Neither Toshiba, nor National Parts seem to be able to explain, verify or even provide a Part Number.
I'm trying to repair an M55-S329.
All the signs point to a dead CMOS / RTC Battery. ( ie Clock resetting / slow boot / forgetting previously installed peripherals , etc etc etc )
All I want to know is
(a) What is the part number for the Replacement CMOS/RTC Battery for this Lap-Top
(b) Where can I get it ?
A real bonus would be a tear-down schematic for this model, but I'm sure I'm pushing my luck on this request !
T and NP have during various calls (a) Stated then denied the CMOS is soldered to the MoBo
(b) Tried to give me the PArt number for the main ( 6 Cell ) Battery !! (c) Tried to sell me a MoBo
Are we now at a stage where the Life of a LapTop is determined by the life of the RTCBattery ??

You have to remove motherboard to replace battery so find part number on old battery.

Yes, I had seen this. Even enlarging the images; I don't see anything resembling the/a CMOS battery ?. - Guess I'll know better once I tear it down.
Am planning on waiting 'till I get confirmation of Battery part number until I start the tear down.
Thanks for the input. Greg
