I have a notebook with a defect power supply that requires 19V and 3.42A DC. I also have a power supply from an old laptop from a different manufacturer that generates 19V and 4.74A DC. The connector fits, which is already luck.
I would be really happy, if I could use that power supply with the laptop, if the minor difference in ampere 1.32A too much to be exact would not be a problem and potentially damage the notebook.
I don't want to try and fry it.
Should the power adapter work? If uncertain, should I simply try? Is there any risk that the bit higher ampere might fry some circuits in the laptop?
If it should work without any danger to the hardware, should I still get a matching power supply to prevent potential long term damage, if a higher ampere could cause that? You can drive a car in low gear too fast with too much revolutions per minute for a short period of time, but making it a habit will eventually cause damage to the engine. That's the equivalent to my problem that came to my mind. .... or shouldn't I have to worry about this and just use it without getting a replacement?
