PLEASE I NEED CHARGER FOR SONY CLIE CSK 002 /U

A Usb charger will be OK, make sure it's rated at 800ma or more, not 500ma as many are.

contacting by mail is not allowed here sir.

are you asking for the phone software similar to pc suite of nokia??

Since the battery is within the unit it can leak or go BELOW the threshold level of the cell wherein the charger will not work to charge the unit. However if you can confirm the battery voltage to be below, use a multimeter to check, then before replacing use a JUMP START with an external limiter DC bench supply , you can use a series resisitor of about 47 ohms with a 6-9 VDC.
If the battery takes up voltage the see if the charger will respond and the set will power.

No, the battery cannot be charged using the USB cable. You need the supplied battery charger. If you've lost it, you'll have to buy a BC-CSK or BC-CSKA charger from Sony.

Are you referring to the T615C?
You probably need to replace the internal battery.
Try a hard reboot while it's plugged into the charger first.

Either the stick is defective or the wrong format.
