My laptop's cable broke and sadly it seems like I need to buy a new power supply.
What I wonder is, I've found that universal power supplies are much cheaper than the official HP ones. Are they really worth it?
Another question: the original supply has these specs: 65W, 18.5V, 3.5A.
However the universal supplies are more powerful (90W, 100W) and come in integer voltages (17V, 18V, 19V, etc). Are they compatible? Should I set them to 18V or 19V?
