    DO I have to open up the laptop to do this?

    They all look fine. they all have 4 pins all lined up like normal. Could it be where they attach to the MB?

I had the same problem on a toshiba satellite u400.
Usb over current on port ... blabla..
Please press F1 to resume or F12 to install.
F1 just ended up in a screen asking to press F2 or F12 which did nothing.
F12 did nothing.

Rebooting the pc ended in a black screen with a flickering HD symbol.

To be able to boot again on the BIOS I had to remove the battery and disconnect the plug.
Once It restarted booting on the error USB over current.

Si I took a USB mouse and tried to boot with the mouse plugged in on port , then another ... at the third port the PC booted normally with no error :)

Don't have any idea why it became faulty but it's now solved for me.

This means that there is shortage in the USB port. Check your USB ports. Definately there is USB port pins attached each other. Just open their contact. Or you have faulty USB device attached to laptop - remove it.

    If everything looks fine, then unfortunately it's a faulty motherboard.

    Or if your laptop is out of warranty then try to reset CMOS battery:

    1)Remove Laptop Battery

    2)Take off Memory Cover(underneath - square cover, Sits

    in middle of laptop 1 retaining screw

    3)Using two thumbs spread spring clips to outside and

    pull out RAM memory.

    4)Remove clear vinyl label opposite RAM memory slots in

    upper left corner( laptop battery slot is on right, DVD

    drive is facing away from you)

    5)Using a magnifying glass (unless you have perfect

    vision)in the upper left corner you will see JOPEN1 with

    a white silkscreen square next to it . Inside the square

    you will see what looks like the letter T over a U.

    Using a metal paper clip short the U to the Silver 1/4"

    post connecting the motherboard to the laptop case(this

    is you ground, it is located above what looks like a

    silkscreen outline of a chip)hold for 25 -30 seconds.

    6) Place back your RAM memory, put in the laptop battery

    and test start laptop. you should see a selection of F1

    or F2 for setup. Using the F2 gets you into the Bios

    menu where you reset the time and date.

"Over current" means you are drawing too much current from that port. If you have several USB devices attached at the same time it may be that you have too many and the system cannot supply the current needed. OR your machine isn't putting out enough current. Try unplugging everything but what you absolutely need.

Experiencing following on boot: Lenovo 3000 C200 PC Notebook Error 0701 usb current hc port. Both USB ports disabled. Any advice on remedy.

Kindly set the BIOS on start up. You may have disabled the USB. If the matter persists then check the drivers in the device manager if they are correctly installed. Or if the problem is your Operating System then have it updated by installing online updates. This would install necessary drivers. If the problem still persists then, look for a computer technician to check your laptop.

Hardware problem - not booting into windows

One of your usb ports is either damaged or has an object stuck in it causing a short. Unplug all usb devices and look at each port. Note if one looks slightly different from the others. There is a plastic tab that fits into usb plugs. If this tab is bent and touches the side of the port, it can cause the short. If this is the case you may be able to either clean out or bend back the bent tab.
