    I have the same problem with WIFI turning ON and OFF.



    I discovered that the problem is with the ON/OFF switch on the right side. Bad contact? I set the switch not all the way ON (have to play with it) and then have no problem until I touch it again (usually by mistake). I think the problem is a bad, faulty or cheap micro switch.

How to on wifi


If you have a WiFi switch button(usually a button with radio logo on top), you can turn it by switching.
But, if you don't, try to find it on your keyboard (usually in function key with radio logo on it) and combine with FN key.
But, if still won't on, check your BIOS configuration.
But if still won't on, you can fix it by updating your BIOS. But I suggest you to take it to an expert to fix the problem.

Seems like your Bluetooth and Wifi settings are disabled from BIOS.
On laptops usually there is a setting in BIOS where you can disable/Enable Wifi+Bluetooth. Shutdown computer Turn on computer and press "F2" to go to BIOS settings Find settings for Wifi+Bluetooth and set it to default.
Save settings and restart computer You will be able to see your Bluetooth and Wifi.
Hope this works

Cannot turn on wireless radio on Lenovo Idealpad


Press FN+F5 button together on the keyboard to have the settings for display pops up on the screen. Check if the radio button was turned on both for wireless and bluetooth connection. If the radio button was off, just click ON and that should set the wifi to turned on. Always make sure that the wifi switch was set to on as well.

If this didn't fix the problem, kindly reinstall the wifi adapter driver by downloading the driver from the manufacturer's website. after reinstallation kindly reboot the computer.

Please leave comments if you have any other questions.

Cheers~

Acer 4720,when switched on wifi button,the light for wifi is flash and the funcion is worked.But switched off wifi button,the light is still on.How can i switch off the light?


For Windows Based Computers

If the drivers for the wireless adapter contain a setting to toggle wireless radio, it can be located using the

following path: Start > Settings > Control Panel > Right click Wireless Network Connection Icon > Properties >

Configure > Advanced tab

Here you will find a textbox with a list of selectable properties that are populated by the device driver. Once you

select a property there will be a value field with a dropdown box containing configuration options that apply to that

specific property. The name of the wireless radio property may vary because the listed properties are dependent on

each specific device driver. It should be fairly intuitive to determine the correct property if you simply have the user

read all the listed properties to you.

Many laptop manufacturers will place a physical switch on the outside casing of the laptop, so that the user can

easily toggle wireless radio. Sometimes these switches get accidentally turned off, or intentionally turned off and the

end user forgets to switch it back. The best practice in these situations is to ask the user to look for a physical switch

on the case of the laptop, possibly with a symbol of a radio tower next to it. After turning the wireless switch on, the

user will probably need to refresh their network list.

Laptops built by certain manufacturers may have a specific keystroke set up to toggle wireless radio.

Below are some examples of wireless radio software and hardware toggles that we have been able to

document:

Acer (General) - FN,F5

ASUS (General) -The F5R has a toggle switch to turn on and off the WIFI; it is located on the left side of the

notebook

Dell (General) - FN,F2 or FN,F8 or FN,F12
Dell d630 (D6xx?) latitude: toggle switch on the left side towards the front by the PCMCIA slots and headphone

jack

E-machine (General) - FN,F2

Fujitsu (General) - FN,F10

HP/Compaq (General Older models) - Button on upper left on keyboard deck
HP/Compaq (General Newer models) - Button on lower left below keyboard

IBM thinkpad (General) - Most have software switch or button on left hand side.
IBM thinkpad (model not further identified) with wireless switch on front edge of case.

Sony Vaio (General) - switch on front left

Toshiba (General) - FN,F5 or FN,F8 or switch
Toshiba Satelite has a physycal switch on front of case. FN+F8 shows wether wireless communications is

enabled or disabled.

For MAC/Apple Based Computers

MAC OS X 10.4.x (Tiger & Earlier)
Open MAc Hard Drive > Applications > Utilities folder > Set the Configure pull-down to Airport.
Make sure the "Airport Power:" says On. (This is the status or your Mac's Airport card.)
If not, click "Turn Airport On" button.

MAC OS X 10.5.x (Leopard)
Click on the: Apple Icon > System Preferences > Network > Airport > Airport Power - On/Off

Dell Latitude D510 - Turn on Radio for WiFi


This can be found in a couple of areas. Under Computer Management, make sure Wireless Zero Configuration is set to enabled. Also under Network Connections, make sure that the network adapter is showing as enabled, and is not disabled. This can be done by right clicking on the network connection and clicking enable.

This issue sounds like you may need to explain to her that the network cabling needs to be changed around so that the router recognizes the cable modem, and than she should be set.

Lenovo thinkpad R51e ,when i power on the laptop it show error271


This error message is generated when the BIOS Date and Time is incorrect. Go into the BIOS configuration to change the Date and Time. When you reboot and still get the same error message then the BIOS battery is flat and needs to be replaced and the Date and Time setting needs to be change to the current Date and Time after replacing the battery.
If you cannot get into the BIOS configuration (press F1 on bootup) or you get a lock icon in the top LH corner of the screen, this is a Power on Password symbol, enter the passsword to bootup the laptop and then press F1 to get into the BIOS configuration.

Use the following methods if you need to disable the radio and use your notebook without emitting radio signals.

If your computer has an external switch installed, use it to switch the WiFi radio on or off. See the computer manufacturer for more information about this switch.

When i log off and the next user logs on the keys on the keyboard are wrong i.e. the j is a 1 the k is a 2 the l is a 3


The number lock key has been pressed or the BIOS configuration has been configured with the NUM lock on.
Check the BIOS setting.

To release the NUM lock.
Press the number lock key once, if you press it again it will turn the numbers again. It is usually one of the keys above the Function keys (ie F1 to F12 keys).

You have an Power on Password.
The Power on Password is set up from the BIOS configuration and the password is stored on an EEPROM chip. Removing the BIOS battery will not reset the BIOS password, there are no backdoor password available.
There is a way to retrieve the password, but it requires a bit of electronic skill and a working computer to achieve this.
