Internal battery
« on: November 21, 2004, 02:48:21 pm »
Does the C3000 come with an internal battery that prevents it from rebooting during battery changing?
   I got my c3000 two days ago and I charged it for about 6 hours before using it.
It worked fine except that it would reboot every time when i change the battery.
I believe that it has an internal battery otherwise the reset button would be an unnecessary design.
    I would like to know if you guys can change the battery without rebooting the device.

The internal clock is only to remember the time... When you attach the power supply, and THEN change the battery, the device problay won't  reboot...

Reset buttons are always welcome, a freeze is bad enough without having to take out the battery to force a reboot.

Shiny! - The 3000 has a reset button?

I believe that if you change the battery within a few (<5 seconds) then it won't reboot.

I dont see any reset buttons!

In fact, still trying to figure out how to power down, "shutdown now" hangs it without shutting down or powering down.  Also tried a poweroff util, and it didnt run.

There is a illustration on p.216 of  the manuel which points out  the reset button

Not here.

Maybe a capacitor in parallel with the battery would allow for fast battery changing without reboot.

Anyone tried that?

so just to summarize, (and more or less answer the question), there is no internal battery in the 3000? meaning that if u take out the external battery while the unit is running, it will "die"?

another related question - so I assume the same thing will apply to the 3100 as well?

Hi all,

I asked the same question on this forum some six months ago and was dissapointed even then.  The lack of internal battery is the *one* thing I would definitely change on my C3000.  

I use three C3000 batteries and an external changer, so the "instant reset feature" when changing batteries has been a real pain.  

My solution has been to carry around a little emergency power supply for a mobile phone that has had the original moulded phone plug cut off and a zaurus power plug attached.  This takes 4 of the smaller size penlight batteries (AAA in the UK, size 4 in Japan) so its not very heavy.  I've used it for six months without changing the penlight batteries.  Since it's only used for a few seconds each time I expect the little penlight batteries will last a long time.  The battery phone changer was bought for 100yen from the local "100 Yen Shop" here in Japan (that's about $1US or 50UK pence.)  Cheap DIY solution.

Attached are pictures for anyone interested.

Jonathan

Plug came off an old wall brick transformer.  I looked in various electronics component catalogues but I couldn't find the plug anywhere.  I did recently see a few of these plugs in a backstreet shop in a Hong Kong though, if you fancy a trip...

Plugs and battery packs are available at Radio Shack.

The following worked for my 5500.
It might also work for the 3000 as well as others.

And another question if I may - what happens if the main battery runs out - I have a 5500, which is well known that when the battery runs out, you lose everything stored in the machine, and have to reinstall everything - I remember when the 700/750/760 came out the few early reviews mentioned this problem had gone away, presumably with a small internal battery to keep the data safe.  I assume the 3000/3100 still have this battery, or are we saying it's no longer there...?

the internal battery is not needed since stuff is stored in flash ram, ie nand which is non-volatile memory as opposed to volatile memory that required a current to keep the data.
