Question about Compaq Keyboard

1 Answer

Long story short: two keys stopped working

Recently I decided to take a 1990's NEC APC-H412 out of retirement. The alphabet keys had foreign-language stickies on them. It took Goo Gone to remove the gunk. When I plugged the unit in, I found many of the keys required unusual pressure or repeated once pressed. A few did not work at all. The Goo Gone probably caused this, but I got all but two of the keys to work by working a Qtip dipped in rubbing alcohol in and around the blue ovals and their 1/2" square bases. The two holdouts - Z and V - were slow at first; not they don't work at all however hard I press. Possibly I broke a connection to the IC board underneath when I lifted these keys. The unit is a gem, like an old IBM without the clacking and with a softer touch. I'd very much like to use it for a change of pace. Any suggestions?

Re: Long story short: two keys stopped working

I would completely remove the keyboard from the unit, it will be easier to clean and you can check to make sure that where your keyboard plugs into the board is tight, and that nothing in the cable looks cracked etc. Just be careful when taking it out, like dont bend the keyboard or be rough and know your keys off, they can be put back on, but its not an easy task, and takes patience.Most keyboards are easily removed by removing the strip at the top, usuall where the power button is etc. You might try just blowing it out really good first, maybe dust or a larger particle is caught under those keys.

Wen i hit the question mark key i get a big e how do i get the question mark to appear

Windows has support for "foreign" keyboards, e.g., Spanish, French, German, Norwegian, et cetera, that have different graphics for some of the keys.

Access "Control Panel", then "Regional and Language Options", and select the 'USA' keyboard.

I cannot get a question mark, the upper case E with a grave (green) on keyboard appears

When you get that it usually means the language setting for the keyboard has changed.

The standard key markings are valid for most english language settings. US is the default. To change this go to start - settings - control panel. Then look for Regional and language settings. Click on that and then in the window that open there are three tabs along the top. The middle one should say language, click on that one. In the Text Languages and input options area click on the Detail button. A new window opens. At the top it shows your language. And in the box under it will show your lnaguage and installed keyboard layout. So if I were using Canadian English and the US keyboard then the keys will function as marked. To change the keyboard language click the add button, then select your language and then the keyboard layout. When you click ok it goes back to the previous window but now will show the original setup and the new one you just made. Just remove the original and apply and close everything and your keyboard will now produce the correct characters.

Character keys problem

I doubt the keyboard itself is at fault. Try it on another computer and see if it does the same thing. If it works okay on the other system, then the Keyboard settings on your machine were probably changed. Go to the Control Panel and look at the Keyboard or Regional Options entry, and make sure that it is set to English. If your computer has foreign language support turned on, there may also be a control in the system tray at the lower right of the screen that has been changed from EN to some other language.

Yes. Get a new one! The keys are stuck when you apply too much pressure on them, and check for foreign objects between the keys. Use compressed air first, if that don't work you have the option to spend money to get it diagnosis at a computer shop or buy a new one.

Left shift + T, right shift + E doesn't work on an hiper keyboard

Your shift key is broken, if this product was recently purchased, return it for another. If you've had it for a while and it just decided to stop working, your best bet would be to pry the Left Shift key off and clean around that area and properly attach the key back on - its possible it wasn't hitting the sensor when it was pushed down.

If this does not fix your problem please leave a comment and I will assist you further.
