I have found the soloution of this problem. Check your usb port . Their is shortage in the USB port. You just check the usb port. Definately their is usb port pins attached each other. Just open their contact.
Your Problem will be solved.

I have solved my case of this problem so I hope replying on this forum will help others to fix it as well. This is a physical problem with the connection between the motherboard and the USB port. (The system reads an open circuit) What happened on my labtop is one of the four 'prongs' for the usb port got pushed back (into the center on the labtop) and unhooked the connection to the motherboard. I have a feeling that because several people seem to be having this problem that there might be a manufacture defect with the particular USB port.
The way to fix it: (*note: whenever you work on the inside of a computer wear insulating gloves and remove the battery from the computer before hand.*)
Depending on your labtop there should be an acess panel to the core compartments. My bad USB port was the single USB port hooked up close to the heatsink and processor +fan. I opened my acess panel and noticed that one of the four connections for that single USB port was loose. (Please note* the very small metal piece should be soldered very well onto the motherboard, the problem will probably be that it was pushed out of the USB connection side and it should still be rigidly connected to the mother board still.) So I simply and carefully placed the small metal connector back into it's slot so that it looks like the other three.
-If you have managed to fix this problem as well, my suggestion is to not use that USB port again. (I simply put ducktape over the opening but you might not be as primitive as myself.)
-If you have NOT been able to fix this problem from my instructions, please do not hesitate to leave a message on here or send me a message on this forum.
(I might also suggest to never buy a lenovo...you have no IDEA how bad their customer service is and obviously they havn't fixed some pretty major manufacturing defects.)

I had this error and it is indeed caused by a failure of some of the USB ports.
To see which ports have failed just plug a thumb drive into each port, if the red light on the thumb drive doesn't flash as you plug it in, that port is dead.
I found two dead ports just near the mic and headphone sockets., the third one there and the one on the other side of the case were OK.
So, I looked up the video that is elsewhere on this board on dismantling the 3000 C200, and dismantled everything until I got down to the USB/Sound card, and disconnected its connector cable, and reassembled everything again (making sure you put some heat sinc compound on the CPU heat sinc).
Then booted up perfectly.
Of course I now am down two USBs and the sound sockets, but I don't use them anyway (interesting that these blew without any use whatsoever)
However the price of a replacement USB/Sound card from Lenovo is about $75 AUD if I ever want to buy one.

My lenovo 3000 N100 has similar problem which is bios error 0701 usb.
I have followed your instruction on your post and carefully look into the USB and Soundcard socket for either dirt or loose connection as well as remove 1 USB port. I even tried to boot without the soundcard and USB.
However, I still unable to boot. The problem presists.
Could you please kindly give me more help on this thing as I dont think I buy another laptop due to budget shortage.
many thanks in advance and I really look forward to receiving you and any other members who are able to help me to solve this issue.

I can't get to the USB ports without taking the entire shell off the laptop so I can't try your fix. But is there a way to turn off the USB ports one at a time until I find the affected one causing the error? Or if nothing else, shutting all of them down so I can at least turn on the system? I've about had it with their customer "NO" service and will probably buy a new computer anyway, I just want to ensure my backup drive has everything from the computer.
Thank you so much for any help you can provide as I know nothing about fixing computers.

In responce to the last post (Jan 15th) by ginger28fan:
Unfortunately, if there is a short-circuit on your motherboard no controls through the bios will be able to help you. I also had to take apart my labtop often sometimes I was worried I would have to break it open. But (lucky for me) I was able to access the -injured- USB connection through one of the open areas for the heat-sinc. It took some very tedious playing with a flashlight and tweezers but I was able to gently place the connection back into the USB port.
Did you try looking for the USB connections in that manner?

Insert the cd of same O/S wait untill it says " windows loading files" then here eject the cd /dvd. This work for me.
