Question about Acer Aspire 5100 Notebook
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.
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
Here is the link for all the downloads for your laptop
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 v22.214.171.124.0 and Elantech v5.0.36
Again, try to hook up a external mouse and keyboard

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

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

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.
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
