    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.

  • arcieri Oct 02, 2008

    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.

Hp envy dv7 laptop window 8 does not turn off, or go to sleep when closed

Hi Martin--

Sorry to hear about your trouble. When I first read your question, I automatically assumed it might have something to do with the mechanism (a latch or otherwise) which would let the computer know that the lid is shut and that it should go ahead and take a nap. While this still might be the case, there are apparently several people with similar problems so I am including a multi-step solution which will hopefully cover your problem.

Step 1:

Change your device settings:

WHY: Some devices are active - such as a wireless mouse, your network, or the HD audio - to wake or appear to prevent sleep mode. This is especially prevalent in regards to people who are always connected to their network since the advent of cable and DSL.


  1. In the lower left corner of the screen, right-click and select DEVICE MANAGER from the menu

  2. Click the arrow next to the device that needs to be adjusted. Since we\'re not sure which it might be, let\'s try a few of the more obvious solutions:

    buggerou are using a wireless/optical mouse, select MICE AND OTHER POINTING DEVICES

    * If the computer is left connected to the internet connection - or to be safe, if you are using broadband like cable or DSL, select NETWORK ADAPTERS

    * To check the HD audio setting, click SOUND, VIDEO AND GAME CONTROLLERS

  3. Double click the name of the device and a PROPERTIES window will appear.

  4. If the Power Management tab is available, skip this step

    If the Power Management tab is NOT available, click the CHANGE SETTINGS button. The same Properties window opens with Power Management tab available.

    * Note: It may ask for an administrator password; this is normal.

  5. Click the POWER MANAGEMENT tab, and remove the check next to "ALLOW THIS DEVICE TO WAKE THE COMPUTER". I know it sounds tedious, but you may have to do this for each of the three devices I listed above (mice and other pointing devices; network adapters; sound, video and game controllers)

  6. Click OK, close all your windows, and restart the laptop using the windows + C keys which will allow the Charms menu to appear on the right of your screen. Click SETTINGS, then POWER, and finally RESTART

Step 2:

Check your connected devices.


Some devices can cause/sleep standby issues. Let\'s check to see if they are causing a problem.


  1. Disconnect all non-essential connected devices such as your printer, scanner, USB drive, etc.

  2. Restart the computer with only the original mouse, monitor and keyboard connected.

    If the sleep/hibernate issue is solved, one of the connected devices was causing the problem. Replace each device one at a time until you find out which ****** was causing the problem.

Step 3:

Check for problems caused by using a keyboard or mouse in a USB 3.0 port.


When using 3.0 ports, some computers dont allow you to put the laptop to sleep using the keyboard or mouse. This usually only occurs on systems using AMD firmware so let\'s check and see if it might be the problem.


  1. Check the mouse and keyboard connections

  2. If a USB 3.0 port is being used, reconnect the device to a USB 2.0 port.

    If this is the issue, you have two solutions: Avoid using your USB 3.0 ports for your keyboard and/or mouse OR go to the next step...

Step 4:

Since it sounds like the sleep and hibernate modes worked in the past, we can always resort to using System Restore to revert the computer back to a time when the mode worked. Obviously, if the modes have never worked, don\'t follow this step.

You can perform a System Restore from the CONTROL PANEL.


If you are still having issues:

The list of possible reasons is practically infinite. I have listed the most common and their solutions above, but if they are not working, try:

* Disabling screen savers

* Preventing startup programs from opening

* Changing your power settings

* Upgrading the BIOS and keyboard software

I hope this works for you and if you have any questions, please don\'t hesitate to ask!

After not using my laptop for several months (it was plugged in however) my USB mouse will not work now when I boot up my Toshiba Satellite laptop.

Here are some trouble shooting steps you can try relatively easily....
If the mouse connects via a USB cable, try connecting it on another USB port while the laptop is on.
If it is an optical mouse, check to see if the LED(s) underneath are lit. Change ports until LED lights.
If you have another computer also with a USB mouse and it is working, try a mouse exchange. If the non-working mouse also does not work on the other computer and the mouse from the other computer works on your Toshiba Satellite laptop, the problem is likely with the non-working mouse.
Finally, If the non-working mouse is a wireless one, its battery may be dead. Try a new battery in it.

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

Frozen cursor on new emachine laptop

Before you plan to return make sure you have done some or all of this things first:

1. Did you reboot after you installed the Enterprise 2007 ?
2. Did you make sure that if its a USB mouse that it is securely connected to the USB port ?
3. Were you able to move your mouse without any problem at all before the software installation ?
4. Have you had this problem before the installation of Enterprise 2007 ?
5. Have you done all your software and windows updates ?
6. Will the mouse work when booting into Safe Mode ( pressing F8 during re-boot before Windows Vista loads) If it does then your softwares need to be updated.
7. Did you check you device manager to see that theres no yellow exclamation anywhere in the Mice and othert pointing devices or under the USB controller section?
8. Is there a legacy USB port to be activated on your computer BIOS ?

If the installation caused your mouse to be frozen then try and uninstall the Enterprise 2007 by using your keyboard and tab to the programs uninstall.

If your mouse still doesn't move after doing all of the above things
then try another new USB mouse. Sometimes you may have to wait for several seconds (even up to a minute for new usb mouse detection) before the USB mouse cursor will move. If the second new USB mouse still wont work then return it to where you bought it as it could be faulty usb connector

Computer wont start-up

If I get you right, after you plug the xternal drive to transfer some file, the system didn't come up. Right?
Well, let me assume yes. If that is the case, I will advise you to boot the system from an external disk and use it to scan the local hard disk for virus. After that, remove the x-hard disk and try to boot the system. If it doesn't work, then transfer all the files to the xternal hard disk and format the local hard disk for new use. Best of luck.

I believe your windows is corrupt.
Try to reload your operating system, i have seen the windows corrupted and cause problem like yours.
If you have usb mouse (external), use the usb mouse and you can check in device manager,
I believe you will see many "!" mark on the drivers.

so solution is reload the operating system.
Good Luck

this may be a problem relating to your system device driver files.
Try This:-
go to My Computer/Control Panel/System/Hardware/Device Manager. at the bottom of the page you will see USB.
If you have any yellow symbols ( exclamation Marks ) then the driver has been corrupted, or installed incorrectly.
if you have a system restore disk. this may solve the problem for you. or recovery cd.
If you require further assistance, please ask.

USB system is not working can try to boot from an installtion cd..but without HI options(Human Interface) you may find it's locked..sounds a lot like the Motherboard went south.

You could try to reseat the memory, but that's a low probability approach to this sort of problem
