When i turn on caps lock, scroll lock and num lock, the lights do not turn on, but all these button are working. My computer is "Lenovo N500" and my windows is "Windows 7". So what is a problem? Maybe my computer is bad or it is not enough drivers?

Start the computer in safe mode. See what happens.

Hi, If you are using a keyboard that is wireless im sure you just have to change the battery on the keyboard.
However if the keyboard is connected to your CPU, then depending on your keyboard model, you may have to turn F LOCK (F Lock Light on) to access system key commands if they are labeled on the front of the keys, such as num lock , scroll lock and print screen.When you click on the Flock, the lights are either supoosed to click on or off.
view the keyboard status lights by using the On Screen Display (OSD) option, Ensure you download the software ,
from your start menu do a search for your keyboard, on th key tabs setting,
its important to make sure that the correct model number is entered,
double click on the light you wish to change, in the Reassign a Key wizard,
clear the Displays (key name) status on the screen check box to disable the on-screen display, or select it so that a check mark is in the box to enable it, and then click Finish.
HOPE THIS HELPS.

Num Lock ----- Cap Lock ---- Scroll Lock

• Num Lock --- use numeric keypad
• Cap Lock --- all capital letters
• Scroll lock --- stop screen from scrolling ( pause screen )
  

Due to some internal error and fault in RAM this happens

i believe you have the "num lock" button on. push it again the light sghould go off and now its all letters now

Boot to your Bios and look in advanced for num lock and disable.

or

go to run in the start menu.
typ: regedit.

Go to: HKEY_USERS\.Default\Control Panel\Keyboard
Then String value- InitialKeyboardIndicators right click click modify then choose a number below.

Explaination numbers.

0= Truns Off, Num Lock, Caps Lock, Scroll Lock
1= Turns On Caps Lock,
2= Turns ON Num Lock,
3= Turns On Caps Lock, and Num Lock
4= Turns ON Scroll Lock
5= Turns on Caps Lock, and Scroll Lock
6= Turns On Num Lock, and Scroll Lock
7= Turns On Caps Lock, Num Lock, and Scroll Lock

Hope this helps.

When you start your PC, Num Lock, Scroll Lock, and Caps Lock don’t automatically toggle on. You can automatically turn each of them on or off whenever your PC starts, for all accounts on the PC. As a practical matter, most people probably want to have only Num Lock automatically turned on, but this Registry hack gives you the power to force any combination of keys on or off.

Start>Run then type in "regedit" whithout quotes.

HKEY_USERS.DefaultControl PanelKeyboard.
Find the String value
InitialKeyboardIndicators. By default, it is set to 0, which means that Num Lock, Scroll Lock, and Caps Lock are all turned off. Set it to any of the following values, depending on the combination of keys you want turned on or off:
0 Turns off Num Lock, Caps Lock, and Scroll Lock
1 Turns on Caps Lock
2 Turns on Num Lock
3 Turns on Caps Lock and Num Lock
4 Turns on Scroll Lock
5 Turns on Caps Lock and Scroll Lock
6 Turns on Num Lock and Scroll Lock
7 Turns on Caps Lock, Num Lock, and Scroll Lock
Exit the Registry. When you restart, the new setting will take effect.

Note: You have problem with Caps Lock so just modify Caps lock option on Regedit.
And do not forget to run virus scan on your computer once you are done.

Rate always the all answers.

Thank you

The 3 LED's (Num Lock, Caps Lock, Scroll Lock) are used by Dell to diagnose no-post issues such as yours. The only error code close to yours is [Num Lock ON, Caps Lock FLASHING, Scroll Lock ON]. This indicates a a memory error. Try reseating the memory modules. If you have 2 memory modules, insert one at a time to determine the faulty module.
