When the battery is removed measure its voltage. If it is <2.6V DC replace it. The part number is 449137-001. Search online using the part number ''only'', to find suppliers that suit you best.
d.) Reinsert the RTC battery (or its replacement). usually it is +ve on top as marked on the battery
e). Reverse the above steps to re-assemble the laptop.
f.) When the laptop is completely re-assembled, connect the charger and try to turn on the laptop.
If it starts OK there may be a message about the date and time being incorrect. This is normal as the BIOS has been completely reset back to its default settings. Once the date and time have been adjusted the message won’t appear the next time that the laptop is started.
If you had previously changed any user defined settings in BIOS to suit whatever specific hardware configuration that you had for the laptop, then these will have to be set again.
