MAINTENANCE PRECAUTIONS
The following precautions are a reminder.
To avoid personal injury or damage to the notebook while performing a removal and/or replacement job, take
the following precautions:
1. Don't drop it. Perform your repairs and/or upgrades on a stable surface. If the computer falls, the case and other components could
be damaged.
2. Don't overheat it. Note the proximity of any heating elements. Keep the computer out of direct sunlight.
3. Avoid interference. Note the proximity of any high capacity transformers, electric motors, and other strong magnetic fields. These
can hinder proper performance and damage components and/or data. You should also monitor the position of magnetized tools (i.
e. screwdrivers).
4. Keep it dry. This is an electrical appliance. If water or any other liquid gets into it, the computer could be badly damaged.
5. Be careful with power. Avoid accidental shocks, discharges or explosions.
•Before removing or servicing any part from the notebook, turn the notebook off and detach any adapters (AC/DC or car adapter).
• To prevent the notebook from being turned on accidentally, remove the battery pack
before
you start a removal or replacement
procedure.
• Only use a power adapter approved for use with this computer.
• Make sure the AC adapter has a steady, uninterrupted power supply and is grounded.
• When you want to unplug the power cord or any cable/wire, be sure to disconnect it by the plug head. Do not pull on the wire.
• Be sure the socket and any extension cord(s) you use can support the total current load of all connected devices.
6. Peripherals/Modules – Turn off and detach any peripherals. Remove all modules and power units.
7. Beware of static discharge. ICs, such as the CPU and main supporting chips, are vulnerable to static electricity. Before handling any
part in the notebook, discharge any static electricity inside the notebook. When handling a printed circuit board, do not use gloves
or other materials which allow static electricity buildup. We suggest that you use an anti-static wrist strap instead.
8. Beware of corrosion. As you perform your job, avoid touching any connector leads. Even the cleanest hands produce oils which can
attract corrosive elements.
9. Keep your work environment clean. Tobacco smoke, dust or other air-born particulate matter is often attracted to charged surfaces,
reducing performance.
10. Keep track of the components. When removing or replacing any part, be careful not to leave small parts, such as screws, loose
inside the notebook.
BATTERY PRECAUTIONS
Only use batteries designed for this computer. The wrong battery type may explode, leak or damage the computer.
Recharge the battery using an approved system. Incorrect recharging may make the battery explode.
Always dispose of batteries carefully. Batteries may explode or leak if exposed to fire, or improperly handled or discarded.
Do not try to repair a battery. Damaged or defective batteries should be replaced.
