I snagged a Game Gear today with a few games on the cheap. With the AC multiadapter provided the thing works perfectly. The trouble is, I put in a standard set of 6 AAs, and the thing won't last a minute before the power light starts blinking. This happens no matter what batteries I put in, but works fine running from the power adapter. I know Game Gears are notorious for draining AAs within a few hours, but a minute?

Please help, it's no longer portable!

EDIT VVV - The power gives out after about thirty seconds, maybe a little less. I'll give the battery connectors a good clean, then try your suggestion.

EDIt#2 - Well, I've just written an angry letter to the supermarket I bought the batteries from. They were all dead, all 100 AA batteries.
