A: Users who surf the Internet frequently for at most half a year should open the shell of the equipment and clean up the dust inside the equipment after the power is cut off. B: Over-voltage, over-current and heating of the equipment lead to overheating protection; Take the equipment out of operation (i.e. slow, delayed, repeated startup, disconnected, delayed, disconnected, disconnected, automatic shutdown, crash, etc.); ★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy it ★★☆◆▼●■ One: When the signal-to-clutter ratio (the ratio of signal to noise) is small, the useful signal is hidden by noisy stray signals (especially the intersymbol interference between symbols), so that the receiving path cannot correctly extract the useful signal from the noisy signal, and the judging circuit cannot correct it. Serious delay will be dropped (slow, delayed, repeated startup, dropped, delayed, dropped, interrupted, disconnected, automatic shutdown, crash, etc.). Use a noise meter to measure whether the noise level is within the allowable range, or use an oscilloscope to observe whether there is intersymbol interference. You can also take the following measures to deal with it, and do a good job of grounding shielding of the equipment. A lot of interference comes from poor shielding and poor grounding. ★★☆◆▼▲■ This answer belongs to "harmonious" individuals, and it is shameful to copy ★★☆◆▼●■ 2: Receiving level: the received signal should not be too low. If it is too low, it will not reach the required amplitude of the receiving path, and the equipment will not work normally; If the level is too high, the front circuit of the receiving path will be saturated or burned out. Therefore, receiving level adjustment is very important. Use the level meter or oscilloscope to adjust the receiving level at the connection within the appropriate amplitude range. ★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy ★★☆◆▼●■ Three: impedance matching: the connection points must be impedance matched, and impedance mismatch will lead to reflection attenuation, and the signal will not work normally no matter how strong it is. 1. Put the equipment in a safe place for people, first disconnect the power supply, then open the box cover of the equipment, and use air convection to strengthen contact with the air for natural heat dissipation; ★★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy it ★★☆◆▼▲●■
2: Add a micro fan to the equipment to increase air convection and carry out forced heat dissipation;
3: If you are in IT, I suggest that you add heat sinks to the heating parts of the equipment after disconnecting the power supply.
4: After the equipment is disconnected from the power supply, drill more holes up and down the equipment with a 3mm drill bit to strengthen the air convection and improve the heat dissipation conditions; ★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy it ★★☆◆▼▲■ < P > 5: As for the ventilated and dry place of the equipment, it is best to make an insulating heat dissipation bracket (also available in the market for notebooks) to support the equipment for natural heat dissipation; 6. After the computer is used for a long time, when the silica gel between the CPU and the heat sink dries up, the CPU will be seriously heated, which will produce slow, delayed, repeated startup, dropped line, delayed, dropped line, interruption, disconnection, automatic shutdown and crash. Re-coating silica gel can restore normal use. ★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy ★★☆◆▼▲●■
C: Clean up the garbage debris and IE cache generated by surfing the Internet in time: organize and run the C drive regularly, which can appropriately improve the running speed.
D: synchronize ADSL equipment first: power off the equipment and restart it. E: Software settings are reasonable, so that 3 items are not installed: informal software is not installed, P2P (resource-occupying) software is not installed, and infrequent software is not installed. Turn off all unnecessary network connections, such as Thunder BT Donkey; ★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy ★★☆◆▼▲■ < P > F: Optimize the network: people will produce garbage just like eating, not cleaning the table, not washing the dishes, not cleaning the cooker, and the computer will gradually behave as slow, stuck, delayed, repeatedly started and disconnected. Therefore, I personally recommend using some gadgets: such as Super Rabbit, Optimization Master, Master Lu or 36; Get into the good habit of cleaning up the garbage before going offline. G: At least one valid and genuine antivirus software: the firewall is properly set (not too much or too high); Viruses can make computers slow down, crash, drop lines, get stuck, restart repeatedly, and shut down. H: Network card problem: The network card has appropriate bandwidth, stable operation and good heat dissipation. Do a good job of grounding, separate the strong and weak signals and separate the high and low frequency signals; Good shielding grounding; When surfing the Internet, try to avoid the rush hour. ★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy it ★★☆◆▼▲●■ As long as you do it carefully according to the above, the equipment will work smoothly and your mood will be comfortable; A computer with low configuration can also make you very satisfied; Otherwise: computers with higher configuration will also have frequent failures; Dress like a man (sketch: Peisi Chen among the good guys and the bad guys: No matter how good clothes you give him, he doesn't look like a good guy! ), clothes are not high or low, and cleanliness is good. No matter how high your configuration is, if you don't use it according to the computer safety maintenance and use method, you will have frequent failures and accidents. Many failures are man-made. ★★★☆◆▼▲■ This answer belongs to a "harmonious" individual, and it is shameful to copy it ★★
