    It should be that there is a problem with the driver IC4953 and needs to be replaced.

    According to your texture, you can see that the driver is already installed, and you are currently in this situation, I think the reason may be:

    It was a Vista system from the factory, and you changed it to an XP system yourself. After installing the XP, I found that the indicator light of the wireless network card was not lit, and it was invalid no matter how I switched it, right? According to the research, the cause of this failure is that you have enabled hibernation or standby under the Vista system, resulting in abnormal power management mode, which cannot be activated even after you install it directly into XP.

    You can reinstall the XP power management software (English Cut) of Zhaoyang K43 or E43, or flash the BIOS.

    Don't look for those, you don't even have a wireless card. Go to the Lenovo main station and go to the next wireless network card driver of this book.,Just install it.。

    Open the folder where you installed the power management driver and start the utility.

    Then press fn+f5 to pop up a window and turn on the wireless network.

    First of all, what system do you install, is it win7 or xp, if it is win7, you have to consider the problem of the driver, you can find the driver matching your machine on the Lenovo official website, if it is an xp system, it does not support independent graphics cards now, and there are some functions that cannot be used under xp, it is recommended to replace it with win7, and then solve other problems.

    Not lit. Does it work? You opened it separately on the Internet! Just enable it.

    What about your other icons?

    If the others also do, then it can be pulled for sure.

    It's that your monitor has a problem pulling.

    It's less than a hundred.

    XP click on the desktop network neighbor right button,Select the property to enter the network connection,See if the wireless connection has been started or disabled,Use manual double click to see,Win7 will open the control panel,Then open the network and sharing center,Click on the left side of the page to change the adapter configuration,There is a wireless connection in it,See if it starts。 If none of the above methods work, then reinstall the wireless network card driver to try. Some laptops are set up with a wireless and Bluetooth toggle switch, you look around, if there is, turn it on and the light will come on.

    Which model of notebook of which brand? It should be explained in the question, otherwise it will be difficult to analyze.

    If it's a Lenovo, look at the panel in front of the notebook, many models have a switch that can be toggled left and right, and dialing to the ON position means turning on the wireless function.

    The figure should be correct, but the erased part of the second answer is redundant and can be omitted. The voltage unchanged mentioned above means that the power supply voltage, that is, the total voltage will not change, but the electrical appliances in the series circuit share the voltage according to the size of the resistance, and if the slip resistance value decreases, the bulb will divide the voltage more, so the voltage at both ends of the bulb will become larger, and the resistance of the bulb will not change, so the current will become larger.

    The slide is to the left, indicating that the resistance has become smaller, because current = voltage resistance, the voltage does not change, the resistance becomes smaller, so the current becomes larger. Because the voltage of the lamp, etc. = the resistance of the lamp, the current, the resistance does not change, the current increases, so the voltage increases.

    PS: I didn't make it clear, the previous voltage refers to the circuit voltage, that is, the total voltage, and the total voltage is constant. The latter is the voltage of the lamp, and this voltage will change.

    Your circuit diagram is wrong, the point of the sliding rheostat is not used, the wire under the point can be erased, the resistance becomes smaller, the voltage becomes larger, and the current becomes larger. The reason will not be said, but the resistor, voltage, and current are such variations.

    The resistance of the bulb will definitely not change! (Regardless of the change in resistance with temperature), the sliding rheostat slider is to the left, the resistance decreases, and since the supply voltage does not change, the total current increases, and the partial voltage on the bulb also increases.

    : The Bluetooth headset is turned on, and the blue and red lights are flashing alternately: The Bluetooth headset is in pairing.

    After the pairing is completed, the blue light keeps flashing.

    Lenovo G450 turns on the wireless light does not light up, and the shortcut buttons are uselessThe solution is as follows:

    2. After restarting the computer, turn on the physical switch of the wireless network;

    3. Then press fn+f5 to open the interface and click open to use.
