Re: [Poll] Does your N900 'forget' time & date after battery change?
 

Mine forgets it and to the best of my knowledge, always has. I didn't realise it had a backup battery - all motherboards do to remember CMOS and BIOS and previous phones always have, so I thought it was strange that the N900 didn't.....

I didn't when I bought it, but do it now. Don't know if this changed after PR1.1 or PR1.2

Hey sk8erboy! I just sent you an email!
Actually, I'm talking about the backup battery.

The backup battery is a small, non-removable battery inside the phone, which is by the phone to remember the date and time!
My thoughts would be that this battery may have run out of juice.
Interesting point with hot-swapping batteries! I didn't know about that!

And thanks to all other people answering to this thread! I didn't know that this was such a widespread problem!
I also tried to see whether it mattered if I force shutdown or use the powerbutton! To me it makes no difference!

Where do i find this battery in the phone? can run out after less than a year? if that's true nokia needs to send me another one asap.

I don't know where the battery is located at on the N900, but this is how it would look like: http://www.uni-bonn.de/~nraeth/platine.jpg
That's the picture of a backup battery on the 2004 released Nokia 6230 (which I also owned).
Today, I asked a Nokia Service Center to replace it, but they said that they'd have to send it to Nokia to fix it!

You forgot the option - sometimes. Sometimes it happens and other times it does not happen. I did not find a pattern yet, and it seems to me that the time it takes to replace the battery is not the deciding factor.

Thanks, that's a good point! You don't seem to be the only one where it only happens sometimes! Unfortunately, I can't edit the poll anymore, or can I?

By the way, I found out that the backup battery is soldered to the N900 board, so "normal" Nokia Service Centers won't be able to replace the backup battery.

Here's the picture.

very interesting.
i didnt know that with the backup battery.

Re: [Poll] Does your N900 'forget' time & date after battery change?
 

As far as I remember I always had to reset the date when I take the battery out.

Mine didn't used to do this, but does now...
