Question about Acer Aspire 3100-1405 Notebook
When I boot the 3100 the keypad will not respond. I cannot enter setup or acess the safe mode option screen using the keypad. When the system get to the windows login screen I cant use the keys or touhch pad to select a user or shut down.
If I put the computer in to standby by depressing the toggle (screen closed) I can then wake the it back up using any key.
I've tried to add a USB mouse but, on all 3 ports it only flashes for an instant when I plug it in then goes out and won't function.
I suspect a Bois issue becaues windows will wake from standby using any key but the computer does not recognize the the keys during post.
I've been search the web trying to find out if there is a jumper setting on the motherboard to reset the BIOS but have not even been able to discover the type of motherboard used.
If anyone has any sugestions they would be greatly appreciated.
I have this same model and bought from tigerdirect around Nov 06. I started having problems with mine around the first of Feb.08. As you noticed it is a few months out of warranty. My keyboard and touchpad will not respond during boot up. I too can not get into bios. I have unsoldered CMOS battery and resolderer and still no response. I have noticed that Acer has a hidden Active X file in system32 that may be an interactive file on how the system performs. I do not know anyone that had an Acer for more than 2 years. I think Acer has included a bug in their systems to corrupt to function of the motherboard. I am always working on computers and I have never seen this happen to see many people on these forums online. I am researching Acer computer now and will probably find the problem. My usb mouse lights up but do not move the mouse what so ever. I would recommend anyone not to buy. Once out of warranty the only voice you will hear before speaking to Tech Support is Credit card # and 2 dollars an hour charge and that may not help. I really believe that Acers lauch manager holds the info I need because there was an activeX file call lunch.dll that they have recently added a patch.

The batteries on these things are usually located under the wireless card. In my case as well as I am sure his, this is soldered to the board. I can unsolder without a problem but dont want to unless I know for sure this will do the trick. Personally I am working on the Aspire 5100 w/ media edition. It stops at Setup is starting windows. Microsoft gives a floppy startup download but without the USB's responding I cannot access the fix. In bios it shows the USB Floppy as the first boot up option. But if you press F12 for boot order It does not show a floppy as a choice so I figure it is acting like it is not there cause the bios has to be reset in some way. However when I got the system the date was on the manufacturers date already so I assume someone already tried to reset the board.

Same problem for me too. Keyboard and touchpad not working.
Also external usb mouse and usb keyboard not working too.
CMOS reset not resolve the problem.

Remove battery and power supply. Hold power button down for one minute. Reboot without battery.
I did this after having the unit powered down for two days.
Seems to clear the bios.

I have a question for you.. if you hold a button down on the keyboard or continuously press buttons on the keyboard over and over during setup... do you get that beep. Normally the computer will beep if you press a key too many times during setup, because it will think that the keyboard is broken or a button is being held down.
Can you hear this beep?
Also do you know the boot sequence on the laptop? cd, floppy, etc... is it default?

what are you referring to usb is gone ?
restart you computer tap the f8 key repeatedly to enter safe mode where the only things working will be your keyboard and mouse allowing you an attempt to repair your computer
If done properly the user should get to a screen similar to the below screen.
Select the option for Safe mode command prompt only
Windows Advanced Options Menu
Please select an option:
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Start Windows Normally
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice.
select safe mode
Click start control panel keyboard hardware make sure you have the right keyboard selected
or you might have uninstall the keyboard then restart your computer then reinstall it and its drivers
click start control panel administrive tools computer management device manager scroll to keyboard you might see a yellow question /exclamation mark ? ! or a red X right click update driver
hope it helps
