XDA II Hard Reset itself when I changed battery

OK Guys lets see what you can suggest over this one!
I am a heavy user of the XDAII and as such I have 2 batteries and have had no problems in swapping batteries before. Yesterday morning (just before going on holiday) I was charging my battery in the XDAII using the powerlead and adapter and once it had completely charged I swapped it, so I could charge the spare as well. After I swapped it it decided it would hard reset itself losing all my data, software etc :x meaning a delay in me leaving as I tried desperately to put all the software back on (priority was Sat Nav and Speed Camera detector :wink: ) as I didn't have a backup .
What happened? - I've swapped batteries many times before without a hard reset. I can only think of the following two reasons
1) I was pushing the power button as the device reset itself after putting the battery in - therefore causing the hard reset. (pretty sure I wasn't but can't be sure as I don't have CCTV :wink: )
2) There is some form of power spike/drop that casued the hard reset as I had just disconnected the power cable from the device before removing the old battery meaning the backup battery wasn't in circuit (I doubt this one)
Incidently it appears that the SD card that was in the device at the time has been wiped - don't know if this is a seperate issue or whether this is linked (either way I was glad it wasn't my Sat Nav map data).
Any one any clues?

It sounds like the little red switch to release the battery wasnt fully slid over, or the switch in it had failed, if you disconnect the battery without this slid over fully it will hard reset the device and you loose everything,
The switch swaps the power over to the backup battery temporarily whilst you change the main battery, if it doesnt switch for some reason you loose all your data in less than a second !!

That may well have been it - I'd love to prove it but I hope you understand my reluctance :wink:

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

big problem, after taking battery out, Jam resets

The battery says its 100%. But everytime i take the battery out for 5 sec and put it back in again and turn on the pda, it is as if it has resetted and the stuff comes as if im putting it on for the first time (ie. the tap the screen and application stuff installs come) and everything is wiped off.

Looks like your battery is dead. Go back to your supplier and have it replaced

You mean the backup battery is dead?

i have the same problem
and i chang the backup battery
and update jame
and it's same whin u remove battery for 5 sec the phone do a hard rest
how can i solve this
plz helppppp

On Himalaya this ocurs too, but ONLY when the Phone was on (ie not in flight mode) when you take out the battery.
Remedy: Put phone in flight mode before taking out battery!
Maybe that also works with the Magician

But, every time you open the cover for the main battery, you switch off the device! There is a switch. Putting it bach into your MDA, you switch it on. Just this way...

Exactly, you switch OFF the device when the Phone is ON.
The are three ways to switch something OFF:
1. Go into Flight mode: Switches off the Radio functionality (including the Phone)
2. Switch off the PDA: Use the power-button, Radio Functionality remains active
3. Take out battery: All off!
When you take out the battery, the Phone (ie the Radio) has to be OFF to avoid a hard-reset.
When you take out the battery when the Phone is OFF, you only get a soft-reset

With my previous Xda II, I have the same problem too. But I think it's the small switch that cause the hard reset. When removing the battery we have to slide down the switch. After taking up the battery don't ever try to slide up the switch with the battery not in the place. Only when the battery is in its place then you should slide down the switch to lock the battery.

I tried turning on the flight mode before taking out the battery.. but the magician still resets!..
Any other suggestions?

With the Jam/mini, you NEED to flick the soft red plastic "Battery lock" out of its slot on the right hand side, or you will run the risk of a hard reset. You don't pull it right off, just flick it away from its "Locked" position. Not sure why a proper switch could not have been built in on the left hand side.

The red rubber is not connected to any kind of circuit.. it is there jsut to keep the battery tight.. anyways i tried it.. and my mini still hard resets..
Thanks for the input tho.

i have the same problem too... hard reset everytime i take the battery out even only 5 secs. i did turn the flight mode on, then press the power button. its not help. still hard reset. do you think the backup battery is dead?? how to check this? because its always show 100%.. please help.

hi all... for who has the same problem like mine (take out batery then got hard reset instead of softreset), the solution is: SENT IT BACK FOR REPAIR TO THE SERVICE CENTRE.
also, dont forget to write: " please change my RF/MAIN BOARD" otherwise, they will change ur backup battery only, and this wont solve the problem.
i got mine fixed, and i get new IMEI number as a result. first, they replace the backup battery only, and WITHOUT CHECK it, send the phone back to me. im shocked to find that it still had the same problem. made a serious complaint and send it back, this time the manager take care of my phone directly.. hehhehehe.... well, thats the story... thx for all of u that read n give comments about this problem.

Backup Battery did not recharge any more

Hello,
My backup battery did not recharge any more. Now, I can not even turn it on (the main battery is fully charged). In my area, there is no replacement.
So, what should I do now to make it work again?
Thanks

your post is a llittle tricky.. how did you know that the backup battery did not charge? and the main battery is full? when you can't even turn your XDA on?
have you tried to hard reset your phone? it might just be a software problem..

I had a trip for 2 days without my xda, and when I came back, I could not turn it on, I guessed that the battery is empty. So, I put it on the cradle, nothing happened. I noticed there were a socket on the cradle to put the second battery. I removed the main battery and put the main battery on the cradle. The led showed in red indicating the main battery were charging. And I put my xda on the cradle again, the red led showed too. After a while, I noticed the led changed from red to blue. It indicated that the main battery is full. I got the main battery out of the cradle. But my xda still in red. I tried for several time, nothing changed. And I put the main battery into my xda. It turned on. And there were a message saying "The backup battery is extremely low, please change or recharge as in the manual". I ran the battery application, it said that the main battery were 100% and the backup battery were 0%. The software started to install like to make a hard-reset. When it finished installing. It were soft-reset automaticely as usual. But the backlight of screen is turn off, and the picture look dummy. That ware exactly the time I can not turn my xda on anymore.
Now, there is something so strange with my xda. When I put it on the cradle without the main battery, the led lights in red in about 20 minutes and then turn off automaticly. But when I put it with the main battery, nothing happen.
I did try for hundred of times, but nothing changed. I guess that my xda is dead.
So sad.....

Maybe your XDA has a problem in its charge pins.
You should let it checked by someone.
I had the same problem as you before, but I exchanged that XDA with the new one :roll:

did you actually hard reset your phone yet? something like this happened to me two nights ago.. my phone went low on batt so i charged it and it was ok then so i turned it off so that it could charge better.. when i came back to check, i cant turn it on anymore so i disconnected it from the charger.. i took off the battery and placed it back.. but my phone didnt respond anyway.. no lights no nothing! my last resort was to HARD RESET my phone.. by placing back the battery and holding the power button while i press the reset button with the stylus.. and voila it's up again..

thanks for everyone, I did find out the problem, that is the backup battery,
I openned my xda and remove the backup battery, It works just like before. I also experience that If the backup battery is dead then we must remove or change the new one then the phone will work. It will not boot or charge with the dead one inside.

Why take out the battery and charge it separately ?
Just put the battery back to xdaII and place the xdaII in the cradle and charge it together. :roll:

im very sorry for my late reply.. if only you recieved it earlier you didnt have to open your XDA and void your warranty.. but it's good that it's ok now!

same here
i have exactly the same problem with my backup battery...i just got my xda 2i today and I tried to charge it up the main battery quickly went up to 100% but the backup battery has stuck into 75% and after a while the orange light become green as if it has charged. It takes either a soft reset or I need to disconnect (either from cable or cradle) and connect again in order to become orange and probably to start charging again...
what's wrong with the damn thing?

xda2 wont turn on

my xda2 has stopped working
i tried switching it on and nothing happens.
Thought it was the battery but have replaced it with my spare one. same problem
wont charge from cradle or wall charger (not even the led lights up)
light turns red if no battery in and charger connected.
tried reset (soft and hard)
is it time for a new one or can it be fixed?

XDA2 won't turn on
It could be the locking switch in the battery compartment.
When you move it to remove the battery it uses the backup battery to retain the memory contents (you get about 20 minutes so I read somwhere) and when you lock it again the battery becomes enabled.
If this is faulty then no XDA. One thing I found out to my cost is if you move the switch without the battery in, when you put it back in and turn it on it's done a hard reset and everything's gone.
You said the battery is charged but just to be sure, stick it in the charger slot on the stand for a while and try again. Putting a flat battery in by mistake has the same result as messing with the switch.

I dont know why it did it but i left it without a battery in for about 2 hours and put the battery back in, and now it works.
Hard reset as you would expect !
