Solved can i use a 19.5v adapter instead of 16v

Specs: Windows 7
Hi
What would happen if someone has used an incompatible "generic" 19.5V adapter with 4.7A & 90W on a Sony Vaio netbook that required a 16V adapter with 3.75-4.0A & 65W.
I'm asking because someone bought one from me and tried to use an adapter that was not listed as compatible with the netbook model and is now saying it doesn't work! I would have thought that it is highly likely to have caused damage to the circuits etc, but I'm no expert so would appreciate any advice.
Thanks

✔ Best Answer
You forget to list whether the adapter is AC or DC out. If DC, is it negative or positive tip? Even if the adapters are same AC/DC-wise and the tip polarity is correct, it's never a good idea to go much above (5%) the stated voltage (16 vs 19.6 is a 22.5% difference), especially for something like a laptop. The charge circuit could easily be damaged (as you suspect).

Hi
Sorry - they are both AC adapters

Thanks. I think I'd be a bit wary of suggesting he tries using the correct adapter in it now in case it bursts into flames!

So then, you sold a laptop without the AC adapter?

Your house could burn down.

You need to get an adapter that is EXACT for your system.
