Magsafe charger only works intermittently

So this is my second time posting the following, as it got deleted and completely disappeared (even from my own posts in my profile).

I own a 13" white 2007 MacBook:

Model Name: MacBook
Model Identifier: MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB

Bus Speed: 667 MHz
Boot ROM Version: MB21.00A5.B07
SMC Version (system): 1.17f0

My girlfriend has a brand new MacBook Pro from this summer.
Both our computers suddenly started behaving weirdly about a week ago. I'm writing now on 5% batter power so I'll make it short. We have tried everything but our chargers just don't work properly. We have about 3 chargers and 5 heads/cords and all combinations have failed to yield result more than once. I have restarted my computer, taken the battery out, restarted PR-things and SMC and I have cleaned the heads and I have even tried to install an update from Apple but it told me my mac didn't need this update.
So what the * is wrong with the magsafes? It's a real pain because we can have them working for many hours as long as we don't touch them - then if we move or want to unplug the charger for even just 1 second, they might not work again for 2 days.

So please help us. We're both writing our BA theses and need our computers working. Thanks!

PS: I received a message telling me this was a duplicate but it is not the same issue addressed by most people here because we are using both L and T shaped magsafes and it makes absolutely no difference. Both behave stupidly.

I swear I'm about to go insane. So my computer just died at 0% and I plugged the charger in and out maybe 50 times in different orders, spots in the house. Then suddenly i started working. I'm sitting here with 28% and BOOM, stops working OUT OF NO F ** WHERE.

If this was happening a few hundred years ago I would say that my computer was possessed by the devil himself.

I'm not an expert, but the fact that my girlfriend's brand new MacBook Pro is having the exact same problems as me, and with 3-4 different magsafes...
