Clie losing all data after battery discharging

Archived from groups: comp.sys.palmtops (More info?)

I have a CLIE PEG-N770 and it does the same - but at the end of the day,
that's why you synchronise with your PC it is it not?

Hi Marcio,

my wife has the same problems with her SJ-22.
She uses it until the "Battery low" alert is displayed.
Now she has about 1-2 days for charging. After this period all data are lost. :-(

I assume, the voltage level for the battery low warning is too low.

I would appreciate it, if somebody could provide us with a tool, which displays
the warning message at a higher voltage level.

Didn't have a look at sony's website.
Does anybody know, if there is some system update available?


TIA

Olaf

That's how all handheld devices work. Power is needed to keep the data in
RAM. Your old Palm device may have had a backup battery that let you safely
remove the battery for a few seconds. Also, your old devices probably used
store-bought AAA batteries that lasted longer than the Li-ion battery in the
Clie.

P.S. Sony just announced they're no longer going to be selling PDA's in
America.

The IIIc and Vx are rechargeables. I have let the IIIc discharge
until it would no longer turn on several times and it still kept the
data.

In my opinion there is one important difference:
I assume, the Vx stops working on a higher battery level. That means, it has
enough power to keep the data for many weeks.

The sony warns you about an empty battery just before it's really empty - and
all data are lost.

Those are assumptions, but I'm nearly sure, that setting the battery warning
level to a higher voltage would help.
I'm afraid, that this warning level is part of the ROM.

So you would have to flash an update from sony - if available.
Or you could install a tool, which is able to set the warning level in RAM -
means, that you have to set it up every time after a hard reset manually.
