I'm trying to locate a service manual/schematic for the Compaq B3000 series notebook. Needing to replace CMOS battery but I can't locate it in any of the compartments on the underside of the unit and hesitate to dismantle the laptop without knowing how to disassemble correctly if need be.
Date/Time errors with random BSOD showing system CMOS checksum bad message. Hoping it's the CMOS battery first and nothing more serious.
The model is a Compaq/HP B3800 notebook I believe was released only for the Asia/Pacific market. HP/Compaq websites have little information other than software updates and a basic User manual.
