Recently I needed to troubleshoot a battery charging issue with an Inspiron 1700 series dual core laptop... as the battery was no longer recognized by the laptop. Is suspect the message "battery not recognized" also means the one of the cells is bad in the battery, moreso than it being a suspect or knockoff battery.
Anyway, one of the troubleshooting steps was to upgrade the laptop BIOS, but thats a catch22 as the
BIOS update requires a 10% charged battery and AC power concurrent during upgrade.
There is a verified process that I found... create a DOS bootable image on USB or other bootable media, making sure of a clean boot (NO drivers or shared memory managers running), and once booted into it... run the BIOS update with the /forceit switch. This bypassed the power check for me.
