Hacking NDSL stopped to turn on

[apa-sf]

After last trip my friend's NDS Lite stopped to work - it does not turn on at all. He was playing it on a train, go asleep, and in the morning, after switching from one train to another he discovered, that NDS stopped to work and some thing has got lose inside (you can hear it when shaking the NDS).

What could it be?

OK we menaged to get inside of this faulty NDSL. One condensator (just under the "A" button on the other side of mainboard) felt off (how, why - we do not now ;] ).

Solding it again in old place helped and DS is working like new.
