How can I keep the date information when I change the battery?

[rocqip]

Hi guys,

I have updated my Qtek 9090 to WM5. But I found an annoying problem, every time when I plug out the battery, for example to change the SIM card, the date information will lose and I must set it again when I turn it on.:(

Does anybody have good idea to solve this small problem?

BR,

What is the status of your backup battery.

Is it fully charged before AND after you change the battery.

If after changing the main battery the system reports the backup battery to be discharged, maybe your backup battery is died?

Mine does the same thing. I think our back up batteries are dead. How does one replace the battery?

[raymonds]

the date and time gets erased every time i change batteries. quickest way to get the time/date right is to connect the xda2s to the computer via activesync (or manually correct it)

I have checked the status of the backup battery from WM5 battery information, it is 100% full. Is this information believable or not? If not, does anybody know how to change the backup battery?

What % is the backup battery after you change your main battery.

Thats the key, if it says it is flat after change then your backup battery is not holding charge.

To change it I believe would entail opening your pda case and removing the old battery & installing a new battery of the same type/rate.

Don't know if they are soldered or clipped in, someone with more knowledge may shed some light.

i use the ms activesync to synchronize the date

i have the same problem.. even if i poke the soft reset button, time and date reverts to default.. september 1, 2004..

i can assure that my back up battery still works.. it loses charge and drains (my ramdisk gets wiped out) for about 30 minutes without the main batt..

I'm having the same problem as well.
Anyone found a solution to this yet?

EDITED:
I'm using Helmi_BA_WM2k5_AKU3.5_v1.4.CF2 R2
And I've confirmed this problem doesn't occur when using WM2003SE.

I have no problem with that, and i am using the same rom as you.
When i remove teh battery, first i lock the device, and turn it off, making the screen all black. now i remove it, and in less than 20 secs i swap cards.
No mem loss.

When you mean by "turning it off", you meant pressing the power button and it goes to suspend mode right?
Cuz on my Dell X51v there's a function to perform a full poweroff which I can't find in this ROM.

[raymonds]

anyone tried to remove the battery the moment just after choosing a soft reset?

1. choose soft reset
2. then when the four colored lines come out, take out the battery
3. insert new battery
4. turn on the power
5. just in case the R and G values display "NONE", just choose soft reset again

i think it's a good alternative to keep the date/time after changing batteries... i just don't know the harmful ramifications in doing so, if any...

Of course.

[wuzy]

Ok, this is strange.

I accidentally moved the battery latch when the screen was on, the battery fell out and the screen faded out quickly. But when I put the battery back in and reboot the device, all settings including date & time were still there!
So I tried the same method when swapping to my other battery and it worked as well! w00tz!

Done it a few times now with 100% success so far.:)

I use Drifter by Kopsis when I'm in wi-fi range. Drifter uses Network Time Protocol (NTP) to set the time. Thus you can set the time even without syncing to your computer.

I'm using AKU 3.5.2 with the BuildOS on default settings and i can change my battery just fine.
