I bought a laptop 3 days ago and the HDD light is blinking contantly even if the computer is just sitting and not in use is this normal. If you can help and I need to change something can you please explain in steps because I don't know computer jargon
Yes this is normal behavior. Processes, background applications and the OS are constantly swapping in and out of memory, updates for various applications and the OS are often being downloaded and updated in the background. Even your AV will be doing this. No need to worry.
