I recently got a hard disk - (3F0) error and I tried almost everything on youtube, changed it to boot on legacy support, I tried draining the battery, but there's one thing I haven't tried, system diagnostics, as my f2 key hasn't been working for a mysterious reason. Is there any way I can fix the key, access system diagnostics without f2, or fix hard disk - (3F0)

If this is a new laptop, it most likely came with UEFI enabled by default; therefore, changing it to Legacy mode not only accomplishes nothing, it ensures the PC will no longer boot into Windows.
Also, 3F0 nearly always indicates that the hard drive has failed -- and those can not be fixed; instead, they have to be replaced.
