 The inferior power may lead to consequences Alerter l'administrateur Recommander à un ami Lien de l'article 

Power of choose and buy is not reasonable or use inferior power supply, computer hp mini 110-3100sw keyboard may often appear bluescreen, restart, crash, program operation error and so on the condition. Or computer boot can't identify hard disk, and cd-rom and other equipment, leading to can't boot up. Generally speaking, the power supply power if can't satisfy all accessories power demand, will not be able to ensure the stable operation of computer accessories. Of course, may also due to inferior power use old element, output power shortage, which leads to the computer can't normal start. Additional cooling condition does not pass, resulting in high temperature also can appear the phenomenon such as system halted.
Power of choose and buy is not reasonable or use inferior power, which is easy to cause the computer hard disk appears bad way, cd-rom read disk capacity greatly reduced. Power is not enough may lead to + 5 v power supply output is insufficient or unstable. Due to the hard disk, and cd-rom just use the + 5 v power supply output, in the long run, the power supply instability or insufficient situation is likely to appear damage and unstable phenomenon. For many use the computer hp mini 210-2170nr keyboard users, if often meet with hard disk appears bad way, might as well pay attention to if the power out of the question.
Power of choose and buy is not reasonable or use inferior power, when the computer hp pavilion dv7-1000 keyboard encounter suddenly loses power or encounter lightning, the computer easily damaged. The role of PFC circuit can effectively ensure the use safety of computer accessories, but many inferior power is very light is because no PFC circuit. This will greatly increase the accessories damage probability. At the same time IC circuit is too single, and do not have the protection function is also computer encounter suddenly loses power or encounter lightning easily when one of the reasons for the damage.
Power of choose and buy is not reasonable or use inferior power, will cause CPU overclocking decreasing. A lot of people in the CPU overclocking, can't reach the expected effect, actually a lot of time is because power the hp pavilion dv6-3130sa keyboard choose and buy is not reasonable. Such as purchased the rated power partial small brand power, or buy the output power no guarantee of power supply, etc. Due to the CPU overclocking, power consumption will increase, the power rising sharply, when the power supply output power is insufficient, will not be able to meet the need for overclocking CPU power consumption demand.
Power of choose and buy is not reasonable or use inferior power, will cause headset speakers and other equipment noise is very big. Due to the inferior power filter function odd difference,hp pavilion dv6-3140sa keyboard plus circuit quality also don't pass, so easy to sound card operation appear unstable condition. For some high power speakers, if the power is not enough, sound box appear noise is inevitable.

 Analytic how to make wireless Internet safer Alerter l'administrateur Recommander à un ami Lien de l'article 

In the wireless network constantly mature today, toshiba satellite a205 s5801 laptop keyboard wireless network security hidden danger is becoming the focus of attention, and prevent the wireless network from foreign invasion more become a wireless network users want to face above all things.

Want to make wireless Internet safer, the following three wireless network security measures can help you achieve:

Change the default SSID Settings

In the default state, wireless network node production toshiba satellite a205 s5803 laptop keyboard chamber of commerce use SSID (initialization string), to examine the attempt to login wireless network node connection request, once the test through the words, it is possible to successfully connect to a wireless network; But because of the same manufacturers launched a wireless network node are using the same SSID name, which gave the illegal attempt to connect to wireless network of the attacker, and provides the invasion of convenience, once they use general initialization string to connect to wireless network, it is easy to build a successful unauthorized link, so as to give a wireless network security threat.

Therefore, at the first installed wireless LAN, you must timely login to the wireless network node management page, open the SSID setting options, resetting the initialization string, had better let a person hard to guess to; And in order to more effectively avoid illegal links, you'd better in the premise of the condition allows, cancel the SSID network broadcasting, this can will hackers toshiba satellite a205 s5804 laptop keyboard opportunity to the minimum.

Of course, the wireless network node of the SSID name change, you must also be in workstation wireless network attribute Settings window, remodification SSID service name, such ability make sure your workstation successfully access wireless network. In ordinary workstation modify SSID name actually very simple, as long as you in the wireless network connection properties window, click "wireless network configuration" label, then in this tag page, select the wireless network node name, click on the "property" button, and then pop up "relevance" tag page, direct will new SSID name input in the "service name (SSID)" in the text box, and finally click "ok" button, can make the toshiba satellite a205 s5805 laptop keyboard Settings to take effect.

Appropriate place antenna

Because wireless network node is wired signal and wireless signal conversion "hub", wireless network node of the antenna position, not only can decide the wireless local area network signal transmission speed, communication signal strength, but also can affect the wireless network communication security, to the wireless network node is put in a proper position is very necessary.

In place before the antenna, you'd better make sure wireless network node communication signal coverage for much, then based on the range size, will antenna placed to other users can't "touch" position place. For example, if the wireless network node signal transmission capacity in 30 meters of less than, and now you want to be in 100 square meters of space, build a small wireless local area network, it will be the best wireless network node placed in this space is central, and at the toshiba satellite a205 s5821 laptop keyboard same time will be other workstations in wireless network node scattered around the place, and thus is located in the other room workstation won't automatic search to your wireless network, so wireless network is not prone to signal leak risk.

If you just wireless network node will be placed in a window or wall position place, not only will affect signal foreign emission, and is located in the other side of the wall workstation users, can easily search and connect to your wireless network, in this way, your network security will be greatly reduced.

Do other prevention work

In order to better protect the safety of the wireless network, you can also according to the wireless network node itself the function different, do some other effective safety measures. For example, if the wireless network access nodes support simple network management function words (SNMP function), suggest you try to this function will be closed, in order to prevent toshiba satellite a205 s5823 laptop keyboard illegal attackers easily through the wireless network node, to get the whole wireless LAN of the privacy information.

If your wireless network node also support the access list function word, that you can use this function, accurate limit which workstation can connect to a wireless network node, and those who don't access list of workstation, is to enter in the wireless network. Consider, for example, to each piece of express card has its own MAC address, you can completely in the wireless network node equipment to create a "MAC access control list", and then will you think legal network card MAC address each input to this form, and then only "MAC access control list" shows that the MAC address,toshiba satellite a205 s6808 laptop keyboard can enter to your wireless network.

A lot of older wireless router in the design of firmware, without considering the application under Windows7 system, therefore, the emergence of a Windows7 refused to wireless router's situation.

Dr. Known:
Microsoft says Windows7 can and more than 90% of the hardware perfect compatible, in other words, Windows7 there are still part of the hardware conflict problem. At present, the wireless router Settings have been ShaGuaHua, upgrade firmware is a piece of cake, ready to use Windows7 users the best wireless dell xps m1710 laptop keyboard router timely update the firmware.
