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
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.

Not able to scroll on my excel sheet

It's only in Excel you can't scroll? Can you scroll from side to side? If you have Excel 2003, try to press the "window" tab on the top and if the freeze pane is checked, uncheck it. Or if it says unfreeze pane, press that one. Hope this helps :)

How do you repair a keyboard button that has popped off

the problem IS self fixable. I just did it now to my "]" button on a gateway laptop containing 2 plastic peices underneath it. There are concepts that make a laptop keyboard work. Primarilly, a slightly bendable pair of plastic peices that are made to latch together at the middle to form an X shape, the bottom of the X containing two comparatively large slits where it seats at the base of the keyboard (tuck them in first so they both snap), and at the top of the X is 4 notches where they meet at the button's back surface to snap into. the X shape is arranged first so that you can manually lift and drop the X so it smoothly lifts and drops. After securing the primary mechanical system, you snap one side of the button to the X shape only. Then you use a very thin long peice of metal like the end of a sissor or small screwdriver to lift the middle of the bottom side of the button so the entire button is lifted to about the height it is supposed to be, then keep it there so the button doesnt move any lower when you try to snap the other side of the button firmly down. This is the hardest part of the repair since you cant really see what your doing, but as long as the button is lifted to its normal height, it should snap in and look as good as new.

Frozen cursor

The only reason your cursor would "freeze" is your CPU is running at 100%. Press "control-alt-delete" keys at the same time and find the process that overloading the CPU and close it. If you cursor never moves, your glidepad is broken. Do you have a "stick" to move your cursor? Many Thinkpads do. Usually have a red cap on it and is located near the b g h keys. If the stick doesn't work either, it's the overloaded CPU problem.

Out of date internet browster how do update this

If you're using Windows Internet Explorer, it will update automatically.

Fan error displace on my t42 ibm.I noticed the fan is working but the error do come once in a while thereby prevent the pc from working

If the fan is running but your notebook still overheats, your computer will turn itself off, and you need to wait until it cools downThe question is, why is it overheating? Try using a vacuum cleaner close to the ventilation slots to suck out any dust.If this does not solve the problem, please get back to me
