Hi

Depending on your description/meaning of "totally formated"

Like for instance there is no operating system, and this may help...

Maybe an F11 Factory Fresh Install is the answer.

Make, Model and OS please.
SKU: if possible by this method
WinKey + R and type
msinfo32
Read Line 9
System SKU: N6K07EA#ABU

Please do not post Serial Numbers.

Maybe a cloud recovery???

I mean I used the F11 for factory reset.

After the first process an instruction to click F1 or F2 to complete the process of which I clicked F2 because it was stated that all files would be wiped off and are irrecoverable and that's what I wanted.

Immediately after this, the laptop keeps going off and on.

I tried to do another factory reset but when it loads to 54%, it goes gives an error message saying the reset can not be completed.

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat; Re-Connect the AC adapter.

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
