Sir, yesterday, I purchased a Lenovo S10-3. After installing Windows 7 Ultimate x86, it worked pretty fine. Today, I discovered a SIM card slot under the battery and decided to test it. I inserted it and started the windows. So, I removed the SIM after shutting the laptop down and then restarted it. Since that startup, WiFi adapter is not able to pick up any signal despite it appears in Device Manager. The Wireless option in BIOS is enabled and Wirelss light (2nd from right) remains lit till windows loads. As soon as windows loads, the light gets off. The wireless switch to the left of Netbook panel is of no use. Windows doesn't makes a sound, if I enable or disable it. And Bluetooth adapter has no signs of it under windows. I reinstalled the windows after a clean reformat but problem insists. All the drivers also get installed except bluetooth. The setup says no bluetooth modem found. PLEASE HELP!
