The proposed use of the environment

Notebook computers more sophisticated internal structure, the general civil notebook should be avoided in harsh environments. Daily we should try to avoid direct sunlight notebook, so that chassis and internal component aging prematurely because of high temperature damage.

Many places to avoid dust using a laptop computer, desktop computers often laptop battery use friends may understand this very well. After the computer is turned on will have the phenomenon Acer TravelMate 290 Battery of static vacuum, the internal inhaled too much dust can cause the system unstable or even collapse. Notebook disassembly is much more trouble than the desktop computer, but also the internal structure more closely, the air circulation space for smaller, more vulnerable to the impact of dust, so we try to dust environment in the use of a relatively small laptop.

Many places to avoid dust using a laptop

In the thunderstorm days and should Acer BATCL50L Battery avoid the use of laptop, notebook in general built-in modem, wireless network cards and other equipment, more vulnerable to the impact of lightning, so minimize the use of laptops during a lightning storm to avoid dangerous place.
