Acer TravelMate 8481T Keyboard Malfunction

May 17, 2018
Hello! I have an Acer TravelMate 8481T laptop and suddenly my keyboard not working properly. Sometime at the first start up the keyboard can't type any word but number but when i does it hold down the key down long enough until i press the caps lock, and then the caps lock button turn on by it self at the same time with a button beside the power button

Button beside the power

and also the wifi driver cannot turn on anymore. I have tried to re-install windows, do some cleaning all the hardware (including the wifi chipset) still nothing changes

Anyone have any suggestion?

Pardon for my english

PS: this solution still not working tho:
That solution has more than one solution in it. :) I am assuming you mean the remove driver/reboot/reinstall driver part. Did you try an external keyboard? And if so, did it work? If it works, then the attached keyboard is probably going to need replacing.

In regard to the WiFi not working, tTry this....

1. Go to "Control Panel".

2. Next go to "Network and Internet" and then "Network and Sharing".

3. Now click on "Manage Wireless Networks".

4. On this screen, remove all wireless connections by "right clicking" on it and select "Remove network" from the drop down menu.

5. After doing this, close the open windows and reboot the computer.

6. Once the computer is fully reloaded, scan for the "WiFi networks".

7. Click on the available network that you want to access and select "connect".

8. It takes a moment, but then you will be asked to give a password for your WiFi connection. Type in the password and click the "connect" button.

It should now be connected.

NOTE: If this doesn't work, you may want to reset your modem/router, and then once it is fully loaded again, repeat the above steps.

If this doesn't work, test seeing if your laptop will connect via Ethernet. If so, then your WiFi card may be going. You can either look to replace it/have it replaced, or get an external (plugs in via USB) WiFi card.

Another way to try it is to...

1. Go to "Settings".
2. Click on "Network & Security" and then click on "WiFi".
3. Now click "Manage known networks".
4. Select the WiFi connection you want to remove.
5. Click the "Forget" button.
6. After doing this, close the open windows and reboot the computer.
7. Once the computer is fully reloaded again go to "Settings".
8. Click on "Network & Security" and then click on "WiFi".
9. Now click "Manage known networks".
10. Click "Add a new network" and enter the network name.
11. Using the drop-down menu, select the "network security type".
12. Check the "Connect automatically" option.
13. Now check the "Connect even if the network is not broadcasting" option and click "Save".

Once you have completed these steps, whenever the device is within range of that particular network, it should automatically connect to it.

Also, you might want to check that both your modem/router doesn't have a limitation on how many devices can be connected at once (they do have that option in most cases) and also your ISP. Some of them limit the number of devices.

Hello! thank you for the answer
But still no changes at all..

I just bought a new keyboard for the laptop but still malfunction..also the wifi
I tried to re install the wifi driver it didn't work
The last time i re-install the windows the wifi work properly but after the keyboard error the wifi goes error too
i already tried on win764bit and win1064bit but still no solution
the only good news is the external keyboard is working

notice anything on the picture? i don't know what that button for but what do you think? every time the keyboard error this button is turned on by itself
If the external is working but the attached isn't I would say it is the attached, but you said you replaced it and had the same problem. The only other thing I can think of is it being the keyboards connection to the motherboard.

In the case of the WiFi, if it still refuses to work, it could well be the WiFi card. Have you tried connecting via Ethernet to see if that works?

Is there anything i can do about the keyboard connection to the motherboard?

The ethernet works fine
And i also tried to use external wifi receiver, works fine too

I don't really know what that is
but i also think that is a mark of liquid..

oh after i use the keyboard again, there is no problem only for the moment and then error again

okay seems we already got the root cause
i believe this is not repairable

Thank you very much @webworkings for giving a help
Really appreciate it!
