Lenovo 3000 G430 Wireless not working

My friend bring me that laptop saying that did not using the laptop for almost a year because he cannot make the WIFI adapter works. I do some checkup and found out that all required software driver is install, and there is no problem what so ever stated anywhere in the system.

Levono Wireless Device Setting

I then, search thru Lenovo website, and found some utility software that did not exist in the laptop. One of is is Lenovo Power Management (LPM) . Install LPM then the wireless button will work. To download the driver, got to http://support.lenovo.com, or you might try this LN1EGC3WW1.exe ( Lenovo Energy Management for XP)
