Is it safe to use a power supply with a different laptop?
I've recycled a acer laptop from a friend, but original power adapter is lost.
I'm planning to use a spare dell adapter.
Laptop requirements : 19v, 4.74A Dell adapter : 19.5v, 4.62A
I will not using the battery at all, so I guess that power consumption will be a bit fewer than specified.
Is there an electrical risk ? or fire risk ?
