Would it business if my PSU for my laptop is rate at 19V =3.42A and I used 19V=4.74A?
Answer:
The component is rated to produce 3.42 amps max. If your system draws more current afterwards that, you are overloading the power supply. It may work for quite some time tho. Beware tho, dont vacate it unattended and make sure its turned bad when not in use.
Are you adage you're using 4.74amps? Or you want to get a power supply rate at 4.74 amps? If you're using that much then you could burn up your power supply or even own problems with other hardware. If you're going to return with a new PS afterwards it would hurt it, it'll only draw what it desires.
Are you using a power supply rated at 4.74A? Laptop solitary needs 3.42A? What's the problem?
At home when you plug surrounded by a light using 60w (.5A)...do you reflect on it will blow up just because the outlet can bar 20A?
