Dell External keyboard arrow keys not working.

There were not answers on this website, but I started trying keys and found the ''Scroll Lock'' key had been activated so that the arrow keys would only move the place on the file instead of from cell to cell. Live and learn!

Try unplugging and replugging keyboard. If that doesn't work, save your files to a flash drive or external hard drive, then go to:
  1. Start
  2. Control Panal
  3. System and Security
  4. System - Device Manager
When the Device Manager comes up, look for "Keyboards" Click on the little arrow to the left of it. If there is a problem, you will see red or yellow markings.
Right click on the keyboard listed and reset it.

Why aren't arrow keys working on keyboard

1. is you numluck key pressed (or the light is on)?, press it again
2. try to replace your keyboar for a known good keyboard. (ps2 or usb).
3. it may be a driver issue. go into the manufacturer's website and look for an updated driver for your keyboard controller. (ps2 or usb).

hope that gives you a good start to troubleshoot the problem.
(the options offered should be attempted in that order).

good luck!

Microsoft Wireless Multimedia Keyboard 1.1 not working

Could be spyware or a virus. Try this.........If this does not help let me know.

Turn the system restore off. System restore keeps everything in restore. Meaning......... If you have spyware or a virus, it will stay in your system. Run Spybot S&D (This program is free and is better than using msconfig as long as you go through the settings and change everything to the highest settings.) Then do the same with Adaware 2008 (sounds stupid to use 2 things for spyware, but one catches what the other one does not.). I have links on my website ( These links go directly to the download so you will not get the run around. You would do good to try a program called Window Washer. This is a great program that completely cleans anything in your computer that you do not need. It will not clean out anything that you have to have. I have used this for years to clean out my customers computers and have cleaned as much as 3 gigs of trash out. If you contact me I will give you some tools that I have for free that will do a great job on your computer. I have them ready to download and I will give you the link. (

Window Washer free Download.

Keyboard buttons

Hi Grumpy Gran
Great name by the way. Are they listed top to bottom ` a two headed arrow, caps lock, an up arrow and ctrl?
These are not particular active keys. If you have used a typewriter the two headed arrow is the tab key, use it to jump a given number of spaces to the right.
The caps lock will set your keyboard in capitals mode. The uparrow is the shift key which temporarily puts it into capitals or vice-versa. The ctrl key is a special key which is not used in normal typing. You may not need it in normal use.
Good luck with your surfing.
ps its not a good idea to unplug your keyboard whilst the computer is still on. You should connect it when the computer is off so that it is detected when the computer starts.
