Alright this seems to be an uncommon error in the Windows 7 era.

I've recently been getting "Power Surge on Hub Port" error notification bubbles on my Y480. I haven't had anything connected via USB, and the only thing I can think of that would cause it is the Bluetooth adapter. I've tried re-installing the Bluetooth drivers but the issue persists. Any ideas?

Could also possibly be the webcam if that model has one.

I got a couple responses on the Lenovo forums.

Hi BrettAm

Welcome to the Lenovo Forums.

Sorry to hear about your issue. Am going to try answering this (hope this works!

This error could be indicative of a fault or damage to a port, which means it is defective, and which could have been caused by shorting.

A workaround you could try is to disable that defective port.

Go to Control Panel >> System>> Device Manager>> Universal Serial Bus Controllers, and you will see a list of the detected USB ports on your computer.

Disconnect all USB devices from your system.

Disable each of the Intel(R) devices. Do not touch the USB Root Hub icons.

Going down the list of devices, right click and enable a single USB controller and test the port with a low-powered device such as an optical mouse and plug into a USB port. If your laptop doesn't recognize the device (wait a few seconds), plug the mouse into the next USB port until you get a response.

If none of the ports respond, disable this USB controller again, and repeat this step for the next USB controller in the list.

Hope this helped!!!

@BrettAM,

Please try Serene_Lenovo's suggestion and see if it helps. If it doesn't, try the step below.

1. Are you using Windows XP? If you are, does the Lenovo Preload Win 7 have this issue?
2. Tried updating the BIOS?
3. Try removing batt and AC adapter then hold the power button for 3 secs, repeat 3 times then put everything back and see if it helps.
4. Do a One Key Recovery - Restore factory default

If problem persist despite doing the above then I would suggest to contact support to get the hardware checked.

There are 2 x Intel 7 Series USB Controllers: 1E26, and 1E2D; plus an Intel USB 3.0 eXtensible Host Controller.

1E26 only enabled - No response from any port.
1E2D only enabled - Response only from USB 2.0 port near AC jack
eXtensible only enabled - No response from any port.

All enabled - Response from USB 2.0 port near AC Jack,
USB 3.0 on left side towards the back, but get an error saying "Device can perform faster if plugged into a USB 3 port. Only works sometimes. Resetting the hub sometimes allows it to be detected.

Test device was a WD My Passport SE USB 3.0 drive. I don't have any low-power devices handy at the moment.

This is running the Lenovo Preloaded Win 7 x64. BIOS is current as when I received the computer I downloaded all new drivers from Lenovo site. I'll attempt the reset next. I'd rather not do a factory OneKey reset just yet. That's my second-to-last resort.

I'd like to mention that I get the Power Surge error even without any device plugged in. Also, Bluetooth is turned off and the webcam is disabled both with the Hotkey and in Device Manager.

If I turn off "Intel USB 3.0 Root Hub" the error messages stop.
