This happened to me on my NEC Versa M300 so I took the keyboard off and swapped it for my brother's (we have the same laptops) and the replacement one works fine. I think a terminal on the connector gets dirty or corroded.
Hi, open the control panel, switch to classic view, double click the keyboard icon and check what speed the repeat delay and the prepat speed are set al. you can adjust these with the two sliders and it gives you a place to test your settings befor you click ok and commit to them. Hope this helps
Take the computer to a qualified technician, who can replace the keyboard, as the least-expensive "try" at trouble-shooting.
Since a keyboard transmits "codes" to the motherboard,
e.g., left-shift-has-been-pressed, and left-shift-has-been-released,
and the motherboard interprets those codes, it is NOT likely that
the motherboard is misinterpreting the codes, especially given that
the "bad' letters are in a straight line on your keyboard.
Find an external USB keyboard, and plug it in.
If it works correctly in the first 15 minutes, then the problem is NOT the motherboard.
This could be an issue of a wear and tear, you could run a test on the keyboard:
1. Turn on computer 2. Tap F12 3. Select Diagnostic 4. Follow the on screen instruction (until test finished aproximately 10-15min.) 5. If prompts " do you want to run remaining memory test 6. Select " No" 7. Select Test System 8. Select Custom Test 9. Run keyboard test
If there is an error message about the keyboard it means, you need to replace it. If you are still covered by the warranty, just call dell techsupport and they will replace the keyboard. Hope this helps
