Macbook suddenly switches off, and also not starting without battery

問題

The Macbook of my Wife suddenly switches off, with green light of Macsafe connector.

Also when charging, only short time charges, then switches to green.

When i took out Battery, Macbook won't start.

修理

1st replaced Battery by a new one. - but same thing.

Then i thought it might be the main board, till i read

some Articles here on iFixit about charging and mac-safe.

Ordered the DC-Inboard and voila.

All working now perfect.

アドバイス

Never thought when Macsafe Connector is green,

and Macbook has no Battery in it, it won't boot with this faulty unit.
