About Hard Disk Drive
Your notebook is equipped with a 2.5-inch hard disk or mSATA SSD (optional). The hard disk
drive is a storage device with much higher speed and larger capacity than other storage devices,
such as the floppy disk drive and optical storage device. Therefore, it is usually used to install
the operating system and software applications.
To avoid unexpected data loss in your system, please backup your crucial files regularly.
Do not turn off the notebook when the hard disk In-use LED is on.
Do not remove or install the hard disk drive when the notebook is turned on. The replacement
of hard disk drive should be done by an authorized retailer or service representative.
