I have a Toshiba laptop, model E45t-a4300. Currently, want to replace exited existing
HDD by new SSD, but I cannot boot into SSD after restarting in installation
process. I think that BIOS is the main reason.

Current BIOS version is 1.3, and final version in support site is 1.5.

I want to update BIOS but it requires both Battery > 20% and AC adapter is
plugged in. My battery is dead around a year, and no other battery to
replace. Is there any way to update BIOS without battery ?

Thank you.

No, not that I'm aware of. The battery is required as a backup in the event AC/DC power fails. You don't want total power loss during a BIOS flash, it will likely ruin the update and leave the computer completely inoperable.
I know, but I just want to find is there anyway to try. Thank you.
