Re: Alienware 17 R3 (LA-C912P) Powers on then powers off after 4-6 seconds
No. The battery manufacturing date is not linked to the BIOS version. In general practice, do update your motherboard BIOS to the latest version as the latest version likely fixed some bug reports.
If the battery is reporting 0% then the communication between the BMS (circuit board that is buried inside the battery pack) has failed to function with the logic board bus master.
Battery packs use a 2 wire communication = I2C / SMBUS (basically the same interface) - using this 2 wire interface, the host (aka bus master) can ping the battery using a special I2C address. Then it can extract out the serial #, charge level, etc.
Using an Arduino you can dump out the same details as has been proven by another tech on this forum.
If you are able to charge the battery then the charger IC is putting out the high enough voltage onto the battery pack leads to allow for this battery to charge.
At least we know that the chemistry of the battery cells is OK but we do not know if the # of charge cycles is high / low / count. If there is an option, return this battery pack under the premise that the battery is not being detected.
Or at least test with another (ideally fresh) battery. Amazon is great for this form of testing and perhaps that is the only fault with this laptop.
Since the battery was manufactured in 2021, I'll probably have to get the BIOS updated to the 2021 version.
