    I sawe a post on techrepublic that help me. I have a Aspire 5100 that I purchased im May 07. First I started having problems with USB ports. Then my keyboard and mouse froze and I couldn't get in to access anything. I tried external keyboard and mouse through USBs and nothing. The post I read said to use a PCMIA card with USB ports. I was able to bypass problem and now I have temporary access to my computer. I believe there is an hardware/motherboard issue with this model. I will contact Acer again. If I dont get some help I will look into something legally. You can email me at if you have similar issue. Thxs

    Have the same problem with keyboard & mouse. I was told its the motherboard. I have also been researching this problem and found numerous complaints on other sites. I'd like to know if its possible to buy the motherboard and fix it myself, seeing I'm now passed the warranty date... Anybody try this yet?

    I have had this Keyboard / mouse problem with a few Acer 5100 laptops and have not found a way to fix it. But I have noticed that if I boot the computer to a Live Linux CD I have full keyboard and mouse functionality again (yes even if I can not press F2 to go into the BIOS) Only certain Linux distributions seem to work, I have had luck with Slax Kill Bill edition and Ubuntu 7something. This wont fix XP but at least you can use the laptop.

    Same problem here too! I had my 5100 for less than 2 years and the keyboard/mouse/usb went south. :( When I called Acer they just said .. "$199 to fix minor repairs".

    Would you please boot to a desktop and then:
    Press and hold the Fn key plus the F7 key once;
    Press and hold the Fn key plus the F11 key once.

    After each sequence release both keys. Does your keyboard and touch pad return to normal?

When starting and the computer, and the acer screen is displaying, hold [FN] key and press [F6] off and on. If the screen flickers to blank and back, then leave it on the blank screen let go of all keys and wait to see if it boots up to windows screen. If it does then keyboard, mouse and USB functions should be restored.

If still no keyboard, mosue, USB function, and the computer does boot to windows screen, then try [FN] key and [F7].

I just had mine fixed by Unfortunately, this is a motherboard problem but they were a little cheaper than the others since they were able to fix the I/O controller (which is the culprit) and not replace the whole motherboard. So with shipping back and forth it still cost me around $250. :( ...but... they did a great job and I'm and running!

Why won't my wireless mouse and keyboard work with my Acer Aspire ZS600 All-In-One PC?

Well, to get started I would need to know what operating system your using. For all of your USB ports to stop working, Something has corrupted your device manager or has re-configured your startup. If your using Windows, start in safe mode and try system re-store to a date when the system was stable.

Are you using an USB mouse? If so you may like to try another USB port or there might be some wire to the USB port not plugged right. You can check the printing on the motherboard to see how it should be plugged. (There is several wires for each USB port with a certain order into an plug on the motherboard when the USB port is not on the motherboard). You can check the power and make sure it is connected well and enough for everything. Other options will be to use other mouse like wireless mouse or PS/2 to USB converter to make a PS/2 mouse an USB mouse or vice versa. Checking motherboard and measuring every voltage could be very complicated.

Keyboard and mouse not working

is your mouse and keyboard wireless?

If so your connection may not be set up right.

If your keyboard and mouse are wired with USB port plugs then you could have either a faulty cord or USB ports in your system. Try using the keyboards on another PC and see what happens. Also you cannot connect a keyboard and mouse after the system has booted into windows and expect it to work. Either way your system will think nothing is attached until you reboot. Try this out and see what happens.

Sony vaio laptop is turning on but the keybord+mouse not working

If your Keyboard and mouse are PS2 type, turn off your system, unplug them and try a USB type mouse and keyboard instead. If you are already using USB type mouse and keyboard, then try plugging them into different USB ports. Bootup in Safe Mode if possible. If you do not have keyboard functionality during the initial boot process, you may have sustained damage to the motherboard. The fact you mentioned a noise (speaker type?) and then lost component function, would indicate a possible hardware failure

Hello, i currently use a IBM desktop with IBM keyboard and mouse but i just bought a microsoft wireless keyboard and mouse which i just installed into my desktop using the installation CD. They are both...

Hi Tony,
It appears that you have an IBM desktop whose BIOS isn't capable of booting off of a USB keyboard and mouse device. Older computers used to require that a PS2 mouse and keyboard be attached before booting, to prevent you from booting a machine without any way of controlling it. You have 3 options:

1. leave the corded mouse and keyboard attached and never use them
2. update the BIOS for your desktop to the newest one in hopes that the updated BIOS will allow for USB mouse and keyboard operation
3. go to a computer store and get a PS2 to USB converter/adapter. They're small and relatively inexpensive. It plugs into the PS2 port, and makes your computer think that there's a PS2 device connected, when it's actually a USB device.

Not responding, batteries good per the tester, dongle plugged in to USB port, was working fine for weeks months

Try testing the mouse in another computer if available to make sure the problem is not the mouse. Also try removing the usb dongle, re-boot the computer, and then re-install the usb dongle in a different usb port then the one you removed it from. This might bring the computer back recognizing the usb mouse. You could also go into the control panel(if you are using windows) and then into the device manager. Then try removing the mouse in the device manager and then re-boot the computer and see if that works.

Dell Dimension 3100 e10 ...usb won't work

Does the system respond to boot keys (F2, F12) when the DELL logo appears? If so the problem is with Windows drivers and probably can be resolved by reinstalling or rolling back the drivers, but how? Do you have access to another keyboard? Does the system have PS/2 ports? Do you have access to a PS/2 keyboard or adapter? If boot keys work, you could also choose F8 for Last Known Good Config (XP) or System Restore (Vista).

Have you tried different ports (front if using back or visa-versa)?
Try using just keyboard or mouse to see if one has somehow shorted. Also check the ports for any sign of damage.
