There are a battery module and a Kensington security slot at the notebook’s back.

The ASUS U1F comes with two batteries, 2400mAh (3-cell) and 4800mAh (6-cell). You can also buy an optional 9-cell 7800mAh battery for this notebook.

The 3-cell battery fits perfectly within the notebook’s dimensions. The 6-cell one sticks out noticeably.

The manual and spring-loaded locks are located on the battery’s body:

On the bottom panel you can find memory, HDD and WLAN compartments, a battery module, an emergency shutdown/reset hole, and stickers with model information and OS serial number.

Easy to see, the notebook doesn’t have a docking station connector, which indicates its purely mobile positioning.

The memory compartment accommodates a single slot occupied with a 512MB module. Another 512MB module is soldered to the mainboard. The notebook supports a maximum of 1536MB of memory.
