If you have tried every USB port and you use another USB device to it.. You may check the device manager and check if the USB controllers are disabled.. If not, you may click View and then click Scan Hardware Changes.. If still won't work, that is time that you call lenovo and have you laptop replaced defective USB ports..
Try removing all ports from your laptop, then reboot, and then create just one USB port. Also, go to your hardware devices and make sure your usb ports don't have any question marks or yellow warning symbols. Be sure first that the drivers for your USB ports are installed and working first. This sounds either a faulty USB cord, which does happen, or USB drivers issues in your laptop. The printer is probably not the problem here.
if the usb detects other devices and not your drive,the drive itself may be faulty.If you plug in other devices in the usb and it detects them the usb drive or its connector is most likely bad.If it won't detect any devices the port is bad and drivers won't help.Possibly a motherboard issue.
You may have a problem with your drive or the usb ports so we need to check both. The green light usually just means the device is getting power.
The first thing to do is unplug the drive and reboot the computer. Make sur eit has finished booting up completely. Then plug it into a different usb port NOT the same one. If it detects and works it was just the operating system or motherboard not recognizing whats called a legacy usb device.
Next we want to try a different usb device in the computer to make sure the ports are working.
And we want to try the drive in another computer to make sure it is working.
At this point you will know if the problem is your drive or the port. If it is the drive you can get it runnning again sometimes by taking the actual drive out an dputting it into a new external drive enclosure kit.
I had a client with this same issue. However, her issue was that the top left USB port would only accept flash drives. Your external harddrive is probably not getting enough power from your USB port. Try using two USB ports (you can get a connector for this) to power up the external harddrive.
