended steps for the battery change? (Search has not yielded one.)
Thanks,

Hi, I recently replaced my battery with a higher capacity battery bought off ebay for $22US del from HK to UK in 5 days. search for ezipda, later bought one for an Ipaq for same price.
The process of changing over took 5 mins, BUT!! I would not recommend having it plugged in and changing batt. You may be shocked by the result (pun intended). I cant remember if it did a hard reset but dont think it did. As long as your back-up battery is charged and u are quick dont think there should be a problem.
Unscrew the screws and get a wide thin blade and go around the edge of the case, I didnt and caused a few marks ont he edges! There are a number of clips that pop open quite easily. The battery is held in place by double sided tape, use the the same blade and carefully prise the battery up. Replacement is a reverse of the procedure, the only tricky bit is the connector is quite small and a bit difficult to locate but not too bad.
Hope I have helped. :lol:
Thanks, BadgerBoy1.
The backup battery is the key, but how does one determine if it is working and charged? I've searched all over the system for an indicator of the backup battery, to no avail.
That begs the next question: If the backup battery is bad, where is it, and can it be replaced?
There is a little switch on the right hand side of the battery, just above this little red strap with "pull" on it. What is it for?
If you remove the battery cover while the unit is on I suspect you'll find out.
dooh
Put a new battery in (2600) and then tried a new ROM.
For the last month I've thought that it was the ROM that caused my Tilt to turn off whenever I slid it open to use the keyboard....
So (not troubleshooting first ) I returned to my original AT&T ROM and SPL figuring if it was still happening, it must be hardware, so I'd return it.
Did all the above, it was still happening. So on a whim I dug out my old original battery, and loh and behold, the problem ceased.
Anyone else have any issues with a new, bigger battery and battery cover causing their Tilt to turn off when you slide the top?
okay, for anyone who is remotely interested, I figured out what was going on:
whenever I slid the top too quickly, the phone would turn off...so I figured it must be something loose with the battery.
I added just a small piece of cotton from a cotton ball between the battery and the cover and snapped the cover back in place.
Now I am assured that the batter does not have any room inside the case to move at all.
can anyone tell me what the 2 gold contacts under the battery cover near the top right of the phone are for?
