Keyboard issue with Dell lattitude E5400

I am facing problems with my Dell lattitude E5400 laptop keyboard. I got it 4 months ago from Dell India. While typing, the cursor position changes. Sometimes laptop reacts differently to my keystrokes than intended. E.g. while typing a mail, suddenly the mail will be sent in the midway. This is annoying and I end up sending incomplete mails. My other colleague who uses the similar laptop also facing the same problem. Since I am in Japan for a 3 month assignment, I have to wait till I go back to India to get it serviced by Dell. My laptop does not carry international warranty. Any help on how to fix this?

Dell Studio 1737 with Back lit keyboard but Cap Lock Doesn't Light, replaced Keyboard less than 3 months ago, light worked then and went out just recently.

I'd try a different keyboard and see if the caps light works on that - so you can confirm whether it's the keyboard, or computer.

2. Boot to BIOS (F2 at boot) and in the maintenance section, reset BIOS defaults
3. If Dell Control point is installed, ensure Airplane mode is OFF in Connection manager

My keyboard doesnt work.I have to use an external keyboard.

Have you checked your interner keyboard in BIOS, Try turning on the system and keep tapping F2 , see if u see a diffrent screen then normal. and try playing around with the keys. if it works then it is not a problem with keyboard , but if it is then, you need to purchase a new keyboard.

Note/:- while exiting the F2 screen,.do not save any changes.

Keyboard problem in Dell Latitude PPX C Family

Actually this is a common problem with these Dell's. I have never found a cure for it other than replacing the keyboard. Fortunally they are not expensive, you can usually get one off of eBay for around $20 or so.

Hope this helps

This is a rather old question, but the solution might still be helpful to other readers.

I suggest you call Tech Support at Dell...

Several years ago, I worked on many Dell CPx 500 models in my work place. There was an issue that always involved a series of 4 or 5 keys (they were always the same keys) that would quit working and we had attempted to purchase new keyboards to fix the issue. It turned out, the real solution was to replace the 'motherboard' of the Latitude notebook!

Dell had knowledge about the keyboard/motherboard issue that we didn't know.

Dell Lattitue C400 keyboard partially not responding


If you have replaced the keyboard and still the issue is there, then you are right. The controller is shot. You need to replace the motherboard again for this type of issue.
