5 blinks on CapsLock and Numlk

@moradmorad86446 the 5 blink code usually means you have a motherboard failure. This can often be related to UEFI/BIOS corruption, memory errors, or a failed BIOS update. To try and fix that, perform a hard reset by disconnecting the AC adapter, hold the power button for 15-30 seconds, then reconnect and try powering on.

Anything different would mean you have to check your motherboard. For that, we will need to know the exact model of the board. It will be printed on the motherboard. Post a picture of yor motherboard with your Question. That way we can see what you see. 기존 질문에 이미지 추가하기
