How can i turn on wireless adapter on the IBM thinkpad R40 laptop.I can't see the wireless adapter switch.......the drivers are already installed successfully.Please HELP!!!!!!!!!!!


the r40 has no hardware switch. it has a software switch. you must first determine what type of wifi card if any is installed. most of the stock cards are intel or cisco and the ibm support site has the software used to control them. sometimes, thru the network connections, windows can take control if the drivers are installed

My R40 Thinkpad loses the system date & time after being shut down for a while. However it does not lose it if only shut down for a few minutes. Any ideas please?


you need to change your cmos cell on motherbord circuit for that open back side cover and then you can see cmos cell on motherbord circuit.Change it pur chase new cmos cell.
Your old cmos cell has not enough waltage so your bios settings are not saved when you turn off the power.

Here is a link to all the drivers and software you need to put back on your R40 laptop. The one you were asking about is a bit more than halfway down the page, listed under ACPI Power Management. http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-46024
