Using Power Adapters

  AP22 23:21 04 Jun 2006

I have just bought a new Sony VAIO and the power output on the adapter is 19.5v. As it is rather a large adapter I want to keep a smaller, lightweight one in my briefcase. However the lighter one only has 19 or 20V settings. Will I harm my new laptop by using either of these settings?
Thanks in advance for any help.

Two important questions about the "smaller, lightweight" one-

Is it DC or AC - and is it the same as the Sony one.

What power rating is it, compared to the Sony one (how many amps?)

The Sony one may actually be a stabilised power supply (I don't know actually) - whereas others could be unregulated and unstabilised.

Be vert, very, careful - if your laptop is damaged, it won't be covered by the warranty.

It isnt worth the gamble. As DieSse says, there are so many potential differences in current, polarity, stabilisation, it's a minefield best avoided.
