Keys on keyboard not working

From your description I must assume that if all other keyboard functions and keys work properly then the keyboard is faulty. For the number keys to print the upper case characters shown on those keys requires a shift key to be depressed or stuck. If all other keys work properly, replace the keyboard. Otherwise look for a stuck shift key. I have found keyboards for sale on Ebay.

Either the keyboard or the ribbon cable connecting the keyboard to the mainboard is damaged or not fully connected.

The most likely problem is the keyboard is defective. They are not very hard to replace. In most cases you have to remove the button cover above the keyboard and then the screws for the keyboard will be accessible. You can get a new keyboard off the Internet (EBAY or such) or direct from HP.

1.Make sure the "Caps Lock" key is not on. Though this will be obvious to most people, if your keyboard is typing in only upper-case letters it can't hurt to check. Look at the "Caps Lock" indicator light on the top right corner of your HP keyboard. If the light is on, strike the "Caps Lock" key on the left side of your keyboard. This will turn the "Caps Lock" off, allowing you to type in lower case letters again.

2.Make sure the "SHIFT" keys on your HP keyboard are not stuck. Dust and dirt can build up on a keyboard over time, which can cause certain keys to stick. If either of your keyboard's "SHIFT" keys get stuck, your computer will type in only capital letters. Use a toothpick or cotton swab to remove the gunk from the key, which should help it return to its normal position.

3.Unplug your HP keyboard and then plug it back it. This will remove the device from your operating system and then automatically add it back in. This can have the same effect, essentially, as restarting your computer. If your keyboard was typing in capital letters due to an error being stored in your operating system's memory, that error will now be cleared and the HP keyboard will function as normal again.

4.Update your HP keyboard driver. Click "Start" and then right click on "Computer." Click "Properties" and then "Device Manager." Right click on the listing for your keyboard and then click "Update Driver." This will update the computer software that is associated with your HP keyboard. If your keyboard was typing in all capital letters as a result of an error with this driver, the error will now be fixed and you can use your keyboard normally again

Hi,

That UP arrow refers to an UPPER CASE letter. If ever you press the CAPS LOCK key, it should turn off, if it does not it means the CAPS LOCK key for some reason is stuck. Try restarting the computer and by then the CAPS LOCK should be disabled.

Please let me know if it helped by selecting YES. Thank you for choosing FixYa! Your rating will help me succeed and continuously help a lot people.

If this is hardware problem, it'd be hard to repair. I don't mean it's not repairable, but what i mean is i don't recommend since repairing a keyboard and purchasing a new item will cost you more or less the same.
Well try this, Press Fn + Numlock (simultaneously on both the keys) on the keyboard and check if it helps or not [press once and then type the malfunction keys, if not press twice or thrice]. Most keyboard with Fn key's functions can be deactivated or activated with this key combination.
Good luck.

Thanks for using FixYa.

When you say it gives you an error, do you mean an actual error message, or the lower-case letter?

I have no idea what your experience is, so I'm asking if you know the difference between the Caps Lock key and the Shift key? The Shift key has to be held down while pressing the other key, eg h key to get H.

Pressing the Caps Lock key locks into upper-case, SO YOU GET A LINE LIKE THIS until you press it again.

I had the same problem.You will need a new keyboard. They are only $20.00 on eBay. Easy to replace.

use your upper case i for lower case, and a upper case i and an underscore for the upper case I_etter.

press caps lock and F9 together see if that fixes it

Hi,

Try reseating the key board.

Check whether the keys are stuck especially the shift,alt,caps lock. 

Hav you spilled any liquid on the keyboad.

Try uninstalling any software you installed for the keyboard and remove it from Device Manager (Click Start-Run-Type devmgmt.msc and click OK).

Reboot and see if that helps anything. Also, check the right shift and make sure it isn't stuck and check the keyboard settings in the Control Panel

Update the keyboad software from the microsoft website.
