Mounting the computer onto a wall
The computer can be mounted onto a wall. Before doing this, you will first need to
attach a UL listed VESA wall mount* (to be purchased separately) onto the back
of the computer.
To attach a VESA wall mount
Note: It may be helpful to place the computer face-down on a soft flat
surface for this procedure. Lenovo recommends that you use a blanket,
towel, or other soft cloth to protect the touch screen from scratches or
other damage.
1. Open the hinge cover and remove the stand as shown below.
* VESA wall mount spec: VESA100, 100mm x 100mm, M4 bolts.

2. Remove the four rubber caps on the back cover of the computer as shown
below.
Note: We recommend that you put the rubber caps into the storage slots
in the hinge cover.
3. Remove the four screws which were under the rubber caps and reattach the
hinge cover.
4. Align the VESA wall mount with the mounting holes on the back of the
computer, and then secure it to the computer with the four screws.

Troubleshooting Problems Hard Disks
Problem: The capacity of the hard disk, as indicated by the system, is less than
the nominal capacity.
Further Technical Explanation: The nominal capacity of the hard disk is
expressed in the decimal system as 1000 bytes. But the actual hard disk capacity
is expressed in the binary system as 1024 bytes (For example, the nominal
capacity 1G is 1000M, while the actual capacity 1G is 1024M).
The capacity of the hard disk shown in Windows can be calculated according to
the calculations in the following example:
The nominal capacity of the hard disk is 40G, while its actual capacity should
be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x 1024)
= 2.79G is subtracted, the capacity of the hard disk shown in the system can
be obtained.
The capacity of the hard disk as calculated using this method may be slightly
different from the actual capacity due to the rounding of totals.
Performing Daily Maintenance Tasks
Cleaning the computer components
Because many of the computer components consist of sophisticated integrated
circuit boards, it is very important to periodically clean the computer to prevent
dust buildup. The cleaning supplies you need to clean the components include:
a vacuum cleaner, a soft cotton cloth, pure water (preferably purified or distilled
water) and cotton swabs.
Attention: Before you clean your computer, disconnect the computer
from the electrical outlet. Clean your computer with a soft cloth
dampened with water. Do not use liquid or aerosol cleaners, which may
contain flammable substances.
Note: To avoid damaging the computer or display, do not spray cleaning
solution directly onto the display. Only use products specifically designed
for cleaning displays, and follow the instructions included with the product.
