First you need to open the Laptop then remove the USB connection of the keypad….
After that disconnect the battery and ………
Connect the power adapter…
Now switch on the Laptop see what happens …. If Laptop doesn’t start then you have to remove the Bios battery of the Laptop…..!!!!!
Try after remove Bios battery (i.e. power on)
You must got the success …..
The keyboard and touch-pad are connected to an internal USB interface, If no USB interfaces are working at all this suggests that the USB host controller (a physical computer chip) has failed.
You can try a chip-set reset; disconnect both power and battery and hold down the power button for 30 seconds (timed), this will reset all chip settings to default and discharge any static buildup but this is in no way guaranteed to fix the problem.
If the laptop is still under warranty arrange for repair.
In the mean time most of the Aspire 5100 series have a PC card slot on the side so you could use a USB or PS2 host card to connect a keyboard and mouse.
The Hub controller is a chip, surface mounted on the motherboard and is not replaceable.
When we have this kind of issue at our laptop workshop we replace the entire PCB.
As for the keyboard don't look for a USB cable, plug or socket as you'd recognise it, it's just a ribbon cable going from the under side of the keyboard, touch-pad, wrist-rest assembly to a clip socket on the PCB.Â
USB is not a kind of cable/plug/socket it's a serial connectivity standard.
Sorry about the delay in getting back to you.Realistically that leaves a fault with the USB controller but to be 110% sure try booting from a live CD such as Puppy Linux or Knoppix.
This will load a temporary operating system in to RAM and allow you to test USB without the infinite multitude of Windows problems in the way.

thanks but it didn't work with the 30s power button reset :(
I opened the laptop before you wrote ur solution, but couldn't find where the keyboard connects. Do you know where this usb host controller is located?
Yeah I saw those ribbon cables, they seem to be connected ok.
I have the same problem :( No keyboard, no touch pad. I connected external mouse and keyboard but, they're not working... My laptop has no more warranty so I called the technical service but they charge $105/hr for "taking a look" :(
I'm trying all the solution here. I hope one of them work for me. :_(
the laptops keyboard and touch pad do not work, they dont even respond to an external keyboard and mouse as well...what do i do?
