Technical Support surface pro 7

[user50857]

hello!
I really need help with this one please.
this surface had a bios password, but the bios chip broke while removing.
I have tried more then 5 bios and they all have the same result: "turns on, stay 5 seconds on logo and turns off".
I think maybe something else is wrong with the motherboard, but I don't know how to check it.
Does anyone has any video tutorial for repairing

Are you sure the other components were moved or not removed when you tried to remove the BIOS? Are you sure you did not make a mistake?
