Dell Alienware 17
The power adapter cycles from detected to undetected every 30-60 seconds or so and battery tends to stay not charged.
I have replaced the adapter with new one and same thing. Does it when just in BIOS, booted to Windows or even turned off (can see from the power lights on the laptop)
This started happening with no apparent reason whatsoever.
I have taken apart the laptop to look at the jack and no apparent damage or loose wire.
This happens at a fixed interval and doesn't seem to be random at all.

Sounds like it may be a battery problem. How old is the battery? Dell has a pretty good diagnostic that should tell you the health of your battery. Could also be a failure in the power supply (part of the MB).
