Hi, I have an Acer Aspire 5551 Laptop. Recently it was infected by a virus and I had to reinstall Windows XP SP2. After that i installed all drivers available for this model from the Acer site, and some empowering Tech utilities (framework and eSettings).But when i tried to install the driver for Bluetooth, it said "Device not found.Please check it is connected and turned on".So i tried to push the slider button on the front of the laptop, but the bluetooth didnt switch on. Before the reinstall, this was working fine.Similarly the slider button for wireless network is also not working.Then i tried to install USB driver for my LG phone, but again there was some problem. Though the LG sync software can detect the phone, but cant transfer files or anything. Once it gave some error message about some problem in COM port or some such thing.But i didnt understand it.I am wondering whether there is some basic motherboard driver which i did not install, which is causing all this ?I had already installed the chipset utility from the site. Any suggestions are welcome. thanks and regards Rahul

I seem to recall Acer also included a utility called LaunchPad, Launch Manager or similar & that had facilities for enabling/disabling some of the buttons. Have you installed that as one of the 'tech utilities' you mention? "I've always been mad, I know I've been mad, like the most of us..."

hi, thanks for your reply. yes there is a utility called "launch manager", and it has been installed. it is for configuring those few small buttons near the power buttons (for email, browser hotbuttons etc). its does not have setting for BT though. Somebody with a similar problem in another forum was suggested to try going thru BIOS and see if BT is turned on there. I could not find such a setting in BIOS. there is another utility called ePower Management, the user manual of which showed that it has certain settings to turn off power of BT and Wi Fi. I am going to install that and see if that helps. Any other suggestions r welcome.
