Specs: Windows 10 - Windows 8.1
I really need to update my bios but my battery is dead ( only works when plugged to the wall) is there a way to do so on Toshiba computer ?

Back story
I bought my computer in 2014 with bios 1.0 and windows 8 when win10 arrive I did the update but since couple of years the update from windos10 was not working . I finnaly true to look why and window support told be : you can’t run update because the bios is not up to date . So I tried to updat bios in win10 didn’t work ( had An error message saying no bios can be flashed) so Toshiba tech support told me I should install win8 to try to run the update for the 1.4 bios from win8 instead of win 10 . Now the error I got running it is that : Power state is not safe for bios update please check AC battery status .
Is there any way to bypass that and make the update to bios 1.4 ?
Help me please
Thanks a lot

"Power state is not safe for bios update please check AC battery status"
CAUTION: If the battery charge is less than 10% you may be able to force the BIOS to update from within a DOS environment. A failure during this process may result in your system becoming unusable and users must proceed at their own risk.

Hi Maude,
I am suspicious of the advice to update a 2014 bios in order for W10 to run.

Updating a bios should be the last resort and only if one is suffering the problem(s) it corrects.

If you used the free update to W10, over time issues develop.
Amazingly reinstall a purchased W10 and generally most disappear.

If a bios update fails midway, you could end up with a doorstop.

Generally oem Batteries are inexpensive .
Even if cost is £20 or more and fail after a year, that amount is Peanuts.

Good Luck - keep us posted.
