Question about Acer Aspire 5100 Notebook

5 Answers

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.

    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

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.

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 !!!

When i start computer the screen stays black and it beeps


Perhaps you've built a computer and are turning it on for the first time, or you've owned this computer for awhile.


Either way, you may encounter an issue where the monitor shows a black screen and the computer is beeping.


There are several causes and solutions for this problem.


Refer to your motherboard manual, since the motherboard is the beeping device.

These beeps are like Morse code, and each "beep code" is explained in the manual.


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

Unresponsive keyboard


Replace the keyboard. They're readily available on ebay. Also, try plugging a usb keyboard in & see if it still happens. If it does then forget replacing the keyboard. Instead you'll be needing a motherboard.

Keyboard


No keys on my keyboard work. Cause: This issue is often caused by either a bad keyboard, bad interface board, and/or bad motherboard.
Answer: Disconnect the keyboard from the computer and connect another known working keyboard to it. If this is a PS/2 keyboard and connecting multiple keyboards or a known working keyboard to the computer PS/2 port does not work unfortunately it's likely that the PS/2 port is bad. Because this port is part of the motherboard this will require that you replace the motherboard. Alternatively if replacing the motherboard is too costly or not an effective solution you could also consider using a USB keyboard if USB ports are available on the computer.

Not all keys on keyboard work.

Reference number: CH000305
Not all keys on keyboard work. Issue: Not all keys on keyboard work.
Cause: This issue is often caused by a bad keyboard or software preventing these keys to be pressed.
Additional information: This document contains information about troubleshooting a keyboard that has some functioning keys. If no key on the keyboard is working see document CH000955.
Solution: Verify that the key is not working in more than one application. It is possible that some keys may not be used in all programs. This generally always applies to the Function keys F1 through F12. If not all keys are working in all programs and you have Windows, attempt to boot the computer to a MS-DOS prompt or safe mode and test the keyboard in DOS. Information about getting into safe mode can be found on document CHSFAFE and information on how to boot to DOS can be found on document CHDOS. If it appears that a substance has been spilt into the computer, please review document CH000303. If all above suggestions have been completed or if you are not running Windows, it is likely that the keyboard and/or keys are bad and it is recommended that the keyboard be replaced with a new one.
