Re: 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...

There are 2 possible answers to this common issue, the first is that the aspire has a mouse lock. check your keyboard on the function buttons for a picture of a mouse with a line though it, hit function and at the same time press the mouse with the line through it and if its locked off this will turn if back on. The second answer is driver issues, if the first suggestion dont work I would go to the Acer website click on downloads and drivers and enter your model number. Then download and install your think-pad and mouse pad drivers and install.
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.
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
your comp is infected for sure.i`ve seen many cases where my customer`s comp is infected and they face the same problem.
make sure you have ethernet cable plugged in to your laptop so we can use safe mode with networking.
shutdown your computer.on top of the keyboard you have F8 key.the moment you`ll press the power button to turn on the computer start tapping F8.
advance boot up options will appear.
select safe mode with networking
try restoring your comp to a previous time when it was working.
if it doesn`t work don`t worry just follow the steps below.In any case you have to clean virus out of your computer.
download,install and run this software.after running the scan clean all the infections and restart your comp.
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.
On your laptops power management settings, you will probably find an advanced tab.
In there you should be able to assign the power button to 'Shutdown', as it is probably 'Hibernate' enabled.
The mouse problem is probably your laptops touch pad driver, update drivers from Hewlett Packard site if there are any.
