I have an Esprimo V6535. Last night my laptop shut down as the battery ran out. When I rebooted, I had lost the wireless connection. Neither the Wi-Fi switch on the front of the computer nor Fn/F1 is working. I have installed Launch Manager but this has made no difference. I have also reinstalled the Wi-fi drivers and checked the BIOS screen which says that Wi-fi is enabled. The Device Manager is not suggesting any problems with the network adapters. Other devices can connect to the wireless network so it is definitely a problem with the laptop. I am at a loss for what to try next. Please help!
