- Safe to use 17v adapter on 19v laptop?
- Posted by Broons Bane on August 8th, 2006
I don't have my laptop power cable with me, but I can borrow one for
the week I will need it. The borrowed one is ok amp-wise, but it is 17v
rather than 19v. Is it safe?
Thanks in anticpation

There is some risk but it's small (it would be worse if you were using a
19v adapter with a 17v laptop). 17v is only a bit over 10% low, you may
get away with it. The battery may not charge, however, especially with
the laptop on. Again, keep in mind there there is a small risk of doing
damage, which you have to accept if you try this.

The most important thing is the correct polarity. Amps don't cause a
problem - too many and the excess are not used, to few and perhaps the
battery won't charge or the adapter will overheat (bad, I suppose 
).
But do check the polarity (and voltage..which you have thankfully).
