External keyboard doesn`t work

I have an Acer A. 7720 using as a desktop replacement. I want to have an external keyboard. I have tried two already. None of them worked. I used a usb to ps2 adapter. Can it be the problem? (Someone told me that there are different circuits in the usb and ps2 keyboards/plugs) When I plugged in the keyboards nothing happened. No lights on the keyboard... I tried all the usb ports.
I use Vista. In device manager there was no sign that the Vista recognized the new keyboard.
Any idea?

p.s.
Shall I use a usb keyboard instead?

    the problem was the ps2 to usb adaptor. I bought a usb keyboard and it works well.
    I need to use vista on my acer laptop `coz the company doesn`t provide any drivers for winXP. sucks.

NUMERIC KEYPAD NOT SUPPORTED


Might give this a try-right click on your Computer icon-click on Properties-then click on Device Manager. The keyboard is listed there. If it has a yellow exclamation point, or a yellow question mark, then there is a problem. Click on the arrow in front of Keyboards, then right click on the drop down named keyboard. There you can click on update drivers. That should solve the problem.

Keyboard doesn't work


Try connecting an USB keyboard to your Acer laptop. If the external USB keyboard does not work the the laptop is faulty.
If the USB keyboard works then reseat the laptop's keyboard connector to the motherboard, it may have become loose.

I have an acer Aspire 7720 with an broken motherboard. I had ordered a new one, I had installed it and everthing is going ok except the keyboard. I have ordered a new keyboard but the same think.It's not...


Check the laptop is accepting keypresses by using an external keyboard. I'm assuming you were confident that this replacement board was working without issue when you bought it? What may have been working in all other respects, could have had a faulty controller on the motherboard.
I'd also check that the keyboard ribbon was correctly locked into place as you re-assembled it and there are no kinks in the ribbon

White screen on Acer Travelmate 7720


most likely you have a faulty LCD screen, the only option u have is to replaced it or u can use a external LCD screen to act as screen for your laptop. you'll be needing a VGA cable to connect your laptop to any LCD screen available.

The Numeric keypad on my Acer Aspire 7720 doesn't work. When I press Num Lock key the indicator light doesn't come on. The main keyboard works fine. I am using Vista.


try to access command prompt outside of windows using the operating system disc. (by booting to cd and go to repair your computer options then select command prompt) if the keyboard works fine on command prompt, there's no issue with the hardware. but if it still doesnt work, you will need to replace the keyboard.
