Laptop Internal hard drive not detected in bios operating system not found but works as external usb 3.0

[blufilth]

I have a sony vaio laptop, i disassemble it to fix my lcd backlight but when i assembled it all back together, it boots up no operating system found. and bios detect no hard disk.
-tried using it as external hard drive and it works with files intact inside harddrive
-tried using a different new hard drive on my laptop no hard drive detect on bios so cant install os
-tried removing peripherals, keyboard, cddrive, networkcard no results
-tried resetting bios by removing power cable, battery, ram, cddrive, networkcard and pressing power button for 60 seconds same results

any tips on how to fix this guys
for now what i think is that maybe sata pin-out on my laptop got no contact on internal hard drive
(actually all hard drive i tried are spinning when powered it just doesn't detect on bios and os installation as well not detected)
maybe it does have power cause its spinning or maybe the data cable pin-out (sata) dont have contact.
or fuse blown-out on my laptop that powers hard drive.
any help or tips.. thanks
