Problem resolution:
During installation never abort the install process by powering the system off or through other drastic means. This can cause system program problems or even failure during system initialization.

Use the following procedure to properly uninstall programs:
1. Back up all documents and system settings related to the program before removing it.
2. If the program has its own uninstaller, run it directly to uninstall the program.
3. If the program does not have its own uninstaller, then select Apps → Control
Panel from the Search charm.
4. From the Control Panel, choose Programs → Programs and Features.

Troubleshooting Problems Hard Disks
Problem: The capacity of the hard disk, as indicated by the system, is less than the nominal capacity.
Troubleshooting and problem resolution: For computers equipped with the
OneKey Recovery feature, the system recovery feature needs to occupy some hard disk space. This may account for the apparent hard disk capacity deficit.
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.

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.
The following are general methods for cleaning the components:
• You can use a soft cloth to remove dust on the surface of the computer, the monitor, the printer, the speakers and the mouse.
• You can use a vacuum cleaner to clean in otherwise inaccessible corners.
• To clean the keyboard thoroughly, shut down the computer and scrub it gently with a wet cloth. Do not use the keyboard until it is dry.
Do not do any of the following:
• Allow water to enter the computer.
• Use a heavily dampened cloth.
• Spray water directly onto the surface of the monitor or inside the computer.
