Acer Aspire 5100 Keyboard Not Working

Suddenly the keyboard stoped responding. The windows operating system is booting up fine but cusror is frozen on middle of the windows welcome screen and doesn't move. I tried every thing even trying to go to setup screen to choose safe mode using F2 or F12 but when I go there no key is working. Tried connecting the notebook to another external keyboard but that didn't work either. Please HELP, the laptop is only 2 yrs old and I am surprised to have this issue. Please tell me what should I do.

this is a common fault in the acer aspire 5100 series, also in few other series, 3102wlmi, I have it here. same issue as you. I ordered a new keyboard for it but Haven't tried it yet. unlikely to solve the problem. I beleave the issue is on the motherboard.

Touchpad and keyboard are dead on my 3102 also. I will try the new keyboard on Thursday and get back to you if it solved the problem.

possibly the only fix that can be performed at home is to replace the whole board, most computer repair shops will also just replace the motherboard.

it will require a close inspection on the motherboard, have you already contacted acer? I think the price of a new motherboard at is around 200-500 usd I haven't checked myself.

    acer laptops are really poor quality.

    I got my first acer back in 2003, acer aspire 1522wlmi. the laptop broke down every 10 months. the vga board was replaced two times ones under warranty and 2nd time I had to pay for it myself.

    then I sold it.

    acer aspire 3000 and 5000 series atleast have this fault in common with the keyboard and touchpad, who knows what other faults they have.

    Really poor quality, maybe a plan to keep the company in business by having the customers buy new parts or new laptops ever year or two?

    I suppose I may have just been lucky, though I've managed to have my laptop last over 6 years without many problems at all. But I've finally hit the same problem. Was browsing websites when I thought my computer simply froze. So I tried to restart the computer only to find out there was more to the problem than that. Hoping its just a loose connection or something, but I'll find out

Several keys on my Acer Aspire 3680 (P, Q, TAB, etc.) have stoped working. What is wrong, and how can i fix it?

you can check ebay for a new or used working keyboard and replace it yourself. most keyboards are easy to replace. MIght be some screws on the bottom holding the keyboard to the laptop or the up area of next to the LCD will pop off and there will be screws under that to allow you to replace the keyboard. just be careful with the ribbon connection on the motherboard some of these are thin and easy to break.

Sounds as though you have changed it to a US keyboard by accident. Go into Control Panel and Check in Regional & Language Settings for Keyboard.

Compaq 3702 keyboard not working

Try to go to the Bios of the computer..Power on the computer and hit F2 continuously until you reach the BIOS or blue page..If you were able to go to the BIOS it means that the keyboard is working..Also try to go to one time boot menu..Power on the system and hit F12 as soon as you see the ACER logo..It is also one way to check that the keyboard is not faulty..

If you weren't able to go to the BIOS or Boot Menu..You need to replace the keyboard and also the touch pad of the system but if you were successfully go to the BIOS or Boot Menu it's either the driver of the keyboard and pointing device or software conflict..

  • If you are using XP and you have the OEM disc..You can perform system restore inside windows or in the recovery console..Here is the link for system restore in recovery console
  • If this will not work you need to reinstall the operating (fresh copy, data deletion)

Acer 5100 keyboard and mouse will not work. No

Hello there, this is usually caused by one of three things.

Either something was just plugged in (usually USB) that is interfering that you can just unplug

The computer has locked up for another reason (more in a sec.)

Mainboard could possibly be bad / going bad =(

To test if the computer itself is locked up try plugging in an external USB mouse or keyboard to see if you can get that to work. If it does then that means the keyboard and mouse built in are failing, which again basically means the mainboard is failing.

Hopefully it will be that the computer is completely locked up so when you plug in an external usb mouse or whatever it won't respond. That's easiest to fix.

Please let me know

Keyboard is not working

Normal 0 Assuming that you have good batteries installed, turn the Keyboard over and locate the small reset/connect button on the back of the keyboard and press it. Then try to see if it is working. If not try pressing the button on the receiver and then on the keyboard. Try typing, should work okay.
Hope this helps. Bud

Dell Wireless Keyboard stopped responding, please help.

The keyboard should have a button underneath it. Press the button on the usb controller first and then the button on the keyboard. Repeat a few times to see if it connects. If you are still having trouble try another set of batteries as some batteries are not designed for wireless products.
