Question about Acer Aspire 5100 Notebook

USB system is not working

My USB system from my motherboard appears to be not working. I was using the computer and suddenly the internal keyboard, and external mouse stopped working. I've attempted restarting, using the touchpad/external keyboard instead, but it simply does nothing. I've checked the connections for the internal keyboard, but it seems to be connected just fine. I cant even get into Windows to see what is shown about the USB in the device manager as there is no way to get INTO windows without keyboard or mouse access.

    Yes I have similar probelm. I am not sure what is the main cause behind that and how can I fix it.

  • y2Joesmith Apr 02, 2008

    Hooking up anything including an external mouse/keyboard does absolutely nothing. No lights, no power no connection. I'd love to try updating my BIOS, but it's a tad difficult to do when i cannot tell the computer what to do. I've taken it completely apart, and checked all the connections, and they seem perfectly fine.



    I've found reference to an Acer Service Disk that you can use to run hardware diagnostics with, but I can't find a copy of it anyhere. Does anyone know where i can get a copy of it?

Hi, Try removing battery, wait a minute and then refit it. This solved the problem for me. If not, a PCIMIA USB port with external keyboard and mouse may work. This appears to be a known motherboard fault.

Don't do anything until you do the following

Do you have an external keyboard and mouse that you can hook up to it. If so:

You can run a diagnostic on the computer to see what the problem is. With Dell when you see the logo screen you keep pressing F12, I am not sure what key or keys to press for ACER, they don't have the best website. Do you have a diagnotic disk. If so, run it this will run any diagnostic you want.
Keyboard, mouse, fan, motherboard, etc.

Also, is you Bios up to date.

Are your usb ports working. On a laptop the usb ports are connected to the motherboard. Check the usb ports.

I don't think it is your motherboard if other parts are working.

If you do not have your manual, here is the link

http://www.acerpanam.com/synapse/data/7117/documents/AS5110_5100_3100-ENG-OLM_0425.pdf

Here is the link for all the downloads for your laptop

http://www.acerpanam.com/flex/acerdrivers/bin/drivers.html?CFID=392700&CFTOKEN=65510280

I did notice there is a BIOS download; it is BIOS v3.14
Included in this update is your PCMICA card, which has to do with the USB ports (CardBus Controller)
There is an update for the Touch Pad Driver:
Synaptics v8.2.1.9.0 and Elantech v5.0.36

Again, try to hook up a external mouse and keyboard

Good Luck!

Nope..you 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

My Genius Traveler 6000x wireless mouse suddenly stopped working


Double check the batteries, although the lights work and the computer sees it, the voltage could drop low enough to stop the sensors.

next, try another USB device in that plug. USB port can go bad.

If the port works, it could be the wireless USB connector starting to fail, if they are bumped to hard sideways it can cause loose connections internally.

then, you might just need to update drivers. Computer update s can conflict with drivers cause devices toss top working.

Tip

Notebook Keyboard Doesn't Work


Try attaching an external keyboard, either via a standard keyboard port (usually called a PS/2 port) or via USB. If this works, the internal keyboard may be defective or have a bad connection. Try removing and reinstalling the internal keyboard; if that doesn't work, replace it.

Depending on the laptop model in question, removing the keyboard can be simple or more complex. In some cases, the keyboard can be lifted free of the system by removing a couple of screws on the bottom of the case to enable the top of the bezel around the keyboard to be removed; on some systems with a snap-apart case, you release the bezel with a flat-bladed screwdriver or special case-removal tool. With other models, additional steps might be necessary.

To determine which steps are necessary, check the notebook computer vendor's Web site for repair (subsystem tear-down and replacement) documentation. I like to use the Google search engine's site-specific search feature.

Be very careful when you work with the integrated keyboard. A fragile ribbon cable is often used to connect the keyboard to the motherboard; if this cable is loose or damaged, the keyboard will malfunction.

Have a nice repair !!!

I have an msi motherboard b75 ma g43 when i turn my system on the screen freezes at 99 appearing on the botoom right side corner of my screen.my mouse and keyboard are also not working.


Check your RAm and that you have the keyboard connected to a working port. A modern computer will not start(usually) without a keyboard. If your keyboard is a USB one then plug it into the front.

3 beeps at Startup no video


The beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules


make sure that your RAM modules and Cmos battery are securely seated

on some motherboards Cmos batteries are soldered in



Common beep codes include not having a monitor or keyboard properly connected; not having a CPU fan connected, or not attaching internal power cables to the video card.


This black-screen-and-beeping issue is most common with newly-assembled computers.


Check external cables to make sure they're properly connected.

The most important external connections to check are the monitor's signal cable and the keyboard.

If your monitor cable looks damaged or kinked, try replacing it with a spare.

If your keyboard's cable looks frayed, try a spare keyboard.


Also, a PS/2 keyboard plug (round, with holes in it, about the diameter of a finger) is often color-coded purple.


If you have plugged it into the green port in the back of the computer (for PS/2 mice) switch it to the other one.


If there is no color coding, the proper port should have a small, embossed icon of a keyboard on the back of the computer.


If it does not, refer to your motherboard manual for the correct port. If all else fails, try a spare keyboard, preferably USB (Universal Serial Bus), which can be plugged into any USB port on the back of the computer.


Check for additional motherboard power connections.

Yours may require multiple cables attached from the power supply.


There is the standard wide plug, which you know is connected properly because your motherboard is beeping.


However, there may also be an additional, four-pin cable that connects elsewhere on the motherboard.

Check the board's manual to make sure it has all the power connections it needs.


Check your internal cables.

Make sure that the CPU fan is plugged into the motherboard header nearby.


Without that, the CPU fan will not spin, and the motherboard may detect this lack of connection and produce a beep code.


Your video card also may have one or two internal power plugs that need to be attached to the power supply's cables.


These cables have unique ends on them, similar in shape to a USB plug.

Refer to the case or video card documentation if need be.


If those cables are not attached, your motherboard may refuse to boot the system.

Your video card may be faulty.


If this is a new card, it may have arrived to you broken, in which case you will probably need to request an RMA (Return to Manufacturer Authorization) to receive a replacement.


If this card was previously working for you in this system, you can contact its manufacturer yourself to receive a replacement, if the device is still under warranty.


Hope this helps

Dell keyboard doesn't work on my dell computer- xp system have tried three keyboards and none work How do I fix this software problem? keyboard doesn't show up on control panel-under keyboards


Is the keyboard a PS/2 or a USB keyboard?
If it's a PS/2, there is a good chance that you have a motherboard problem.
But try this: go to the device manager. In the control panel, click on "system" and then on the hardware tab and choose "device manager."
When that window opens, see if the keyboard appears. If not, you have either a motherboard problem or the windows system files are messed up.
If you have a USB keyboard, in the device manager you should see a bunch of USB devices. When I run into this problem, I usually remove the USB devices by clicking on each one and choosing to remove it. When the computer starts up again, it will find them and your problem might be solved.
If nothing works, you may have to use your install disk and repair Windows. Or replace the motherboard.

Problem with a dell computer..


Hi,

You may try connecting a different usb keyboard to your system. Mostly, some keyboard converted from serial connection to a usb could cause this kind of problem. In some cases also, wireless keyboard and mouse won't work when u turned on your system if the driver is not properly install.

You may also try disconnecting any other usb devices from your computer. Disconnect also your power supply then push and hold the power button for 5 seconds. Plug back in the power cord then connect your keyboard. Turn on your computer. if it doesn't work, i suggest to call your computer manufacturer and check your warranty. This could be an issue with the motherboard of your computer.

Keep me posted.

Thanks.

Jeff
