Re: my keyboard and mouse dont work, if I plug in usb...
Go into your Bios by hitting one of your f keys when your computer starts up. Look through it and let me know if you have all of the USB support turned on. After you check that we can trouble shoot further.
Am I reading this wrong? Are you saying that your keyboard does not work but your mouse will? Or are you saying that neither will work on USB?
Check your BIOS either way and let me know.
Do not rate this until we are finished trouble shooting.

Strange that BOTH stopped working. Did you check batteries?
Remove USB controller for mouse and test keyboard alone,
Then replace mouse and remove keyboard USB You should use another keyboard (USB or PS2) because your computer won't start up without a keyboard.
If both fail, test them on some othrer computer, ask a friend. Might take sust seconsds to do it.
If test on other computer shows ok, you may have some problem in USB ports.
If actually neither of them work anywhare, so no way but still interesting question, how both of them went bad at same time?
Actually I 've heard many complaints of these wirelss keyboards and Mouse. Probably there are some very bad quality around.
I had a wireless mouse and worked only for about 3 months.
There is a USB receiver underneath the battery panel of the mouse, although it looks like part of the workings of the mouse. It's only a very small thing with a USB plug on it but it is there. The instructions don't show a picture of it, so it's very easy to think you haven't got one until you look closely
Unclip it and put it in your USB port and it should come up.
There are 4 possible ways in my awareness...
Method 1: Resynchronize your device with the receiver To resynchronize the mouse or the keyboard with the receiver, follow
Note When you synchronize the mouse or the keyboard with the
receiver, put the device near the receiver and put any other wireless keyboards and
mouse at least 6 feet away.
Press the button on the receiver, and then verify that the
light on the receiver starts to blink.
Some newer Microsoft devices are permanently bound to their receiver
and cannot be reset. If your device does not have a button, skip to
If a dialog box appears on the screen in several seconds,
follow the instructions that appear on the screen. Otherwise, go to
the next step.
Press and release the Connect Channel button on the bottom
of the mouse or the keyboard.
Check the green light on the receiver. A steady green light
means the synchronization was successful. If the problem persists, try steps 1
through 4 again.
For the Wireless Notebook mouse:
This issue can occur if the micro-switch on the bottom of the mouse is
not released. Use a pin or a pen to try to release the button if it is
The following example shows the buttons to push to synchronize a wireless hardware device:

Method 2: Try different portsTo determine
whether the problem is related to the ports on the computer, use only the two
cables that are included with the wireless desktop receiver, or the single
cable that is included with a mouse.
USB keyboard and USB mouseIf the USB cable is currently connected to a USB hub, disconnect
the device from the hub, and then connect it to a USB port on the computer. If
your device is already connected to a USB port on the computer, try to connect
the device to a different USB port if one is available.
Note Only one USB connection to the computer is required, even if
your device has two USB plugs. If the problem persists, disconnect other USB
devices and connect only the USB plug from the receiver to a USB port on the computer.
Warning If you have to change a PS/2 connection, shut off the
computer, make the changes, and then restart the computer. Do not plug a PS/2
device into the PS/2 port while the computer is running.If your devices are connected to PS/2 ports on the computer,
verify that you have the following configurations:
Verify that the USB plug for your mouse is connected to the
green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2
port on the computer. The mouse PS/2 port on the computer may also be green.
If you are not sure which PS/2 port is the mouse PS/2 port, see the
documentation that was included with the computer.
Verify that the USB plug for the keyboard is connected to
the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard
PS/2 port on the computer. The keyboard PS/2 port on the computer may also be
purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the
documentation that was included with the computer.
you have to change your configuration, shut down the computer, make the
changes, and then restart the computer. If your mouse or keyboard has
both USB and PS/2 connections, try using the other connection.
PS/2 keyboard and USB mouseIf
you are using a wireless mouse with a USB connector and a PS/2
keyboard, verify that the USB mouse is plugged in a USB port on the
computer and that the purple keyboard PS/2 plug is connected to the
purple PS/2 port on the computer. If you have to change the PS/2
connection, shut off the computer, make the changes, and then restart
Method 3: Reinsert the batteries or install fresh batteriesBoth
the wireless keyboard and the wireless mouse rely on AA alkaline
batteries for power. Remove the batteries, and then insert them again.
If the problem persists, install a fresh set of batteries in the device
that you are having problems with.
Method 4: Check for interferenceItems
such as wireless routers, radios, cell phones, desktop fans,
fluorescent lights, and large metal objects like computer cases and
metal furniture may interfere with the signal of the keyboard. Try to
keep such items away from the keyboard, and check the behavior of the
Do not put the mouse or the receiver near any
electrical devices, especially transmitters such as cordless or
cellular telephones or other wireless mouse devices or receivers. A
distance of at least 8 to 12 inches is recommended. Do not put the
mouse or the receiver on metallic surfaces or objects, especially long
metallic rails or cables. We recommend that you keep the mouse and the
keyboard a minimum of 3 feet from metallic objects.
if you plug usb keyboard onto your laptop it will probably turn the touch pad off.
If no other keyboard is attached there is usually a switch to turn off the touch pad.
also if you attach a mouse this may disable the touchpad so you dont move the mouse pointer when you are typing
I dont get exactly what do you mean by desktop keyboard...but ...first I assumed that you have damaged your keyboard ..or you just are not comfortable with the one on the laptop and you need to plug one external...this is easy ...all you need it is a USB keyboard ...which you will plug and go ...all you have to do ..its just plug it in usb slot...and restart the laptop ...if you have a ps2 slot for keyboard ...it will work too..usually dont need a driver ..just plug and restart .. if you are talking about a keyboard virtual on the desktop.. you just go at start ...all programs...accessories ...accessibility...and click on screen keyboard... this will place a virtual keyboard on screen tht you will be able to handle by mouse...
switch everything over to usb...mouse and keyboard... or by a ps2 to usb adapter and test it out... one usb to ps2 adapter can handle both keyboard and mouse... if that doesn't work its either a virus or memory...
from ur update..it seems lik that it's not any soft based errors...it's hardware error..so it's better to hand over that to authorised service expert!!!!dont let anyone repair that!!!it will make ur problem much more bigger!!!!friend!!
