Very stange problem:
i was useing my sl-c860 to view some photo on an sd (1Gb sandisk ultra II)
plugged to the power supplier (5V stabilized for 220V)

Suddenly... black screen, no more signal!!!!!!!!!!

entered the menu by D+M

run all the tests... -> 1 sector bad in the NAND

no able to enter the terminal mode!

NAND FLASH -> OK

now able to enter the D + B mode and reboot; the screen appear and it boot but when the QT desktop load (i see the icons for half second) the screen go bleck...

The battery seem low ( L in the Low battery check menu with D+M) but if I plug into the powwer, the power led start to blink after 5 minutes!



I HAVE DONE ALL THE THINGS ABOVE PLUGGED TO THE POWER SUPPLIER!


ANY IDEA
Thanks Daniele

Hi Daniele,

and here is the answer to the 1-million-$-question:

Your Zaurus is OK, the internal charger is fried.

What happened:
Your ac adaptor fried the charger, the battery is not charged
any more.
Without a minimum battery load, the Zaurus will only go into
the diag. So the battery was simply drained while you watched
your photos -> Zaurus off.

A few bad NAND blocks are normal, you'll see them even in
a brand new Zaurus.

Now you have the usual 2 options:
If your dealer sold you that ac adaptor and it's not a original
EA-70, it's a warranty case for you :-)
If you bought the adaptor seperate from the Zaurus, you may
return it to Japan for a normal repair or charge your battery
outside using the CE-BC21 battery charger.

I'm not so sure the internal charger is fried:
if i charge the battery from the service menu i can charge the battery (very slowly and with an upper limit of 180!)
It's very strange but it seems that the charger have still some functionality!
Whst do you think about re charge the battery outside and then flesh the service menu with a 225 voltage value (or something aroun that for a charged battery!)

now the battery seems to charge in the zaurus to 165, 10 points below what flashed in the memory!

Give me some idea please!

Thanks

Hi amberti,
charging slowly is indeed a strange behavior.
In this case you may check this thread:

Maybe this would help in your case unsure.gif .

Fingers crossed,
