I’d like to know if it is okay to use a different power charger for my netbook. Originally, the charger specs are 19v and 1.58A. This charger is not available anymore and I can only find a 19v and 2.15A. Can I use this as a replacement?
Yes — with a couple of caveats, of course.
If it’s not made specifically for your particular computer, getting the right power supply is important, and involves matching voltage, amperage, and polarity.
Each have different constraints.
