  thanks for the response  today update, the laptop that connect to QnA CPU had to be remote from vendor (Japan) and they requested the I have to provided spare of the  Q1MEM-256SE , now, we have already bought the spare SRAM, from the different city (at least 6 hour driving distance). tomorrow  we will receive the 3 pcs spare SRAM (including battery) , because, the battery that inside SRAM of the problem CPU was already drop only 1,5V from 3V  we hope, this will clear out the trouble,  (with the assist from vendor)      

thank you for the response as your prediction,  this time, we face the problem, and from the vendor, their suggestion is same, to upgrade with curent available  control and redesign the wiring,  now we are still looking for the replacement of the extension card SRAM + EEPROM =  Q1MEM-256SE , maybe there is some file in those memory card need to be loaded and either the card is broken or the battery inside inside card is worn out  we trying to replace the CPU with the same Q2ASH (without card) still no luck however do you have experienced read this card using some converter / card reader to a PC / laptop  ? is it same with PCMCIA card or they had a different type of pin (SRAM) ?
