with regards to the Ramdisk clearing on soft reset i think i have found the problem, it is more comlicated than i origonally though and atm there is no solution.

While i was away over hte last week i have been expeimenting with the soft/hard resets in WM5, combined with some reg modifications i tried tonight i have come to the following conclusions:

With a BA running WM5 the soft and hard reset are fundamentally different from 2003se. with 2003se a 'soft reset' would keep the ram alive but restart the OS, a hard reset would clear the ram and storage. I noticed that to perform a WM5 'hard reset' there is no need to hold in the power button - it does nothing. a 'soft reset' and the record + camera buttons do exactly the same. So in WM5 there is not a hard and soft reset, only one type of reset and the option to format the storage (restore factory settings) unfortunatly for us this one reset is 'semi-hard' when compaired to 2k3, it doesnt erase the storage, but it does erase the RAM.

Basically with a BA running WM5 there is not currently a way to 'soft reset' int he 2k3 term of the phrase (keeps the ram) and we will allways lose any data/partitions in it on any WM5 reset.

I believe this is due to the fact that native WM5 devices have no need to kepp thier ram alive when reset, so the functionality was not programmed into the core OS and it is way above my skill level to implement it (Maimach , Buzz, if your reading this, please help!).

All is not lost, as a Ramdisk can still be used for tem files and storage, so long as the flags that tll the OS to partition and format it on boot are there (as they currently are).

I do both ALL the time it seems - my Ramdisk is always there with what I have installed. I try to install everything in there - so if it went missing I would notice right off the bat!

Soft Reset ie: that XP Program that does the Light/Power/Reset like windows XP [hit the reset]. Or poke my stick into the little whole next to the mic. Both ways Ramdisk stays.

My RamDisk is still there and data not lost.
It is the same as in Himalaya WM5.

I will also confirm.. pressing the reset button does NOT clear the ramdisk.. if the backup battery dies it will though.. Midget.. what WM5 base are you running? Helmi or Bepe?

ok what i think has happened here is that my ackup battery is duff, anyone know what one i need to buy to replace it?

however what i wrote about the power button not being needed in a hard reset still applies as Black6spdZ tested and confirmed this for me. Just a normaal soft reset and the two side buttons is needed.

The battery you need is VARTA V18HRT
I don't think you need the varta brand name, and i'm assuming that it needs to be a recharable.
I think mine may be dying too because if i take the main battery out for even a mintue it says the backup is critically low.

you can order them here http://www.batterystation.com/varta.htm
and a google search reveals more, but everywhere i've looked it's called a special order battery, so we probably need to round everyone up and do a group buy.

That cover was a pain to get off, just apply steady force with something like this hook and make sure you are not prying against any components (used the sd card slot)

Willpower102- nice post.

My backup battery is behaving very much like yours. Lose power for >30 seconds and you're risking data.

Count me in for 2 batteries on the group buy, assuimg we get enough takers.
