Hello guys. I have a r510jx (x550jx) laptop from asus. It was beeping when laptop was off and unplugged both. Then asus changed the motherboard. Then came new problem of sound coming from laptop hdd. The sound that was not coming from 1st mobo and I have never heard from my sister's 2 compaq laptop as well. The hdd was making slight click sound when running laptop. I called asus and they replaced that hdd with new hdd. Now that same problem has arised with new hdd as well. Can their be problem in my mobo as their was no sound in 1st mobo from hdd.
