After i cleaned my laptop fan i'm facing a problem like my wireless button wont work when i press it. The problem is when my system is booting up during that time when i press the wireless key it turns on/off e.g i press and keep it on and when my desktop loads and i press the wireless key to turn it off it wont turn off, the notification says " Wireless disabled " and say for instance i did not turn the wireless on during the bootup and after my windows load i have no command over it to turn it back on it stays off, it either stays on or off. Any solutions please? I searched google alot, in one thread i found a fix with many people saying their problem got solved, but i dont know how to use that fix. That thread says the following :- -- I had the same problem with a Sony Vaio. It seems one of the updates put entries in my registry to start a Vaio Lan Manager with Windows. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run Check these keys to see if any kind of a 3rd party Lan Manager is running. If so, delete the entries and reboot. Sorry about the lateness of my answer, but I just had the problem. Good luck. -- Can anyone tell me how to do this in steps?
