    Can you try an external mouse and keyboard? Are you able to enter the BIOS? Does the Caps lock key turn on if you press it during bootup?

My keyboard and mouse dont work. it worked before i restarted it now it does not at all


probably the human interface was disabled by something ..try to go to bios settings by pressing F2 on start and in there choose the key for optimal factory defaults..and engage them confirm with Y for yes..and after that press F10 to save the changes..and restart ..
This should activate them ..In case this is not working ..try the pad to see if it works and if it does..use it to download and install the keyboard and mouse driver from the manufacturer's site ..
http://www.dell.com/support/drivers/us/en/19
Or in worse case ...if you know that no physical shock damaged it ...you can reinstall the operation system ..or engage the system restore ..cause it seams that some updates or something you have done by mistake ..have disabled the devices..
In normal situation they should reactivate themselves after restart ..and after defaulting the BIOS ..but ..if the driver is damaged ..windows may choose not to activate and operate them ..even if the keyboard works well until boot to windows.. ..
Good luck !

THE TOUCHPAD MOUSE JUST QUITE WORKING DOES IT NEED REPLACE AND IS IT SEPARATE FRON THE KEYBOARD


It is hard to tell if the touch-pad needs replacing from the information you gave. However, I can tell you that the touch-pad is NOT part of the keyboard.

There are several things the can cause the touch-pad not to work. 1) It may have been turned off in the BIOS. 2) It may have been turned off by the operating system software or 3) You may have installed a usb mouse which in some cases will override the touch-pad. 4) The touch-pad may have a bad connection into the motherboard or into the touch-pad circuits.

I wouldn't go replacing the pad until I had tried all the other possible areas because this requires a complete screw removal from the bottom, removing the display and keyboard. Then removal of the upper case of the laptop. I do this as a last resort.

Can not get the mouse to work the touch pad is not working


Hi, first test with an external mouse, and then check your device manager, you can get there from control panel, system, hardware tab, device manager button. If there doesn't look like there is any anomalies you are going to want to check the bios peripheral device section to see if there is any options for mouse, probably will not be, bios is either F2 F1 or Delete. After that reseating the touchpad would be a good idea, sometimes it just gets loose, unfortunately you will probably need to call up a tech, as it will need to be taken apart. If all fails then it will just need to be replaced, the touch pad comes as a single part you buy with the top plastics that go around the keyboard. Suggest using model of laptop and brand when you search and to use www.froogle.com if you can, it will be cheaper.

Lenovo n500 laptop ... mouse pad not working


The mouse pad maybe faulty or the ribbon cable from the mouse pad to the motherboard may not be properly connected. Reseat this cable.
You can connect an USB optical mouse to the laptop. I prefer you use a USB mouse all the time over the mouse pad.

Ps2 keyboard and mouse don't work. usb works fine


Assuming you have checked in setup that the PS2 is turned on the other option is to re-flash the bios .
At some time someone switched the mouse and keyboard and started up the computer this can cause you to need to re-flash the bios most likely the keyboard chip needs to be replaced sorry to bring bad news .
Dell seems to have this problem yet the USB works is good where most modern keyboards and mouse are USB.
Purple is Keyboard if not color coded the closest to the outer side of case is the keyboard.
Good luck hope this helps you
PS. You may try setting the jumper pins to default the main board back to factory defaults then remove the jumper pin and leave off for first boot .When doing this be aware not to have the power cables connected to the server remove all power cords and the monitor . Prior to doing the first power up plug in the PS2 keyboard only then the monitor. Cross you fingers If you lucky your PS2 port’s will be working again if so shut down re install the jumper pin install the PS2 mouse.

Keyboard and mouse not working


it is likely the keyboard or mouse is putting out erroneous data and windows is then ignoring the ports,
try disconnecting the mouse pad or the keyboard and run with only one connected at a time if re-seating them has no effect.

there is sometimes a combo of software that may also effect the keyboard mouse input.
click on run / type msconfig
uncheck load startup group items.
click ok,
restart , check don't show this again.
and test system.

Keyboard and mouse not working


After Pressing the Power On button... Hold the F12 key or on some models it is the Delete Key.. to get you to Bios Setup Utility..
Look there in Advanced Settings or Similar to See if your Keyboard And Mouse show up..
Option 2: The Ribbon cables that connect your Mouse and Keyboard are Located Underneath the Keyboard.. Remove the Keyboard and check to see that the ribbon cables are Secure in the ports..
Changing the CMOS battery is probably not going to fix your problem.. IF your CMOS battery was bad, you would be experiencing The System Time Changing .. your Clock would Show a Different Time Year and Date...... Pulling the CMOS battery for 30 seconds or so then resetting it might Reset it, This resets the BIOS and Resets Any Connected Hardware.... On Some Laptops Doing this Is not enough, You will also need to short the J1 Jumper pin...
and Some other Laptops have an affixed CMOS battery that cannot be removed unless Unplugged OR unsoldered From the Mainboard...


Hope this info helps..

HP Pavilion zv6000 Notebook PC keyboard replaced


Probably the keyboard you got is defective. I have seen buttons working in very bad conditions. When a key doesnt work or several is bad news.

Try to get a replacement. Since you have already reseated this simply check if the flex cable is properly locked, (ear plugs or similar) and not moving.
