I'd download and install ALL of the latest drivers for your laptop model from the manufacturer product page, just to be sure. Chipset, audio, network adapters and storage controller drivers. If the component is part of that laptop and requires a driver, it should be among those found on the manufacturers support page.

If this is an AMD platform, most of them will be part of the chipset drivers.

What is the EXACT, FULL model number of your laptop (Not just the series which is what you posted above) as printed on the specifications decal on the bottom of the laptop (Sometimes located on bottom, sometimes beneath the main battery in the battery compartment) or express service tag number, also usually found on the specifications decal?

Yeah, that was what I was afraid of. In which case it's likely that the USB port is simply, faulty. Not uncommon on laptops where the USB ports are subjected to frequent pushes and pulls from devices frequently being disconnected or inserted, or things that are plugged in getting bumped causing the port to be smashed from side to side.

Have you tried using OTHER USB ports on the unit, same result?

Try this, for finding the info. Go to the start menu, type ms32info into any search or run box, hit enter. On the system information page you MIGHT find the full model of the laptop listed in one of the information fields.

I guess you mean you battery is no good? Because all laptops HAVE a battery.

If the port has failed to work before and then just started working again on it's own, then it's almost certainly a physical problem with the port itself. Nothing really that can be done for that aside from get a new laptop or take it in for repair, and the repair will cost more than a new laptop in most cases.
