Why does the laptop not see the hard and drive?

Question

laptops

At one point, the Acer V3-771G laptop, when the power was turned on, began to write No bootable device -- Please restart system. He took out the hard one, inserted it into the system unit, turned it on. When loading, he swore that it was necessary to fix the NTFS system. Corrected. Turned on, hard opened, everything works. It is still not visible in the laptop. The CD drive is also not visible and does not want to read anything. How to be?

Answer 1

I would try to look in the BIOS to see if the disks are visible there. There are only two options (if both hdd and dvd are gone) in my practice: either controller settings in BIOS or failure of the controller / drive power circuits. If there is something with the power, the standard eject button on the dvd drive will stop working, and the hdd will stop making spin-up and initialization sounds at the start, or it will make cyclic sounds that are unusual for it in normal operation.
To put it simply - if everything is in order in the BIOS with the settings, it makes sense to hand over the laptop for repair.
