This laptop came to upgrade primary storage to a nvme and hinge repair. Once we disassemble and reassemble it, startup screen shows no bootable device.
When F12 pressed it shows UEFI bootable devices such as USB flash and nvme but didn't boot to either devices.
Then I tried to change boot mode but it only shows legacy option and cannot be changed.
I uploaded the original BIOS backup .
.
Update:
I tried few BIOS from the internet and all of them shows CPU error blinks once turn on the laptop. I think all of those for compatible with this CPU. this one has Pentium Silver. (Intel(R) Pentium(R) Silver N5030 Processor). There are two models (3502 and 3582) came with same motherboard.
.
This case is same like this laptop.
