I have read through previous posts regarding this subject but none seem to be similar to my issue. I have, for the past year, had some difficulty getting the power button to turn on. There are no beeps and I have used both with the power cord and without it.
Generally what I have to do is jiggle the laptop top or move it back and forth. This leads me to think there is a lose connection somewhere. It usually turns on but I should mention that I also usually turn off laptop by "sleep" not off. However, today I used "shut off" and had a very difficult time getting the laptop power button to turn the system on. It is totally black and definitely shut off. After hours I guess I jiggled the top in the right position and it came back on.
If you could share some thoughts about what the issue might be I would appreciate it. I didn't know whether to return it to Dell for repair or find a local repair person here in Pittsburgh. Obviously it is several years old and I don't want to pay a fortune to repair it.
