I had been using a Lenovo Edge laptop, and one day it died. The operation system (windows 7) was corrupted. After installing a new Windows 7, I found the computer is impossible to use – it does not find the wireless adapter and the screen resolution is low. I did a lot of google but Lenovo apparently has a lot of special hardware and it’s hard to find the correct drivers. I almost gave up.
I then tried an external USB wireless adapter from another computer and it works. So I was going to purchase an external USB wireless adapter. Then I did another search to fix the screen resolution and at this time I found Driver Detective, a program which claimed to be able to fix all driver issues. I hesitated for a few minutes when I found out the program is not free (about 30 dollars). But eventually I convinced myself to pay. To my joy, it fixed all problems, including the wireless adapter driver. So I do not need to buy an USB wireless driver anymore.
