I have been given a laptop, which does absolutely nothing at all - no lights on it, no fans, nothing.
The delta power adaptor has a green light on it.
As soon as it is connected to the laptop, it goes pale and starts blinking.
The power supply gives a steady 19.4V as per spec.
The laptop is an old packard bell of unknown origin, but it's running windows XP (from the sticker underneath) so it can't be too old.
Anyone have any ideas? I'm thinking a motherboard short?
