How to turn on night light on ibm thinkpad

SOURCE: ibm thinkpad t42 switch for wireless network

The T42 has a bulit-in wireless network adapter and a LAN network card. T42s most likely have an Intel wireless card or less likely a Cisco wireless card.
Your wireless network adapter may have been disabled in the BIOS
and/or
The drivers for the wireless network controller has not been installed.

To check the network adapter go to the Control Panel, Click on System, click on Hardware Tab then Device Manager. Then scroll down and click on Network adapters. If you don't see your network controller or you see a yellow ? against Other devices for the Network controller. Then either it has been disabled and/or the driver was not installed.

To get the driver for the network controller you need to dowload it from the IBM/Lenovo WEB site their support/download page from a computer that has Internet access. Make sure you select your laptop model and the driver for your Windows version.
Install the driver and you then need to configure the wireless adapter to suit your wireless router settings before you can access the Internet.

Here is the link to your service manual. I do not believe the unit has a "switch", it can be enabled and disabled through the device manager on windows. Control Panel > system > hardware > device Manager, scroll down to network devices and check to see if it is listed and either enable it or disable, whichever you want.

Are you sure you have a wire card installed? If so, then try this:

1. Right-click the My Computer icon and select Properties.
2. Click the Hardware tab and press the Device Manager button. The network card should appear under Network Adapters.
   Note: If the card has a exclamation mark over a yellow background, then this is an indication that the card is experiencing a problem. Go to Driver download step 5.
   

1. Verify that the radio is enabled.
   It is possible to disable the transmitter of the wireless card without Device Manager showing any problems.
   Note: Follow the instructions provided to enable wireless card.
   
   • Most wireless cards will put an icon in the system tray (the line of icons in the lower right corner of your screen). Right click this icon and it may have a menu option to enable/turn on the wireless radio.
   • Some systems come with a Wireless Radio switch to disable the wireless radios. The wireless radio switch is usually located on the front side of the machine. If you are having difficulties with wireless connections, make sure the Wireless Radio switch is set in the On position.
     
     
     
2. Check for association to an Access Point.
   If you double-click the previously mentioned system tray icon, the configuration utility of the wireless card will appear. This utility will be able to show the status of the wireless card, showing what channel the card is using and what signal strength is being received. It may be difficult to maintain a connection if signal strength is low due to either interference or distance. For example, interference can be caused by 2.4GHz cordless phones, other Access Points in the area, and physical structures such as load bearing walls or metal partitions.
   Note: The utility can be used to configure the wireless card settings, but if using Windows XP Zero Configuration or Access Connections, you will need to use those programs to actually configure the wireless card as they will overwrite the setting of the utility.
