First, thanks to you guys & gals because your newsletters are very very very helpful for me. One of my friends has brought a new laptop with Windows 8 but what he has done is, he gave to the IT(who repairs the system) guy, the IT guy removed Windows 8 and installed Windows 7. It’s okay, but laptop headphone connection and USB ports are not working properly. Can you help to sort out this problem? Thanks.
The issue could be related to either hardware or software. Did he test out the USB ports and the headphone connection before the IT guy worked on it? If the headphone jack and USB ports never functioned, I’d suggest returning the laptop. Though removing the operating system might have invalidated any warranty.
If the headphone connection is Bluetooth and not a physical plug, there is the possibility that you are missing some drivers for Windows 7. Microsoft does offer this troubleshooting program for USB devices. 
Check the manufacturer’s website for your headphones for Windows 7 drivers. And that IT guy could also take a second look.
