I have a Compaq Presario R3000T, three years old and out of
warranty. The pin in the power jack is loose, and it is extremely
difficult to get the computer to recognize the ac power is plugged in,
even on a flat surface. This happened before, and I got the pin re-
soldered. It ran smoothly for a month before the problem returned.
What should I do now? Get it re-soldered? I don't want to get into super-pricey replacement parts, but it's a good laptop (when it's on) and I'd like to keep it functional.
