Nb: i didnt notice it was updating the idm on background

Any time you FORCE a shutdown during a BIOS update, you're going to corrupt the PC and turn it into an "electric brick"!

The only way I know to restore a BIOS is the Windows+b trick and that restores from a copy of the BIOS code.

If that does not work, there is no way I know to restore the working PC other than to pay a fortune to have it disassembled and have the BIOS chip replaced -- if that is even possible.

The problem is the keyboard  so i cant press win+b is there anyway to make the keyboard work , and i have a chip for another hp (not the same model and alredy programed for another pc can i use that and reflash with the correct bios or i have to buy the tool and reprogram this one currently dead

Apart from replacing the keyboard, I know of no way to do that -- as plugging in a keyboard will not work, since it won't probably be seen until Windows loads the drivers, and that is way too late in the boot process to do you any good.

Thank you i found a better way to deal with that im going to buy a min bios chip programmer very cheap and use it to format and reprogram it ,i choose that because i think on of my desktop has the same problem so instead of using my money to buy new chip and replace its better to buy the tool to repair all ,thanks for your supportThis is the pic of the tool
