Keyboard tounc screen usb not working

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.

Re: Keyboard tounc screen usb not working

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.

Re: Keyboard tounc screen usb not working

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.

Re: Keyboard tounc screen usb not working

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.

Re: Keyboard tounc screen usb not working


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?

Maybe your keyboard is bad and needs to be replaced? Did you spill a liquid on it?

Maybe the keyboard has been hijacked by a virus or infection.

maybe the keyboard cable needs to be reseated which means taking the keyboard up and removing then putting the cable back in. The cable is under the keyboard.

Have you tried booting up in safe mode to see if the keyboard works?
Turn off the computer, then hit the power button to turn itback on and immediately start hitting the F8 key repeatedly until you see SAFEMODE. Take the Safe Mode option and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal.

How do I fix or repair my HP mini 1000 Netbook with it being stuck in a boot loop? I am getting the "unmountable_boot_volume screen. My netbook does not have a CD ROM drive.

Check your bios to ensure its first boot option is set to the hard drive instead of CD drive or USB drive. If you have a thumb drive plugged in, unplug the USB and try again. On your boot screen there should be an option to hit a key to enter bios (Usually Esc, F2 or Del). Hit whichever key it requests and enter Bios. Once in Bios look for Boot Order and check to see where the Hard Drive is in the order. If it is not set to #1 then do as it says to set it to the first option. Once done hit F10 to save and Exit and return to boot.

When I switch on my advent laptop, it freezes and then there is a big ADVENT across the screen and at the bottom it says "press . <F12> to enter setup, <F12> to enter Multiboot Selection Menu"....

Is there any error messages? Is your keyboard working? You can try F2 to enter the setup and see whether you can see the boot options and maybe you can press F8 at startup and use the safe mode to perform a system restore or use the Last Known Good Configuration option in the advance options with safe mode.

Acer Aspire 5100 Notebook Boots to Windows, but nothing works. No keyboard, no mouse, no usb or CD, no external monitor. I have an Aspire 5100 Acer Laptop that has no keyboard or mouse function period...

Try booting your computer from CD ROM with the OS CD/DVD already inserted and when prompted just try repair. If that does not work re-install the same on the same 'partition' assuming it to be C by deleting the the windows system files only. While doing so keep the internet on and immediately after the basic version of the OS is installed and the m/c boots-up for the first time, go to the official website and download the latest drivers for every component like toch-pad, keypad, display, audio, etc.(i.e. almost all the drivers)

After booting process done. Screen goes blank and Keyboard not working only Mouse cursor is dispaly and working on the blank screen in My acer Laptop.

Try booting the system to Safe mode.

To boot to safe mode:

Restart the computer. As soon as the BIOS has finished loading, F8 key on your keyboard. When Windows Options menu appears, scroll to select the Safe mode menu item, and then press Enter.

Select "Last known good configuration" then press Enter.

If that doesn't work reboot again and keep tapping on F8 to Safe Mode and instead of selecting "last known good configuration" select "Repair Your Computer"

Or you can try this:
Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";}
  1. Place your Windows XP set up disk in your CD drive.
  2. Turn off your computer and change your BOOT order to boot from CDs first.
  3. Turn your computer back on.
  4. Press any key on your keyboard when it asks you to.
  5. Press enter when you see a blue screen, one of the options should say, "To setup Windows XP now, press ENTER.".
  6. Press enter to start the windows set up.
  7. Accept the Licence and Agreement and confirm that the setup is searching for current versions on XP.
  8. Press "R" when the set up has found your current version of XP.
  9. Notice that the Set up is deleting all your windows xp files and replacing them. (This will not cause loss of data)
