Laptop power supply question
My laptop came with a 45W, 19.5v, 2.31A brick that you can fry an egg on when charging the battery. Replaced the brick through warranty and the new one does the same thing.
Will buying a 90W, 19.5v, 4.62A brick hurt the laptop in any way?

However make sure that not only the voltage is a match, but also that the connectors are identical as there is not standards that mean for example the positive terminal is the same and if not that will kill your laptop.
If you post your laptop's make and model I can find you a link to a power adapter.
Switched to a 90w, 19.5v 4.61a charger but wanted to make sure it wouldn't hurt anything.
That sounds like it'll work great. Watts is calculated by multiplying the volts by the amps. Amps is the max current a device can pull. Volts is how much "pressure" is behind that current. You can always get a higher amperage supply as long as the voltage is the same. And I always recommend genine adapters, regardless of brand. I've seen too many laptops get fired by shitty power cords.
