How to replace the Lithium Battery
REPLACEMENT PROCEDURE
1. Remove the Top case, Front Panel, RAM/Digital P.C.B. Module, DV Jack, Rear Panel, Front (L) P.C.B. and Main P.C.B..
2. Unsolder the Lithium Batteries: B7501 and then replace it into new one.

NOTE:
The lithium battery is a critical component. ( Type No.: CR2354-1GUFE Manufactured by Panasonic.)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.
