I wanted to ask about this because it didn't happened to me before with other linux distributions (i.e Fedora or Mint)

For whatever reason the HDD in the laptop runs very hot, so hot that is really uncomfortable to write with my hand touching the laptop.

I've tried several software pieces to check what may be happening and I detected a high I/O from gala.

  • Why does "gala" have an I/O percentage so high?
  • Is this normal even in idle state?

Any suggestions on what else to check or what can I do to lower the temperature for the HDD would be greatly appreciated.

  • You might do a smart test on your hdd. It might be a faulty drive. – Mrpopo666 May 4 '16 at 7:18
