New laptop time?

The power connector on the motherboard side of my Dell laptop is starting to flake out. More often than not now, the laptop ends up running on battery power even though it's plugged into the wall. After a quick perusal of the Dell support forums, it seems to be a fairly common problem requiring a motherboard replacement.

So, do I see if I can get it repaired, or try to convince the higher-ups that I need a new laptop...
