HP laptops have the ability to lock the blue special function keys on, making numerical data entry easier on laptop models that do not have the room for dedicated numerical keypads. Because the key combination to lock the function keys is so simple, however, it is easy for those who wouldn't normally use this ability to do so accidentally. When the function keys are locked, pressing certain keys will result in numbers being typed rather than letters. Unlock the function keys to alleviate this issue.

Press the "Fn" and "Num Lk" keys on the keyboard simultaneously. The "Number Lock" indicator light should turn off, indicating that the letter keys will once again type letters when pressed. This combination should work on the majority of recent HP laptops. If it does not, try one of the alternate key combinations in this article's remaining steps. Press the "Fn" and "F11" keys simultaneously, then attempt to type a letter. If the combination does not work, continue to the next step. Press the "Fn" and "Scroll Lock" keys simultaneously, then attempt to type a letter. Continue to the next step if this does not work. Press the "Fn," "Scroll Lock" and "F11" keys simultaneously.

Some keyboards will have a light that goes on when caps lock is turned on

Hi
The usual lights for a keyoard are the 3 above the number pad. they will be labelled to correspond with the following keys:
- CAPS Lock
- NUMBER Lock
- SCROLL Lock
When they are pressed once the light will go on, meaning that function key is active. So if the CAPS Lock key was pressed and the light is on, then any letter key (A to Z) you press appear as a capital in documents. Press CAPS Lock again and the light goes out and the letter will type lower case.
The NUMBER LOCK is for the keypad to the right (not the number across the top and above the letters). This function ensures the numbers will appear instead of their alternate function, such cursor and Page UP/down, Home, and End.
SCROLL Lock is not used much, but it can be used in Excel to hold the current selection. For example, you want scroll about the sheet using the cursor keys, but want to keep the current cell selected. So with SROLL lock active, when you use the cursor key's, the sheet will move in the direction you want while leaving the selected cell selected. Try it and you'll see what I mean.
I hope this helps.

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

Solution: Type a letter and press the 0 key. Happened to me too.
